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.

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.

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!

Great piece of equipment
Got it to link my inexpensive headphones to my Tv. I'm not very technical but it took less than 5mins to install and the sound is excellent .It's small so doesn't take any space up and you don't see it!

Rip-off
When I purchased this item there was nothing to say that I'd have to subscribe to something that charges me £40 in order to use this I think it's absolutely disgusting. Walsh trying to set it up it said I had to scan a QR code which led me to a site where I had to put in my card details in order for them to take 40 pound a month in order to use it.

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 🙏🏻

Five star performance but see *important note* in review.
I use a bluetooth transmitter to listen on Apple Airbuds to a Sony TV. This Avantree Audikast 3 was purchased to replace an older 1Mii B03 Bluetooth 5.0 Transmitter Receiver that had never worked very well. Whereas the sound from the 1Mii often dropped out and had recently become unusable, this little Avantree unit, one quarter the size of the older 1Mii, gives crystal clear sound and is an excellent buy. I love the way that all the instructions are accessed via QR codes on the unit and paper instruction insert. Cables for USB power optical and 3.5mm audio connections are included so it's ready to go.***Important note: We almost returned it as not working as no light could be seen to suggest that it was working - We'd not realized that the top was completely covered with an opaque label so once removed, it was revealed in all its glory***
