1Mii ML201 Bluetooth 5.1 Receiver, Wireless Audio Adapter for Home Stereo with 3.5mm Jack Phono RCA Output, Low Latency, Bass Mode, Works with Smart Phones and Tablets, 12H Music Playtime

My 1991 Kenwood stacker hifi had been in the garage for over ten years and having set it up again I wanted to play my music from my phone through it and bought this wee gadget. Easy to set up and operate and it works really well. I'm delighted with my purchase and happy to recommend it to others.

This little device works perfectly. I can now play music from my phone through my hi fi easily. Who needs to pay a fortune for bluetooth speaker systems when I've already got a quality sound system I can use? All I needed was an inexpensive and convenient way to connect my phone and away you go! The bluetooth connection is stable and easy to connect. All in all, just what I needed.

Amazing sound quality, easy set up... Less than two minutes, no interference, amazing for the price

Great little product easy to setup good quality of sound ideal to connect smartphone or tablet to HiFi for armchair control of your streaming

This modest piece of equipment has worked well the couple of times I have used it so far. The controls are quite simple and easy to use. There doesn't seem to be any problem hooking up with the Bluetooth signal, e.g. a mobile phone can easily find it.

Meh I got it to replace another one that is quite old and starting to glitch, one of the reasons I chose this one was that people said there was no interference when it is plugged in. The old one if it was charging/pluggedin caused a background hum in the speaker. This one basically has the same problem only it’s a high pitched beeping in the background. It works (so far) and the sound quality is fine. But it is sub optimal if you can only charge when not using it

Does what it should and does it well.

This works great, am using it to pair bose speakers to my TV, works with no lag. It's also really easy to pair to device straight out of the box. Good value for the price.

It works well, taking into consideration the price. The charging indicator doesn’t indicate accurately that it is fully charged despite leaving it charged for many hours. Other than that, for most instances there is no discerning lag for me.

This tiny little device turns out to be all I needed to modernize my old stereo receiver. Now I can play all my iPhone music and apps through my stereo system and use my iPhone like a remote control to change the volume and the music source from anywhere in my house. This saved me a lot of money on a new Bluetooth receiver. I’m not sure how it compares to other similar products, but it works well for me. I do need to reconnect to it each time I use it, it doesn’t auto connect.

Exceptional sound great highs and midd. Deep bass option is brilliant too. Mine stopped working after the very first charge hence the one star review.

I connected this little puppy to a sound system that sounds great, but only has RCA inputs. It was very annoying to physically connect to the speaker every time, so this gadget was a must. Sound quality wise, you will notice some minor degradation. I tested this system by connected a Fiio E10K to the line input of the (active) speakers, and streamed a few songs ripped from TIDAL in MQA quality. I then switched to this little guy (Bluetooth streaming to the 1Mii uses SBC on Windows, apparently) and you could hear the difference, specially in high/low frequency details and some extra spatial "fuziness" to say so. That said, if you are not audiophile and just want a "that thing" to stream spotify to your grandpa speakers that sound great, this little guy will help. Oh, and usability wise, is very, veeery simple to setup.

I still have some serious hi-fi equipment that barely gets fired up these days. When it does, it usually means using a phono to 3.5mm jack to play the music from my phone. The problem is that my "mobile" phone is now immobilized on the end of a cable. With this gadget, I keep my phone with me and the music streams via Bluetooth to my 100 watt RMS speakers. It's simple and it works fine. As it contains a battery, it doesn't need to be kept plugged into a USB power supply, although I plan to do so. The instruction manual is a little flakey and makes no mention of the sound mode button. Luckily, the Amazon listing has an illustration that covers it.
