Customers say
Customers find the Bluetooth adapter easy to use and set up, and consider it good value for money as it works perfectly for a fraction of the price. The connectivity and functionality receive mixed feedback – while devices pair without issues, some report it won’t connect, and though it works well initially, some units stopped working after a week. Sound quality and build quality also get mixed reviews, with some praising the sound while others complain about terrible background static and poor construction. Battery life and durability are concerns, with reports of units breaking right away and aux connectors failing after a week of use.

It was just as advertised and works like it should. My iPhone connected to it no problem , definitely good value for money.

Works better than I expected.
For a an inexpensive piece of equipment this thing worked rather well. It took a bit of adjusting, moving the unit around within the plug in, but reach out to a good 25 to 30 ft.
Riley Farrand –
Broke.
It broke immediately. The Bluetooth somehow still works though very in an out sometimes. The little piece that goes into the aux broke out of the little dongle that attaches it to the adapter.

Works Almost Perfectly
For what it is, and the price, itâs perfect for what I needed it for (making my personal stereo Bluetooth). However, it took a really long time to get it to connect to my AirPods Pro 2nd Gen. At first connection, the audio was barely audible and you could only hear a little bit of it when you cranked up the volume all the way. Turns out that you have to connect it a whole bunch of times while trying different methods to get it to work. NOTE: This thing connected almost instantly to all other Bluetooth headphones and the first gen non pro AirPods and had no issues with volume. The range on this thing isnât too bad, was able to walk around to different rooms (on one floor mind you) and it didnât lose signal or cut out. The only complaint i have about this is that there is a quite annoying digital signal being produced by the transmitter itself that can be heard during quiet or silent parts through headphones and speakers. Other than that, this thing does have pretty good sound quality for the price, but the digital signal sound can be solved if using a longer aux cord instead of the one supplied. ALSO! When receiving Bluetooth signal (not transmitting) there is no digital signal sound, and it is very quiet and sounds great! If your getting this for a transmitter, maybe get something a little more quality based, but if you donât mind the odd digital sound during quiet and silent parts, then it will most likely be fine.

Michael Copeland –
Great product for the price
Works great with fairly decent battery life. I haven’t tested the transmitter function. But I have been more than satisfied with the receiver.

Kinda a good deal
I thought this was a deal… It’s kinda cheaply made… If you can adjust the sound quality on yr stero or speaker then buy it… If not then it’s not worth it
