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

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

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.

Grate product, decent sound quality,easy to connect,

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.

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

This Cubetek is a massive convenience upgrade over my old ₹229 STRiff adapter, but don't expect a night-and-day difference in audio quality. For ₹1,899, the sound is very "okay-ish" and lacks some depth. It works perfectly with my old Sony DAV-TZ215 via RCA and has zero lag, making it a great budget fix. However, I’d highly recommend looking at the Ugreen, FiiO for noticeably cleaner sound.

Excellent quality, premium sound output, 0 lag

Bought for Sony Bravia as it was not connecting to airpods or airdopes Bluetooth headphones. Product is good as works as expected. RCA cable did not work for me. Optical cable worked and it allows us to have sound both from TV and Bluetooth headphones simultaneously. Very slight delay, say 0.25 second...so while watching TV, you can feel slight delay between on screen character's lip movement and sound in ear. It's manageable and will need some time to adjust.
