Once set-up, product works beautifully to connect TV wirelessly to receiver (2 units)
I purchased these to connect my television to my receiver/sound system wirelessly. The system performs beautifully now, but it was a bit of a challenge to get working properly, perhaps due to a defective optical cable (not the one supplied, but one I had).Now that it is set up, it performs flawlessly. The delay is NOT bad at all, and easily corrected in-set on the television.A few things to note:1) At first, setting one unit as transmitter on my television, and the other as a receiver (on my stereo receiver), I had some trouble getting them to pair, but I put the units close to each other and this problem was solved.2) I still had no audio signal at my stereo receiver. To try to trace the problem back, I first plugged the transmitter into the RCA jacks on my TV and plugged headphones into the receiver (this worked). Next, I plugged the receiver into my amplifier using the RCA plugs (this worked), then tried with the transmitter hooked to the tv optical out (this worked), and finally got it working via the optical cable to my receiver.NOTE: During this process, at one point I had the transmitter broadcasting DIRECTLY to my receiver’s bluetooth input — this was HORRIBLE, with a completely unacceptable delay, but this was the fault of the STEREO RECEIVER, NOT the fault of the Avantree adapter. Using an Avantree Adapter, there is virtually no delay, and it works perfectly.Moral to the story – if you experience a delay, it is likely to your bluetooth receiving unit delay, and not due to the Avantree products. You can, if you want, purchase a second Avantree unit as a headphone/stereo bluetooth receiving unit, and this will solve your delay problem.A+ for the product. This is exactly what I was looking for!

Works like Magic but one issue
Everything about this product works as Intended. All wires are included in the box for any use case. This would have been a 5 star review instead of a 4 star if changing the volume wasn’t a task. Currently to change the volume you have to manually click the + or – on the box which is connected to the Tv for my case. This means I have to get up and walk up to my tv to change the volume which is annoying. I wish there was a remote of some sort to change the volume.Other than that it works great and connection is strong.If they release a new version with a remote I would definitely prefer that instead !

Item is useless if you use it with a TV
I purchased this to set up two headsets using the optical out. Obviously, everything was connected and hidden behind the TV so it wasn’t an eyesore. I connected it to USB power so it always had power at all times.It worked fine once it was set up but the next day it didn’t work.I had to manually get behind the tv and turn it on again. I did this for three days and is was getting very annoying.On the off hand chance maybe something was set up wrong, I contacted the company to ask about this issue and how I could set it so that it always stayed on and ready to use.After a week of back and forth emails they finally said that the device worked correctly, but that it was not designed to stay on. Essentially, the design of the device was poorly conceived.Their first suggestion was to return it (which I did) and buy their more expensive unit (which I didn’t). Their customer service was poor at best.I purchased another similar device which was actually less expensive than this one and it worked perfectly. It doesn’t shut off in between uses.If you don’t want to have to get up to turn it on every time you want to use the device, then steer clear of getting this one.

We purchased this unit in March 2023 and it worked great, until one day in September 2024, it stopped. Customer service was superb and rushed us a new device – actually an updated version, as this one was no longer manufactured. Janice, in particular, was a great customer service specialist. Very polite and extremely responsive to every email we sent. I highly recommend Avantree for standing behind their warranty, and for producing excellent products.

Correspond bien à la description. Mise en œuvre facile.

L’articolo (Avantree) per il collegamento Bluetooth è arrivato in anticipo sulla data di consegna.Ho un iPad 10ª generazione e questo non ha l’uscita fisica audio per collegarlo ad un impianto voce, o cassa amplificata, poi leggendo i vari post e recensioni, ho scoperto questa scatoletta magica (con uscita audio), che in un attimo si collega al bluetooth del mio iPad e da questa con un cavo entro nel mixer dell’impianto voce, una meraviglia.Le istruzioni in italiano sono comprese.Ciao!
