If you want a dedicated TV audio transmitter that feeds two pairs of Bluetooth headphones at once and lets you control volume from the couch, choose Avantree Oasis Plus 2; if you need a plug-and-play USB-C dongle to add wireless audio to a PS5, gaming console, or PC, choose Ugreen USB-C.
These two products look like they belong in the same shopping cart, but they solve different problems. One is built around a television with an Optical or AUX output. The other is built around a console or computer with a USB-C port. Get that split right and the decision basically makes itself.
• Avantree Oasis Plus 2 — biggest strength: It connects to a TV over Optical (SPDIF) or 3.5mm AUX, streams to up to two Bluetooth headphones at the same time, and includes both on-device buttons and a remote for volume control.
• Avantree Oasis Plus 2 — biggest trade-off: It is not compatible with HDMI-only TVs, HDMI ARC/eARC, or AV receivers, and it does not support Auracast or hearing aids — so it only fits TVs that actually have an Optical or AUX output.
• Ugreen USB-C — biggest strength: A Qualcomm QCC3086 Bluetooth 6.0 chip with aptX Adaptive, aptX HD, aptX and SBC support, LE Audio with Low Latency and High-Quality modes, plus plug-and-play USB-C connection to PS5, consoles and PCs.
• Ugreen USB-C — biggest trade-off: It is an audio transmitter only — not compatible with mice, keyboards, TVs, cars or microphones — and the advanced LE Audio benefits depend on your headphones supporting LE Audio or LC3.
• Who each pick is for: Avantree Oasis Plus 2 is for TV watching, especially for couples or family members who want private or shared listening at their own volume. Ugreen USB-C is for gamers and desktop users who want low-latency wireless audio from a console or computer.
The Avantree Oasis Plus 2 is a TV-first device, and the spec sheet makes that obvious. Its inputs are Optical (TOSLINK) and 3.5mm AUX, and it streams out over Bluetooth using aptX Adaptive and aptX Low Latency. If your TV has one of those two audio outputs, you plug in, pair your headphones, and you're watching TV privately without running a long cable across the living room.
What I like most about the design is the volume control story. There are buttons on the transmitter itself and an included remote, so you can raise or lower the TV audio without digging into TV menus or getting up. For anyone who has ever handed a remote to a guest and watched them get lost in a settings screen, that's a genuinely thoughtful touch. It also supports two Bluetooth headphones at once, which is the feature that makes this thing interesting for couples — two people, one TV, different comfortable volumes. And Optical passthrough means a soundbar connected over Optical can keep playing while your headphones receive the same audio.
Ugreen USB-C: Who It's For
The Ugreen USB-C adapter is a computer-and-console device. It plugs into a USB-C port on a PS5, gaming console, PC or iMac and adds Bluetooth audio with no drivers required. That "no drivers" part is the whole appeal — you're not installing software, you're not troubleshooting a Windows Bluetooth stack, you just plug in and pair headphones.
Under the hood it runs a Qualcomm QCC3086 Bluetooth 6.0 chip, which is the spec I'd point to for connection stability and fast pairing, including in crowded wireless environments where dropouts normally show up. Codec support is broad: aptX Adaptive, aptX HD, aptX and SBC, so the adapter can match whatever your headphones handle. The LE Audio side adds two selectable modes — Low Latency for gaming and video, High-Quality for music — and Low Latency is the default, which tells you who Ugreen built this for.
Sharing is handled two ways. Classic Bluetooth mode supports dual-device connection, while LE Audio mode supports one-to-many broadcasting for group listening. One caveat from the sheet: aptX HD doesn't support dual-device connection, so you can't stack that codec and two headphones at once. There's also a mode toggle — if your headphones or speaker don't support LE Audio or LC3, you switch to BR (Classic Bluetooth) mode, and LE mode needs LE Audio or LC3 support to pair at all. Auracast works too, but with a specific sequence: connect in Unicast mode first, then switch to Auracast for other devices.
Buy it if you're gaming on a PS5 or console, or you want to add Bluetooth audio to a PC without a fuss. Skip it if you're trying to solve a TV problem — the sheet explicitly rules out TVs, cars, microphones, and data devices like mice and keyboards.
Side-by-Side: Which Should You Choose?
• Best for two people watching together → Avantree Oasis Plus 2. It supports two Bluetooth headphones simultaneously, so each listener gets their own volume.
• Best for keeping a soundbar in the mix → Avantree Oasis Plus 2. Optical passthrough lets a soundbar and headphones play at the same time.
• Best for console and PC gaming → Ugreen USB-C. Plug-and-play USB-C into PS5, consoles, PC or iMac, with Low Latency mode on by default.
• Best for codec flexibility → Ugreen USB-C. aptX Adaptive, aptX HD, aptX and SBC, plus LE Audio with Low Latency and High-Quality modes.
• Best for group or shared listening on a computer → Ugreen USB-C. Dual-device connection in Classic mode and one-to-many broadcasting in LE Audio mode.
• Best for a modern, interference-heavy wireless environment → Ugreen USB-C. The Qualcomm QCC3086 Bluetooth 6.0 chip is aimed at stable connections and fast pairing.
• Deal-breaker to check first: if your TV has no Optical or AUX output, Avantree Oasis Plus 2 won't work; if your headphones lack LE Audio or LC3, Ugreen's LE mode won't pair and you'll need to switch to BR mode.
If I were buying for a living-room TV setup, I'd take the Avantree Oasis Plus 2. The two-headphone support, the remote volume control, and Optical passthrough solve real, everyday problems for couples and families in a way a USB dongle simply can't, provided your TV has Optical or AUX. If my priority were gaming on a PS5 or getting clean wireless audio out of a PC with zero setup, I'd take the Ugreen USB-C and its Bluetooth 6.0 chip and LE Audio modes instead. In my opinion these aren't competitors so much as two different answers — pick the one that matches the port on the device you actually want to listen to.
FAQ
Yes. It's plug-and-play over USB-C with no drivers required, and it's designed for PS5, gaming consoles, PCs and iMacs. Just note it handles Bluetooth audio devices only — not mice, keyboards or other data devices.
Avantree Oasis Plus 2 supports up to two Bluetooth headphones simultaneously for TV audio. Ugreen supports dual-device connection in Classic Bluetooth mode and one-to-many broadcasting in LE Audio mode, though aptX HD does not support dual-device connection.
For Avantree, any Bluetooth headphones should pair for TV listening. For Ugreen, the LE Audio modes require headphones or speakers that support LE Audio or LC3 — otherwise you switch the toggle to BR (Classic Bluetooth) mode.
If you're weighing these two, check the current price on Amazon before deciding — value matters, but the deciding factor here is which port your device has.
