If you want a wireless, single-ear open-ear headset for all-day calls and music with up to 15 hours of talk time, choose BQXX Open Ear; if you need a wired, USB-C open-ear pair that plugs straight into your phone, tablet or laptop and works with no charging or pairing at all, choose COOYA USB C Open.
• BQXX Open Ear — biggest strength: Truly wireless Bluetooth with up to 15 hours of continuous talk/music time and a 1-hour quick charge, plus touch control and active noise cancellation on the mic side.
• BQXX Open Ear — biggest trade-off: It's a single earpiece that only fits the left ear, so you never get stereo sound and it can't be worn on the right side.
• COOYA USB C Open — biggest strength: Plug-and-play USB-C wired connection that works with almost any modern phone, tablet or laptop, with no battery to charge and no pairing to manage.
• COOYA USB C Open — biggest trade-off: It's wired, has no active noise cancellation, and needs a USB-C audio port — so older iPhones with Lightning and any device without USB-C are out.
• Who each pick is for: Choose BQXX Open Ear if you take a lot of calls and want a cable-free left-ear headset. Choose COOYA USB C Open if you want a simple wired pair for commuting, gaming, studying or travel on USB-C gear.
The BQXX Open Ear is built around one job: keeping your left ear free while you stay on calls. It's a single ear-hook earpiece that sits on the ear rather than inside it, so your ear canal stays open and you can still hear traffic, coworkers or your surroundings. That open design is the whole point — it's comfortable and very light, and the hook shape is meant for painless, all-day wear. Just be clear on the constraint: this is a left-ear-only headset. There's no right-ear version in the box, and no stereo pair.
What stands out in the specs is the battery. BQXX rates it at up to 15 hours of continuous answering and music playback, with a 1-hour quick charge. For anyone who lives on the phone — delivery drivers, salespeople, support staff, warehouse and front-desk workers — that's the number that matters, because it means you're not hunting for a charger mid-shift. The controls are touch-based with a single fingerprint-style button, so you tap rather than press. It connects over Bluetooth with a 10-meter range, and it's a lightweight 20 g plastic build in black with a 140 ohm dynamic driver.
On audio, BQXX describes an upgraded speaker with noise cancellation to clean up the mic side of calls. Treat that as call-clarity help, not isolation — an open-ear design physically can't seal off the world. Two practical quirks worth knowing before you buy: you switch between Chinese and English voice prompts by double-clicking the power button while not connected, and power is a 3-second long press on, 5-second long press off.
Buy it if you want a wireless left-ear headset for long call days and you value battery life over stereo sound. Skip it if you need two earbuds, right-ear fit, or wired reliability with zero charging.
The COOYA USB C Open takes the opposite approach: it does away with batteries and Bluetooth entirely and runs on a USB-C cable. Plug it in and it works — no pairing, no charging, no "low battery" mid-call. The specs list it as plug-and-play with the vast majority of USB-C devices: recent iPhones, Samsung Galaxy phones, iPads, MacBooks, Surface tablets, OnePlus, Pixel, Motorola and more. If your device has a USB-C audio port, this is about as frictionless as audio gets.
It's also an open-ear design with a rotatable silicone earhook, which lets you angle the earpiece for a more stable, comfortable fit — and COOYA specifically calls out small ears as a good match. Because it's wired and open, it's a natural fit for running, gym work, gaming, studying, travel and even sleeping, where you want to hear what's going on around you. The 15 mm dynamic driver with a 32 ohm impedance, 105 dB sensitivity and 20 Hz–20,000 Hz range covers the full audible spectrum — and note that impedance figure: at 32 ohms it's an easy load, which is exactly what you want from a wired set driven by a phone or laptop.
Controls are on the cable: an in-line module with a built-in microphone and buttons for play/pause, track skip, answer/end and volume. COOYA also throws in a small clip to hold the mic in place during calls, plus a zipper carrying case to keep it protected from scratches, moisture and dust. The trade-offs are honest ones: it's wired, so you're tethered to your device; there's no noise cancellation; and it needs USB-C specifically. MacBook users also need to manually select the USB device under Sound settings to route audio correctly.
Buy it if you want zero-charge, zero-pairing simplicity with a mic and volume control on USB-C gear, or you have small ears and struggle with fit. Skip it if you're on Lightning-only hardware, want wireless freedom, or need active noise cancellation.
• Best for battery life and wireless freedom → BQXX Open Ear (up to 15 hours, 1-hour charge, Bluetooth, 10 m range).
• Best for all-day call handling → BQXX Open Ear, thanks to the touch single-button control and long talk time.
• Best for zero-hassle setup → COOYA USB C Open — plug and play, nothing to charge or pair.
• Best for stereo or two-ear listening → COOYA USB C Open (it's a wired open-ear pair; the BQXX is left-ear-only and mono).
• Best for small ears and fit adjustment → COOYA USB C Open, with its rotatable silicone earhook.
• Best for commuting, gaming, studying and travel → COOYA USB C Open, given the wide USB-C compatibility and included case.
• Best for right-ear users → COOYA USB C Open — the BQXX simply can't go on your right ear.
• Best for people who hate cables → BQXX Open Ear, full stop.
If I had to pick one, I'd buy the COOYA USB C Open — in my opinion it's the more flexible, lower-maintenance choice. It works across phones, tablets and laptops, needs no charging or pairing, fits either ear with an adjustable hook, and comes with a mic, in-line volume control and a case. That said, the BQXX Open Ear is the smarter buy for one specific person: the heavy phone user who wants a wireless left-ear headset and prioritizes up to 15 hours of talk time. If battery life and going cable-free matter more to you than stereo sound, go BQXX. Everyone else, go COOYA.
No. It's a single left-ear earpiece, so you get mono audio on the left side only. If you want sound in both ears, the COOYA USB C Open is the better fit.
Do I need to charge the COOYA USB C Open?
The COOYA USB C Open lists broad USB-C compatibility across recent iPhones, Samsung, iPads, MacBooks, Surface, OnePlus, Pixel and more — but it requires a USB-C audio port. The BQXX Open Ear connects to anything with Bluetooth, but only fits the left ear.
Match it to your habits: pick BQXX for wireless, long-call days on your left ear; pick COOYA for wired simplicity, stereo listening and small-ear comfort. Since both change over time, check the current price on Amazon before you decide.
