JBL Tune 680NC Adaptive Noise-Cancelling Wireless On-Ear Headphones (Black) review

JBL's Tune 680NC is an on-ear Bluetooth ANC headphone whose most useful published distinctions are clear but easy to blur: up to 50 hours with Bluetooth and ANC on, up to 76 hours with ANC off, and a separate powered wired mode with no stated runtime. For the exact Black U.S. item JBLT680NCBLKAM, the maker also lists Bluetooth 6.0 multipoint and an included USB-C-to-3.5 mm audio cable.

Black U.S. item and on-ear fit

The selected JBL U.S. page identifies the Black finish as item JBLT680NCBLKAM and calls the Tune 680NC wireless on-ear noise-cancelling headphones. Blue and White are separately visible finish options with their own U.S. item numbers. This review concerns the Black item, not a color-mixed kit or another Tune-series model.

“On-ear” is a fit distinction, not a comfort verdict. The pads rest against the ears rather than surrounding them, so people who prefer cup enclosure, wear glasses, or notice pressure can have different priorities from someone who wants a smaller foldable headset. JBL lists a 161 g weight and 32 mm drivers; neither number predicts seal, pressure, perceived sound or noise reduction. This is a source-led comparison and does not claim personal wear or testing.

Keep the two Bluetooth battery figures separate

For music over Bluetooth, JBL rates up to 50 hours with ANC on and up to 76 hours with ANC off. The shorter figure is the relevant one when cancellation remains enabled; the longer figure describes a different state. The quick-start guide and U.S. feature copy also give talk-time figures—up to 39 hours with ANC on and 45 hours with it off—which are not substitutes for the music-mode rating. JBL's five-minute speed-charge claim adds up to five hours of play, with about two hours for a full charge. All are manufacturer maxima, not independent measurements or a prediction for an aged battery, loud playback or a particular mix of features.

There is a wording wrinkle in the English specification sheet: its small marketing footnote refers to “ANC and Bluetooth off” before saying 50 hours with them on, while the technical table, U.S. product page and QSG align around 50 hours for Bluetooth plus ANC and 76 hours for Bluetooth with ANC off. I use the consistent values and preserve the discrepancy rather than treating the ambiguous footnote as a third operating mode.

Multipoint means switching, not a runtime promise

JBL describes connecting two Bluetooth devices at the same time and switching between them—for example, keeping a phone available while using a computer or tablet. That is useful if avoiding manual re-pairing is important, but it does not imply that two audio streams play together. JBL does not say its 50-hour ANC-on battery rating was made with two devices linked, so the review treats the multipoint-plus-ANC setup as an unrated plan rather than reusing the single-device number.

Bluetooth 6.0 is listed, but no codec list in the examined U.S. material establishes a particular codec or low-latency behavior. JBL advertises app controls, adaptive ANC, Smart Ambient, TalkThru, spatial sound and Hi-Res listening through the included cable. These are feature descriptions, not evidence of how well a given mode works in a busy cabin, office or call. Decide whether the documented controls match your routine; do not infer an attenuation score or call result.

Analog listening works in a powered mode

The Black package's 1.2 m USB-C-to-analog 3.5 mm cable gives the headphones a wired source option. JBL's quick-start diagram shows wired listening while the headset is powered, with ANC and ambient controls available. That supports a powered analog ANC arrangement. JBL does not publish a separate cable-mode ANC runtime, however, so the 50-hour Bluetooth maximum cannot be carried over to wired operation.

The guide does not establish that music continues through the cable after the headphone is switched off or the battery has run flat. If passive, battery-free audio is essential, treat the Tune 680NC as unconfirmed on that requirement until the exact unit and JBL documentation settle it. This is materially different from a confirmed powered ANC route. The package list includes the audio lead but says the USB-C charging cable is not included; there is no case in the listed box contents. A used seller's contents may differ again.

Where it sits next to Live 680NC

JBL's Live 680NC is another on-ear, Bluetooth 6 model with two-device switching and a 50-hour Bluetooth ANC-on rating. Its maker-listed weight is 231.16 g and it uses a 40 mm driver; Tune 680NC is listed at 161 g with a 32 mm driver. Live's U.S. package lists a carrying pouch and its Live-series controls, while the Tune package centers on the cable and does not list a pouch. Those differences may help narrow a comparison, but they do not establish superior sound, comfort or cancellation for either one.

Before selecting a specific offer, verify the Black item code, the on-ear fit, whether your source accepts a 3.5 mm plug, and whether the charging lead and any case you need are actually included. For long sessions, compare the exact ANC-on rating rather than the more generous ANC-off claim. For two-device use, confirm the handoff behavior you need and plan around an unreported two-link runtime. JBL's published details make those boundaries more useful than a broad “up to 76 hours” headline.
