The JBL Tune 660NC Wireless are on-ear Bluetooth headphones. They have an active noise cancelling (ANC) feature to help block out ambient sound and support multi-device pairing, so you can stay connected with two devices simultaneously. You can also use them wired with the included audio cable. However, they don't have a companion app and lack sound customization features.

Our Verdict

7.5 Neutral Sound

The JB Tune 660NC are good for neutral sound. They deliver sound consistently and have a slightly v-shaped sound profile, adding a bit of extra rumble, punch, and brightness. Sibilant sounds like cymbals are slightly piercing and harsh, though. Their soundstage doesn't seem very open or spacious, which is typical for closed-back headphones. Unfortunately, they also lack any sound customization features.

Pros
  • Convenient onboard controls.
  • Good frequency response consistency.
Cons
  • No sound customization features.
6.9 Commute/Travel

The JBL Tune 660NC are fair 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 will 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 won'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.
6.9 Office

The JBL Tune 660NC are alright for office use. Their ANC feature does a sub-par job of blocking background noise, and they aren't the most comfortable. However, they have a long continuous battery life of roughly 42 hours and don't leak very much audio, so you can listen to your music at fairly high volumes without bothering people nearby. You can pair them with multiple devices simultaneously, 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 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 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 cable included.
Cons
  • May not be comfortable for long sessions.
6.6 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.
  • 7.5 Neutral Sound

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 forums 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 but with an added ANC feature. Unfortunately, it does a sub-par job of isolating you from noise compared with other ANC on-ear headphones, like the Beats Solo Pro Wireless and the JBL Live 460NC Wireless.

If you're looking for other options, check out our lists of the best on-ear headphones, the best noise cancelling headphones, and the best wireless Bluetooth headphones.

Sony WH-CH520 Wireless

The JBL Tune 660NC Wireless and Sony WH-CH520 Wireless are on-ear Bluetooth headphones. Of the two, only the JBL have active noise cancelling (ANC), which isn't impressive, but it reduces ambient chatter and traffic noise more effectively than the Sony. They also fold down smaller with more comprehensive controls. Their sound is much more bass-heavy without an app to adjust the EQ. The battery life of the Sony headphones lasts longer. Their sound profile is more balanced with an app for EQ and virtual surround sound. Unfortunately, their passive-only noise isolation only suppresses high-pitched sounds like shrill brakes. However, their headband is better padded and more comfortable to wear.

JBL Live 460NC Wireless

The JBL Live 460NC Wireless are slightly better on-ear headphones than the JBL Tune 660NC Wireless. The Live 460NC are more comfortable and feel better-built.  They have a better performing active noise cancelling (ANC) feature and are compatible with the JBL Headphones app, which allows you to adjust their sound profile using their parametric EQ and presets. However, the Tune 660NC have longer continuous battery life.

JBL Tune 510BT Wireless

The JBL Tune 660NC Wireless are better than the JBL Tune 510BT Wireless for most purposes. They have longer continuous battery life and leak less audio. They also have an ANC feature that blocks out much more ambient noise than the 510BT can passively, but their noise isolation performance is sub-par overall. On the other hand, the 510BT deliver sound more consistently.

JBL TUNE 750BTNC Wireless

The JBL TUNE 750BTNC Wireless are better for most purposes than the JBL Tune 660NC Wireless. The 750BTNC have a much better ANC feature and a somewhat more neutral sound profile, which some listeners may prefer. They also have a more stable fit and a better build quality. On the other hand, the 660NC have longer continuous battery life, and their integrated mic has a significantly better recording quality.

JBL Live 650 BTNC Wireless

The JBL Live 650 BTNC Wireless are better headphones than the JBL Tune 660NC Wireless. The Live 650 BTNC are more comfortable, stable, and work with a companion app that gives you access to a parametric EQ so you can customize how they sound. Their ANC feature has a much better performance and blocks out a good amount of mid-range noise like ambient conversations. On the other hand, the Tune 660NC have longer continuous battery life, and their microphone has a better recording quality.

Beats EP

The JBL Tune 660NC and the Beats EP have different strengths, and which you may prefer depends on your preferences. The JBL are wireless Bluetooth headphones and have better onboard controls. They also do a better job of isolating you from ambient sound, thanks to their ANC, and don't leak as much audio. On the other hand, the Beats are wired headphones and have a slightly more neutral sound profile, which some listeners may prefer. Their mic also has a better recording quality.

Sony WH-XB700 Wireless

The JBL Tune 660NC are better for most purposes than the Sony WH-XB700 Wireless. The JBL have a more neutral sound profile, which some listeners may prefer, a better mic recording quality, and longer continuous battery life. They also have an ANC feature, although it has a disappointing performance. On the other hand, the Sony have a more comfortable, stable fit and a better build quality.

JBL Live 400BT Wireless

The JBL Live 400BT Wireless are better than the JBL Tune 660NC Wireless for most purposes. The Live 400BT have a more stable fit and a better build quality. They also work with a companion app that offers a parametric EQ and presets, so you can customize their sound. The Tune 660NC have onboard controls that offer better feedback and include mic control. They also have longer continuous battery life and an ANC feature, although it doesn't offer much improvement over the headphones' passive noise isolation performance. The Live 400BT do a slightly better job of blocking out mid-range noise like conversations, even without an ANC system.

Build Quality

They 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 aren't rated for dust or water resistance, but that's the norm for on-ear headphones.

Design
Stability

They aren't very stable. Like the JBL Tune 510BT Wireless, they aren't intended for workouts and are likely to fall off your head, even during moderate exercise like a jog in the park.

JBL Tune 660NC have a slightly V-shaped sound profile. It lends mixes some extra rumble and punch. Voices and instruments sound clear and accurate but are slightly veiled by an underemphasis in the low-treble. Sibilants are also bright and somewhat piercing. Unfortunately, they don't have an EQ or presets to help customize their sound profile.

They have good 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 okay treble accuracy. There's some underemphasis in the low treble, so voices in songs like the chorus of Homemade Dynamite by Lorde sound veiled instead of clear. The peak in the mid-treble adds brightness but also makes sibilants like cymbals or S and T sounds seem harsh and piercing.

They have an okay peaks and dips performance. There are peaks and dips across the range, indicating that the headphones struggle somewhat to control their sound profile. A shallow dip in the mid to high-bass adds body and boom, while a dip across the low-treble slightly veils instruments and lead vocals. 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.

They have excellent imaging performance. JBL headphones tend to have well-matched drivers, which results in good imaging and indicates the brand's quality control and ergonomics. Our unit's weighted group 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's not very noticeable overall. Also, the L/R drivers of our unit are well-matched in terms of amplitude, frequency, and phase response, so objects like voices and footsteps are accurately placed within the stereo image. However, imaging varies from unit to unit.

The JBL Tune 660NC have a good weighted harmonic distortion performance. At moderate volumes, there's some distortion in the mid-treble range. A narrow peak also affects a small range of low-bass frequencies in the right driver. However, it's hard for most people to hear with real-life content, and otherwise, all frequencies fall within good limits, resulting in clean and pure audio reproduction.

The JBL Tune 660NC's battery performance is very good. With their ANC on, they last for about 42 hours of continuous use, which is close to the advertised 44-hour battery life with ANC on. The manufacturer also advertises that they last for 55 hours with the ANC off, and they have a five-minute quick-charge feature for two hours of playback. 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. Also, battery performance can vary with real-life use.

They have great Bluetooth connectivity. You can pair them with up to two devices simultaneously, allowing 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. Unfortunately, their latency on PCs and iOS and Android devices is somewhat high, so you're likely to notice some audio lag if you're gaming or watching videos. That said, some apps and devices seem to compensate for latency.
