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!

No blues over this one
Very compact device that can be stuck to the back of a telly in an inconspicuous place (using velcro sticky discs, not included with the product). It has a good bluetooth connection that appears to give a strong and stable signal over the 7m distance I use it (between my living room and kitchen). On my TV both it and the bluetooth device's audio work at the same time, so you have to remember to mute the sound on the former.The device has an on/off slider switch on the side, which is small, flush & fairly stiff to operate. As other reviewers have pointed out it does not turn itself off automatically after a period of non-use, so unfortunately you have to use this switch. And remember to charge it up periodically with the attached USB to micro-USB cable.So not perfect, but considering the price I'd still recommend this product.

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.

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.

Does the job okay - could be better...
Bought this to use with my August EP650 headphones and it does the job nicely. Only gripe would be that it takes quite a while to pair up and can sometimes take 2 or 3 attempts.That said, once linked, it delivers good quality audio. So far have plugged it into the headphone jack on my PC speakers and used it with my Sony Walkman mp3 player. Range is fairly decent too - I was able to move around the house with only the odd crackle or signal drop-out.Just remembered the other niggle: battery life isn't brilliant and you'll need to recharge it after any serious use (1 hour plus), if you don't want it to suddenly die on you next time.

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

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

Waste of your money. Sound is terrible.
This is not the thing I was looking for. Bit disappointing 🥴

August MR250B Transmetteur Sans-fil Bluetooth
Ce produit est moins cher que tout les autres de ça catégorie et s'appaire parfaitement avec mon casque AUGUST EP650 et aussi avec tout les autres casques que j'ai testé dont un de marque sonixx. Pas de décalage avec la TV. S'utilise pendant la charge. Longue autonomie. Nickel...ParfaitJe l'utilise pour jouer à la playstation le soir avec le son du jeu convenable pour apprécier la partie.S'appaire à un seul matériel à la fois.Il ne reste plus qu'a créer le même produit ou l'on pourrais appairer deux casque ou deux matériel bluetooth en même temp.Bravo pour ce produit. Merci à amazone

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!
