Bluetooth 4.1 Transmitter and Receiver, Acekool 2-In-1 Wireless Bluetooth Adapter with 3.5mm Stereo Output, (aptX Low Latence,For Sound System,Headphone, Speakers, TV and More)

Firstly, this does everything that I wanted it to do when I purchased it!I bought it for two reasons (other than it being Bluetooth 4.1, which I have found to give the best distance, easiest connection and longest battery life:1. Attach it to transmit from my TV to my Bluetooth head phones and also to my games chair.2. Receive Bluetooth audio from my phone to play through the AUX socket in my car. Although my car has Bluetooth for calls, you cannot transmit audio (music) to it so this is perfect, saves having to connect it to the car with a cable and all the hassle that that bringsIn saying that, I'm sure I will end up using it on all sorts of other devices as well, such as my HiFi unitEasy to set up (although you may have to switch it to 'receive' so that it can find your phone. Just like any other Bluetooth device, you put it into pairing mode and away you go. The first time I turned it on, because it wasn't paired with any device it went into pairing mode automatically. once connected you get a constant blue light to show success.When fully charged, it says that you have about 10 hours transmission, which is fine for the car, I cant see any journey being longer than that. When it is connected to my TV, I can have it permanently charging from one of the USB outlets on it. You can use any Micro USB cable but it does come supplied with one though.It's smaller than I thought it would be which is a good thing, you can see the size of it in my hand.Just about the only thing you need to remember to do is switch to transmit or receive. This really has solved a lot of problems for me and I'm glad I bought it.

Beware! this unit only offers low latency in Transmitter mode. At least that's what Acekool tell me and I suspect they are correct.Purchased two as a TX - RX pair. Units link up ok and sound pretty good but I measured 200ms latency which is useless for my application. Looking for a low latency RX to test this out now :-)

Well designed generic alternative to mainstream products. A Feature packed item at a competitive price; does what it says in the description. Only "Con" is the translation of the user guide into English, but anyone familiar with Bluetooth devices should have no problem using it to its full potential.

I THOUGHT IT WAS VERY GOOD THEN AFTER AROUND HALF A DAY IT JUST STOPPED WORKING SO HAD TO RETURN IT, A SHAME STILL THATS LIFE

appears to be quite low latency and the ability to use as a transmitter or receiver is a big bonus in being able to test the bluetooth system

Nice little box of technology that can transform your regular sound system into a Bluetooth receiving or transmitting audio system. I use this on my car to facilitate audio streaming from my phone as I only have an aux in socket. I've connected it in such a way that it is permanently plugged in to a USB charger so I don't have to remember to recharge it or worry about it not working. In the way that I'm using it, it works really well, with a few minor gripes. You can't pair more than one device to it simultaneously. When my daughters are in the car, they insist in taking over the playlist, but each time, the pairing process has to be undertaken to facilitate this. And then I need to re-pair my own phone once they are not in the car in order to enjoy my own (better!) music. The other tiny gripe is that each time the car is started, you need to manually power up the box, which is a 3 second push of the power button. For me personally, I would have liked an auto-power up once a powered USB connection is detected. Just means I have to pull up the centre console, turn the box on and put the armrest back down each time I stop and start the car. I bought this box because I'm too lazy to fiddle with the aux wire each time I want to listen to music. instead I'm fiddling with an armrest and button. Granted it looks tidier, phone can stay hidden and no wires on show, but it's still a minor inconvenience to get music playing from your device.

Quite honestly, this is utter rubbish and I advise against buying it especially at the price of writing £25.99. I got it at a discount and it was not worth that price either and I returned it.I will say that when it does connect there is no delay in sound. I tried it through my television with a terrestrial program, film on a USB drive and also a recording on the harddrive for the television. I also put my phone through my stereo via it and it worked witout any problems. However, the problems arise trying to pair it. Even though the instruction manual has an English section it seems like a direct translation from Chinese and just does not make sense. And it needs to because the unit is all based around one small LED light which flashes red and blue and stays on and goes off and really is not suitable for such a device which purports to take up to 4 devices. I struggled to get 2 to register simultaneously so how 4 work I do not know. There is a small switch which designates whether it recieves or sends but it did not seem to matter which position I had it in it worked. The biggest thing for me rating it so poorly is the tedious way of having to pair items each time. It was not simple. It does not remember and every time I had to put the headphones into search mode and the unit itself. But I was switching it on and off and lights blinking and not and it was just too much messing about.So, overall it transmits and recieves very well if you can get it to do so and can tolerate the messing about in order to do so. I could not.

Brilliant connectivity with my new Bluetooth headphones 🎧 specially when I'm watching tele at night without disturbing anybody 😊

Also, wie ich den kleinen( Sender-Empfänger) auspackte, war ich erst über die Größe einer Streichholzschachtel erschrocken. Aber als ich dann die Funktion testete, war ich absolut begeistert über die klaren Übertragungen .Jetzt bin ich froh über dass kleine Format, weil man das Kästchen leicht überall an den Anschlüssen unterbringen kann. Einer Kaufempfehlung steht kein Mängel im Wege. pp
