• Ugreen USB — biggest strength: Bluetooth 6.0 with EDR and BLE in a plug-and-play dongle that connects up to 5 devices at once on Windows. Biggest trade-off: Windows only — no macOS, Linux, Win 7, consoles, TVs or cars, and any existing Bluetooth adapter in the machine has to be disabled first.
• TECKNET Open Ear Headphones — biggest strength: A genuinely wearable open-ear design: 8 g per earbud, flexible ear hooks, IPX5 water resistance, 40 hours total playtime with the case, and a 36-month warranty. Biggest trade-off: Open-ear means no ear-canal seal, so bass and isolation are naturally limited compared with in-ear buds, and the case is part of the battery story — the buds themselves run about 10 hours per charge.
• Pick Ugreen USB if your problem is a desktop or older laptop that simply can't talk to Bluetooth accessories.
• Pick TECKNET Open Ear Headphones if you already have Bluetooth on your phone or laptop and want earbuds that stay put and let you hear traffic.
• They don't compete. One adds connectivity to a PC; the other is the thing you connect. If you need both, they solve two different problems.
This is a problem-solver, not a gadget. The pitch is simple: your computer either has Bluetooth or it doesn't, and if it doesn't — or if the built-in radio is old and flaky — this 5 g black dongle gives it Bluetooth 6.0 with EDR and BLE. EDR is the part that matters for audio and file transfers; BLE is the part that matters for keyboards, mice and other low-power accessories. Bluetooth 6.0 also works backward with 5.4 and 5.3 devices, so you're not locked into brand-new gear.
The feature I'd actually point a buyer toward is multi-device support. Ugreen says it can hold up to five different types of Bluetooth devices connected at once — mouse, keyboard, phone, headphones and so on — without them fighting each other. There's a sensible caveat in the specs: if you connect two audio devices of the same type (two speakers, or two pairs of headphones), only one can play at a time. That's normal Bluetooth behavior, not a defect, but it's worth knowing before you buy.
Who should buy it: anyone running Windows 11, 10 or 8.1 who wants a dongle that works the moment you plug it in — no driver hunting. It's also a good fit for someone who wants to use a game controller wirelessly, since the specs specifically note it works with controllers even though it won't work plugged into a PS5, Xbox or Switch directly.
TECKNET Open Ear Headphones: Who It's For
These are built around one idea: keep your ears open. Each earbud weighs 8 g, and instead of plugging into your canal they hook over your ear, leaving it unsealed. That's the whole appeal — you hear traffic, announcements, a training partner, a colleague at your desk. For running on a road, cycling, or working in a shared space, that situational awareness is the feature, not a compromise.
The hardware backs up the concept. Flexible ear hooks hold the buds in place through gym sessions, jogging and hikes, and IPX5 means sweat and light rain aren't a death sentence. Inside, 14.2 mm dynamic drivers do the heavy lifting — a large driver for this category, which is how TECKNET gets "rich bass" out of a design that physically can't seal your ear. Reasonable, but don't expect the thump of a good in-ear pair.
Battery is where these get interesting. TECKNET quotes up to 10 hours per charge and up to 40 hours total with the case, which holds three extra full charges. A 10-minute top-up gives you about 2 hours of playback, and there's wireless charging plus a smart LED display that shows remaining power — genuinely useful if you're the type who forgets to charge until the moment you need them. One spec quirk worth flagging: the battery section lists average life at 7 hours while the marketing copy says 10. Real-world numbers sit somewhere in between, and volume is the usual variable.
Connectivity is Bluetooth 6.0 with a stated 10 m (33 ft) range, pairing with phones, tablets and laptops. Calls are handled with touch controls — tap to play, pause, answer or summon a voice assistant. There's no noise cancellation here (the spec sheet says so plainly), and no headphone jack. And the warranty is unusually long at 36 months, which tells you TECKNET expects these to survive the gym bag.
Who should buy them: runners, cyclists, gym-goers, delivery and warehouse workers, and anyone who needs to stay aware of their surroundings. Who should skip them: commuters who want to block out a noisy train, bass lovers, and anyone who prefers the sealed fit of traditional in-ears. One practical note — the specs mention the earbuds may need activating on first use, so read the manual before assuming they're dead.
• Best for fixing a PC with no Bluetooth → Ugreen USB. That's its entire reason to exist.
• Best for running, cycling and outdoor workouts → TECKNET Open Ear Headphones. Ear hooks, IPX5 and open-ear awareness are all aimed at movement.
• Best for battery life → TECKNET Open Ear Headphones. Up to 40 hours total with the case versus a dongle that draws power from your PC.
• Best for multi-device setups on one computer → Ugreen USB. Up to five device types connected simultaneously.
• Best for staying aware of your surroundings → TECKNET Open Ear Headphones. The unsealed design is deliberate.
• Best for long-term coverage → TECKNET Open Ear Headphones. A 36-month warranty is a real commitment.
• Best for Windows-only simplicity → Ugreen USB. Plug and play on Windows 11/10/8.1, nothing to install.
• Best if you use a Mac, Linux or a console → neither as-is. Ugreen doesn't support those systems, and TECKNET's buds pair with phones, tablets and laptops rather than consoles.
• Best value → depends on what you're missing. If your PC has no Bluetooth, Ugreen is the cheaper fix than replacing the machine; if you need workout audio, TECKNET is the one that goes outside with you.
If I had to pick one, I'd pick based on the problem in front of me, and for most people reading a headphone comparison, that problem is audio. I'd buy the TECKNET Open Ear Headphones — in my opinion they're the more useful product for the average buyer, because they work with the phone and laptop you already own and they're built for a specific, real use case: moving around while still hearing the world. The Ugreen USB adapter is excellent at what it does, but it only earns its place if your computer genuinely lacks Bluetooth. If that's your situation, buy the Ugreen and buy it without hesitation. If it isn't, it's a solution to a problem you don't have.
FAQ
No. The specs list noise control as "None." Because the open-ear design doesn't seal the ear canal, you'll hear your surroundings — which is the point for running and cycling, but a downside on a noisy commute.
TECKNET quotes up to 10 hours per charge and up to 40 hours total using the charging case, while the battery spec lists average life at 7 hours. Expect somewhere in that range depending on volume, and a 10-minute charge gives roughly 2 hours of playback.
Yes, and they pair naturally: the Ugreen adapter adds Bluetooth to a Windows PC, and the TECKNET earbuds connect to it as an audio device. Just remember that if you connect two audio devices of the same type through the adapter, only one can play at a time. Compare the current prices on Amazon before deciding which to buy first.
