The JBL Live 770NC Wireless are the top of the Live series of headphones, which are the step-up model from the budget-oriented Tune line. They represent an update to the previous generation, JBL Live 660NC Wireless, and are the over-ear sibling to the JBL Live 670NC Wireless on-ears. The Live 770NC come with active noise cancelling, spatial audio, and a host of custom EQs in-app. If you're overwhelmed by the vast JBL catalog, we don't blame you: mid-tier headphones like these can out-spec older flagship models that remain in production, further muddying the waters. To keep it tidy, we've broken down these ANC-equipped headphones to see where they shine and where they flounder.

Our Verdict

6.6 Neutral Sound

The JBL Live 770NC are okay for neutral listening. They can connect to different media players: you can listen to them with ANC regardless of whether you're using Bluetooth or the audio cable (if they're powered on), and they also work passively with the audio cable, resulting in a somewhat different sound with a more neutral bass. Their default frequency response via Bluetooth is an excited bass-heavy and trebly sound, and their companion app supplies a few EQ tools to carve out a different tuning if you prefer. While they have a spatial audio function, it's a basic implementation without head-tracking. Otherwise, their closed-back design can't create an open or immersive passive soundstage, and their fit struggles to deliver consistent audio, especially for people with glasses and thick hair.

Pros
  • Comfortable to wear.
  • Robust companion app.
Cons
  • Fit struggles to deliver consistent sound.
  • No high resolution Bluetooth codecs.
7.5 Commute/Travel

The JBL Live 770NC are a good travel and commute companion. Their long battery life ensures you'll reach your destination with plenty of charge left. The over-ears feel comfortable, and their noise cancelling helps reduce environmental sounds, even if it's not class-leading in effectiveness. Not much sound escapes the headphones, so you're unlikely to bother your neighbors on a flight. Their dedicated app provides creature comforts like listening modes and TalkThru if you quickly need to hear someone. They're over-ear headphones, so they take up real estate, and their carry pouch won't protect them from getting crushed by other objects stowed away in your bag.

Pros
  • Comprehensive controls.
  • Comfortable to wear.
  • Robust companion app.
  • Long battery life.
Cons
  • Fit struggles to deliver consistent sound.
  • Headphone frame is a bit creaky.
  • Carrying pouch won't prevent water or impact damage.
7.3 Sports/Fitness

The JBL Live 770NC are decent for sports and fitness. They're comfortable and stable enough for upright movements like dumbbell curls. Any controls you need are immediately accessible through their comprehensive controls, including a hands-free voice assistant, so you can ask Google Assistant where to get a protein shake. You have several listening modes to suit your activities, ranging from ANC for focusing at the gym to Ambient Aware if you decide to hike outdoors. Their build quality is good but a little creaky, so don't drop them. With that said, they're still over-ear headphones, so they're large, and like most over-ears, they don't have any water or dust protection rating.

Pros
  • Comprehensive controls.
  • Comfortable to wear.
Cons
  • Fabric headband can absorb sweat.
  • Carrying pouch won't prevent water or impact damage.
7.3 Office

The JBL Live 770NC are decent for office use. They feel comfortable to wear, although the tweed headband is a bit coarse if you're bald. Their battery life is more than long enough to get you through a week of work without needing a recharge. You can multi-pair to your phone and work computer for easy device switching. Depending on how loud you set your volume, they don't leak too much of your audio into the office. While they have ANC to help isolate you from typical office sounds like HVAC noise and background chatter, it's only okay. In addition, if your office requires a lot of online meetings, their microphone can cause your voice to sound somewhat muffled.

Pros
  • Comprehensive controls.
  • Comfortable to wear.
  • Robust companion app.
  • Long battery life.
Cons
  • Microphone quality isn't very good.
  • Fit struggles to deliver consistent sound.
  • Mic only works over Bluetooth connection.
  • Headphone frame is a bit creaky.
5.6 Wireless Gaming

The JBL Live 770NC can't connect wirelessly to gaming consoles, and their latency over Bluetooth is fairly high, although 'Video' mode can help reduce lag a bit if you're mobile gaming. Plus, the sound profile changes significantly when the mics are active.

7.2 Wired Gaming

The JBL Live 770NC are satisfactory for wired gaming, so long as you don't need to use their microphone system. They're comfortable to wear, and they work actively or passively when they're plugged in. You can still use their ANC (if the power is on) to help block out your environment to focus. Their active sound provides a lot of rumble and boom and a very bright treble response, whereas the lows are more neutral when you use them passively. That said, they don't consistently deliver your audio sounding the same way, especially if you wear glasses or have thick hair.

Pros
  • Comfortable to wear.
  • Long battery life.
Cons
  • Fit struggles to deliver consistent sound.
  • Mic only works over Bluetooth connection.
6.5 Phone Calls

The JBL Live 770NC are okay for phone calls. Their app includes a sidetone so you can hear yourself when speaking. The headphones have dedicated call controls, and you can set up hands-free calling. In quiet environments, your voice sounds intelligible but a bit muffled. If you try using the headphones in other settings, like on the street or in an open-plan office, they have trouble filtering out background sounds without distorting your voice. Their mic system only works when they're connected via Bluetooth.

Pros
  • Comprehensive controls.
  • Adjustable sidetone.
Cons
  • Microphone quality isn't very good.
  • Mic only works over Bluetooth connection.
  • 6.6 Neutral Sound
  • 7.5 Commute/Travel
  • 7.3 Sports/Fitness

Differences Between Sizes And Variants

The JBL 770NC come in 'Black,' 'Blue,' 'Sandstone,' and—like our pair—'White.' You can check out the label for our unit here. We expect these variants to perform similarly with only cosmetic differences. If you encounter a different variant of these headphones, please let us know in the forums, and we'll update our review.

Compared To Other Headphones

The JBL Live 770NC are like the over-ear fitting version of the JBL Live 670NC Wireless on-ears with a very similar folding frame and features. However, they block noise more effectively than the Live 670NC, even if their battery life isn't as impressive. Compared to the JBL Live 660NC Wireless over-ears, the Live 770NC have expanded controls, a longer battery life, and better noise cancelling. In contrast, the Live 660NC over-ears have a much more neutral sound profile by default and similar app functionality. Compared to pricier options like the Bose QuietComfort Headphones Wireless, the JBL Live 670NC can't outdo the Bose over-ear's comfort or ANC capabilities. However, the JBL have greater sound customization and double the battery life.

For more ideas, check out the best noise cancelling headphones under $200, the best noise cancelling headphones, and the best JBL headphones.

JBL Live 660NC Wireless

The JBL Live 770NC Wireless have an improved battery life and better noise cancelling than the JBL Live 660NC Wireless. While the two headphones share similar app features like EQ, the Live 660NC have a much more neutral sound profile than the Live 770 NC's excited bass-heavy frequency response. This depends on what kind of tuning you prefer.

Sony WH-1000XM4 Wireless

The Sony WH-1000XM4 Wireless have better noise isolation than the JBL Live 770NC Wireless. The Sony headphones support more codecs, like the high-resolution LDAC codec and AAC. Depending on your preferences, they sound bass-heavy but in different ways. By default, the Sony sound bassy, slightly muddy, and warmer. The JBL are even more bassy with more accurate mids and a much brighter treble. Both have excellent app support, including equalizers to adjust their sound to taste. The Sony are better built and comfier, meaning they're likely the better choice for most people. However, the JBL have a notably longer battery life and more comprehensive controls.

Sony WH-CH720N Wireless

Both the JBL Live 770NC Wireless and Sony WH-CH720N Wireless occupy the midway point between budget and flagship headphones, sharing many of the same features. The JBL are slightly better built and slightly more comfortable. Their controls are more expansive and isolate more noise. Their battery lasts longer, too. The Sony headphones have a somewhat better mic system. Their sound profile is more neutral than the excited sound profile of the JBL. You can EQ both pairs in either option's very capable companion app.

JBL Live 670NC Wireless

The JBL Live 670NC Wireless and JBL Live 770NC Wireless are from the same generation with more in common than not. They share the same app, nearly identical controls, and almost the same frame. The Live 670NC Wireless boast a longer battery life. Because they're on-ears, their noise isolation isn't quite as good as the Live 770NC over-ears' noise isolation. However, the on-ears deliver a bit more consistent sound. Meanwhile, the Live 770NC are more stable fitting and cut out more environmental noise overall.

The JBL Live 770NC are over-ear wireless headphones, and they look quite a bit like the JBL Live 670NC Wireless on-ears, just with larger ear cups. They're plastic with tonal metallic accents on either side of the headband and metallic circles with large logos on the outside of each ear cup—pretty standard for the brand these days. Their padded headband is covered with a somewhat coarse tweed fabric that's color-matched to compliment the plastic. Over-ears tend to be bulky, but the taper of the two-piece ear cup housing cuts down on their overall visual presence. The ear pads are thick, and on the ‘White' colorway, they give the impression of cushy marshmallows. Other colors available include the stealthy 'Black,' 'Blue,' which is aesthetically busier with contrasting navy and silver, and 'Sandstone,' which adds some flash with rose gold accents.

The JBL Live 770NC are comfortable. They're reasonably light and don't clamp down too hard. Their ear cups have a good range of motion to fit a variety of head shapes, and the headband has adequate padding. If you've got a shaved head or are bald, the fabric covering the headband can feel a bit rough. The ear pads aren't removable, and the actual stuffing is a bit stiff, which can impact your ability to get a good seal over your ears. Still, the pads feel slightly softer than the JBL Live 670NC Wireless' ear pads.

Folks with large ears might find there's not enough room for the pads to encircle your ears fully. At the same time, the space between your ears and the drivers offers a good distance, so your ears probably won't press against the drivers.

Additional Controls Voice Assistant + Multifunction + Bluetooth

The JBL Live 770NC have impressive controls. They use a combination of touch controls and physical buttons to cover most commands. There's even a hands-free smart assistant you can configure to Google Assistant (the default) or Amazon Alexa. The buttons feel distinct from each other, so you won't accidentally misfire a command. Their touch-sensitive surface is only on the right ear cup, which you can't alter—sorry, lefties. You can access virtually all the controls without opening the app, which is great.

The headphones chime, indicating they've registered commands on the touchpad, but not when you use the buttons. All of the chimes sound the same, and when you hit maximum volume, the chime is drowned out by your audio. Each step of the Bluetooth pairing process and cycling through listening modes (ANC and Ambient Aware) emit unique accompanying voice prompts.

The JBL Live 770NC are acceptably portable. After all, they're wireless over-ears, so they're only going to be so compact. The headphones' articulating hinges bend the arms inwards to reduce their footprint, and the ear cups can rotate to lay flat. You can sling them around your neck or slide them into their carrying pouch to take them on the go.

The JBL Live 770NC's cloth pouch is passable. It's virtually identical to the JBL Live 670NC Wireless' pouch—a basic, grey, soft fabric with a drawstring. Annoyingly, the drawstring can reopen on its own by simply jostling around your backpack. Nevertheless, the fabric protects your cans from surface scuffs and scratches, even if it won't mitigate the impact of accidental drops.

Design
Build Quality

The build quality of these over-ears is good overall. Their hinges seem reliable, and the ear pads feel nice, not too soft or overly firm, and covered by good quality faux leather. You can't swap the ear pads, which isn't ideal for long-term durability. When adjusting their fit, their metal yokes click reassuringly. The included braided TRS audio cable feels nice; it's not so stiff as to stress the internal wiring, and of course, you can easily replace it without needing to buy new headphones. However, the USB charging cable is very short, which can lead to placing the headphones in awkward locations during a recharge, which isn't ideal for the port. Their overall frame seems fine but a bit creaky, and their plastic doesn't feel very dense, so don't drop them.

7.5
Design
Stability

The JBL Live 770NC's stability is good. They can easily accompany you on a walk and a light jog, but anything too dynamic risks them falling off—that's pretty normal for over-ears. Depending on how well they fit you, you can do some isometric exercises like weightlifting. Since they're wireless, you won't need to worry about catching the audio cable unless you've connected them to a device like an old Apple iPod Shuffle.

The JBL Live 770NC have a very bass-heavy tuning with a fairly excited treble response when used over Bluetooth with ANC on and without modifying the EQ. Hip-hop and EDM fans might enjoy the boomy (arguably bloated) sound of punchy kick drums and the deep rumble of sub-bass synths. The low-end's exaggeration chiefly overwhelms the mid-range, so melodic parts, like lead synths, are comparatively harder to make out and sit low in the mix. You'll hear excited focus on vocals and a bit of harshness on the high registers of guitar solos, while cymbals can sound piercing and shrill. The headphones sound virtually identical over Bluetooth as when they're active and wired, but when wired and powered off, their bass is considerably reduced to a more neutral setting, and the low-treble is also more relaxed; take a look at this comparison.

If that's not your preferred tuning, their companion app is equipped with an equalizer, and when it's set to flat, the sound is the same as the default tuning. You can check out the EQ presets' frequency responses, which are roughly variations on the theme of oodles of bass, except for the 'Vocal' preset, which has a more conservative bass curve. You can also create your own custom EQ.

A comparison of the default sound profile in Ambient Aware, with ANC off and ANC enabled, (shown here) reveals that Ambient Aware adds a bit more low-mid and bass content.

Lastly, if you're using the microphone, the headphones' frequency response changes, as you can see here. This mode emphasizes the frequencies speech occupies in the midrange but can leave audio sounding hollow and thin.

Frequency Response Consistency
Avg. Std. Deviation

The JBL Live 770NC have disappointing frequency response consistency. These over-ear's ability to deliver predictable sound is derailed by factors like thick hair and glasses, which result in a drop in bass by breaking their ear pads' seal around your ears. It's normal to see slight deviations in the bass and treble regions with most headphones, but the observed variations in the midrange are indicative of how tricky it is to achieve consistent-sounding audio between wears. You'll want to take care when placing these on that they sit and distribute clamping force evenly.

The JBL Live 770NC's bass accuracy is sub-par. If you love exaggerated low-end, for EDM or dubstep, for instance, this voicing supplies that. The whole range is exaggerated, especially the high and mid-bass compared to the low-bass frequencies, so it sounds more boomy than rumbly. Kick drums and basslines sound bloated and boomy compared to the (sizeable dose of) thump and rumble of sub-bass synths. As a result, the bassline and subtle low synth pads in tracks like Wildfires by SAULT overwhelm the sparse piano and spring reverb-soaked handclaps.

The mid accuracy of the JBL Live 770NC is excellent. It's fairly even throughout the range and boosted primarily in the high mids, which adds a bit of clarity and intensity to vocals and the harmonics of instruments that otherwise compete with the strong bass emphasis. However, the accuracy of the mids isn't very obvious in the context of the rest of the sound profile, with the large dose of bass emphasis obscuring this somewhat.

The JBL Live 770NC's treble accuracy is decent. Most of the region is exaggerated, besides a notched dip where the low-treble transitions into the mid-treble. As a result, vocals and guitar solos sound articulate and present but also uneven and somewhat harsh. Sibilant details (S and T sounds) in vocals and cymbals come across as piercing, which can cause premature fatigue.

The JBL Live 770NC's peaks and dips performance is passable. As expected from both a bass-rich and trebly sound profile, this frequency response has numerous hills and valleys, indicating that the headphones do a mediocre job controlling their sound. A tall and wide peak occupies most of the bass region with a steep drop just before the mids; this significantly boosts the punch and boom of the bass, with a bit less emphasis on deep rumble. There's a wide dip in the low mids to the center of the midrange, which weakens instruments like rhythm guitars. There's also a sharp peak in the high-mids that ducks back down, and the relatively narrow peak adds clarity and a bit of uneven harshness. The treble range sees several narrow peaks and dips, causing an overall shrill and piercing voicing that exaggerates harmonics unevenly.

Their imaging performance is very good overall. Most headphones by the brand we've tested, with a handful of exceptions, have similar imaging results, suggesting the manufacturer has a good handle on quality control and ergonomics. Imaging varies between units, so these results are only valid for our unit.

The weighted group delay lands below the threshold of audibility, yielding tight bass and transparent treble reproduction. There are slight amplitude and weighted frequency mismatches; however, these also land within good values, and they don't significantly impact the sound.

Our unit exhibits phase mismatch, which is present throughout the treble region, but the very high-frequency peaks aren't super noticeable with real-world content. However, the phase mismatch is more obviously audible in the high-bass and low-mids, particularly with music that has a lot of prominent bass and mid-range instruments in the mix. The right driver sounds audibly boomier than the left driver. On the bright side, their companion app features a channel balance slider that can help mitigate this imbalance.

The JBL Live 770NC have a bad passive soundstage. Their soundstage isn't open or spacious, which is par for the course with closed-back headphones. Audio playback doesn't interact with your listening environment as with open-back headphones, so your audio sounds like it's coming from inside your head. They also don't meaningfully interact with your outer ear to create a sense of direction and immersion.

The JBL Live 770NC include a spatial audio feature in their companion app. You get three preset digital signal processor (DSP) settings: 'Movie,' 'Music,' and 'Game.' These apply the DSP to whatever audio you're listening to. Unlike the Sony 360 Reality Audio on the Sony WH-1000XM5 Wireless, you can use it with any audio source as a novel and immersive way to experience music and movies. However, it's somewhat limited in comparison to what you'll experience with the Sony WH-1000XM5 Wireless' virtual surround sound because the JBL lack analysis of your ears, and unlike Apple Spatial Audio found on the Apple AirPods Max Wireless, the JBL lack head tracking to help create even greater immersion.

The JBL Live 770NC exhibit very good weighted harmonic distortion performance. At normal listening volumes, their distortion is difficult to hear. You won't hear it drastically impact the purity of your audio because the harmonic distortion falls within good limits. There are sections of distortion, like at the transition from the bass to mids and in the low treble, but these aren't too bad.

Their full-range noise isolation is good. The ANC-equipped headphones reduce the deep rumbles of bus engines, although not as effectively as they filter out midrange noise like the ambient of an office. Assuming you achieve an unbroken over-ear seal, their passive isolation blocks a solid amount of high-pitched noise pretty evenly.

While the results appear to indicate that the headphones amplify noise in the bass frequencies, this is strictly limited to the testing rig and the headphones and isn't the case with real-world usage. If you're wearing the headphones, you won't hear environmental noises as being louder than if you remove them.

Their noise isolation performs decently in common scenarios. The combined ANC and passive isolation cuts out environmental sounds fairly similarly. With that said, their noise isolation seems to have the most noticeable impact on typical office noises. They don't perform quite as well with airplane cabin noise, either. Given that much airplane cabin noise resides in somewhat lower frequencies, which the ANC system doesn't attenuate quite so effectively, you'll still hear more of the din than you otherwise would with headphones like the Anker Soundcore Space Q45 Wireless. Still, they're by no means poor performers.

ANC Wind Noise

The JBL 770NC don't have a wind mode that specifically mitigates the anti-noise produced as an overcorrection when wind interacts with exterior ANC mics. That said, the ANC doesn't struggle to deal with wind noise. A gust can negatively impact their ANC's effectiveness and produce the unpleasant whoosh of anti-noise. Still, on the whole, their design manages it well, considering there's no wind reduction mode.

As expected, different listening modes like Ambient Aware and basic ANC Off behave differently when faced with wind, which you can see here to compare.

Their leakage performance is good. Most of the audio range that escapes the headphones isn't audible except in very quiet spaces. What does escape that's audible in busier spaces like offices is a rather trebly band of audio, mainly bright percussion and vocal harmonics. How loudly you listen to your music and the space you're in influence how much of your audio people nearby can hear. While the headphones' companion app includes a leakage compensation function, in testing, it effectively made no difference (you can see the comparison with the leakage compensation on and off here).

Their mic's noise handling is mediocre. In environments with consistent background noise, the headphones manage to mostly prioritize your speech, but distortion remains present. If there are chatty people in the environment, the microphone system also picks them up. The mics struggle with sudden and loud sounds like trains and obscure the intelligibility of your voice.

The JBL Live 770NC have superb battery performance. The manufacturer advertises they'll reach 50 hours of battery life with the ANC on (and 65 hours with it off); our tests yielded 55 hours with ANC enabled. That's more than enough to get through several workdays, a flight or two, and a few commutes without reaching for the USB-C charging cable. According to the manufacturer, if you get caught with a drained battery, a quick five minutes of charging gives you four hours of playback. In addition to the long battery life, you can enable the auto-off timer via the app (30-minute, one-hour, or two-hour settings), so you don't drain the battery overnight if you fall asleep while wearing the headphones.

The companion app for the JBL Live 770NC is great. The JBL Headphones app is shared by many of its models and comes with a pretty robust set of features to control listening modes (ANC, Ambient Aware), tools to shape their sound like parametric EQ and presets, and more, which you can view here.

Spatial audio applies one of three DSP modes to your media to simulate a surround sound experience, but without head-tracking or any analysis of your ears. There's Personi-Fi: essentially a custom EQ combining your unique hearing with what the manufacturer thinks is the best way to hear the sound profile. Low Volume Dynamic EQ adjusts the EQ so that at quieter settings, you can hear the sound curve in a more pleasing way that accounts for how our ears perceive sound at low levels. You also get an adjustable sidetone, latency modes, a decibel limiter to protect your hearing, left/right driver channel balance, and you can set up your voice assistant for hands-free use (with Amazon Alexa or Google Assistant).

The JBL Live 770NC let you use noise cancelling when plugged in with their 1/8" TRS cable and powered on. However, you won't have access to their app when you use them with their analog cable. You can also use them passively, but as expected, this means you don't get ANC.

The JBL Live 770NC have great Bluetooth connectivity. They can connect with two devices simultaneously, so you can easily switch between your work computer and phone when you go for lunch. Although they lack high resolution and adaptive Bluetooth codecs like the aptX suite or LDAC, they have optimized listening modes that are selectable through the JBL Headphones app. These modes include 'Normal,' 'Audio,' and 'Video,' with the latter somewhat reducing the latency to accommodate lipsync issues. It does a bit, but you'll likely still notice some latency. Other factors can influence latency as well, so your experience may vary. 'Audio' mode yields lower latency, while 'Normal' mode yields the greatest latency, but that's not typically a concern if you listen to music or podcasts only. While the manufacturer advertises these headphones as having Bluetooth LE Audio, the manufacturer hasn't yet rolled out the feature in an update as of our testing date.

The JBL Live 770NC can deliver audio via their 1/8" TRS audio cable, but they won't transmit any sound via the mics. You can connect them over Bluetooth if you want to use their microphone system. However, you'll experience latency, and their sound profile changes when the microphone is active. In other words, they're not a substitute for a proper headset, but you can use them for solo gaming, the occasional meeting, and music just fine.
