JBL TUNE 750BTNC Wireless Headphones Review

The JBL TUNE 750BTNC look very similar to the JBL E55BT Wireless. While we bought the black version, they're also available in blue, white, or coral color variants. The entire headphones are covered in whichever color you purchase, and they look fairly sleek and modern.

The JBL TUNE 750BTNC aren't the most comfortable. Despite being marketed as over-ears, their ear cups are an awkward size that causes them to sit on top of your ears as opposed to around them, making them uncomfortable even during short listening sessions. That being said, people who have very small ears that fit inside the ear cups will likely find them quite comfortable as they're fairly well-padded. If you're looking for more comfortable headphones, consider the JBL Live 460NC Wireless or the JBL Tune 760NC Wireless.

The control scheme of the JBL TUNE 750BTNC is decent. Their physical, clicky buttons are easy to use, and they offer a good amount of functionality, including volume control and voice assistant as well as the standard media/phone controls. All the controls are on the right ear cup, which makes them easy to find, but it might be annoying if you only have your left hand free.

As is to be expected with most over-ear headphones, the JBL TUNE 750BTNC aren't the most portable. On the bright side, they do fold up into a slightly more compact shape to take up less space in a bag or backpack.

The JBL 750BTNC don't come with a carrying case.

The build quality of the JBL TUNE 750BTNC is only mediocre. The entire headphones are made out of plastic, unlike most headphones that at least have a thin piece of metal in the headband. The charging port is also hidden under the yoke of the ear cup, which could potentially be an issue if they get yanked while charging. It also makes it difficult and awkward to reach the port.

The JBL TUNE750BTNC feel decently stable. While they tend to fall off the head during more intense movements, they don't move around much during jogs or light runs.

The sound profile of the JBL TUNE 750BTNC is very accurate and well-balanced. All ranges follow our target curve quite well and while there's a bit of extra bass, it isn't overpowering and provides a good amount of extra punch to music. Overall, they're well-suited to a very wide range of genres and content.

The frequency response consistency of the JBL 750BTNC is good. Unfortunately, due to their awkwardly sized ear cups, different people will likely experience their bass response differently, depending on the quality of the seal they're able to achieve.

The bass accuracy of the JBL TUNE 750BTNC is very good. The entire range is quite even and while it's a little over-emphasized, it isn't boomy or overpowering. Most people will likely enjoy the extra thump and punch that these headphones bring to music.

The mid accuracy of the JBL TUNE 750BTNC is superb. Almost the entire range is perfectly balanced, resulting in an accurate and natural reproduction of instruments and vocals.

The JBL TUNE 750BTNC have very good treble accuracy. The most audible portions of this range are quite even and balanced, including low-treble which is responsible for the detail and presence of almost all instruments and vocals. Mid-treble is a bit more uneven, which may result in some vocals sounding dull and lispy while others might be slightly piercing. High-treble is slightly more uneven, though it's at high enough frequencies that most people won't notice it.

The peaks and dips performance of these headphones is very good. All ranges are quite even, with only minor rises and falls that sound natural and aren't abrupt enough to be noticeable. The most noticeable peak is in mid-treble, which may make some sounds more piercing and harsh compared to the dip right before it that darkens and dulls the sounds in this range.

The imaging performance of these headphones is great. Their GD graph shows that while the treble range is well below the audibility thresholds, resulting in a transparent treble reproduction, the bass response is slightly looser, though it may not be too noticeable to everyone. On the bright side, the L/R drivers of our test unit are very well-matched, which is important for the accurate localization of objects (voices, instruments, video game effects) in the stereo image.

As is expected from closed-back over-ear headphones, the passive soundstage of these headphones is bad. The PRTF response graph shows that they don't activate the resonances of the pinna (outer ear) much, which is one of the big factors in creating a speaker-like soundstage. Therefore, the soundstage is perceived as small and located inside your head.

The JBL 750BTNC don't have any virtual soundstage features.

The weighted harmonic distortion performance of the JBL 750BTNC is decent. Most frequencies fall within good limits at both moderate and high volumes, resulting in fairly clear and pure audio reproduction.

These are the settings used to test the JBL 750BTNC; our results are only valid when using these settings.

The noise isolation performance of these headphones is only okay. Their ANC (active noise cancelling) does almost nothing to help cancel out treble or mid-range sounds and only helps cancel background noise in the bass range. That being said, their ANC doesn't work very well, and they do a bad job at cancelling out the low rumble of bus or plane engines. While the headphones help passively block out background chatter by physically blocking your ears, they're only decent at this, and you'll still hear most lower-frequency voices. On the bright side, they do a good job at blocking higher-pitched sounds, like the hum of a fan or AC unit, though most headphones block these sounds.

The leakage performance of the JBL TUNE 750BTNC is good. Even at moderately high volumes, they fall beneath the noise floor of an average office, so you can listen to your music without bothering coworkers.

The JBL 750BTNC have an integrated microphone. Their included TRRS cable doesn't feature an in-line mic, so even wired, you'll be using the integrated microphone.

The recording quality of the microphone is mediocre, which is fairly average for Bluetooth headphones. When using the mic, your voice sounds natural and easy to understand, though it's slightly thin and lacking in brightness.

The noise handling of the microphone is sub-par. When using the headphones in noisy environments like a subway station, your voice gets easily drowned out by background sounds.

The overall battery performance of the JBL TUNE 750BTNC is decent. They last nearly 17.5 hours off a single charge with the ANC turned on, which is longer than the advertised 15 hours, and they also charge quicker than the advertised two hours. Unfortunately, the micro-USB charging port is located behind the yoke of one of the ear cups, which is difficult and awkward to reach.

These headphones don't have a dedicated companion app.

The Bluetooth connectivity of the JBL TUNE 750BTNC is great. They support multi-device pairing to two different devices, so you can easily switch between your phone and PC. Their PC latency should be low enough for watching movies without any noticeable lag. When watching YouTube videos, we tested low latency on Android devices, though unfortunately, there were noticeable sync issues with iOS. It's worth noting that different apps and devices seem to compensate for latency differently, so your experience may vary.

These headphones don't support any wireless connection other than Bluetooth.

The JBL TUNE 750BTNC come with a 1/8" TRS to 1/8" TRRS cable. However, they can't pass microphone audio, so if you use them wired, you can only hear audio. These headphones also come with a very short micro-USB cable, which is a shame considering the awkward placement of the charging port.

These headphones can connect to PCs via Bluetooth with full audio and mic compatibility. However, although they also come with an audio cable, it's a 1/8" TRS to 1/8" TRRS cable, so you can only receive audio.

The JBL TUNE 750BTNC are only compatible with PlayStation consoles when you plug in their 1/8" TRS to 1/8" TRRS cable into your controller. However, you can only receive audio via this connection.

The JBL TUNE 750BTNC only support audio via analog on Xbox consoles. It's because their 1/8" TRS to 1/8" TRRS cable can't pass through mic audio.

These headphones don't have a base/dock.
