Good but needs line of sight over any distance .
This actually works better and connects quicker than the std Aventree docking/charging station that comes with the headphones. only real problem is it needs line of sight to work well so even at 10 yrds in another room it will not work.

Really good little device
A great little product which was so easy to set up and has helped link my 2 seperate and different soundbars together to give a lovely and full stereo sound in the room. Would definitely recommend. It does exactly what it says on the tin and well worth the price :)

Great functionality and easy to use
It is very small and light, one level off flimsy - although to achieve its goal it only needs a few electronic components which probably drives the lack of requirement for a large solid case. As a rough guide the curl in a wire can lift it off the ground as it recoils. However assuming you are setting it up and leaving it, and get your curls out the cable, then it is awesome. Good solid connection, no disconnects, great sound, easy to setup and works like a treat!

This works with none to minimal lip sync error ❤️
So far so good….this is the third device I’ve tried and so far (it only arrived this morning) it appears to work well and the lip sync seems to be fine. The other 2 devices were from other manufacturers.This is powered from the TV usb port, I had a little difficulty getting the Bluetooth pairing to work with my AirPods but after persisting and several on/off switches the AirPods were working and I could also add my wife’s AirPods too. This is what I have been searching for as I have the AirPods set up as hearing aids, so the TV (without aids) has been too loud for my wife but adjusting to her levels makes it too indistinct for me.I’ll add to this as we progress along but so far it works really well. I’ve also been able to connect a set of Sony Bluetooth headphones and an older pair of AirPods. This is a happy customer experience for me so far 🙏🏻

Excellent item that does what is promised
Amazing product and works a treat. I previously bought a cheap alternative for my elderly Mum and it was useless. I contacted the seller of this item to check TV compatibility prior to buying and received useful information very quickly. I definitely recommend this product.

No English instructions, does not support aptx
Big zero from me, this does NOT connect with their own headphones that supposingly support aptx .And importantly NO ENGLISH instructions!

Latency issues
Latency is the biggest issue with this. For music it’s fine, the sound quality is good. But if you are going to use for watching video, then this is not for your.Set up was very straightforward, didn’t have any issues there. Range and connectivity was great too.Just the sound delay, everything else is great.To summarise, if you’re not using for video then it’s a great buy.

FACIL, RAPIDO, CONEXION ESTABLE ;)
llevo 1 mes con el dispositivo, y muy contento.FINALMENTE SE PUEDEN CONECTAR 2 AURICOLARES A LA VEZ, UNA ALEGRIA !Se instalò en un momento, y de momento no ha dado ningun tipo de fallo.Es mas, es la primera vez que los cascos tienen un alcanze mas lejos de siempre...PERFECTO

接続の安定性が高い
本機をパソコンの3.5ジャックに繋ぎ、bose QuietComfort Ultra Earbudsをペアリングして壁厚300ミリの隣の部屋に移動しても接続が不安定になったり、音が途切れたりすることはありませんでした。また、音ズレは全く気になるレベルではありませんでした。

Świetny
Działa jak powinien, dźwięk super jakości na coxial złączu, nie zrywa, nie zauważyłem opóźnienia w stosunku do wyświetlanego obrazu. W końcu mogę wieczorem oglądać filmy na odpowiedniej głośności, nie przeszkadzając przy tym innym domownikom. Dla starszych TV bez BT rewelacja.

Easy Setup. Good Sound. Great Range
My wife and I have different ideas about what an appropriate volume for watching television is.She has a pair of JBL Bluetooth headphones and I have a pair of VOKALEN Hyper Pros. I like this device because you're free to use what you've got and aren't locked into a brand of headphones you don't like.I split the AUX out of the TV to go to our soundbar and to this device so we can use both.Setup was really as easy as putting the headphones in pairing mode and pressing the button on the device; They find each other easily.The audio is clean and stable and I was a little surprised at the range. I didn't think it would go as far as it does. And the device is smaller than I expected too so it's easy to find a place to put it.
