JBL Tune 670NC

70 hours of battery and ANC that lands in the 98th percentile make the JBL Tune 670NC a budget marvel for silencing the world. Sound quality is average and the on-ear fit can cause fatigue over long sessions, but for travel and work, this is an insane value.

The JBL Tune 670NC lands with a ridiculous 70-hour battery life and noise cancelling that sits comfortably in the top tier of our database. That kind of endurance puts it ahead of nearly everything in its price bracket, and the quick-charge top-up (5 minutes for 3 hours) means you can forget the USB-C cable for most of the week. It's lightweight, foldable, and snaps onto your head with Bluetooth 5.3 multipoint, so swapping between your phone and laptop is effortless.

But here's the trade-off: sound quality is dead average. These 30mm drivers push out JBL's Pure Bass tuning, but don't expect detail or clarity that'll impress an audiophile. Build quality is decent for a $70 to $110 plastic on-ear, and the microphone is just okay. The real draw is the ANC and battery combo. If you commute, travel, or work in noisy environments, the Tune 670NC gives you an insane amount of silence per dollar.

We put the Tune 670NC through our test suite, and the ANC is the headline act. It knocks out low-end hum like airplane engines and office chatter with authority, placing it among the absolute best noise-cancelling performers we've tested, regardless of price. It's adaptive, so it adjusts on the fly, and there's a transparency mode for when you need to hear your surroundings. Connectivity is equally impressive: Bluetooth 5.3 with multipoint pairing is rock-solid, and there's a 3.5mm jack for wired use when the battery finally taps out after nearly three full days of constant playback.

Battery life is a real standout. At the 93rd percentile across all headphones, 70 hours with ANC on is practically laughable compared to the competition. The 30mm dynamic drivers deliver that familiar JBL bass-forward sound that's energetic and fun, but it's not going to reveal hidden layers in your favorite tracks. It sits right at the middle of the pack in sound quality, which is fine for podcasts, pop, and daily streaming, but music lovers who crave detail will want to look up the ladder. Call quality is decent for the price, but the single microphone and NC Mic processing only lift it slightly above average; don't expect studio-grade voice pickup.

At $70 to $110, the Tune 670NC is a screaming deal for anyone who prioritizes ANC and battery. You're getting noise cancelling that rivals headphones priced well over $200, paired with a battery that outlasts almost everything on the market. The sound isn't going to thrill, but for work calls, commuting, and background music, the price-to-performance ratio is hard to touch. The included cable and folding design sweeten the pot. If you find it closer to $70, it's a no-brainer.

Stacked against the Sennheiser MOMENTUM 4, you lose the luxury build and rich, detailed sound but also save over $200. The Sony ULT WEAR brings bigger bass and a more refined app experience, but again, you'll pay almost double. The real rival is the Soundcore Space One, which puts up a similar ANC fight and adds LDAC support, but its 40-hour battery life feels stingy next to JBL's 70 hours. If endurance and noise cancelling are your top concerns, the Tune 670NC undercuts and outlasts the pack.

If you care deeply about sound quality or need headphones for critical listening, look elsewhere. The Tune 670NC's 50th percentile sound ranking means it's fine for casual use but can't compete with even budget studio cans. Those who find on-ear designs uncomfortable after an hour or two will also want to pass, as the clamping force, while light, is still an on-ear affair. Call quality is just okay, so if you spend all day on voice calls, consider a dedicated headset or something with a better microphone array.

The JBL Tune 670NC is a battery and ANC monster disguised as a humble on-ear. It's the perfect pick for budget-conscious commuters and remote workers who want to shut out the world for less than $100. Just keep your expectations in check for sound quality and call performance, and you'll be thrilled.
