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-passOverall: 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 Receiver2. Two device can connect at same time3. Sound Quality is goodCons: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 consPros1. 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.Cons1 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 use2 needs continuous power supply, something directly taking power from tv could have been better3 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 adjustment4 price is little on higher side, max 1000rs would be better.

Nice product, good performance.

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 closeby2) 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 time4) 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 distortion5) 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

Amazing product. Works really well. The product had all the required cables and that was really helpful. Highly recommend!

The Device is good though it reduces the sound level if connected through Bluetooth.
