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.

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! 👌🎧

Initially was working well, but after a few months, suddenly started showing errors and now it's not functioning at all ! No clue of any Service Centre or any way of getting this repaired or replaced ? Truly a BAD Experience 😢

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.

I was looking for a device to connect 2 headphones with my tv so that me n my wife can enjoy Series together without disturbing our kids sleep with noise I m quite impressed with this product built quality is good .. wires are also decent Thr are few things to keep in mind b4 buying this Your Tv should have optical output for better experience .. you also need to change few settings of Tv.. Initial pairing is a task n quite techie.. even I had to call Cust Support They were readily available to help after watching video I was able to connect it properly Sound quality in both headphones is good n audible I would recommend this product

I got this to add-on to a high-end system, which traditionally doesn't have the facility. However it's often requested when guests come over. I was using a Phoenix transreceiver, but the constant need of charging and the single indicator LED made it difficult to integrate into this kind of application. The optical out is connected to a dual ESS9028 DAC, and the device used for transmission is the iPad Air. This lacks a battery, which is a big differentiator. This means it is not exactly portable, and the form factor reinforces that 'feature'. It is intended to be a desktop unit, and it comes with a reasonable set of cables. The quality of the included cables is quite poor, so it's best to use something else. Compared to the direct input from USB, the overall sound is poorer, with a shrunken soundstage and coarse vocals and treble. Still, this is being used in a high-end system - I suspect with many lesser speaker/amp/DACs it will be acceptable. At maximum output, the level is about 1-2dB lower than a direct USB connection to the DAC. It is around the same as my Signature Acoustics unit, which is 1/3rd the size but uses a battery, and doesn't have a volume control or the bypass feature, or the nice display which is handy if you are close by. The bypass is one of the highlights of this device, it basically connects the two optical ports together in passthrough, and allows you to use both BT and another optical source/receiver - though only either can be used at a time. The build quality is average. It is lightweight enough that a set of decent cables will tip it over backwards, hence the thin cables supplied. The onboard volume control is nice, if a bit redundant given everybody uses their handheld or other device to control volume (I use the DAC remote). It also has only 16 clicks, so the control will be very coarse. The display has no spelling errors and while the resolution is low, it is sufficient for the tasks. Overall, it's quite expensive but is more kitted out than similar devices. The sound quality limitations of BT transmission (compulsory resampling and lossy compression, among others) cannot be overcome even with the fanciest devices and protocols, so I'd rank it close to the top of what you can get as an add-on for a hifi system. For more 'normal' usage, there are cheaper options available.
