How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to turn your existing wired gaming setup into a wireless one with near-zero audio lag, choose Ugreen 5.3; if you need lightweight, open-ear earbuds that stay put during runs and let you hear traffic around you, choose Boytond Open Ear Earbuds. These two products share a Bluetooth 5.3 label, but that is where the overlap ends. One is a USB audio transmitter for consoles and computers. The other is a pair of clip-on open-ear earbuds. Comparing them is really a question of what problem you are trying to solve.
• Ugreen 5.3 biggest strength: It adds Bluetooth audio to devices that have no Bluetooth at all — PS5, PS4, Switch, desktop PC, iMac — with no driver installation.
• Ugreen 5.3 biggest trade-off: It is audio-only and needs a source device with a USB port, so it does nothing on its own.
• Boytond Open Ear Earbuds biggest strength: A roughly 5g clip-on open-ear fit plus up to 50 hours of total playback with the charging case.
• Boytond Open Ear Earbuds biggest trade-off: Open-ear design means no noise isolation, and the spec sheet lists no active noise control.
• Buy Ugreen 5.3 if you already own good Bluetooth headphones or speakers and want them to work with your console or PC.
• Buy Boytond Open Ear Earbuds if you want a single self-contained pair of earbuds for running, gym work, commuting and all-day listening.
The Ugreen 5.3 (model CM668) is a USB Bluetooth audio transmitter. Its entire job is to give Bluetooth audio capability to hardware that does not have it. Plug it into the USB port of a PS5, PS4, Switch, desktop or iMac, put your headphones or speakers into pairing mode, and it connects automatically. There is no driver and no software to install. That plug-and-play behavior is the whole appeal: it removes the setup friction that usually makes people give up on wireless audio for consoles.
The spec that matters most here is latency. Ugreen says aptX AD support cuts audio lag to under 60ms, roughly four times shorter than standard Bluetooth at around 220ms. That difference is the reason this adapter exists. On a controller speaker or a TV's built-in Bluetooth, lip-sync and gunfire cues can feel late. At under 60ms, in my opinion that gap becomes effectively unnoticeable for gaming. The adapter also supports aptX HD, aptX and SBC, so it can work with a range of Bluetooth headphones and speakers rather than locking you into one codec.
Who should buy it: anyone with a PS5, PS4, Switch, Mac or Windows desktop who wants to keep using a favorite pair of Bluetooth headphones, especially for late-night gaming or for Zoom, Teams and Meet calls on a PC, where it automatically switches between music and talk modes. Who should skip it: anyone who wants earbuds in the box, anyone who needs Bluetooth for data transfer, and anyone whose device has no USB port to plug into. Also skip it if you need a microphone setup for more than one person at a time.
Boytond Open Ear Earbuds: Who It's For
The Boytond Open Ear Earbuds (model S30i) are a self-contained wireless listening product. They use a clip-on, hook-shaped design that sits outside the ear canal instead of sealing inside it. With a body of roughly 5g per bud, the goal is clear: reduce the plugged-in pressure that makes in-ear models uncomfortable over long sessions. The open fit is meant to carry you through office hours, commutes, travel, walks and longer listening stretches without the tight-seal feeling.
For motion, the flexible clip is the headline. It wraps gently around the ear so the buds hold position without pushing deep into the canal, which is exactly what you want for running, gym work and errands where ordinary buds loosen and need constant re-seating. Boytond describes the sound as bone conduction, and the open-ear structure keeps your ear canal unblocked so nearby sounds — traffic, a training partner, a colleague — still reach you. In my opinion that awareness is the real reason to pick open-ear over in-ear for outdoor activity, not the audio quality itself.
Audio hardware is a 16.3mm dynamic driver, which is a large driver for this category. Boytond positions it as delivering clear stereo detail, defined treble and satisfying bass across music, podcasts, video and calls. I would treat that as a reasonable starting point rather than a promise of premium sound — open-ear designs trade some bass depth for awareness by nature. Battery is the strongest concrete number here: up to 10 hours from the buds and up to 50 hours total with the charging case, plus an LED display so you can check remaining power before heading out. Bluetooth 5.3 handles the wireless connection, controls are touch-based, and the product supports Android devices. The earpiece color is Midnight Black with a black carrying case.
Who should buy it: runners, gym-goers, cyclists, commuters and anyone who wears earbuds for hours and hates the sealed-in feeling. Who should skip it: anyone who wants noise cancellation or deep isolation on a plane or a loud train — the spec sheet lists no noise control at all — and anyone who needs iOS-specific confirmation, since the listed support is Android.
• Best for console gaming without lag → Ugreen 5.3. Under 60ms with aptX AD versus roughly 220ms standard Bluetooth.
• Best for running and gym sessions → Boytond Open Ear Earbuds. Clip-on hook fit plus a roughly 5g body built to stay put.
• Best for all-day battery → Boytond Open Ear Earbuds. Up to 10 hours per charge and up to 50 hours with the case.
• Best for PC and Mac calls → Ugreen 5.3. Works with Skype, Zoom, Teams and Meet, and auto-switches between music and talk modes on Windows.
• Best for staying aware of your surroundings → Boytond Open Ear Earbuds. Open-ear design keeps the canal unblocked.
• Best for reusing headphones you already love → Ugreen 5.3. It turns any Bluetooth headset or speaker into a console-ready one.
• Best for commuting and travel with one product in your bag → Boytond Open Ear Earbuds. Nothing else required; Ugreen needs a host device.
• Best for a wired mic option on a controller → Ugreen 5.3. The included 3.5mm microphone plugs into a controller, dock or PC jack.
If I had to pick one, I would buy the Ugreen 5.3 — but only because my main use case is gaming on a PS5 and a desktop with headphones I already own. The under-60ms aptX AD latency and true plug-and-play setup solve a specific, annoying problem, and nothing about the design asks me to learn anything new. That said, I would not recommend it to someone who wants earbuds, because it is not earbuds — it is a bridge. If your goal is running, the gym, commuting or simply wearing something comfortable for ten hours straight, I would buy the Boytond Open Ear Earbuds instead. Two different jobs, two different answers. Check the current price on Amazon for whichever one matches the job you actually have.
No. Ugreen 5.3 is a USB Bluetooth audio transmitter that adds wireless audio to a PS5, PS4, Switch, PC or Mac. Boytond Open Ear Earbuds are the actual earbuds you listen through. You can even use them together.
The spec sheet lists noise control as none. The open-ear design deliberately keeps your ear canal unblocked so you can hear your surroundings. That is a safety and comfort feature for running and commuting, but it means no isolation in loud places.
Yes. Ugreen states it works for work-from-home calls and meetings on Skype, Zoom, Teams and Meet, and that it automatically switches between music and talk modes on a Windows PC.
The Boytond Open Ear Earbuds, in my opinion. The clip-on hook fit, roughly 5g weight and open-ear awareness are all built for movement and for hearing what is around you. Ugreen 5.3 is a stationary adapter for a console or computer.
