SPECIFICATIONS COMPARISON TABLE Oasis Plus 2 Avantree Audikast 4 Avantree Audikast 3 Avantree Orbit Pro Review: Excellent unit that has made my LG C3 OLED TV useable with headphones! - Excellent unit that has made my LG C3 OLED TV useable with headphones! Audio is rock solid and plenty loud enough even without the boost option. In fact the boost introduced a bit of distortion at higher volumes, but luckily I don't need it. The remote for the volume is very responsive and I'm very happy with the unit. It's a very clean, pleasant sound with no noise or buzzing. The only slight niggle is that if I pause any streaming service (Prime, YouTube etc.) the audio does start to break up and go out of sync when I resume the programme. This doesn't happen when using Blu-ray or TV recorder playback - it only seems to be when streaming either from the TV's built in apps or via 4K Firestick. A quick power cycle of the unit always restores the audio perfectly though. (I might plug a USB power adapter into smart socket so I can just ask Alexa to power reset it 😊) It's currently getting its' power from one of the TVs USB sockets. I have tested compatibility with: Shokz Open Dots One Soundcore AeroFit2 Sony WF510 Tozo Openbuds Soundcore Sport X10 Cambridge Melomania 1 All were bought over time to try and get a set of headphones working natively with the LG OLED - none worked reliably with it! All the above headphones worked with other devices and now work seamlessly with the Aventree Oasis Plus 2. Highly recommended! Review: Worth the money - Needed something so I could link my DFS Cine sofa to my Samsung TV without the awful loss of sound that Samsung imposes on non Samsung products. This did the trick, it’s easy to setup and links to the sofa via Bluetooth whilst still connected via optical cable to my original surround sound system. I’ve got to turn the sound down on the original surround sound otherwise I get an echo effect. It also incorporates a boost switch that makes the sound go even louder. Bit pricey for what it is but worth the money. ## Features - 【For TVs With Optical / AUX Output】 Connect directly to your TV via Optical (SPDIF) or AUX to stream TV audio wirelessly to Bluetooth headphones or Bluetooth speakers for private TV listening.

So no issues there. There are a couple of things to note, which are not the fault of the device but you should know about before you get disappointed and think you have to return it becuase you might assume the tranmitter is faulty. Check that your headphones have Aptx. I assumed that my Sony noise-cancelling headphones would have it but they don't so there is a small lag issue. It's not enough to notice if you are watching the TV on its own with just the headphones on, everything seems to match up very well and i don't notice any lag in that situation, however if you're watching it with your headphones and other people in the room have the soundbar on, there is a slight echo, the sound comes out of the soundbar before it comes out of your headphones. So you will need noise cancelling on and the volume up to try and mitigate this. Maybe changing my headphones will eliminate the problem completely, but that sounds like an expensive thing to try only to find out that it's got something to do with physics and the speed of sound and it's not a transmitter issue at all. The other thing to take into account is that the signal is very strong. Yesterday I spent ages trying to fix my phone including resetting the bluetooth function and repairing it, because my phone kept dropping the connection to my headphones within seconds. I thought my phone was broken. It turned out that I'd left the transmitter switched on in the living room and despite being in the kitchen, my headphones were dropping the connection to my phone and reconnecting with the transmitter. You can tune out the slight echo once you get used to it, so I'd describe it as more of a niggle rather than an annoyance. So like I say, not exactly faults with the transmitter, but just something you might want to be aware of, all in all it's a great solution for TVs that no longer have a 3.5mm jack for people who want to use headphones. ## Frequently Bought Together - Avantree Oasis Plus 2 - Bluetooth 5.3 Transmitter for TV to Wireless Headphones/Speaker, Compatible with Optical & AUX Output TVs, with Remote Volume Control, aptX-Adaptive, Soundbar Passthrough - KabelDirekt TOSLINK – Optical Audio Cable – 6ft – Fiber Optic Cord, S/PDIF Digital Audio Optical Cable for Soundbar, Stereo Systems, Home Cinema, Xbox One/PS4 – Designed in Germany - Amazon Basics Toslink Digital Optical Audio Cable, Multi-Channel, for Audio System, Sound Bar, Home Theatre, Gold-Plated Connectors, 6 Foot, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/663525867-avantree-oasis-plus-2-bluetooth-transmitter-for-tv-with-remote](https://www.desertcart.be/products/663525867-avantree-oasis-plus-2-bluetooth-transmitter-for-tv-with-remote) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-06-23*
