Cubetek 3 in 1 LCD Display V5.0 Bluetooth Transmitter Receiver, Bypass Audio Adapter with Aux, Optical, Dual Link Support for TV, Home Stereo, PC, Headphones, Speakers, Model: CB-BT27

i wanted to make my 2 amazon echo dots , diiferent generations to work with the firestick and did the job well. It has Transmitter Receiver, Bypass Audio Adapter with Aux, Optical, Dual Link Support. i use it with my old creative speaker also from the monitor via bypass and now that old speaker can be play from my phone also. I didnot notice any noises , i love hearing songs and some vedios , no lags great buy for me . Bluetooth connectivity is also good.No battery , needs source of charge ,i use the usb 2 extedner from laptop to power it. Great value for money for me .I was surprised many retured it, got a suggestion like so while buying , i am happy with the product.

Update: Tx Config: Using it to transmit audio to headphones., using AUX-in - working fine but need a good quality aux cable. the provided cable is not of good quality - there is bit of audio distortion if u set the volume to max. - the transmitter is bit noisy, when there is no audio playing. but once the audio is fed, the noise goes away (more like suppressed). - some headphones reconnect automatically and some needs to be paired almost every time. Not tested following config: Tx with Optic, Rx with AUX, Rx with Optic, by-pass Overall: good product, perfect for my use-case. Just buy a quality aux cable.

It's a outstanding product. Pros: 1. Can be used as Transmitter and Receiver 2. Two device can connect at same time 3. Sound Quality is good Cons: 1. It should should turn off automatically when there is no device connected

Its been a month that i am using it, here are pros and cons Pros 1. Connects two bluetooth device at a time, which was my main requirement. Easy application. 2 provides all the required accessories with it to connect to tv or any other device, aux cable, optical cable, which is not seen these days while buying other electronic product. Cons 1 connection with two bluetooth devices is an major issue, doesn’t easily detects the devices, i have to make multiple attempts to get the headset detected by the device. But once connected both the head set are good to use 2 needs continuous power supply, something directly taking power from tv could have been better 3 if i have to change the volume, i have to get up and change it where this device is connected, a remote could have been a good solution. If changing volume from one head set then other device connected is also changing, you have to match with the other guys for volume adjustment 4 price is little on higher side, max 1000rs would be better.

Nice product, good performance.
