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 wireless over-ear headphones that does music, gaming audio and hands-free calls on a single charge, choose XuanGui Headphones; if you need a wired single-ear headset that plugs into basically anything and keeps one ear open to the room, choose Crotrain One Ear Headset. These are two very different tools, and picking the wrong one is the main way people end up disappointed.
• XuanGui's biggest strength: a full wireless over-ear package — Bluetooth 5.3, a built-in HD mic, around 20 hours of playtime per charge, FM radio and TF/microSD card playback, all in a 200 g foldable frame.
• XuanGui's biggest trade-off: it's a stereo pair with no wired-first design, so it's the wrong tool if you specifically want a single earpiece with an open ear.
• Crotrain's biggest strength: three connection paths in one box (3.5 mm, plus a 3.5 mm-to-Type-C cable and a Type-C-to-USB adapter), so it works with consoles, PCs, laptops, Macs and phones without hunting for dongles.
• Crotrain's biggest trade-off: it's wired and mono — the earcup and boom mic are left-ear only, and there's no battery, no Bluetooth, no music-first tuning.
• Pick XuanGui if you want one headphone for commuting, studying, movies and casual gaming at home.
• Pick Crotrain if you want a lightweight, always-ready chat headset for meetings, support calls and console voice chat.
The XuanGui NX200 is built around one idea: give you a complete, self-contained listening device. Bluetooth 5.3 handles the connection, and the spec sheet lists a 10-metre Bluetooth range, a 400 mAh battery, a 2-hour charge time and roughly 20 hours of playback. That's a full workday plus an evening, from a single top-up. There's also a 3.5 mm jack on board, so you're not completely stranded if you'd rather go wired.
What makes it more flexible than a basic Bluetooth headphone is the built-in media. There's an FM radio tuner, and the earcups accept a microSD/TF card, which means you can load music onto a card and listen without pairing to anything at all. For travel, that's genuinely useful — no phone, no problem. The drivers are dynamic, rated 32 ohm with a 20 Hz–20,000 Hz frequency range, which is the standard full-range band you'd expect at this level. The memory-protein foam cushions and adjustable headband are meant to spread pressure rather than clamp, and at 200 g the whole thing folds down small enough to drop in a bag.
Who should buy it: students, home-office workers, travellers and casual gamers who want one pair of headphones for music, video and voice. The HD microphone covers calls and in-game chat without a separate boom. It connects to Bluetooth-enabled devices — PC, laptop, tablet, phone, and consoles that support Bluetooth audio — and after the first pairing it reconnects automatically when you power it on.
Who should skip it: anyone who needs a wired, low-latency connection as the primary path, or who specifically wants a single-ear design. This is also not an active noise-cancelling headphone. The listing describes passive isolation from the soft, sealing ear cushions, and the noise-control field is listed as none — the cushioning reduces background noise by covering your ears, it doesn't cancel it electronically. If you need real ANC, look elsewhere.
The Crotrain AQ880 is the opposite philosophy: one ear, one cable, zero setup drama. The core of the design is a single 3.5 mm jack, and Crotrain ships the adapters in the box — a 3.5 mm-to-Type-C cable and a Type-C-to-USB adapter. That combination is what makes the compatibility claim real rather than marketing: PS5, PS4, Xbox One and Series X/S, Switch and Switch 2, PC, laptops, tablets, iPad, and iOS/Android phones are all covered by one of those three paths.
The 50 mm dynamic driver is the headline audio spec, and it's a large driver for a single-ear headset — the intent is clear, intelligible voice and game audio rather than a wide stereo stage. The microphone rotates up and down through 120 degrees so you can position it near your mouth and swing it out of the way between calls. Volume and mic mute sit on an inline controller, which is the right call for a headset you'll wear for hours of meetings; you're not reaching for your keyboard to mute.
Two design details matter more than they look. First, the open earmuff design: it deliberately lets room sound in alongside the earpiece audio, so you can hear a colleague walk up or a doorbell while you're on a call. Second, and this is the one people miss — the earcup and microphone are left-ear only. Crotrain states it plainly, and it's repeated in the description. If you're a right-ear-only person, this headset is not for you, and no adapter fixes that.
The fit is soft protein memory foam on an adjustable headband, with a 6.6-foot braided cable that gives you real slack to stand up or shift in your chair. The build is ABS with faux leather, and it's a modern, plain black design — it reads as office equipment, which is exactly what it is.
Who should buy it: people who live in voice chat — remote workers on back-to-back calls, support and sales staff, teachers running online sessions, and console players who want game audio plus party chat without a bulky dual-ear cup. The open-ear design and the single-sided fit are the whole point.
Who should skip it: anyone who wants to listen to music properly, anyone who wants wireless freedom, and anyone who needs the earcup on the right side. There's no battery here, so there's also no charging routine — but there's also no untethered walking around.
• Best for music and movies → XuanGui Headphones. Stereo over-ear cups, dynamic drivers covering 20 Hz–20,000 Hz, and HiFi stereo tuning are built for full-range listening; the Crotrain is mono by design.
• Best for all-day wireless use → XuanGui Headphones. Around 20 hours of Bluetooth playback from a 400 mAh battery, with a 2-hour charge.
• Best for plug-and-play across many devices → Crotrain One Ear Headset. The 3.5 mm jack plus the included Type-C cable and USB adapter covers consoles, computers and phones in one purchase.
• Best for keeping one ear on your surroundings → Crotrain One Ear Headset. The open earmuff design and single-sided fit are made for shared offices and rooms where you can't fully tune out.
• Best for long meetings and calls → Crotrain One Ear Headset. Inline volume and mic mute, a 120-degree rotating mic, and a 6.6-foot braided cable you can move around on.
• Best for travel and commuting → XuanGui Headphones. Foldable, 200 g, and it plays from a microSD card or FM radio when you don't want to pair to a phone.
• Best for console voice chat → Crotrain One Ear Headset. Wired means no pairing and no latency, and the adapter set covers PS5, PS4, Xbox and Switch directly.
• Best for hands-free calling on the move → XuanGui Headphones. Bluetooth 5.3 and the built-in HD mic handle voice without a cable.
My Verdict
No — not in the active sense. The spec sheet lists noise control as none. The soft memory-protein foam cushions seal over your ears and reduce background noise passively, which helps in a noisy room, but there's no electronic cancellation.
No. Crotrain states that the earcup and microphone can only be worn on the left ear; the bare side sits above the right ear. This is a fixed design, not a preference you can flip.
The Crotrain One Ear Headset, in my view. It's wired, so there's no pairing or audio delay, and it ships with a 3.5 mm-to-Type-C cable and a Type-C-to-USB adapter to cover consoles, PCs and phones. The XuanGui works over Bluetooth with Bluetooth-capable devices.
No. It's a wired headset with no battery — it draws power from whatever it's plugged into, so it's always ready. The XuanGui needs about 2 hours to charge for roughly 20 hours of Bluetooth playback.
