JBL Tune 660NC Wireless Headphones Review

The JBL Tune 660NC Wireless are fairly adaptable on-ear headphones with a substantial 42-hour continuous battery life. They are appropriate for a range of audio content because of their slightly v-shaped sound profile, which gives your mixes punch and a little amount of brightness. They do have active noise cancellation (ANC) technology, but it does a poor job of isolating background sounds. They are a little flimsy and lack sound customization options, but you can pair them with two devices at once via Bluetooth or use the included audio cable to use them wired.

Differences Between Sizes And Variants

Black, White, Blue, and Pink are some of the available color options for the JBL Tune 660NC Wireless headphones. We only tested the “Black” type, but we believe that our findings hold true for the others as well. Below is the label for the product that we evaluated. Please let us know in the comments if you find another variation or if your headphones are different so we can update our evaluation.

Test Results

On-ear headphones, the JBL Tune 660NC Wireless have a straightforward, unremarkable design. They have a thin plastic headband and each tiny round ear cup is imprinted with the maker’s emblem. They’re available in a few various hues, including ‘Black’, which is the variant we tested, as well as ‘Blue’, ‘White’, or ‘Pink’.


JBL Tune 660NC Wireless Comfort Picture

Comfort The JBL Tune 660NC Wireless are comparatively cozy. They don’t exert a lot of pressure on your head and are lightweight. The hinges on the ear cups can move freely. However, there isn’t much padding in the centre of the headband, which can make them a little less comfortable if you wear them all day.



JBL Tune 660NC Wireless Controls Picture

The controls on the JBL Tune 660NC headphones are good. All of the buttons are located on the right ear cup and are distinct from one another. You can press and hold the volume up and down buttons to move ahead and backward through the tracks, respectively. You may play and pause music as well as answer and finish calls with the middle button. You may also double-tap to activate your phone’s voice assistant or hold it down to reject a call. Both the power button and the ANC button are present. When you press it once, active noise cancellation turns on or off and you may also mute and unmute your microphone while on a 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.


JBL Tune 660NC Wireless Portability Picture

These are quite portable, the JBL Tune 660NC Wireless. The headphones are more manageable and easier to stow or fit into a bag because the ear cups rotate to lay flat. They don’t, however, come with a carrying bag or pouch to keep them safe while you’re out and about.

Build Quality

The build quality of the JBL Tune 660NC Wireless is average. The cushioning on the headband is faux leather, and they are manufactured of cheap-feeling plastic. The yokes and hinges of the headphones feel very flimsy, despite the ear cups’ decent range of motion. Despite the fact that we don’t currently test for it, they don’t have an IP classification for dust and water protection.


Instable are the JBL Tune 660NC Wireless. They can easily slip out of place, even with low-intensity head movements, making them unsuitable for use during a workout or any other activity where your head moves around a lot like the JBL Tune 510BT Wireless.

Sound Profile

The sound profile of the JBL Tune 660NC Wireless is slightly v-shaped. Vocals and lead instruments sound present and audible, giving mixes more rumble and punch. Mid-treble overemphasis gives extra brightness, however some listeners may find sibilants like S and T sounds and cymbals to be piercing or harsh due to this. Sadly, they lack an EQ or presets to aid in modifying their sound profile.

Frequency Response Consistency

The JBL Tune 660NC Wireless feature a respectable consistency in frequency response. Its bass delivery is very steady, however if you wear glasses or have thick hair, you might hear a dip in bass. You may need to take the time to adjust the headphones every time you use them in order to have a consistent sound because there is some variation in the mid and treble frequencies depending on how well the headphones fit and are placed.


The JBL Tune 660NC has outstanding imaging capabilities. Their weighted delay is almost totally below the threshold of audibility, with the exception of a very little bump in the bass register that somewhat loosens their bass. Overall, though, it shouldn’t be visible. Also, the amplitude, frequency, and phase responses of our unit’s L/R drivers are very well matched, allowing for precise placement of stereo objects like footfall and voices. The results are solely applicable to our test unit, thus your device may behave differently.


The latency values of these headphones have been updated to Test Bench 1.5. We previously measured “iOS Latency” at 119 ms and “Android Latency” at 166 ms using Test Bench 1.4. Instead of using a single measurement, our new test bench averages three measurements, which results in a delay of 237 ms on Android and 160 ms on iOS. We have therefore revised our language to more accurately match test bench 1.5 measurements.

The Bluetooth connectivity on the JBL Tune 660NC is excellent. You can couple them with up to two devices simultaneously, making it possible to go between watching a movie on your computer and listening to music on your phone without having to re-pair the headphones. Yet, no matter what device’s audio you’re listening to, an incoming call always takes precedence. Sadly, their latency is relatively high on PCs and iOS and Android devices, which may be a problem if you want to utilize them to watch films or play games. However, certain software and hardware seem to make up for latency, so your actual experience may differ.


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 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.
