Brilliant little device, using it for monitoring camera audio.
Brilliant little device!! Been using the device to monitor to my camera's output with wireless earbuds. Pro's +It's tiny at just 3.5cm wide, 1.9cm Width, 5cm Length. +Super light +Has it's own battery built it (has lasted around 1:30hr and still working) +Works while being charged with 5v USB BUS power +Super easy to use!! +Sounds good with lack of delay +Distance can reach at about 10ft maybe?... but that's an estimate. Things to note -Only a transmitter, not a receiver as well. -Only connects to ONE Bluetooth headset/earbuds. -Made out of this soft rubber which is good but makes this device completely "stick resistant" so mounting it the camera via "sticky" velcro or "sticky" tape is not very reliable. +Comes with good well made cables

It works faultlessly.
Coupled via Bluetooth to low latency headphones, there is no latency. Simple to set up, this is a really nice compact transmitter, which works perfectly. I'm very impressed.

Transmitter works.
It works, but the setup is a bit confusing.

Product worked at start, manufacturer support is poor.
Good to start with but wasn't long before it started playing up and not syncing with my headphones. Worse still was the manufacturer, emailed them for help to reset, it was obvious a reset process was needed to clear the devices memory of the Bluetooth connections, but all they did was ask me question after question about the product and where i purchased it. Rather than trying to solve my problem they just gave me the runaround for a week. Then passed me to their retail arm, a support tech issue passed to retail, yeah that will work !!!!!! So I contacted Amazon with my problem, in two minutes it was solved, refund provided and returns label produced. Will never buy an August product again, but will start using Amazon more for my purchases as this is the third time I have had a need to return and item, perfect all round support and customer service.

00 inc postage as a Like New from Amazon
Well first off I managed to pick this up for £4.00 inc postage as a Like New from Amazon. I haven't decided if I want to keep it? I bought it for my music keyboard sound out into my bluetooth soundbar. So there is no working interface to set up the bluetooth. When my soundbar turns on it flashes the bluetooth light until something pairs to it. So with soundbar on & flashing blue I turned this on, pressed the only button on it for a few seconds & it started to flash, after a few seconds it connected to my soundbar. And now when both are turned off & back on it connects to the soundbar automatically. Now my problem with this is lag. pressing a key on my keyboard the sounds just fractionally lags, it's barely noticeable when playing a piece but when you just come in it can be noticed. So how this would affect something like a TV or Projector lag with lip sync very important I don't know. The device itself is tiny, haven't used it long enough to test battery life but it's only a simple USB C to plug in. I'll probably keep as I paid so little but at the price listed here now, £22.00 I think I would have returned it due to the lag.

It works - Hurrah!
I have tried a number of audio transmitters in an attempt to play, & listen to, the music on my iPods. Almost without exception they failed. They refused to pair with any of my headphones, it was so frustrating! Eventually I was lucky enough to discover this unassuming little black box. Measuring 5cm x 3cm it only has one light to let you know it is turned on. No gimmicky nonsense, no useless displays, nothing you don’t need. However, it works… it actually works. It works with all my headphones, it is simplicity itself to set up & the sound quality is really good. I love this little beauty!

THE TRANSMITTER IS GREAT VALUE FOR THE PRICE,WE;RE SURPRISED HOW CLEAR THE SOUND IS FOR WHAT WAS PAID I'D DEFINATELY RECOMMEND YOU BUY THIS IF YOU'RE LOOKING FOR A TRANSMITTER.YOU WON''T BE DISAPPOINTED.# AND YOU'LL GET EVERYTHING A MORE EXPENSIVE TRANSMITTER GIVES FOR A REALLY GOOD PRICE. RECOMMENDED SELLER FOR HIS HELP AND REALLY FAST DELIVERY

Great little device
After buying the August EP650 I seen that they sold bluetooth receivers. I use it to connect my headphones to my TV at night so I don't wake the family. There's no lag in the sound the quality is great and pairing is straightforward. The receiver is rechargeable by and lasts quite long.

calidad/precio aceptable
Cumple su función correctamente ,la batería dura mínimo seis horas y carga en dos. yo lo utilizo para oir la radio del movil junto con los auriculares augusto ep605 y perfecto buen sonido sin cortes. Cuando tiene baja la batería se corta el enlace pero con uso normal perfecto.mas de 15m de alcance. para mi buena relación calidad precio. Con tv hay un poco de retraso pero aceptable(muy poco,te acostumbras) aunque no le doy ese uso.

great transmitter, powerful!
August MR250 Bluetooth Wireless Transmitter - Audio Sender for TV to Bluetooth Headphone - Stream Music from 3.5mm Audio Out to Bluetooth Headphones, Speakers and Receivers - Compatible with August EP650/EP640/EP636 (Black) This is an incredible transmitter! just placed it in the middle or in the center of the studio and everywhere I went in a 30 M area it delivered an incredible sound to my August EP650 without interruption.This transmitter worked with other bluetooth appliances as well, found some time to pinpoint the code but worked very well! This is a steal at this price! can't wait to try it with the August speakers that I already ordered! Thank you August! great stuff!
