How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want wired, all-day noise cancelling with an Aware mode and no charging anxiety, choose Bose QuietComfort 20; if you need true wireless earbuds with spatial audio, CustomTune noise cancellation and multipoint Bluetooth, choose Amazon Renewed Bose QuietComfort.
• Bose QuietComfort 20 — biggest strength: in-ear active noise cancellation that Bose claims rivals full-sized headphones, plus up to 16 hours of battery and an Aware mode that lets the outside world back in.
• Bose QuietComfort 20 — biggest trade-off: it's a wired 3.5 mm headphone with a built-in rechargeable battery, so you're tethered to your phone and you have to remember to charge the inline module.
• Amazon Renewed Bose QuietComfort — biggest strength: fully wireless QuietComfort Ultra earbuds with spatial audio, three listening modes (Quiet, Aware, Immersion), multipoint Bluetooth and a charging case.
• Amazon Renewed Bose QuietComfort — biggest trade-off: only up to 6 hours per charge (4 with Immersive Audio), no headphone jack at all, plastic build, and it's a renewed unit backed by a 90-day limited warranty rather than a new-in-box product.
• Who each pick is for: the QuietComfort 20 suits commuters, flyers and Android/BlackBerry/Windows phone users who value long battery life and a cable; the Renewed QuietComfort suits people who want modern wireless conveniences and don't mind a shorter runtime.
• Reality check: neither of these is a "new flagship." One is a legacy wired model, the other is a renewed pair of newer earbuds. Buy the one that matches your lifestyle, not the one that sounds newer.
The QuietComfort 20 is Bose's original in-ear noise cancelling headphone, and it's built around a very specific idea: give you the noise reduction of a big over-ear headphone in something that tucks into your ears. Bose uses its TriPort technology for the sound and a set of exclusive technologies for the noise cancellation, and the company describes the result as rivaling any full-sized headphone. Whether or not you buy that claim outright, the design intent is clear — this is a headphone for shutting out a plane cabin, a train carriage or an open-plan office.
What makes it genuinely useful day to day is the Aware mode. Flip it on and the noise cancelling steps back so you can hear announcements, a barista, or traffic while your music keeps playing. That single feature is what separates it from a lot of cheap noise cancellers, and for a commuter it's the difference between taking your earbuds out every five minutes or just leaving them in. The proprietary StayHear+ tips come in three sizes (small, medium, large) and are designed to sit softly and securely without you jamming them into your ear canals, and Bose includes a clothing clip to keep the cable from snagging.
Who should buy it: frequent flyers and commuters who want strong noise cancelling, an Aware mode, a 3.5 mm wired connection and long battery life from a single charge. Who should skip it: anyone who has moved on from the headphone jack, wants true wireless freedom, or needs the newest Bluetooth conveniences like multipoint switching. If you're on a modern phone with no 3.5 mm port, you'll need to think hard about adapters before you commit.
Amazon Renewed Bose QuietComfort: Who It's For
The Amazon Renewed Bose QuietComfort is a renewed pair of Bose QuietComfort Ultra noise cancelling earbuds in Lunar Blue. That's the key thing to understand: this isn't a different, cheaper headphone design — it's Bose's current-generation flagship earbud formula, sold as a renewed unit. You're getting genuinely modern features here that the QuietComfort 20 simply doesn't have.
The most interesting is CustomTune. Bose's technology analyzes each ear and adapts the sound and the active noise cancellation to your specific ears, so the noise cancelling is tailored rather than one-size-fits-all. Then there's Bose Immersive Audio, which places the sound in front of you for a more spatial, out-of-your-head presentation. You get three listening modes to match: Quiet Mode for maximum cancellation, Aware Mode to hear your surroundings, and Immersion Mode which combines full noise cancelling with Immersive Audio. That's a meaningful step up in flexibility, and it's the main reason someone would pick these over the older wired model.
Fit is handled with Bose's Fit Kit — nine total combinations across three pairs of ear tips (small, medium, large) and three pairs of stability bands, so you can dial in something snug for long sessions. The earbuds are touch controlled, so you swipe and tap to change volume, skip tracks, switch modes and take calls, and noise-rejecting microphones clean up background noise on those calls. Bluetooth multipoint is a real quality-of-life feature too: you can be connected to your laptop and your phone at once and switch between them without re-pairing, with a listed range of around 30 feet.
The trade-offs are worth stating plainly. Battery life is up to 6 hours, dropping to about 4 hours with Immersive Audio on, and a 20-minute charge gives you roughly 2 hours of extra playtime — the charging case fills in the gaps, but this is a fraction of the QuietComfort 20's 16 hours. There's no headphone jack, the enclosure is plastic, and you should be clear-eyed about the renewed part: this is a renewed product backed by a 90-day limited warranty, not a brand-new retail unit, and the package is a plain FFP box with the earbuds, Fit Kit, charging case, USB-C cable and safety sheet.
Side-by-Side: Which Should You Choose?
• Best for battery life → Bose QuietComfort 20. Up to 16 hours versus up to 6 hours (4 with Immersive Audio). It's not close.
• Best for modern features → Amazon Renewed Bose QuietComfort. Spatial audio, CustomTune, three listening modes, touch controls and multipoint Bluetooth are all things the QuietComfort 20 doesn't offer.
• Best for flying and long commutes → Bose QuietComfort 20. Long runtime plus a wired connection that never drops, and an Aware mode for gate announcements.
• Best for switching between laptop and phone → Amazon Renewed Bose QuietComfort. Bluetooth multipoint makes that seamless; the wired model can't do it.
• Best for phones without a headphone jack → Amazon Renewed Bose QuietComfort. It's wireless only, which is exactly what modern phones expect.
• Best for people who hate charging another gadget → Bose QuietComfort 20. One charge lasts most of a week of commuting; the Ultra earbuds want topping up in their case.
• Best for a tailored fit → Amazon Renewed Bose QuietComfort. Nine tip-and-band combinations versus three tip sizes.
• Best for warranty peace of mind → Bose QuietComfort 20. It's a standard new Bose product; the renewed pair carries a 90-day limited warranty.
In my opinion, most people shopping this comparison should buy the Bose QuietComfort 20. The reason is simple: 16 hours of battery, a wired connection that never disconnects, and an Aware mode that covers the single most common use case for noise cancelling — commuting and travel. If you don't mind charging a case and you specifically want spatial audio, CustomTune cancellation and multipoint Bluetooth, then the Amazon Renewed Bose QuietComfort is the better modern pick. But if you're torn, I'd take the longer battery life and the cable reliability. Either way, check the current price on Amazon before you decide, since renewed and legacy pricing moves around.
FAQ
No. The renewal listing shows no headphone jack — they're Bluetooth wireless only, with a charging case and USB-C cable in the box. If you need a 3.5 mm wired connection, the QuietComfort 20 is the one with the jack.
The Bose QuietComfort 20 gives up to 16 hours of use from its built-in rechargeable battery. The Amazon Renewed Bose QuietComfort earbuds give up to 6 hours, dropping to about 4 hours with Immersive Audio, plus roughly 2 extra hours from a 20-minute charge in the case.
That's a judgment call. Renewed units are backed by a 90-day limited warranty and ship with the earbuds, Fit Kit, charging case and cable, so you get the full feature set at a lower cost than new. If you want a brand-new product with a full manufacturer warranty, buy the QuietComfort 20 instead.
