    Plug & Play

    No Audio Delay

    Bluetooth Audio Adapter Set

    Our Bluetooth audio adapter set includes one Bluetooth transmitter and one receiver to Bluetooth-enable the audio signal from your Non-Bluetooth devices, e,g, TV, PC, AV Receiver, to extend your Bluetooth reach throughout your home.

    No tech knowledge needed! Simply power on the TX and RX unit, they will automatically connect to each other, without having to manually pair them.

Featuring aptX- low latency, both our transmitter and receiver units reduce the delay to non-detectable levels so you can enjoy video wirelessly without sync delay.

    My experience wasn't that great with the product! (UPDATED)
    4 Stars
    My experience wasn't that great with the product! (UPDATED)
    I recently restored a 1980's CD jukebox and I purchased these so that I could split the signal going into the amp of the Jukebox off and send it to my stereo system. The stereo system is roughly 20 ft away from the jukebox and I thought this would be a good way to fill my entire basement with sound. I had tried other Bluetooth transmitters and receivers, but due to the delays introduced in Bluetooth the sound going to the receiver was really out of sync with the source and sounded terrible. After reading reviews and researching the APTX Low Latency Bluetooth protocol I thought this was the solution. In the end however, I was disappointed with this product, and here is why... I'm a huge believer in the Amazon review system, so with so many positive reviews on this product I may have received a bad unit of accessory cable-- I'm really not sure. I had a really difficult time getting the units to pair, and once I did simply moving the receiver unit would cause it to intermittently loose the connection to the transmitter. I tried swapping cables but the problem persisted with the same unit dropping so I feel that maybe the audio jack was bad inside the unit. Additionally, when it was working the sound wasn't that great, even with both units indicating they were in APTX LL mode, both my wife and I could definitely hear a delay in the sound coming from the jukebox and stereo system. So, I'm not sure, but I believe whatever was causing thre issue with the dropped signal was also affecting these from going into the low latency mode correctly as well. I will most likey be sending these back, and since this is my second failed attempt at trying to make a Bluetooth solution work for my project I think I'm finished and may look for a different solution. Like I said, with so many good reviews, my experience my be an outlier.----------------------------------------------UPDATE 8-1-17---------------------------------------------I was contacted by the seller after posting my review with a steps on how to reset both units, with hopes this would fix the issues I was experiencing. I tried the suggested steps but my problem still remained. The seller also offered to ship me a new product (the "Lock" model) that comes pre-paired, you simply turn them on and they are ready to go-- no user pairing required. I will update my review and post my experience with the new product once I receive them, but thus far Avantree customer service seem very proactive and concerned about their customer's experiences with their products-- always a good sign.--------------------------------------------------UPDATE 8-16-17------------------------------------------------I received a new pair of the Advantree Lock ATPx LL from Avantree to replace my defective pair. The main difference between the original product and the new Lock series is that the latter comes with a prepaired set...one dedicated transmitter and another dedicated receiver unit. This seem to cut out all the issue with geting the set to pair. I simply took these out of the box, charged them overnight and then power each on and connected to my devices. All went soomth and no issue with the signal cutting out, no noticiable delay in the transmit and received signal and the paring seems to consistenaly work even when powering them off on on multiple times. I must say that this replacemnet pair seems to work as I would have expected and that I had to had received a defective set the first time around. With this in mind I raised my review from 2 to 4 stars. Again, I can't say enough about Avantree's support... they are very proactive about trying to resolve issues and seem very responsive to questions I've asked, typically responding in 12 hrs or less.
