Bluetooth Receiver and Transmitter, Esinkin Bluetooth 2 in 1 Transmitter Receiver, Wireless Bluetooth Audio Adapter for Stereo System, Headphones, PC, TV, Home & Car Audio with 3.5mm Audio Jack

The device generally works well, for my intended use which is to watch tv late at night without disturbing others. It connects without a fuss, and sound is fairly good, although I found a couple of minor gripes that knock off a star. There's an ever-so-slight lip-sync delay (but looking at reviews of all similar/competing products, this seems to be universal for this technology at this price level, also I’m not sure if my headphones are the right spec to avoid this). The sound breaks up occasionally if you don’t have a direct line of sight or obstacles are in the way, and certainly struggles through walls, otherwise decent range which allows me to go and make a cup of tea and not have to pause my show (my lounge is approx. 6M to the kitchen at the other end). Final gripe is the loudness – it is quiet even when tv volume is turned up quite high, so you need to be careful to turn it back down before disconnecting, to avoid a shock in the morning! However, keeping things in perspective, for just sitting 2-3M away watching tv, it does the job!

Great piece of kit. I use it as I have the Google Pixel 2 so, I have no headphone jack while charging. Turns any headphones you have into bluetooth headphones.It's about the size of half a credit card so would fit even in a ladies pocket no problem. The blue light is a bit bright for no reason, easily solved with a bit of electrical tape.There is one major flaw however, it beeps loudly when the battery is starting to get low. Relentlessly. Once every 10 seconds or so it'll throw in a set of loud beeps and because the beeps don't use up much battery, it'll just keep going and going and going.

Supposed to be AD2P compatible. I want to link with Zik3 AD2P headphone but no way of getting the headphones to handshake they only work as a passive client and so does the Esinkin. I have emailed tech support but I do not think this will do what it says to link with AD2P headphones. Likely to return unless tech support come up with a solution.FURTHER UPDATE:-I now have this unit working. The instructions say that you should enter a Bulutooth code 0000. Trhis is not neccesary withy AS2DP. If the Headphones are set on the app to auto connect it just works. Volume is a little less than I would idaelly like, bu, I think this is likely to be Auto-protection on the Ruak DAB radiuo for Childerens hearing

Once we figured out how to use it with our tv and audio system it was great. Small and effective. Arrived earlier than thought.

Used for turntable output transmission, Easy to Use and sounds great via Bluetooth Bose Speaker - Only 4 stars as 8 metre approx limit .

great but we have to re sync them each time, using two to communicate with each other

I ordered the Bluetooth receiver and it worked perfectly until the battery drained. It then wouldn't recharge with either a mains charger or off USB/laptop. When turning it on, the there is a glimmer of hope as it flashes red for a second, but then it dies. The supplier was good enough to send me a second one FOC, however this one died within a couple of days and won't recharge and is completely dead, so I have either have two duff ones, or they simply don't work. Excellent customer service though.

Works well ,but bass response is poor
