Bluetooth TX and RX not recognised by Sony Bravia 7500E 4k tv. But could connect this device from TV's optical and audio cable to my 32 years old sony music system thro Logitech BT receiver (attached to music system). Device successfully transmitted the TV audio to sony music system. Optical connectivity with TV functioned superbly. Enjoying movie sounds thoroughly in my old music system. Overall it is a good product except it takes time to connect with other device in transmission mode. Functions well in receiving mode with Onkyo Home theatre, mobile, macbook air etc.,

Very simple yet efficient product. I recommend to go for this ... It's multi function multiple input options. Overall it's great product.. I bought twice thus same product .. I have used one as transmitter on my TV for sound and second one on my old Sony amp to receive BR signal .. good frequency response, very low battery consumption and good range 5 M plus

The device is absolutely fine both as transmitter and receiver. There is a considerable delay in the signal received by the speaker when which is used as transmitter. As transmitter to the TV 1. I am using Airtel HD DTH and use the optical out of the DTH box and connect it to spdif in of the device. 2. Altered the audio settings of the DTH to have 80 milliseconds delay in sound over HDMI to bring it in sync with the optical signal received by Bluetooth speaker In general Every audio device apparently will have audio delay settings which can be used and setup to avoid the delay in transmission.

Works well. Easy paring with my sound bar. No lag in sound. Rating is given as 3 star due to the price. Its is only worth for 1500rs as its only capable on audio transmission

I already had a Logitech bluetooth reciever and it was working great till I knew what more could I expect from a tiny bluetooth reciever (and transmitter). The hunt began when I felt a need for a battery powered bluetooth reciever for using with my existing wired headsets. I'm not a big fan of cheap BT headsets, as to bring the cost down, the manufacturer has to use cheaper drivers, which doesn't help. I came to know about this device while searching for portable bluetooth adapters in Amazon India and figured out a bit about aptX. I also came to know that this device could be used as a BT transmitter as well and could input or output using TOSLINK for both TX/RX modes. Though I was not sure of the manufaturer or reliablility per sé, but the device has been great so far for 6 months now being used almost daily for 2 to 3 hours. Battery backup is more than 10hrs for both aux and TOSLINK outputs. Overall very satisfied with the performance. Thinking of buying one more for use in TX mode with my TV/PC.

Its a Made in China product. The article received does not seems to be looking new and had scratches. On contacting seller he informed that the product is further sold as is received by him. On the performance after several attempt it does connected with other Bluetooth devices however the quality of sound is terrible with lot of disturbance. The quality further depletes on connecting two devices at a time. Overall the the article seems to be a copy of original product, may be. Looking at the actual product received Rs.2599 is quite expensive.

I ordered this to to enable my TV with Bluetooth so that I can use a bluetooth headphone to watch TV. My LG Smart TV has only an optical (toslink) output and no headphone jack. I also wanted an option of connecting to the RCA out of my TataSky HD+ set top box. I found the Cubetek Bluetooth Transmitter/Receiver meeting my requirements with the following facilities 1. Can support both Optical input as well as Aux input with a switch 2. Can function as both a transmitter (that is what was required for my need) and receiver 3. Has a battery inside and when charged can function for around 5 hours. Hence easily portable. However I have connected a USB charging cable through my TV's USB port 4. Pairing with headphone was quite effortless 5. The product came complete with all necessary cables (USB charging cable, Aux input cable, RCA to 3.5mm female cable, Optical Toslink Cable) Why only 4 Stars then - A couple of improvements can make it five stars 1. The over finish can be better. The silver body looks a bit cheap plastic and the rubberised bottom bearing the brand name and specs was not affixed properly within the grove. 2. The pricing is a bit on the higher side. For the functionality provided, a 1500 to 1800/- price point would have been ideal. Same product with different brand name are available at 20% lower prices.
