JBL Live 780NC Review: Strong ANC, Heavy Bass

The JBL Live 780NC is an over-ear Bluetooth headphone with active noise cancelling that looks fairly conventional at first glance. The shape is modern and, more significantly, the model finally puts the LE Audio standard front and centre, a standard that is expected to appear across the brand's Bluetooth products from now on.

Beyond that headline change, the headphone follows the line established by the previous Live 770NC. It works with the JBL Headphones app, folds for storage and keeps a wired connection, albeit a minimal one.

The Live 780NC arrived in March 2026 in no fewer than seven colours: black, white, sand, green, blue, purple and orange. The sand finish was the version assessed. The measurements below were recorded on firmware version V26.04.10 with version V.5.36.8 of the JBL Headphones app.

It has taken JBL years to arrive at a design that feels genuinely modern and relatively premium. Earlier Live models were serious but still a little rough around the edges, and the flashier JBL Tour One M3 looks plastic-heavy by comparison.

The Live 780NC is an effective redesign. It is an attractive headphone, if not a particularly novel one, combining airy lines with a very solid build. Its styling influences are a little vague: the earcups draw on JBL's own heritage, with a round outer face and an oval inner section; the very slim headband arms, hollowed on the outside, recall B&O designs; and the asymmetric head pad echoes the Sony WH-1000XM6.

Build quality is closer to classic Sony or Bose flagships than to earlier Live models, which is a genuine surprise. JBL uses anodised aluminium arms and excellent imitation-leather earpads, without abandoning its familiar folding structure. To be entirely fair, the headphone does not feel indisputably more robust than the Live 770NC before it. Even so, the sense of matching that build while looking more elegant, less tank-like and entirely free of structural creaking shows how well the work has been done. A carry pouch is included, although it is a basic, entirely soft one.

The one clear omission is a replaceable battery. Setting aside the Fairphone Fairbuds XL, which is years ahead on that feature, recent examples such as the Marshall Milton ANC and the Sennheiser Momentum 5 Wireless show that the door is already ajar.

At 260 g, the Live 780NC is among the slimmer performers on the market. That does not translate into perfect comfort. Perhaps even more than a Sony WH-1000XM6, it can create pressure on the crown of the head during long sessions. The pads are soft and reasonably deep, and clamping force is more measured than before, but the slightly thinner headband is not padded enough and costs the headphone a few points. It is a shame, because the 780NC has improved in every other respect, including stability and the sense of airiness.

JBL has slightly simplified the formula compared with the previous generation, still mixing a touch surface with physical buttons. There is nothing unusual here: the touch-sensitive back of the right earcup handles navigation and the voice assistant; a slider on the right edge acts as the power and pairing control; a button cycles through the noise-cancelling modes; and volume sits on the left edge.

In practice it is all fairly intuitive. The loss of the multifunction button, which admittedly duplicated the touch zone, does make the experience less pleasant, and the touch surface tends to stutter slightly as soon as you go beyond a simple tap. Neither issue is dramatic, since the noise-cancelling button can be reconfigured to take on playback navigation as well.

Equipped with a modern Bluetooth 6.0 chip, the Live 780NC is at the sharp end for connectivity. Alongside Fast Pair and Swift Pair, multipoint support and the LDAC codec, it includes the LE Audio standard and Auracast. That is a useful way, among other things, to expand the list of products compatible with the Smart Tx transmitter.

The standard, non-LE Audio Bluetooth connection is very stable and latency is fairly well contained, measured at 150 ms. Enabling the low-latency Video mode brought no real improvement.

The trade-off for that wireless modernity is a slightly neglected wired side. A supplied 3.5 mm-to-USB-C cable still allows an analogue connection, but USB-C audio transmission is apparently not supported.

The JBL Headphones app scores highly once again. Particularly rich in settings and assorted features while remaining very intuitive, it makes the most of the Live 780NC.

Organised into three tabs covering general settings, audio and other options, it gives access to the most common functions such as noise cancelling and transparency mode, while opening up personalisation options that are almost never found elsewhere. Alongside completely unrestricted control mapping, a 10-band equaliser and the addition of spatial audio, the app can generate relaxing background sounds, offers specific voice settings for calls and provides direct access to Auracast streams without going through the phone's own menus, which still rarely include the function natively. It was the strongest headphone app in the evaluation.

JBL says little on the subject, but the acoustic architecture appears not to have changed dramatically between the two generations. The Live 780NC uses a 40 mm driver with a polymer diaphragm whose central dome looks unusual, with a textured finish.

Measurements suggest that, in the midrange and treble at least, the brand has the subject well in hand and delivers a thoroughly balanced product. By leaning very heavily on the bottom of the spectrum while relying on average technical quality, however, the driver shows its limits.

As on the Live 770NC, the bass taps are open: the Live 780NC embraces a very pronounced, even inflated low end. From the lower midrange down to the deepest frequencies there is a very clear boost. The sound is powerful, full and round, so round that it unfortunately spills a little into the midrange. The brand retains a certain sense of detail, so the result is surprisingly rich, but it is hard to be entirely satisfied with the lowest notes.

That over-supported bottom end works its way into the character of the product even without smearing the highest frequencies. In a similar way to a Sony 1000X The ColleXion, if in a somewhat different style, it gives the JBL a certain heaviness, as though a light veil had settled over the listening. There is little to criticise in the midrange or the top end. The detail is there despite slightly compressed dynamics, the energy comes through, and a small brightness peak can be picked out.

The result stays close to previous Live products, with fun taking priority over fidelity. The headphone delivers a powerful sound; its exaggerations get in the way of airiness and detail, but it does not lose its bearings and keeps a degree of versatility. Switching on the Studio equaliser preset is nonetheless advisable, since it largely tames the bass boost. The headphone then becomes a calmer, more agreeable listen, though it still cannot hide a fairly ordinary technical level.

Reducing the bass boost does open up the presentation, but it does not transform the detail, the instrument separation or the dynamics of the Live 780NC. Like the Tour One M3, this is a middling performer, no more. The balanced, very Harman-flavoured tuning from the midrange upwards is a good choice, but it does not do everything.

Against the recent Nothing Headphone (a), the comparison is not especially flattering. The JBL is not blown away by its rival, but it sits behind the Nothing model, which is more detailed and more airy while being just as playful. The Live 780NC does improve slightly on the Live 770NC at the top of the spectrum, with a little more finesse and linearity, but some rivals are clearly moving faster.

JBL has not closed its isolation gap on Bose or Apple overnight, but the Live 780NC clearly raises the level compared with its predecessor, which brings it much closer to some higher-end products.

Active isolation is consistent, with no real dips, and pronounced from the lowest frequencies upwards. It peaks around 100 Hz and then holds at a high level, close to 23 to 25 dB in the midrange. For reference, the Live 770NC struggled to reach 15 dB in that region.

Passive attenuation is not harmed by the new earpads, quite the opposite. It is slightly stronger at high frequencies, so that the brightest, most aggressive sounds are reduced almost to nothing. For that type of sound the JBL matches the recent Sennheiser Momentum 5 Wireless or the Sony WH-1000XM6.

In practice a few decibels are still missing, particularly in the upper midrange, before you could genuinely talk about a bubble of silence, but the Live 780NC is a very good noise-cancelling performer.

Transparency mode performs adequately but lacks extension in the treble. The passive attenuation created by the pads is not sufficiently compensated by the processing, which leaves a slightly veiled impression of the surrounding sound.

The balance delivered from the bass up through the midrange does make voices sound reasonably faithful. The mode is usable, if not the most natural available. Unsurprisingly, the TalkThru setting, which concentrates on voices, accentuates that imbalance further, since it lowers the bass level slightly and widens the gap at the top of the spectrum.

Driven by six microphones, three per side, which is close to standard practice now, the hands-free kit does its job well. In quiet surroundings the voice is captured cleanly, despite a few imperfections on high-pitched sounds and sibilants.

In noisy surroundings the noise reduction is very pronounced, but it gradually degrades voice quality. In practice intelligibility is almost always assured, in spite of the occasional mishap. On genuinely noisy public transport the headphone can reach its limits.

As is customary for the Live range, the quoted endurance figures are stratospheric: 50 hours with active noise cancelling and 80 hours without.

In practice those figures are almost exactly borne out, with recorded runtimes of roughly 47 hours 30 minutes with active noise cancelling and 75 hours without. LE Audio is likely to do better still, although that mode was not measured.

The obvious rival is the Nothing Headphone (a). The JBL manages to come out ahead in several areas, including comfort, thanks to its slightly lower weight, marginally stronger active noise cancelling, and support for the LE Audio standard. The Nothing model nonetheless remains the preferred choice on the strength of a more technical and better-balanced approach to sound, even longer battery life and a parametric equaliser. For anyone who wants the best possible noise cancelling with a sound that is just as powerful but more precise, the older Sony WH-1000XM4 remains a strong option.
