JBL Tune 670NC

The JBL Tune 670NC on-ear headphones deliver absurd 70-hour battery life and top-shelf adaptive ANC in a lightweight, foldable package. Sound is bass-forward but average in clarity, and the on-ear comfort might not suit all-day use. At the right price (around $70), they're a steal for commuters and travelers who want ANC without recharging every few days.

If you're hunting for an on-ear pair of ANC headphones that won't die halfway through your week, the JBL Tune 670NC is one of the most interesting options out there. The battery life sits at a ridiculous 70 hours, which means even heavy daily use might only require a charge every two weeks. That kind of endurance, paired with adaptive noise cancelling that holds its own against pricier models, makes these a prime candidate for long commutes, travel, or just drowning out a noisy office.

Build-wise, they fold flat and weigh just 174g, so stuffing them into a bag isn't a chore. The on-ear design keeps things compact, but you'll feel that clamping force over several hours. Still, the comfort rating in our database lands them well above average for on-ear headphones, and the cushions are plush enough for most people.

Connectivity is where the Tune 670NC really flexes, with Bluetooth 5.3, multipoint for two devices at once, and a 3.5mm jack for wired backup. Voice calls get a single mic with noise cancellation, which is fine for a quick chat but not spectacular. At prices that can dip as low as $70 from some sellers, this feels like a steal. Just be aware that if you're seeing them above $200, you're being overcharged.

Noise cancelling on the Tune 670NC is a genuine standout. We'd rank it best-in-class for on-ear models, easily rivaling some over-ear options that cost double. In our measurements, it sits in the 98th percentile, meaning the adaptive ANC blocks out low-end rumble and chatter with surprising efficiency. You also get a Smart Ambient mode that pipes in your surroundings when you need it, which works as advertised.

Sound quality is more of a mixed bag. The 32mm dynamic drivers push JBL's signature bass-forward tuning, and the low end hits hard enough to keep beat-driven playlists engaging. But overall clarity lands at about the midpoint of all headphones we've tested, so you won't find the kind of crisp detail a good over-ear set delivers. For podcasts, pop, and hip-hop during your commute, it's perfectly enjoyable. If you're looking for a neutral reference sound for studio work, though, the Tune 670NC isn't built for that.

Value here is a two-sided story. The street price can swing from a reasonable $70 all the way up to an eye-watering $1,259, which is either a mistake or someone trying to pull a fast one. At the low end, these are a ridiculous bargain, you're getting ANC that rivals the Sony ULT WEAR and battery life that humiliates almost everything else, for lunch money. If you're paying above $120, you're edging into territory where over-ear alternatives like the Soundcore Space One or the Audio-Technica ATH-S300BT give you better comfort and clearer sound. The key is finding a listing from a reputable store near that $70 mark, if you do, it's a no-brainer for budget ANC on-ears.

Stacked against the Soundcore Space One, the JBL wins on battery life by a landslide (70h vs 40h with ANC off), and its ANC feels slightly more effective for low-frequency noise. But the Space One offers a more spacious over-ear design and often sounds cleaner in the mids. The Sony ULT WEAR WHULT900N/B sits a tier above in price, yet its sound quality and call performance outstrip the Tune 670NC by a noticeable margin, though you'll sacrifice some of that marathon battery life. If you want an on-ear form factor specifically, the Audio-Technica ATH-S300BT is a direct competitor with a flatter sound signature but shorter battery, and it typically costs more than the JBL's bargain basement pricing. For pure battery endurance and ANC punch per dollar, the Tune 670NC is hard to beat unless you need the all-day comfort of over-ear cups.

If you're a critical listener who wants detailed, airy soundstage, the bass-heavy tuning and average clarity won't satisfy you, look at the Sennheiser MOMENTUM 4 or even the Soundcore Space One for a cleaner over-ear experience. Anyone who plans to wear headphones for an entire workday without breaks should consider over-ear models instead, the on-ear pressure of the Tune 670NC will likely become annoying after the second hour. And if you take lots of calls in noisy places, the mic quality here is mediocre, so a headset with more mics like the Sony ULT WEAR will serve you better.

The JBL Tune 670NC makes a lot of sense if you value battery life and noise cancelling above everything else, and you don't mind the on-ear fit. It's tailor-made for long travel days, open-plan offices, or anyone who forgets to charge their headphones constantly. The bassy sound is fun for casual listening, even if it won't wow an audiophile.

The catch is comfort. If you've got larger ears or plan to wear your headphones for 4+ hours straight, you'll likely feel the pinch. And if you see these listed for more than $150, walk away, you can get a true over-ear set with similar ANC and vastly better comfort for the same money. But at the $70-ish price point, it's one of the best budget noise-cancelling options you can throw in your bag.
