Review: i wanted to make my 2 desertcart 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.
Review: 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.

I’ve been using the Cubetek Bluetooth Transmitter/Receiver, and it’s working absolutely great! We both connect our Bluetooth headphones simultaneously and watch TV together—there are no voice lags or delays at all. The audio sync is perfect, making it feel just like listening directly from the TV. Setup was super easy, and the connection remains stable throughout. It’s a must-have for couples or families who want to enjoy shows or movies without disturbing others, especially when you have a baby or need a quiet environment. Highly recommended for seamless dual headphone streaming! 👌🎧
