Tewtross Bluetooth Audio Transmitter Receiver Wireless Connector Adapter for TV, PC, Home Audio with Digital Optical SPDIF TOSLINK 3.5mm Aux RCA Connectivity Compatible with Low Latency Devices

This fantastic device fits comfortably in your palm! Here are some quick pointers: - In TX mode, the OPTICAL output from TV produces excellent audio quality, over a BT v4.2 receiver - Battery charge lasts for approx. one week, with 2-3 hours of daily usage (RX mode). The unit attains full charge in ONE hour. Have not used TX-Optical mode for long, but as per specs the battery life is slightly lesser in TX-Optical mode. - RX-AUX mode works seamlessly on Sennheiser [earphones & headphones]. I have not yet used the TX-AUX mode, hope it works out of the box! - The unit comes with a Qualcomm CSR8670 chipset, with Bluetooth v5.0 as per the enclosed leaflet (see pic attached) - The usage range would be approx 10 metres (without walls) with no audio dropouts whatsoever (walls do cause interference, which is the expected behavior) # IMPORTANT : This device does not have: ** a BUILT-IN MIC (phone calls need to be taken on the phone itself). ** Volume controls and Media control keys This one is a bit expensive for INR 2.4k, but worth the investment! Update August 2025: The unit still works after 4+ years. Will recommend this any day!

Review after one month of usage. Provide a high-quality audio input like Spotify (set to very high-quality streaming) and listen through a premium earbud like BOSE QC II or something similar, the sound is outstanding, for this price point. Long battery life and standby timing. Very easy to operate. Bluetooth audio video sync is good. Looks like worth for the money.

I looked up many Bluetooth Tx/Rx to convert my Altec Lansing speakers and when I saw this, I wondered why so expensive. Ordered and this came before time. Thanks. Amazon. The package had a sticker giving mobile numbers to call in case of difficulty in Setup, and same number for Registration of product for 12 months and additional free 3 months. Open the box and the device sits neatly in a foam cutout. Just the size of three fingers held up. Build quality is Superb. Neat layout of On/Off button on top, Pair button on side, below the On/Off button. The Tx/Rx and SPDIF/Aux select buttons laid on the right side of the device. The connecting Ports with SPDIF RX, SPDIF TX, and the AUX ports are on the rear. Connecting was a breeze. The Altec Lansing speakers played music wirelessly, instantly. One older VU tv could connect to Bluetooth Headphones immediately thru both SPDIF TX as well as the AUX. The new VU Smart tv could not play thru Bose QC 35II Headphones. Need to check settings on tv and try with the SPDIF. Battery back up is very high. 21 hours if connected to SPDIF and 26 hours on AUX. You can put this in your pocket too and take it anywhere to cinject Device at that place. Recommend this highly. Top class product.

Earlier, I tried couple of Aux based Bluetooth transmitter and got fed up with audio quality. I am a reasonable audiophile. I got this Tewtross device connected through the TX port optical interface to my Sony TV, which did not have bluetooth audio. The sound is now great with this transmitter and as good as connecting directly to a TV with bluetooth. Now I am able to enjoy high quality audio on any of my bluetooth headphones from TV ( I am using B&O H4 as primary headphone, so you can understand the audio quality I am talking about) Since it has RX as well, I have connected my old Onkyo receiver (7.1 system) through optical cable to RX port. Now in the familily, we are able to play vey high quality music from any of our mobile phones on our Onkyo 8 speaker system. In a nutsheel, I got my old Onkyo (which is a great system, btw) bluetooth enabled with this device. Battery life is also good and it charges fast. One warning, pls do not plan to use with analogue aux and expect good audio, though it works.

Interesting concept and easy to set up (had paired with my Sony TV), but it was adding lots of static sound and interference to the audio, and crazy volume fluctuations to the point where it hurt the ears. Barely used it.

I was able to connect to my Monitor with Alexa, but when I switched Aux to spdf it won't connect, so I switched back to Aux. But after switching it won't connect back even if we try to pair again. Worked fine with my Senheiser CX 7 headset too, but sadly even if my headset supports SPDIF it won't connect. As of now I'm only able to connect my headset with Aux

One of my best purchase ever. Good product for audiophiles who want to play music wirelessly on their vintage audio equipments. A-grade sound quality(there is still some loss in clarity as compared to wired systems, but you will not notice it until you compare it with a wired input system). It does not require frequent charging. Pairing is hassle free. Reviewed after 6 months of use.

Good bluetooth transmitter and connect easily with 2 headphones. Sound is good. Only problem is that one of the headphones gets disconnected automatically and it has to be paired again in the middle of program we watch. Overall good product as transmitter if you want to use it to connect 2 headphones a t time and watch TV program.
