Bluetooth 5.0 Transmitter Receiver Adapter Audio 3 in 1 Bluetooth Audio Adapter 3.5mm AUX RCA Optical USB HiFi Stereo Music, FCC Pass 2A4RO-M6

I used this to connect to my Radioshack Karaoke speaker, and it worked like a charm. Almost a year later, it was having some connection issues with the Bluetooth, so I contacted the seller.The seller immediately sent me a BRAND NEW unit and I am back in business.Pros-Great Unit-Bluetooth connection with NO audio lag (latency), especially important for Karaoke!-Line or Optical option-Built-in battery so you can charge it and use it without a power source!

The media could not be loaded. Bought this to give better sound from a TV in a motorhome. Sometimes it's really hard to hear the TV through the TV speakers if the air conditioning is on. So I bought this and connected an optical cable to it. The transmits over FM radio so then you can just have it go through the car stereo. Also has the option to transmit via Bluetooth to a Bluetooth speaker that you can put right behind your head so you don't wake up anybody else. It's pretty fantastic once you get to figure out how to use it it could be a little complicated.

TIP: The M6 would not pair to my head phones until I turned off the bluetooth in other devices, or turned the devices off completely. Had this just for one day, but it worked fine in transmitter mode through the optical input after finally pairing my headphones.

I bought this to pair with my HyperX Cloud Alpha Wireless head set. The head set uses a usb stick to connect to devices instead of Bluetooth, so I bought this as a way of giving it Bluetooth access to my devices. The thumb stick and headphones say they are connected, and the Bluetooth transmitter says it's connected (I've tested it both on my android phone and on my PS Vita) but there is no audio actually being transmitted to my headphones. Either there's a very specific way to fix this problem, or the product does not work as I had expected when I purchased it. I'm willing to change my review if someone can talk me through a solution to this problem, but if the device cannot transmit true Bluetooth it's sort of pointless to me.

Easy set up, Bluetooth range is great can now control garage stereo from deck, also just used an old phone without Sim as an mp3 player, just load all your music on it then find a player app and off you go. Sound quality good.

I bought it so I could listen to the TV when wife is sleeping i tried every way possible and wold not send audio to my headphones clearly illegible in any combination disappointing. It looked really cool. I thought I'd make my tv bluetooth, or at least the audio but ended up buying a tv that already has it in it.

I got this little gadget so I can avoid hanging wires from my wall-mount TV to my amp. I connected it to the TV optical output, set it on Bluetooth and then go to my amp and made the Bluetooth connect there. I was skeptical but it works better than I expected. There is a perceivable delay in sound from the TV to the amp - may 1/2 sec - livable delay IMHO

Size is perfectWorks very well with my stereo system
