If you want the most advanced noise cancellation and a truly pocketable in-ear design, choose Bose QuietComfort; if you need marathon battery life and a big over-ear fit for all-day desk work, choose Wentronic Y01.
• Bose QuietComfort — biggest strength: A full noise-cancellation toolkit — CustomTune ear analysis, ActiveSense, adjustable noise control and Immersive Audio spatialisation — in a tiny in-ear bud.
• Bose QuietComfort — biggest trade-off: Battery life is measured in hours, not days: up to 6 hours per charge in Quiet or Aware Mode, and as little as 4 with Immersive Audio on.
• Wentronic Y01 — biggest strength: Up to 48 hours of playtime per charge and a 40 mm dynamic driver with a 20 Hz–40 kHz range, all in a foldable over-ear frame.
• Wentronic Y01 — biggest trade-off: It is a button-controlled, wired-or-wireless over-ear with no app layer, no ear-fitting system and no spatial audio — the ANC is a single on/off feature.
• Who each pick is for: Bose QuietComfort suits commuters, flyers and anyone who wants maximum quiet in the smallest possible package; Wentronic Y01 suits long-session listeners — students, remote workers, gamers — who hate charging.
The Bose QuietComfort Ultra Earbuds (2nd Gen) are built around one idea: make the outside world disappear as completely as possible from a bud that sits inside your ear. The feature list backs that up. CustomTune analyses your ear and adapts the sound and cancellation to its shape, ActiveSense smooths out sudden spikes in surrounding noise even while you're in Aware Mode, and you can dial noise cancellation up or down — or switch it off entirely to save battery — without digging through preset Modes.
The fit system is unusually thorough for earbuds: nine combinations of eartips and stability bands (three tip sizes, three band sizes), with umbrella-shaped tips that seal the ear opening and bands that hug the bud in place. Comfort and seal are the two things that make or break in-ear ANC, so it makes sense that Bose spent its engineering budget there. Call quality gets its own technology too — SpeechClarity uses noise-rejecting mics to filter wind and background chatter, and you can take calls on one bud or both.
Battery is the honest catch. You get up to 6 hours in Quiet or Aware Mode, up to 4 hours with Immersive Audio engaged, and the case holds three additional full charges. Recharging is via USB-C or wirelessly. Bluetooth 5.3 with a 30-foot range, IPX4 water resistance, app-based control, and a Desert Gold finish round out the package.
Buy it if you commute, fly, work in open offices or study in noisy rooms, and you value the smallest possible carry footprint. Skip it if you regularly listen for eight-plus hours without a charging break, or you simply prefer the feel of a headband over something inside your ear canal.
The Wentronic Y01 takes the opposite approach: instead of shrinking everything into a bud, it goes big on the two things over-ear headphones do better — runtime and driver size. The headline figure is 48 hours of average battery life from a 2-hour charge. That is a genuinely different category of endurance. For someone who works at a desk eight hours a day, that could mean charging roughly once a week rather than every day or two.
The audio hardware is a 40 mm dynamic driver covering 20 Hz to 40 kHz, which extends well past the 20 kHz ceiling of the Bose set — relevant for hi-res sources, since the Y01 is advertised with Hi-Res Audio support. The build is over-ear with oval earpieces and leather enclosure material in Pink. It folds, which matters if you commute with a backpack, and it ships with both a 3.5 mm audio cord and a charging cable — so the 3.5 mm jack gives you a wired fallback when the battery is empty or when you want zero latency.
Features include Bluetooth 5.3, active noise cancellation, dual device pairing, and hands-free calling via the built-in microphone, with button controls on the earcup rather than an app. It's listed as compatible with iOS, Android and PC, and carries a 1-year warranty.
Buy it if you want one pair for long days at a desk, you like the security of a headband, you want a wired option as a backup, or you connect to a laptop and a phone at the same time. Skip it if you need the most refined adaptive noise cancellation, spatial audio, or a compact case that slips into a jeans pocket — those are not what this headphone is designed around.
• Best for noise cancellation depth → Bose QuietComfort. CustomTune, ActiveSense and adjustable ANC are a multi-layer system; the Y01 offers ANC as a single feature.
• Best for battery life → Wentronic Y01. Up to 48 hours versus up to 6 hours plus three case charges. Not close.
• Best for travel and commuting → Bose QuietComfort. In-ear, IPX4, wireless charging case, tiny footprint.
• Best for long desk or study sessions → Wentronic Y01. You can go days between charges and never think about it.
• Best for spatial/immersive listening → Bose QuietComfort. Immersive Audio is exclusive to the Bose set.
• Best for wired fallback and PC use → Wentronic Y01. The 3.5 mm cable and dual device pairing make it a natural laptop companion.
• Best for fit personalisation → Bose QuietComfort. Nine eartip and stability band combinations versus a fixed over-ear frame.
• Best for call clarity in wind and noise → Bose QuietComfort. SpeechClarity with noise-rejecting mics is purpose-built for this.
• Best for the widest frequency range on paper → Wentronic Y01. 20 Hz–40 kHz versus 20 Hz–20 kHz.
In my opinion, the right answer depends entirely on which problem you're solving. If your priority is silencing a noisy commute, a flight, or a loud office in the smallest possible package, I would buy the Bose QuietComfort Ultra Earbuds (2nd Gen) — the CustomTune and ActiveSense stack, the nine-way fit system and Immersive Audio are exactly what in-ear noise cancellation is supposed to be, and I'd accept the shorter runtime as the price of that design.
But if you're a desk worker, student or PC user who wants to charge once a week, plug in a 3.5 mm cable when needed and pair two devices at once, I would buy the Wentronic Y01. Forty-eight hours and a 40 mm driver in a foldable over-ear is a very sensible brief. Check the current price on Amazon for both before you commit, since that's the one variable that can flip this decision.
how to headphones work
Headphones convert an electrical audio signal into sound waves using a driver. The Bose QuietComfort uses a custom driver in an in-ear design with active noise cancellation and CustomTune ear analysis; the Wentronic Y01 uses a 40 mm dynamic driver in an over-ear frame with active noise cancellation. Both connect wirelessly over Bluetooth 5.3.
how to headphones on iphone
Both are wireless Bluetooth headphones, so you pair them from your iPhone's Bluetooth settings menu. The Bose set is controlled through its companion app, while the Wentronic Y01 uses push-button controls on the earcup and is listed as compatible with iOS, Android and PC. The Y01 also includes a 3.5 mm audio cord if you prefer a wired connection.
how to headphone mode off
Noise cancellation can be switched off on both. On the Bose QuietComfort you adjust noise control in the app, including turning cancellation off completely to conserve battery. On the Wentronic Y01, noise control is handled by the push-button controls on the headphone itself.
how to headphones
If you mean how to choose between them: pick the Bose QuietComfort for in-ear portability, the deepest adaptive noise cancellation and Immersive Audio. Pick the Wentronic Y01 for up to 48 hours of battery, a 40 mm driver with a 20 Hz–40 kHz range, a foldable over-ear fit and a 3.5 mm wired option.
