The JBL Tune 670NC is a commuter-first on-ear headphone: 70-hour battery, 174 g weight, multipoint and a useful app carry it, while weak out-of-the-box bass and average ANC hold it back. Buy it for portability and stamina; if bass punch or stronger silence matters more, look at the Sony rival TechRadar preferred instead.
— THE VERDICT · JUDGEANY EDITORSWhy the Tune 670NC still matters
Launched in August 2023, the JBL Tune 670NC is an on-ear headphone built around one headline number — up to 70 hours of playback with noise cancelling off, and 44 hours with it on. At 174 g it is lighter than most over-ear rivals, it folds flat for a bag, and it pairs with two devices at once. This review aggregates manufacturer specs, TechRadar's published review findings, and owner-facing coverage. JudgeAny runs no test lab; the scores below are editorial judgments built on that evidence.
Battery life: the strongest card
JBL rates the Tune 670NC at 70 hours with Bluetooth on and ANC off, and 44 hours with ANC on, with a full recharge taking 2 hours over USB-C. A 5-minute speed charge adds 3 hours of playback. TechRadar's reviewer found the 70-hour claim easy to reach with ANC off, and still got 44 hours with it on. In practice, that means charging roughly once a week for most listeners. Talk time is rated at up to 30 hours with ANC on and 39 hours with it off, according to Crutchfield's listing.
Sound: quiet out of the box, better with EQ
TechRadar's verdict on sound is blunt: out of the box, the Tune 670NC sounds surprisingly weak. The reviewer ended up sticking with the Vocal EQ preset for most music, because it was loud enough to hear confidently without cranking the volume. Switching to the Bass preset had the opposite effect: the bass came out weak and lacking any punch, and it never got strong even after tweaking. Foo Fighters' All My Life sounded less exciting than usual, while Eminem's Lose Yourself suited the vocal-forward tuning better. The hardware is a pair of 32 mm dynamic drivers, rated 20 Hz to 20 kHz at 98 dB sensitivity, and the JBL Headphones app offers preset EQ modes plus a custom curve, so the stock tuning is a starting point rather than a verdict.
Noise cancelling: average, and the on-ear fit is why
The Tune 670NC uses adaptive noise cancelling, with Ambient Aware and TalkThru modes for letting the surroundings in without removing the headphones. TechRadar found the ANC only average, and blamed the form factor: because the cups sit on the ears rather than around them, environmental sound leaks in. On a busy road, traffic was still audible, although the ANC did take the edge off some of the more annoying elements. For steady office hum and study sessions it is a reasonable damper — for total silence it is not the right pick. There is also no wear detection, so removing the headphones does not pause playback automatically.
Design, comfort and the app
At 174 g, the Tune 670NC is genuinely light, and TechRadar found it mostly comfortable, with no pinching and a headband that adjusts without an awkward clunk. The trade-off is feel: the headband and ear cups are plasticky and a bit cheap, and the foam ear cups get warm and sweaty in hot weather during long sessions. The cups fold inward for storage, and a simple cotton bag comes in the box. Controls are traditional buttons on the right ear cup for power, volume and ambient modes. Multipoint pairing with two devices worked reliably in TechRadar's review, and the JBL Headphones app is simple to use, with EQ presets, a custom curve, voice assistant setup and ANC adjustment. Bluetooth is version 5.3, LE Audio is promised via a later over-the-air update according to JBL, and a detachable 3.5 mm cable covers wired listening.
Where the evidence disagrees
JBL markets Pure Bass sound, and owner summaries praise the sound overall, but TechRadar's reviewer found the bass weak even on the Bass preset. Owner ratings lean friendlier in general: Amazon's Canadian listing averaged 4.4 out of 5 stars across roughly 1,900 ratings. The gap is probably fit and preset choice: on-ear seal varies with head shape, and the Vocal preset, not Bass, was the reviewer's daily pick. Battery shows a smaller split: Target's guest-review summary records some owners complaining about battery life despite the 70-hour rating, while TechRadar reached the rated figures. The practical read is that rated hours reflect moderate use, and heavy ANC-on listening at high volume will land lower. One more footnote for buyers: JBL's support page names the Tune 680NC as this model's successor while still listing the 670NC as manufactured from 2023 until now, so it is worth comparing the two before buying.
Who should buy it
The Tune 670NC suits students and commuters who want light, foldable headphones they rarely need to charge, with multipoint for juggling a phone and a tablet. If bass punch or the strongest silence matters more, TechRadar favored the Sony WH-CH720N instead, which sounds better but is heavier at 192 g with shorter battery life.
