Bluetooth 5.0 Transmitter Receiver, 2 in 1 Bluetooth Adapter 3.5mm Jack Mini Portable Noise Reduction Bluetooth Transmitter for PC/TV/Car Sound System/Wired Speakers

There was a lot of his but I believe it was caused by the TV. I use two of them and then plug wired earphones for watching TV at night.It works well but the battery life is only around 4hrs compared with the 10 hours advertised.It has quite annoying and loud voice instructions so I used it as a sender rather than a receiver until the battery issue became aparent.A smaller issue is that the light blinks constantly. It's not that bad because it can be turned over though to disguise it.The Trond one is much better with greater battery life of around 15-20hours.

I bought this device to attach to my amplifier so that I can play records through my bluetooth headset. This works well connected to the VCR output via the audio jack input. The instruction leaflet is a little hard to follow, and in fact it turns out to be simple to set up, simpler than it would seem from the instructions! I've only used it in transmitter mode, so can't comment on receiver mode.

Got this to allow use of Bluetooth headphones on an older TV. Easy enough to setup and get working and went without any problems so far. Not sure about battery life as only had itvwas few days but don't think it should be a problem as will only be used for a few hours at a time.Only thing to point out is I had it charging from USB port on the TV while in use but there was a horrible crackling noise. This was fixed by unplugging it from the USB while watching TV with the headphones.

I used this only as transmitter from monitor to wireless headphones.The product itself is small and compact, hides very easily behind my gaming monitor.Audio quality is good too and battery is ok, about 6 hrs.MAIN ISSUE is that there is quite a noticeable latency/lag. Almost one full second of delay.I guess it's not a problem if you're just streaming music/radio, because there is no image.But if you're gaming or watching something it's just very annoying.I will return the item and go for an aux cable extension as I think all Bluetooth transmitterd will have some degree of latency.

Using this in transmitter mode there is about a half-second latency/lag. I bought this to transmit a signal from my guitar via a lag-free audio interface to a lag-free bluetooth loudspeaker. Using it for a guitar input, there is about a half-second delay between plucking a string and hearing the sound rendering it completely useless! I bought it specifically because advertised as 'lag free' and 'low latency'.

This item looked to be good value for money, but having tried it on with a number of different equipment (iphone, ipad, external speaker, airpod pros and dab radio), on both transmit and receive, the sound is barely audible, even turning the volume up to maximum. Unfortunately, this bluetooth receiver/transmitter was useless for my purposes.

Really easy to set up and work right away. Used to connect TV to speakers...

Works ok, using from audio out on a projector to a speaker. paired and connected immediately first time round. Disconnected as I unplugged the speaker and can be a faff to get it to reconnect. Holds a steady connection once set up though. Just a pain if it unpairs.
