How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear Bluetooth headset that keeps your ears free and your surroundings audible during calls, meetings and workouts, choose GREYOLK Open Ear Headphones; if you need a single-ear business earpiece with a charging case that stretches total battery life to 60 hours, choose QZYCY 5.3.
• GREYOLK Open Ear Headphones — biggest strength: an open-ear, air-conduction design with 15mm speakers, an AI noise-cancelling mic on a 270° rotatable boom, Bluetooth 5.4 and a 32g body you can wear all day while still hearing traffic, coworkers or your surroundings.
• GREYOLK Open Ear Headphones — biggest trade-off: it's a two-ear hook-style set with 10 hours of music time and a 2-hour charge, and the multi-function button does not work with desk phones or landlines.
• QZYCY 5.3 — biggest strength: a single in-ear earpiece with dual noise-cancelling mics, smart touch plus physical buttons, and an LED charging case that pushes total power to 60 hours (12 hours talk per charge, 48 more from the case).
• QZYCY 5.3 — biggest trade-off: it's mono, in-ear and sealed, so you lose the environmental awareness of an open design, and it has no active noise cancellation — just the dual-mic call filtering.
• Who each pick is for: GREYOLK for people who want both ears, open-ear awareness and workout-friendly comfort; QZYCY for drivers, road warriors and office multitaskers who want one discreet earpiece and maximum battery.
The GREYOLK Open Ear Headphones are built around one idea: keep your ears open. Instead of plugging your ear canal, the V3 hangs on your ear as an open-ear design with oval earpieces and 15mm drivers, so you get stereo sound while still registering what's happening around you. That matters if you jog near traffic, work in a shared office, or take calls while walking. The AI noise-cancelling microphone sits on a 270° rotatable boom, which means you can angle it toward your mouth rather than hoping a fixed mic catches your voice.
Comfort is the other headline. At 32g, with a skin-friendly, smooth ABS body, this is a set designed to be worn for long stretches rather than pocketed between calls. GREYOLK lists 10 hours of music time and 8 hours of talk time, with a 2-hour charge over USB-C. Bluetooth 5.4 handles the wireless link within a 10-meter range, and the multi-function button covers calls and music with one hand — including switching between two connected devices, which is genuinely handy if you keep a phone and a tablet paired at once.
QZYCY 5.3: Who It's For
The QZYCY 5.3 goes the opposite direction: one ear, maximum uptime. It's a single in-ear earpiece with a hook shape, a 180° rotatable ear hook and a 270° flip-boom arm so you can wear it on the left or right ear and point the mic where you need it. Three sizes of soft ear tips are included, and the skin-friendly TPU+PC finish is meant to stay put without pressure. If you've ever juggled a phone against your shoulder during a call, this is the design that fixes that.
Battery is where it separates itself. A 1.5-hour charge gives 12 hours of continuous talk time, and the portable charging case adds another 48 hours for a total of 60 — with an LED display so you can see the remaining level at a glance. It charges either in the case or over a Type-C cable. For long drives, back-to-back meetings or travel days, that's the kind of headroom that means you stop thinking about charging altogether.
On audio, QZYCY pairs dual high-definition noise-cancelling microphones with dynamic drivers to filter background noise and lift voice clarity — the classic call-first tuning. Controls blend touch and physical buttons: play/pause, volume, track skipping and call management, plus a one-click wake for Siri or Google Assistant. Bluetooth 5.3 handles pairing across iOS, Android and Windows within 10 meters.
Where it falls short: there's no active noise cancellation here, so noisy environments are handled by the mics on the call side rather than by sealing out sound. It's mono, so music listening is a single-ear experience. And at 73g it's a heavier package than the GREYOLK set — though much of that is the charging case. It carries a 1-year manufacturer warranty, one year less than GREYOLK's.
Side-by-Side: Which Should You Choose?
• Best for staying aware of your surroundings → GREYOLK Open Ear Headphones. The open-ear design leaves both ears unblocked, which is the whole point for commuting, running and shared workspaces.
• Best for long calls per charge → QZYCY 5.3. It lists 12 hours of talk time against GREYOLK's 8 hours of talk time.
• Best for stereo music and all-day wear → GREYOLK Open Ear Headphones. Two ears, 15mm drivers and a 32g body make it the more comfortable option for listening and wearing for hours.
• Best for one-ear, hands-free multitasking → QZYCY 5.3. A single earpiece keeps one ear free for the room while the flip-boom mic handles your voice.
• Best for pairing flexibility and newer Bluetooth → GREYOLK Open Ear Headphones. Bluetooth 5.4 and MFB device switching between a phone and tablet is a real convenience.
• Best for cross-platform compatibility → QZYCY 5.3. It's explicitly built for iOS, Android and Windows devices, with Siri and Google Assistant activation.
• Best for drivers and road warriors → QZYCY 5.3. The charging case plus 12-hour talk time is made for days away from a wall outlet.
In my opinion, the GREYOLK Open Ear Headphones are the better buy for most people who want a Bluetooth headset for calls, meetings, driving and workouts — the open-ear design, the 270° boom mic, the 32g weight and Bluetooth 5.4 cover more everyday situations, and the 2-year warranty is the longer one. I'd steer you to the QZYCY 5.3 only if your priority is a single discreet earpiece and you want the charging case's 60-hour total, or if you specifically need 12 hours of talk time per charge. Both are honest tools for different jobs. Check the current price on Amazon before you decide, since that's the one variable a spec sheet can't settle for you.
how to bluetooth headset to pc
Pairing a Bluetooth headset to a PC is a two-step process: put the headset into pairing mode, then open your computer's Bluetooth settings, turn Bluetooth on, and select the headset from the list of available devices. Both the GREYOLK Open Ear Headphones and the QZYCY 5.3 use Bluetooth — 5.4 and 5.3 respectively — and work within a 10-meter range. One note from GREYOLK: if the headset won't connect, confirm your device actually supports Bluetooth.

how to bluetooth headset to ps5
The PS5 supports Bluetooth for some accessories but not as an open pairing target for every headset, so many Bluetooth earpieces need a USB dongle to work with it. The QZYCY 5.3 is listed as compatible with iOS, Android and Windows devices, and the GREYOLK set is a standard Bluetooth 5.4 headset designed for phones, tablets and computers. For PS5 use, plan on a dongle or a wired path rather than assuming a direct pairing.
how long do these headsets last on a charge?
The GREYOLK Open Ear Headphones list 10 hours of music time and 8 hours of talk time, with a 2-hour charge over USB-C. The QZYCY 5.3 lists 12 hours of continuous talk time per charge, plus a charging case that adds 48 more hours for 60 total, with an LED display showing the remaining level. If you're rarely near an outlet, the QZYCY's case is the bigger safety net.
