Review: 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.
Review: 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 :)

### ⭐⭐⭐⭐⭐ Good but needs line of sight over any distance .
*by B***O on 27 July 2025*

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
*by S***R on 28 January 2026*

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
*by S***Y on 14 May 2025*

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!
