iDIGMALL Bluetooth 5.0 Transmitter Receiver for TV, 2 in 1 Wireless Audio Adapter 40ms Low Latency for PC DVD CD Radio Projector with Digital Optical Aux RCA Jack Dual Link Stream Volume Control

This is a neat little transmitter - the instructions need careful reading, but are relatively clear. It pairs up easily with all the devices I have tried with it.I have only had it a day or two so I can't comment on battery life. As far as I can tell sound quality is good, but I'm hard of hearing so I can't be too certain.I bought it to get Bluetooth audio via the SPDIF outlet on my LG smart TV using a pair of Sennheiser M2 IEBT headphones.Over the SPDIF connection the sound was badly distorted - sounding almost like a helicopter - although using an AUX connection it was fine.I contacted DIGMALL customer support via Amazon and got an amazingly fast response. They took me through various steps to try to resolve the problem and we finally came to the conclusion that there was an issue with the headphones. The transmitter itself worked fine over SPIDF using a Bluetooth soundbar.I eventually got a satisfactory result using a decoder to convert the SPDIF signal to standard audio (3.5mm jack) before passing it to the DIGMALL transmitter AUX IN. I had already had the decoder, so no extra cost was involved.I am really impressed with DIGMALL customer support. They responded in real time and were incredibly helpful. Thanks - five stars from me!

The connection from optical TV fitting to wireless headphones is very useful for me . The very small user guide booklet I found extremely difficult to read

Sound sync can go off at times on the optical haven't tried the audio jack yet but to be honest it could be just a lag during the processing of the Bluetooth signal, I am using the Bluetooth box to transmit audio from my tv to a diy stereo speaker box I built and once I got the Bluetooth box setup correctly it works without any major errors, thankfully my tv has a sync setting on the optical audio setting however after a while for some unknown reason it shuts down the optical, so I have ended up using the audio jack instead and so far it is without fault although some films will have sync issue due to too much processing of the audio in the box

Refusing to pair with my headphones that pair with every other device I have. That was the entire point of getting this adapter so I can use it with the tv that doesn't have Bluetooth and use my headphones. Very dissapointed

Sound quality is good and very easy to operate.

I used out to connect my iPhone to a Bose stereo. The connection with bluetooth was pretty much straightforward.Cons:- bluetooth doesn't reconnect if turned off- there is a high pitch noise when charging- the LED is quite bright at night- buttons have multiple functions, easy to do the wrong thingBut the main problem which I had was the volume. I had to turn up the receiver and the phone top maximum, which means you get very loud phone calls or - when switching to another sound source - loud radio or similar.I sent this device back and bought the SONRU Bluetooth 5.0 Transmitter Receiver which, I find, is a much smarter device.

The item was described as low latency but was totally unsuitable for synchronising with TV audio, out of sync by a number of seconds. Since learnt that bluetooth is only good for remote audio on gaming where the gaming software compensates for out of sync audio. For TV you have to buy more expensive Radio Frequency headphones/transmitter which I did. Audio perfectly in sync and by using the optical connection, volume control on the RF head set is independent of the volume control on the TV remote.

Brilliant product that’s allowed me to stream from my TV to my Bose Companion 3
