The JBL Live 670NC Wireless are wallet-friendly on-ear headphones equipped with active noise cancelling (ANC) technology. They come with some useful features that belie their relatively affordable price point, like an impressive 65 hours of advertised battery life with the ANC off (and even more when we tested it). There's also voice assistant integration and a spatial audio feature that's accessible via the companion app.

Our Verdict

5.6 Neutral Sound

The JBL 670NC have a sub-par neutral sound performance. They're hampered by an overexaggerated, bloated bass response that tends to dominate the mix. While the mid and treble ranges are also excited, they don't necessarily compensate for this, although the elevated mid-treble introduces some harshness for sibilants. You can always fine-tune the sound via the companion app, though, to tailor it to your liking. Their passive soundstage performance is disappointing, too, and doesn't offer much when it comes to creating an immersive audio experience. They do have a spatial audio feature available via the companion app, though, which can help compensate for this. On the upside, they deliver audio consistently, so you'll experience similar audio delivery between different listening sessions.

Pros
  • Parametric EQ and presets via the app.
  • Outstanding 88-hour battery life.
Cons
  • The overpowering bass response won't be for everyone.
  • ANC struggles to isolate your audio from noisy environments.
  • Poor passive soundstage.
7.0 Commute/Travel

The JBL 670NC are decent for commute and travel use. They're reasonably comfortable and feature an outstanding 88 hours of continuous battery life, so they'll last for even the longest journeys. That said, they're not the most portable, despite the fact that you can fold up their ear cups. While their ANC does help block out some ambient sound, it's not a huge improvement on the passive isolation provided by their on-ear design. Sounds like engine rumble and street noise will still find their way into your audio.

Pros
  • Outstanding 88-hour battery life.
  • Comprehensive control scheme.
Cons
  • The overpowering bass response won't be for everyone.
  • ANC struggles to isolate your audio from noisy environments.
6.9 Sports/Fitness

The JBL 670NC are okay for sports and fitness use. They have a comprehensive control system and voice assistant integration, which can be great for performing functions while on a run. They have a solid, reasonably sturdy build quality, too, and we tested an outstanding 88 hours of battery life with the ANC on. Sadly, their on-ear design and slippery ear pad material mean they're not the most stable headphones, and they're not super portable, either.

Pros
  • Outstanding 88-hour battery life.
  • Comprehensive control scheme.
Cons
  • The overpowering bass response won't be for everyone.
  • ANC struggles to isolate your audio from noisy environments.
6.6 Office

The JBL 670NC are alright for office use. They have an extremely long 88-hour battery life that'll get you through the workweek with battery to spare, plus they're comfortable enough to wear for extended periods. While they do leak a bit of audio, it's unlikely to disturb anyone unless you're in a very quiet office environment. While they are equipped with ANC technology, it doesn't do much to block out common sounds you'd hear in an office environment, so they're not a great choice for distraction-free productivity.

Pros
  • Parametric EQ and presets via the app.
  • Outstanding 88-hour battery life.
Cons
  • The overpowering bass response won't be for everyone.
  • ANC struggles to isolate your audio from noisy environments.
5.3 Wireless Gaming

The JBL 670NC aren't suitable for wireless gaming. While they're equipped with Bluetooth, even with the lowest latency mode enabled, latency is too high for most games when using the default SBC codec.

6.8 Wired Gaming

The JBL Live 670NC are okay for wired gaming. They can be used via an analog connection, and they come with a 1/8" TRS cable for this purpose. Latency is minimal via this connection type, so you won't experience much lag between your audio and visuals. They're also comfortable enough for long gaming sessions. While their overemphasized bass response will certainly add some boom to in-game audio cues, like explosions, it muddies the rest of the frequency range. Their passive soundstage performance is also poor, so it's tough to pinpoint where environmental audio comes from within the stereo field. Finally, it's worth noting that you won't be able to use the microphone if you're using these headphones wired.

Pros
  • Parametric EQ and presets via the app.
  • Outstanding 88-hour battery life.
Cons
  • The overpowering bass response won't be for everyone.
  • Poor passive soundstage.
5.9 Phone Calls

The JBL Live 670NC are sub-par for phone calls. The integrated mic's recording quality isn't the best, so your voice sounds thin and muffled to whoever's on the other end. The mic's voice handling is also disappointing and can introduce some serious distortion into your audio signal if you're taking a call in a louder environment. Furthermore, the ANC performance is lackluster and won't do much to isolate your call audio from external sounds. On the upside, they're comfortable enough for extended calls, and their 88 hours of continuous battery life means you're unlikely to run out of juice mid-call.

Pros
  • Outstanding 88-hour battery life.
Cons
  • The overpowering bass response won't be for everyone.
  • Disappointing mic recording quality.
  • ANC struggles to isolate your audio from noisy environments.

Differences Between Sizes And Variants

The JBL Live 670NC are available in four color variants: 'Black,' 'White,' 'Blue,' and 'Sandstone.' We tested the 'Blue' variant, but we expect the other colorways to perform similarly. 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 670NC are a pair of on-ear headphones within JBL's 'Live' line of mid-range headphones. They follow in the footsteps of the JBL Live 460NC Wireless, which share a similar build quality and on-ear design. While the two have a similar noise isolation performance, the JBL Live 460NC have an accurate sound profile that follows our target curve much more closely. That said, the older generation lacks the newer model's amazing 88-hour battery life. The Live 670NC's overpowering bass response brings it more in line with DJ headphones, like the Pioneer DJ HDJ-CUE1BT Wireless, where the prominent bass can be an ally when beat-matching.

If you're looking for more headphone options, check out our recommendations for the best on-ear headphones, the best wireless Bluetooth headphones, and the best headphones.

JBL Live 660NC Wireless

The JBL Live 660NC Wireless and the JBL Live 670NC Wireless have different designs. The former is an over-ear design, while the latter has an on-ear design that sits directly on your ear. That said, their distinctions go beyond simple design differences. While both headphones have a boosted bass response, the Live 670NC have an overwhelming amount of bass that can muddy the rest of the mix. By contrast, the Live 660NC follow our target curve more closely, with a balanced sound that leans towards being bass-heavy. The Live 660NC have a better performing ANC system and better mic recording quality, making them a better fit for calls, but they lack the Live 670NC's monumental 88-hour battery life. 

Beats Solo3 2019 Wireless

The Beats Solo3 2019 Wireless and the JBL Live 670NC Wireless are both wireless on-ears, though the JBL feature ANC technology, which makes them a better fit for long commutes and journeys. Both headphones are similarly comfortable, portable, and well-built, though the JBL have a more comprehensive control scheme. When it comes to sound, both headphones pack a serious punch in the low-end, though the JBL have an especially boosted bass response. The Beats have a more balanced sound overall, though. While the JBL's ANC system doesn't do too much to block out background noise, the JBLs noise isolation performance is still a step up from the Beats for isolating you against engine rumble and background chit-chat. The JBLs also feature Bluetooth multi-point connectivity, so you can pair with two devices at once. That said, the Beats feature a W1 chip that allows you to pair seamlessly with Apple devices. 

JBL Live 460NC Wireless

The JBL Live 670NC Wireless and the JBL Live 460NC Wireless both share an on-ear design. They're both equipped with ANC systems, too. While neither will fully insulate you from the roar of a bus engine or the cacophony of a busy street, the Live 460NC do a slightly better job of isolating you. When it comes to sound profile, the Live 460NC have a much more balanced default sound profile, lacking the overpowering bass response of the Live 670NC. The Live 460NC have a better mic recording quality, too, making them a better fit for phone calls, but their battery life falls short of the outstanding 88 hours offered by the Live 670NC

JBL Tune 660NC Wireless

The JBL Tune 660NC Wireless and the JBL Live 670NC Wireless are both on-ear headphones, though the Tune have a retail price that's a little over half that of the Live. Despite their lower price tag, the Tune are superior in a surprising number of aspects: they have a more balanced sound profile with a prominent bass that's not as bloated and overwhelming as the Live's. They also have a better mic recording quality and better mic noise handling. That said, the Live have a slightly better performing ANC system and a much longer continuous battery life at 88 hours. They're also better-built and more comfortable to wear across extended listening sessions. 

JBL Live 770NC 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.

Beats Solo 4 Wireless

The JBL Live 670NC Wireless offer more customization and extra features than the Beats Solo 4 Wireless. While both on-ears are similarly comfortable and well-built, the JBL have companion app support, including a parametric EQ and presets, and they have ANC. While it does a mediocre job of blocking out background noise, it's still better than the Beats' passive capabilities. They also support multi-device pairing and have a significantly longer continuous playback time. However, the Beats have a more neutral sound profile, which some users may prefer, and can also be used via wired USB.

The JBL Live 670NC have a similar on-ear design to the JBL Live 460NC Wireless. They feature ear pads that match the color of the rest of the headphones for a slick, uniform look. They have plastic ear cups that feature a silver ring with the JBL logo centered inside. The rest of the frame is plastic with a thin tweed-like padding on the headband. They're available in 'Blue,' 'Sandstone,' 'White,' and 'Black.'

These on-ears are reasonably comfortable. They're relatively lightweight and don't put pressure on the top of your hand, plus the headband is padded with a tweed fabric material for extra support. The hinges aren't too stiff either, so it's easy to adjust the fit. That said, the padding that's used on the ear cups is quite bulky and isn't made of the most breathable material.

These headphones have great controls, with a mixture of tactile and physical controls that allow you to adjust a wide range of parameters. The control scheme is designed so you can do everything without turning to the companion app, and the buttons are arranged well enough for this to be possible. All the controls are arranged on the right ear cup, with physical buttons on the lower rim and a tactile control surface on the exterior of the ear cup. Audio feedback is provided when you hit max volume, as well as every time you input a control via the tactile surface. There are also voice prompts for powering the headphones on/off, connecting to a Bluetooth source, or switching between ANC and Ambient Aware (which filters external sounds into your audio via the integrated mic). That said, there's not as much feedback for the physical buttons, and they don't always click to confirm a command has been registered. There's also no feedback to indicate that you've adjusted the volume.

Physical buttons on the right ear cup:

  • Power Slider
    • Slide up: Powers the headphones on/off.
  • '+' button
    • Single press: Raises the volume.
    • Press and hold: Skips track forward.
  • '+' and '-' button

The JBL Live 670NC come with a simple, soft cloth carrying pouch. The material is soft enough that it won't scratch the headphones and also feels reasonably robust. The pouch uses a drawstring to close the opening, but we found that it could open back up very easily after being adjusted.

7.5
Design
Build Quality

The JBL Live 670NC have a good build quality. They're made mostly of plastic, metal yokes, and a thin, tweed-like cloth that pads the headband. The ear cup material is a faux leather that feels nice on the skin. The hinges accommodate a good amount of motion that will suit all head and ear shapes, and there's the right amount of stiffness when adjusting the fit, so they don't feel too loose. The included braided audio cable is also high quality and can be easily coiled for ease of transport. Unfortunately, the ear cups aren't swappable, so you'll need to replace the headphones if they get worn out. The plastic frame also creaks a bit when moved and seems susceptible to breakage if dropped or handled roughly.

6.0
Design
Stability

These headphones have passable stability. They won't completely fall off your head during moderately intense activities, like light headbanging, but they're likely to shift around on your head a bit. The ear cup padding material is also a little more slippery than the JBL Live 460NC Wireless, which contributes to them moving around your head more. Thankfully, their wireless design means you don't need to worry about getting the cable snagged on something unless you're using them wired. If you want a more stable set of headphones by the manufacturer, the JBL Live 770NC Wireless over-ear headphones more reliably stay put.

Sound Profile
Bass Amount
4.04 dB
Treble Amount
-2.31 dB

The JBL Live 670NC have an excited V-shaped sound profile with an almost-overwhelming amount of bass. This staggering bass response can dominate the mix, detracting from the clarity and detail of the mids. The treble range is overemphasized across the entire range, too, resulting in sibilants, like hi-hats, sounding overly sharp and piercing to the ear. Fortunately, the companion app offers a parametric EQ and presets, so you can tame some of these more excessive frequencies. You can see how the presets affect the sound profile here.

It's also worth noting that the sound profile will be altered to varying degrees depending on whether the ANC is on or the mic is enabled. While using the ANC function doesn't alter the sound profile drastically, it does reduce the overall volume by a very small amount. Using the Ambient Aware mode does bring about a more noticeable change in the sound profile, though, with less high-bass and more low-mids. Using the mic creates a large drop-off in treble response and diminished lows, as the Bluetooth bandwidth is also used by the mic signal. You can see the sound profile when using a wired connection here.

These on-ears have great frequency response consistency. There's quite a bit more deviation in the response with the left ear, so users who have larger heads or wear glasses will experience some deviation in the bass delivery. There are some inconsistencies in both ears when it comes to the treble range, too, but this is mostly concentrated in a range that we lose sensitivity to over time.

The bass accuracy is poor. The bass response is massively overemphasized across the entire range, resulting in kicks and basslines that sound overly boomy and bloated. Fans of genres like EDM and hip-hop might find some satisfaction in this, but for other genres that put more emphasis on the mids and highs, this bombastic bass can eclipse elements like vocals and lead instruments. This is evident on tracks like Sade's Cherish the Day, where the subby bassline that comes in halfway through the track proceeds to obscure the rest of the delicately balanced mix.

The mid-accuracy is passable. While the response in the low-mid is overemphasized compared to our target curve, it's hard to tell as the bass response is so overpowering. Fortunately, there's a boosted high-mid response that can help bring out the upper harmonics of vocals and lead instruments and can help them cut through the bass frequencies a little.

These headphones have a mediocre treble response. The treble is overemphasized across the entire range, which can help add some much-needed detail to vocals and lead instruments. Unfortunately, the boosted mid-treble means that sibilants, like S and T sounds, are rendered harshly and can sound sharp to the ear.

The JBL Live 670NC have a passable peaks and dips performance, meaning they don't always control their own sound profile. There's a peak in the mid-bass that adds extra boom to kicks and basslines, followed by a sharp dip in the low- and mid-mid that can make vocals and lead instruments sound less present in the mix. There's a significant peak in the high-mid that adds clarity and presence to the upper harmonics of vocals. Finally, there's a sharp peak in the mid-treble that brings out the harshness in sibilants and adds a piercing quality.

The JBL Live 670NC have an excellent imaging performance. Most of the JBL headphones we've tested have had solid imaging, which is indicative of the brand's dedication to quality control and ergonomics. Weighted group delay falls below the audibility threshold across the entire range. While there is some amplitude mismatch in the high treble range, this isn't audible, as we lose sensitivity to this range over time. Otherwise, our unit is well-matched in terms of frequency and phase response. Imaging tends to vary between units, though, so users who experience an amplitude mismatch with their headphones can also use the L/R balance feature in the companion app to try and correct this.

These headphones have a passable full-range noise isolation performance. Their ANC system struggles to block out bass-range noise but does a slightly better job of cutting out mid-range frequencies, like background chatter. They block a decent amount of treble-range noise; however, this is mostly due to the passive isolation provided by their on-ear fit. Typically, choosing an over-ear fit, such as the JBL Live 770NC Wireless, supplies better noise isolation performance. It's worth noting that although our results indicate that the ANC actually amplifies the low-bass frequencies, it is due to an issue with our testing apparatus rather than the headphones themselves. Subjectively, low-bass frequencies seem equally audible, regardless of whether the ANC is off or on.

Wind noise is challenging for headphones to tackle as it interferes with the ANC's microphones. This causes the ANC to produce anti-noise to cancel it out, even though the sound doesn't really reach your ear. However, it results in a loud, irritating sound. These headphones don't have a wind-handling feature that would help to mitigate this.

The JBL Live 670NC's microphone has a sub-par noise-handling performance. In moderately noisy environments, like a busy street, your voice will become quite distorted as the mic struggles to adapt to its background. This issue is exacerbated in noisier environments, like a subway car, as the mic can take a long time to adjust to this louder noise, and your voice sounds impossible to understand in the meantime.

There's even an auto-off timer feature that can help preserve battery life, although this has to be enabled via the app first. Finally, the manufacturer advertises a quick charge feature that gives you four hours of playtime from just a five-minute charge. However, it should be noted that battery life tends to vary according to use, so your experience may differ.

The JBL Live 670NC Wireless come with a 1/8" TRS cable for analog connection. When connected this way, these headphones can switch between passive mode and active mode, the latter of which disables Bluetooth (and app access) and enables active features like ANC.

These headphones have great Bluetooth connectivity. They support multi-device pairing with up to two devices, so you can stay connected to your phone and your laptop. They support Google Fast Pair, too, for seamless pairing with your Android device. Sadly, they're incompatible with any high-resolution streaming codecs, like LDAC or aptX HD. Latency via the default SBC codec is great in 'Audio' mode, though, so you likely won't experience any lip-sync issues when using these headphones to watch video content. You can even switch between different latency presets like 'Video' and 'Normal,' but we found the 'Audio' mode to have the lowest latency performance. However, some apps and devices seem to compensate for latency differently, so your results may vary.

These headphones are partially compatible with PCs, so you'll only be able to receive audio when using a wired connection. You can always switch to a Bluetooth connection for full mic and audio compatibility, but bear in mind that this will introduce some latency.
