JBL Live 670NC

The JBL Live 670NC packs best-in-class noise cancelling and a ridiculous 76-hour battery into a lightweight, foldable frame. Sound is fun and bass-forward, though the on-ear fit isn't for everyone. If you find it at a good price, it's a killer value for ANC junkies.

The JBL Live 670NC is a bit of a shapeshifter. The spec sheet screams 'commuter champ' with its absurd 76-hour battery life and top-tier noise cancelling, but the name and some of the marketing copy keep referencing the Tune 780NC, which feels like a copy-paste slip-up from JBL's side. Ignore the naming confusion for a second and you're left with a feature-packed set of on-ear cans that fold flat and barely weigh anything.

Let's talk about that ANC first because it's the absolute best right now, landing in the 98th percentile of our database. It chews through background hum and chatty coffee shop noise without breaking a sweat. The sound is solid, with that punchy JBL Pure Bass giving tracks real energy, though it's not the most detailed profile we've heard, sitting around the 73rd percentile. Call quality is a strong point thanks to those beamforming mics, and the multipoint connection is seamless. The weak spot is the on-ear design itself, which just can't compete with over-ear cans for passive isolation or long-term comfort if you wear glasses.

Pricing is all over the map for this one, with a wild spread from $45 to over a grand depending on the vendor. If you can snag it at the lower end of that range, you're getting a steal for the ANC and battery performance alone. At the higher end, you're being ripped off, plain and simple. This is a budget-friendly feature monster, not a premium audiophile device, so shop smart and don't overpay.

Stacked against the Sony ULT WEAR, the JBL wins on sheer battery stamina but loses on overall sound refinement and that deep, bass-heavy rumble Sony is known for. The Soundcore Space One offers a very similar feature set with a more comfortable over-ear design and often at a comparable price, making it a direct threat. The Audio-Technica ATH-S300BT is the dark horse here, offering a more balanced, mature sound signature if you find the JBL's bass a bit too boomy, though its ANC can't touch the JBL's performance.

Skip these if you're an audiophile chasing a wide soundstage and pristine detail, the studio score of 63.5 tells you everything you need to know. Also look elsewhere if you hate the pressure of on-ear headphones or need a pair that can survive a toddler's tantrum, as the build quality isn't the most rugged.

If you need a pair of headphones that can outlast a cross-continental flight and kill the drone of a jet engine for under a hundred bucks, this is your pick. It's a practical workhorse built for commuters and remote workers who prioritize battery life and noise cancelling above all else.
