The JBL Tune 660NC Wireless are fairly versatile on-ear headphones with a long continuous battery life of roughly 42 hours. They have a slightly v-shaped sound profile that adds punch and a bit of brightness to your mixes, making them suitable for a variety of audio content. However, although they have an active noise cancelling (ANC) feature, it does a sub-par job of blocking out background noise. They also feel a bit flimsy and don't have any sound customization features, but you can connect them to two devices at once via Bluetooth or use them wired with the included audio cable.

Our Verdict

6.8 Mixed Usage

The JBL Tune 660NC are alright for mixed use. They have long continuous battery life and a slightly v-shaped sound profile that should be suitable for lots of content and genres, although they lack sound customization features. They support multi-device pairing via Bluetooth, so you can easily switch between your phone and computer without re-pairing. They also come with a 1/8" TRS to TRRS cable that allows you to use them wired, but you can only receive audio. Unfortunately, their ANC feature doesn't isolate you from very much noise. They aren't very well-built or stable, either, so they aren't ideal for workouts.

Pros
  • Very good battery performance.
  • Support multi-device pairing.
Cons
  • Disappointing ANC performance.
  • No sound customization features.
7.3 Neutral Sound

The JB Tune 660NC are decent for neutral sound. They deliver sound quite consistently and have a slightly v-shaped sound profile, which adds a bit of extra rumble, punch, and brightness. They should be suitable for a variety of genres, though. However, some listeners may find sibilant sounds like cymbals are slightly piercing or harsh. Their soundstage doesn't seem very open or spacious either, which is typical for closed-back headphones. Unfortunately, they also lack any sound customization features.

Pros
  • Decently consistent sound delivery.
Cons
  • No sound customization features.
7.0 Commute/Travel

The JBL Tune 660NC are satisfactory for commuting and traveling. They have an ANC feature, but it does a poor job of isolating you from noise, especially bass-range sounds like rumbling bus and plane engines. Their roughly 42-hour battery life should be long enough for long trips, though, and they have easy-to-use controls. Unfortunately, they don't have the most comfortable fit and don't come with a carrying case or pouch.

Pros
  • Very good battery performance.
  • Convenient onboard controls.
Cons
  • Disappointing ANC performance.
  • No carrying case or pouch included.
6.9 Sports/Fitness

The JBL Tune 660NC are okay for sports and fitness. Like a lot of on-ear headphones, they aren't very portable. They also do a poor job of staying in place when you move around, so they aren't very well-suited for more intense workouts. On the plus side, they shouldn't make your ears feel too hot and have easy-to-use controls on one ear cup, so you can adjust your music's volume or skip a song without taking out your phone.

Pros
  • Convenient onboard controls.
  • Good breathability.
Cons
  • Mediocre build quality.
  • No IP rating for water resistance.
6.8 Office

The JBL Tune 660NC Wireless are alright for office use. Their ANC feature does a sub-par job of blocking out background noise, and they aren't very comfortable. However, they have a long continuous battery life of roughly 42 hours and don't leak very much audio, so you should be able to listen to your music at fairly high volumes without bothering people nearby. You can pair them with more than one device at once, so you can easily switch between listening to audio on your phone and computer.

Pros
  • Support multi-device pairing.
  • Don't leak too much sound.
Cons
  • Disappointing ANC performance.
  • May not be comfortable for long sessions.
5.4 Wireless Gaming

The JBL Tune 660NC are Bluetooth headphones that you can't use wirelessly with PlayStation or Xbox consoles. They're compatible with Bluetooth-enabled PCs, but their latency is likely too high to be suitable for wireless gaming.

7.0 Wired Gaming

The JBL Tune 660 are decent for wired gaming. You can plug them into a Playstation or Xbox controller with the included 1/8" TRS to TRRS cable to receive audio, but you can't use the integrated microphone. Their sound profile helps emphasize sound effects in action-packed games, but unfortunately, they aren't very comfortable, so they may not be ideal for long gaming sessions.

Pros
  • 1/8" TRS to TRRS audio cable included.
Cons
  • May not be comfortable for long sessions.
6.7 Phone Calls

The JBL Tune 660NC are alright for making phone calls. The integrated mic makes your voice sound thin, but it's still clear and easy to understand. They support multi-device pairing and have easy-to-use buttons on one earcup that allow you to answer, end, and decline calls without pulling out your phone. Unfortunately, the ANC system doesn't block out very much ambient sound, and the mic struggles to separate your voice from background noise, so these headphones aren't ideal for taking calls in a loud environment like a subway station.

Pros
  • Convenient onboard controls.
  • Decent mic recording quality.
Cons
  • Disappointing ANC performance.
  • Mic has mediocre noise handling.
  • 6.8 Mixed Usage
  • 7.3 Neutral Sound
  • 7.0 Commute/Travel

Test Results

Design
Design
Style

The JBL Tune 660NC Wireless are on-ear headphones with a simple, quite nondescript appearance. They have a narrow plastic headband and the manufacturer's logo stamped onto each small round ear cup. They're available in a few different colors, including 'Black', which is the variant we tested, as well as 'Blue', 'White', or 'Pink'.

The JBL Tune 660NC Wireless are fairly comfortable. They're light and don't put too much pressure on your head. The ear cups' hinges have a good range of motion. Unfortunately, the headband only has a small amount of padding in the middle, which may make them a little less comfortable if you're wearing them for long periods.

Additional Controls Voice Assistant

The JBL Tune 660NC headphones have good controls. The buttons are all found on the right ear cup and are easy to distinguish from each other. There are volume up and down buttons that you can also press and hold to skip tracks forward and backward, respectively. The middle button allows you to play/pause music as well as answer and end calls. You can also hold it down to decline a call or double-tap to activate your phone's voice assistant. There's a power button, as well as an ANC button. Pressing it once turns active noise cancelling on or off, or mutes and unmutes your mic during a phone call. The buttons are clicky, and you hear audio cues when you reach maximum or minimum volume and when you pair the headphones with a device via Bluetooth.

Breathability

The JBL Tune 660NC have good breathability. Their on-ear design means they don't completely cover your ears, which should allow for more airflow than most over-ear headphones. While they do trap a bit of heat, you shouldn't sweat more while wearing them.

Build Quality

The JBL Tune 660NC Wireless have an unremarkable build quality. They're made of cheap-feeling plastic, and the faux leather padding on the headband isn't very comfortable. While the ear cups have a good range of motion, the headphones' yokes and hinges don't feel particularly solid. They lack an IP rating for dust and water resistance, although we don't currently test for it.

5.5
Design
Stability

The JBL Tune 660NC Wireless aren't very stable. Like the JBL Tune 510BT Wireless, they aren't well-suited for use during a workout or any other activity where your head moves around a lot since they can easily fall out of place, even with low-intensity head movements.

The JBL Tune 660NC Wireless have a slightly v-shaped sound profile. It lends mixes some extra rumble and punch, while vocals and lead instruments sound present and clear. There's some overemphasis in the mid-treble range that adds extra brightness, but it may make sibilants like S and T sounds and cymbals seem piercing or harsh for some. Unfortunately, they don't have an EQ or presets to help customize their sound profile.

The JBL Tune 660NC Wireless have decent frequency response consistency. Their bass delivery is fairly consistent, but you may experience a drop in bass if you wear glasses or have thick hair. There's also some inconsistency in the mid and treble ranges depending on the headphones' fit and positioning, so you may need to take the time to adjust them each time you wear them to get a consistent sound.

The JBL Tune 660NC have good bass accuracy. The low and mid-bass ranges are overemphasized, which adds thump, rumble, and punch to your music. There's also some extra high-bass, which adds warmth but also a bit of boominess.

The JBL Tune 660NC Wireless have amazing mid accuracy. The range is quite even and well-balanced, so vocals and lead instruments sound clear, present, and accurate. That said, the slight overemphasis between the mid-mid and high-mids also makes these same sounds a bit more forward and intense.

The JBL Tune 660NC Wireless have decent treble accuracy. The low-treble is very well-balanced, so vocals and lead instruments sound present, detailed, and accurate. The peak in the mid-treble adds brightness, but may also make some sibilants like cymbals or S and T sounds seem harsh and piercing.

The JBL Tune 660NC Wireless have decent peaks and dips performance. A shallow dip across the low-mid range slightly thins out instruments and lead vocals, while a small bump across the mid-mid and high-mid ranges adds a bit of harshness to their sound. There's also a dip in the mid-treble followed by a bigger peak in the same range, making sibilants like S and T sounds seem alternately piercing and dull.

The JBL Tune 660NC have an incredible imaging performance. Their weighted delay is almost entirely below the audibility threshold, except for a very small bump in the bass range which loosens their bass ever so slightly. However, it shouldn't be noticeable overall. Also, the L/R drivers of our unit are very well-matched in terms of amplitude, frequency, and phase response, so objects like voices and footsteps are accurately placed within the stereo image. That said, these results are only valid for our test unit, and yours may perform differently.

The JBL Tune 660NC have a poor passive soundstage.

It's also not very open or spacious, which is typical of closed-back headphones.

The JBL Tune 660NC Wireless have a very good weighted harmonic distortion performance.

The JBL Tune 660NC have a disappointing noise isolation performance. They have an ANC system, but it doesn't isolate you well from bass-range sounds like rumbling bus or plane engines. It does an okay job of blocking out higher-pitched noises, like a background conversation or humming A/C unit.

The JBL Tune 660NC Wireless have a very good battery performance. With their ANC on, they provide just over 42 hours of continuous playback, which should be more than enough for a few days of use. However, they're advertised to last around 55 hours with the ANC off. Also, the manufacturer says you can get two hours of playback from a five-minute 'Quick Charge', but we don't currently test for that. Unfortunately, they don't have any power-saving features like an auto-off timer or standby mode. If you run out of battery life, you can use the headphones passively with the included audio cable. Note that battery performance can vary with real-life use, so you may have a different experience.

The JBL Tune 660NC have great Bluetooth connectivity. You can pair them with up to two devices at once, which allows you to switch from listening to music on your phone to watching a movie on your computer without re-pairing the headphones. An incoming call always takes priority, no matter what device's audio you're listening to, though. These headphones have low latency on iOS, but unfortunately, their latency on PCs and Android devices is somewhat high, which could be an issue if you want to use them to watch videos or play games. That said, some apps and devices seem to compensate for latency, so your real-world experience may vary.

Differences Between Sizes And Variants

The JBL Tune 660NC Wireless headphones come in a few different colors: 'Black,' 'White', 'Blue', and 'Pink'. We tested the 'Black' variant but expect our results to be valid for the others too. You can see the label for the unit we tested here. If you come across another variant or your headphones are different, please let us know in the discussions so we can update our review.

Compared To Other Headphones

The JBL Tune 660NC are Bluetooth on-ear headphones similar to the JBL Tune 510BT Wireless headphones, with an added ANC feature. Unfortunately, it does a sub-par job of isolating you from noise next to other ANC on-ear headphones, like the Beats Solo Pro Wireless.
