YMOO 2.4Ghz Wireless Audio Transmitter and Receiver for TV/PC to Speakers, Two Receivers for Two Speakers,100M Long Range Wireless HiFi Adapter with RCA/3.5mm AUX Jack, 20ms Low Latency, 48kHz/24bit

I used these to enhance the sound for a show I was involved in. The venue was a large performance hall with a stage at the front and rather inconveniently the amplifiers for the in-house system were situated at the back of the hall on an largely inaccessible balcony.We installed the sound equipment in the stage wings with 2 front facing speakers attached directly, then using these boxes we connected an output feed to the house system as well. The sound was perfect and consistent throughout the 5 hours we were 'live' and there was no noticeable lag between the direct front speakers and the bluetooth connected house system allowing the sound to fill the room nicely.Well worth the money.

This is one of the best gadgets I have bought. It takes the sound from my wall mounted TV and transmits it to my HiFi amp in a cupboard across the room. No wires between them.No lag, excellent sound quality.I tried a bluetooth device first, but it had too much lag.The YMOO is perfect and comes with a really neat set of cables and chargers too.

If you're interested in a little backstory: I wanted to send my SKY (or DVD etc) AV from upstairs to downstairs. I've tried "video senders" in the past, and they're terrible! I found an HDMI wireless extender, and also an AV-to-HDMI converter. Should all work, right! Didn't. The video was fine, but the audio was really distorted, like a warbling modulation. Rather than the hassle of discovering where the problem was, I decided to send the audio a different way, using this. And it works great! The sound quality is really good. I shall next try to embed the received audio into the received HDMI video. But if that doesn't pan out, well hey! I can plug the audio straight into my soundbar. Although there are instructions on pairing, I think this is for just in case they lose it. I just powered the two ends up and they found each other.

Just dreadful.Bought to wirelessly connect my turntable phono amp to my main amplifier.There is a clear line of sight across the living room, no more than 3m apart.The sound quality is absolutely dreadful. Unlistenable.Muffled sound. Massive hum. I tried various sources, like cd player, tuner in addition to my phono, so I know it is the teansmitter and not the source.Complete waste of money. Wish I'd sent them back.Avoid.

These work really well. Pairing & repairing always worksSound quality really good and latency so low it is almost inaudibleBut real world range is limited. At more than about 20 feet between transmitter & receiver walking between them interrupts the sound.So if you can live with the limited range - these are good.

A great bit of equipment.

Bought this to add 'rear sound' to TV using the headphone socket.Previously I had run a wire to my HiFi system at the back of the room about 25ft away, but was picking up too much hum and losing too much sound quality.With the YMOO there is no added 'noise', latency is acceptable, but I am only using the HiFi system to add some warmth and a bit of depth to the rather thin TV speaker output.Not an ideal set up, but for the money, perfectly acceptable.

I bought this to link some large speakers to a PC. The speaker Bluetooth had failed and I wasn't keen on running an enormous cable all around the room so this transmitter and receiver seemed like the best option. I have to say that so far, this has done an excellent job.All the cables needed came in the box, (which I wasn't expecting which made for a nice bonus), and setup worked first time. I'm getting no interference issues over the 6ish metres of separation, the signal noise is extremely low and it all connected up first time without hassle. Best of all is there's no sound lag either - something we've always had to endure with the old Bluetooth 4 connection.The units are USB powered, and the included power cables aren't all that long so heads up, you may need to have a USB extension cable or two on hand if you're not near a free port or power outlet.I haven't tried to use these units on anything more than an ordinary sized room where the transmitter and receiver are in sight of one another. I don't know how they'd cope pushing the signal through a wall, floor or other significant barrier. Expect that to reduce their advertised range significantly. So although I can definitely recommend this to you in a home setting, I really can't say if they'd be as effective in a larger space like a hall or a classroom.
