JBL Live 670NC Review: Are These On-Ear ANC Headphones Worth It?

In short:

The JBL Live 670NC is a mid-range pair of wireless on-ear headphones that isn't chasing audiophile glory — it's chasing comfort, battery life, and decent noise cancelling at a price nowhere near Sony or Bose territory. Get them if you want something that just works for the daily grind: commute, office, gym. Skip them if you're used to premium bass response and want the best ANC money can buy — that's not what's on offer here.

There's a category of headphones you don't buy because you've dreamed about them for years — you buy them because your old pair died yesterday, and tomorrow you've got a four-hour train ride and a stack of podcasts to get through in relative peace. That's exactly the job the JBL Live 670NC was built for. Not a flagship, not something your coworkers will envy — just a tool that does its job, day after day.

What this thing actually is

On-ear, not over-ear — and that distinction matters. The ear cup doesn't fully enclose your ear; it rests on it instead. For some people that's a win: your head stays cooler in summer, your ears don't start sweating after three hours the way they do with some full-size models. For others it's a drawback: passive sound isolation is weaker, so all the noise-blocking work falls on the electronics. That's where JBL leaned on Adaptive Noise Cancelling — a system that reads the ambient noise around you and adjusts the cancellation level accordingly, instead of just slamming everything to maximum regardless of context.

In practice, it holds up well on a plane, on the subway, in an open-plan office humming with air conditioning. Don't expect the "the world just went silent" effect you get from Sony's top models — this is more like turning the volume down on your surroundings than full immersion in a vacuum. There's also Smart Ambient, a transparency mode for when you need to catch a platform announcement or answer a coworker without pulling the headphones off. It's implemented with no noticeable lag, and the outside sound comes through naturally, without the tinny hiss that plagues cheaper alternatives.

Living with them day to day

Picture a manager who spends half the day on calls and the other half hiding in a playlist to survive the open office. Or a student commuting to campus with multiple transfers who wants to get through lecture recordings without headphones that start pinching the temples after an hour. Both of those are exactly the audience for the JBL Live 670NC. The build is light, the ear pads are soft, and — this is the important part — you can genuinely wear these for hours without needing to take them off every thirty minutes to rub your ears.

Battery life is a real strength: the rated runtime lets you forget about charging for several days of active use, and fast charging bails you out on the nights you forgot to plug in. Stacked against the obvious competitor in this space, the Sony WH-1000XM6, the JBL loses on noise cancelling quality and sound detail — worth admitting up front. Sony is still king here, and if your budget stretches and silence is non-negotiable (frequent flights, a loud office every single day), the premium is justified. But the Live 670NC wins on the flip side: the price is meaningfully lower, and for a lot of people the difference in on-head comfort is barely noticeable.

JBL's sound has always leaned toward bass-forward — it's basically the company's signature, and the 670NC doesn't break the pattern. This isn't a neutral, "studio-flat" tuning; it's built for fun. Hip-hop, pop, electronic music sound punchy, with low end you can feel. Audiophiles chasing accurate reproduction for jazz or classical might come away disappointed — that's just not the profile here. But for a daily commute playlist, it's exactly what you want to hear when you hit play on the bus in the morning.

The JBL Headphones app gives you basic EQ control, ANC level selection, and firmware updates. Nothing groundbreaking, but it runs stable, without the glitches that sometimes plague budget brands. The Bluetooth connection holds firm, and multipoint pairing to two devices at once is a nice bonus for anyone who bounces between a laptop and a phone all day.

The honest verdict

Buy these if: you want comfortable on-ear headphones for daily use with decent ANC and don't want to pay flagship prices; you value hours of wear without ear fatigue more than a perfect soundstage; you like a warm, bass-forward sound in pop and hip-hop.

Skip these if: you're an audiophile who needs a neutral tonal balance; you fly regularly and want maximum noise cancelling (look toward Sony or Bose instead); you need a fully closed-back design for isolation in very loud environments — the on-ear form factor will always let in more outside sound than an over-ear seal.

Two real trade-offs to weigh. First, the ANC is good but not best-in-class, and if silence is critical for you, there are stronger (and pricier) options out there. Second, that bass-forward sound signature won't land for everyone, especially if you're used to something more neutral. But at this price point, this is one of the few options in its segment that bundles comfortable long-term wear, solid battery life, and adaptive noise cancelling without charging a premium just for the badge on the side — check the full landed price to your country, item plus forwarding plus import duty, on dede.sh before you decide.

FAQ

Is it worth paying more for the Sony WH-1000XM6 instead of the JBL Live 670NC?

If noise cancelling and sound detail are your top priority and the budget allows it, yes — Sony is objectively better here. But if you just want comfortable everyday headphones without paying for flagship status, the JBL covers that need perfectly well.

What's better for travel — the JBL Live 670NC or wireless earbuds?

It comes down to habit. On-ears stay put better during activity and typically last longer on a charge without needing a case top-up; earbuds are more compact and pocket-friendly. For long trips full of podcasts, on-ears usually win because they're more comfortable over multiple hours straight.

Is Adaptive Noise Cancelling enough for an open-plan office?

For dulling AC hum, keyboard clatter, and background chatter — plenty. It won't fully erase the coworker having a loud phone call next to you, but it'll make that noise a lot less intrusive.

How bass-heavy is the JBL Live 670NC, and can you adjust it?

The bass is noticeable right out of the box — it's JBL's signature house sound. The app lets you tweak the EQ toward something more neutral, but you can't fully strip out that low-end emphasis; it's baked into how the drivers are tuned.
