1Mii ML301 Airplane Bluetooth 5.3 Transmitter Receiver,Dual Link Wireless 3.5mm AUX Bluetooth Adapter with aptX Adaptive/Low Latency,HD Audio Transmitter for TV, Stereo,Headphones,Travel, Boat, Gym

Used very successfully with a TV with no Bluetooth. A little out of synch, at times with people speaking but not a problem. Signal received in a room , two rooms away. Charge time good as is the battery life.

Easy to use - I just plugged it into my stereo's audio jack, pressed the pairing button and it paired with my earphones immediately. Now that it's paired, it remembers even when I've used the earphones with other devices. The signal is strong - I can comfortably listen upstairs to music being played on my stereo downstairs. The only slight downside is that it doesn't routinely show the charge level. However, the charge lasts a long time.

Great gadget that allows us to listen to both TV and audio, at volume, without disturbing the neighbours in our multi occupancy building

I was worried about latency since my Sony buds are only SBC and don't have the latest aptx codecs. However testing on large Sony TV and smaller 12in monitors close up the lip sync is not bad. There may be a delay but it is so small as to be unnoticeable, very marginal, and you soon forget to actually look for it and just watch the program. So any aptx devices must be better. Pairing was no problem, all my phones and eg Audioengine speakers and mini bluetooth speakers all paired immediately and without problems. Tried receiving with non bluetooth powered speakers, all fine, very reasonable quality, no noticeable hiss or distortion. For performance at this price I think this is a steal.

I brought this as a back up for an aux line into vans radio system. Van Bluetooth wouldn't work. Easy to pair with phone, good sound. It cheap and it works, no idea of battery life, still going after 5 hours

Device connects to various Bluetooth speakers and the 5 or 6 Alexa units i have around the house but that's all, it connects then does not stream music. So am returning the unit.

Great no time no time lag,works with my tv

My need was to be able to send output from my hi-fi (CD and vinyl) located in the dining room, to a pair of Bluetooth equipped bookshelf speakers in the sitting room. This device solves the problem well. You need to charge it regularly, of course, but otherwise it’s a good and fine product. One issue that new users might need to be aware of: make sure you take this device (unplugged) close to the target for pairing (inches, not feet away) then, once paired, retreat to the source (mine is more than 18 feet away), and connect it via the headphone socket, as illustrated in the photo.

Excelente calidad, cumple con lo ofertado. Muy práctico, tamaño ideal Gran opción para conectar 2 aparatos para escuchar audio mediante bluetooth al mismo tiempo, si tu dispositivo no tiene esa opción. Estoy muy feliz con la compra

It's really mini. Smaller than what I expected. I like the size. At first I couldn't figure out how to pair with my headphones - but I just had to put my headphones in "pairing mode" which for sony wh-1000xm3 is by holding the power button for a few second. After that I was disappointed to find out how low the level of sound is - but it turned out I had to increase the volume from the headphones itself - the sony wh-1000xm3 have touch controls, and now they sound great. I'm tempted to leave one star review, so if you're like me and read only the negative reviews you would see this comment and know that "there is a way". I saw other buyers complaining that it worked only for short period and then it broke - I guess I'll have to test that. Overall I was looking for something small, simple and not very noticeable, that can fit in my headphones case, and I believe I found it. Jan2026 - update Just completed a 24+ journey from the States to Europe and the transmitter worked great . Battery held for over 13hrs flights. Didn't notice any delay in the sound. Admittedly didn't pay attention on the quality of the sound, as I don't expect Hi-fi sound in the plane, but I don't have any complains. My headphones connected immediately, without a problem. At first I panicked, as I couldn't hear anything, but I quickly realised I have to increase the volume from the headphones themselves. For my wh-1000xm3 - the right side of the headphones is touch sensitive and you can increase the volume from there. I aimed for about 50% volume from the headphones and then about 50% from the in-flight media itself.

una autentica maravilla conectar cualquier casco de cable vía bluetooth. Como pega, cuando hay un pequeño sss cuando se conecta o desconecta y no suena nada. Pero desaparece en cuanto empieza a sonar o se va. como mejora: que añadieran el micro y también valiera para llamadas. pero por el precio es sensacional y ojo, en emision también es otra maravilla, puedes ponerte cascos inhalambricos en un piano y no se aprecia retraso (un poco si eres quisquilloso, sí)

Permet d’éviter les fils, connection facile, efficace

I used this the replace a Bluetooth to FM transmitter in my car and the sound quality difference is astounding. My phone stays connected to this adapter even when I’m not inside the car, and even if I forget to turn it off, it turns right back on as soon as I get in the car, don’t have to wait for it to charge or nothing. Only complaint I have is that the charging cord could have been longer, but it’s not the end of the world.
