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

Excellent product. Seamless connection and serves the purpose completely. I used as a bluetooth receiver for my very old sony sound system using optical cable.

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 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.

Great product, it solved my late night Movie time.

Been using it since 2 years and the product still works as mentioned. However read below for the reasons why I rate 1-star. It can transmit to two bluetooth devices at the same time. We use it attached to the TV to transmit TV's sound to the Soundbar/2.1 Speaker and the other for a TWS/Wireless earphone. The biggest and most annoying negatives are: 1) It keeps searching, searching.... even if the bluetooth devices are closeby 2) Doesn't auto-connect. For a device to which it connects everyday, we have to go to it, manually search it and then click the knob to connect. Why so many steps? 3) For 2nd device to be connected, it can't find and pair the device easily, takes very long time 4) When we connect it via power adapter/charger via USB, there is distortion which passes down to the listener so we have to keep the power source separate and far away from the TV or Soundbar's power panel to avoid distortion 5) Volume is too low and limited. Even though there's an amplifier in it, there's hardly any amplification and for many devices, the knob on Cubetek controls the speaker's volume too which is very annoying
