How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of over-ear headphones for travel, commuting and Hi-Res music listening, choose Anker Soundcore Space One; if you need a low-latency wireless headset for Xbox, PC and PlayStation gaming with a detachable boom mic, choose BETMI Gaming Headset Compatible.
• Anker Soundcore Space One — biggest strength: Adaptive noise cancelling with upgraded voice reduction, plus 40mm dynamic drivers running LDAC Hi-Res wireless audio and up to 40 hours of playtime with ANC on.
• Anker Soundcore Space One — biggest trade-off: It's a wireless music headphone first, with no boom microphone and no low-latency gaming transmitter, so it isn't built for voice chat in fast multiplayer games.
• BETMI Gaming Headset Compatible — biggest strength: A dedicated 2.4GHz USB dongle with latency rated at ≤20ms, 7.1 surround processing, a detachable AI+ENC noise-cancelling mic and broad platform compatibility.
• BETMI Gaming Headset Compatible — biggest trade-off: It leans on that dongle for its best mode, and its battery figure is rated lower than the Space One's, so it demands more charging discipline.
• Who each pick is for: Space One for the traveler, commuter or student who wants quiet and long battery; BETMI for the console or PC gamer who needs a mic and instant audio feedback.
The Space One is an over-ear travel headphone built around two ideas: killing noise and staying charged. Its adaptive noise cancelling detects what's around you and auto-calibrates, and the voice-reduction structure is tuned to block mid and high frequencies harder than the previous Soundcore generation it's compared against. In practice that's the chatter, the café clatter, the carriage hum — the stuff that ruins a podcast on a busy train. The design also compensates when the fit isn't perfect, so you still get meaningful reduction if the cups sit slightly off.
The audio side is where the 40mm customized dynamic drivers matter. They support LDAC for Hi-Res wireless playback, which the spec sheet frames as three times more detail than standard Bluetooth codecs. The driver size, the 20 Hz to 96 kHz frequency range and the app-controlled unique sound profile tell you this is a listening-first product, not a chat-first one. Bluetooth 5.2 — 5.3 in the item details — plus a 15-metre range covers normal phone-and-laptop life.
BETMI Gaming Headset Compatible: Who It's For
The BETMI headset is the opposite proposition: a gaming peripheral that happens to be wireless. Its core is dual-mode connectivity — a 2.4GHz USB transmitter for serious play and Bluetooth 5.2 for everything else. The 2.4GHz path is the one you want for gaming, and the latency is rated at ≤20ms with a stable range up to 33 feet. Plug the dongle into an Xbox controller and you're set up in one step; the included Type-C to USB-A adapter extends the dongle to PC, Mac, Android TV and PS-5. Bluetooth mode is a double-click away for phones, tablets and Switch.
The 40mm dynamic drivers are paired with 7.1 surround processing, which is the feature that earns its keep in games — directional cues, footsteps, approaching vehicles. The mic setup is unusually flexible: a detachable AI+ENC boom mic plus a built-in mic, with AI algorithms and adaptive environmental noise cancellation working to strip background noise so teammates hear you, not your room. A one-button mute is there for the moments you don't want to be heard.
Physically it's 260 g with a padded adjustable headband, memory protein earmuffs, rotatable foldable cups for storage, and a green LED accent you can switch off. Battery is rated up to 40 hours with a 2.5-hour charge, and the spec sheet's average-life figure is 24 hours — so expect to charge more often than with the Space One if you're running long sessions. Buy it if you play on Xbox Series X/S, Xbox One, PC or PlayStation and want one headset for both console and mobile. Skip it if you mainly want noise cancelling for flights or Hi-Res music.

In my opinion, most people reading this should buy the Anker Soundcore Space One. It's the more versatile product: noise cancelling that adapts, Hi-Res LDAC audio from 40mm drivers, 40 hours with ANC on, 55 with it off, and comfort details like 8° rotating cups. If your priority is competitive or co-op gaming on Xbox, PC or PlayStation and you need a mic with low latency, I'd pick the BETMI Gaming Headset Compatible instead — the 2.4GHz dongle, 7.1 surround and detachable AI+ENC mic are exactly what that job needs. Two different tools, two different buyers.
what is 40mm driver in headphones
A 40mm driver is the circular speaker unit inside the ear cup, measured across at 40 millimetres. Both the Space One and the BETMI headset use a 40mm dynamic driver, which is a common size for over-ear headphones because it balances air movement, weight and comfort.
what are 40mm drivers in headphones
They're dynamic drivers — a diaphragm, voice coil and magnet assembly — sized at 40mm. In these two products the 40mm figure is the audio driver size listed in the specs; the Space One pairs its 40mm customized drivers with LDAC Hi-Res support, while the BETMI pairs its 40mm speakers with 7.1 surround processing.
which driver is best for headphones
There's no single best driver size. Bigger drivers can move more air, smaller ones can react faster, and the tuning, enclosure and codec support usually matter more than the number. A 40mm dynamic driver is a sensible middle ground, which is why both of these headphones use one.
is 40mm driver good for headphones
Yes — 40mm is a well-established size for over-ear headphones and shows up in both products here. Whether it sounds good to you depends on the rest of the design: the Space One's ANC, app-controlled sound profile and LDAC support, or the BETMI's 7.1 surround and low-latency 2.4GHz connection.
