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!

Excellent
This setup functions flawlessly with my Xgimi Elfin projector via AUX and JBL Link portable dual Bluetooth speakers, exhibiting no lag and maintaining perfect synchronization.

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***

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.

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!

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.
