1Mii B03Pro Bluetooth Transmitter Receiver with Audiophile DAC aptX HD, Long Range Bluetooth 5.3 Audio Adapter for Home Stereo, TV, Dual-Link Support, aptX LL, Optical RCA 3.5mm Inputs/Outputs

Really easy to connect every set of headphones we’ve tried. Sound quality is really good as well. Less delay when watching movies than my old Bluetooth sender. Being picky I did have to change the delay on the TV sound slightly to get the insane spot on but still good value for money.

This device has improved my music listening by so much better, before to connect my iPhone, iPod etc I had to use a cable and the only way to use headphones was with a long extension cable. Now I connect my iPhone or iPad etc via Bluetooth which means I can easily choose my music from my arm chair, also while playing cd’s or internet radio on my HiFi system I can use my headphones connected via Bluetooth so no more long cables. The unit is so easy to use, I just connected to my HiFi and used my iPhone charger for power, it quickly found my iPad and headphones and once paired it now picks them up when powered on. It is a very stable Bluetooth connection with no issues, you cannot stream music from iPad and connect connect headphones via Bluetooth at the same time as it can only act as a receiver or transmitter but not both, this is not an issue because if I want to stream music from iPhone or iPad to Bluetooth headphones I just connect them straight to iPhone etc. This unit has given my expensive HiFi a new lease of life as I was going to purchase a new HiFi so has saved me hundreds of pounds

Has plenty of features and connections. The sound quality is good, played it out from a Cambridge Audio amp and sounded great. Bluetoothed in and also very good. Currently got it hooked into a reciever/usb player connected to wireless headphones for a desktop setup. It comes with lots of decent quality leads and connectors. Only 3 niggles, it feels a bit plasticy and lightweight, one of the antennae is a bit loose, and the lights are a bit dim so hard to see when pairing. With all the features it seems like a good deal, you get what you pay for.

Bought this to remotely monitor the sound from a mixing console without being tied down behind the mixing desk. To really appreciate the sound quality and virtually no sound delay it needs to be used together with a good quality low latency Bluetooth headset. It works with standard Bluetooth headsets as well but the sound delay is obvious when used for live music. It has a wider transmission range than a standard Bluetooth device, but not as wide as stated in the description. It is very portable and can be hidden out of site easily and comes with all the connections required to start using it straight out of the box. A number of reviews have complained about the power supply not being part of the package, but the fact that it works off a 5V USB connection, which most people have scattered all over their homes, makes that missing item irrelevant.

We use this at church, connected to the PA via the mixing desk. You can have two mobile phones connected at the same time. When one is playing the other cannot, but if you stop playing on the one phone, you can immediately play on the other. Great range, no discernable latency and no drop outs. Highly recommended for similar use.

I ordered an “ out of box” unit which arrived boxed and packaged as new saving me £30. The aim was to allow streaming to my ageing Onkyo hi-fi. Set-up was so simply using the supplied optical cable. Having a USB power cable suits my set-up perfectly. No need for charging as you get with cheaper units. The device is small and unobtrusive yet so powerful. I have not noticed any drop-outs or sound deterioration while having my iPhone on me throughout my home or garden. Sound quality is mind-blowingly good, greatly exceeding my expectations. 👏

I bought this due to its seemingly good specs regarding audio quality, and due to the claim of having a long connectivity range. audio: although it says in the manual that the (horribly plasticky) volume controls on the device have no effect when in transmitter mode, the volume controls did have an effect and added a lot of distortion to the audio. so the way to get better audio is to keep the volume control relatively low and hope for the best. - there is NOTHING audiophile about this product. connectivity: i had a lot of signal drops at a few meters distance outside in the garden. it works if i don't move much, but it isn't as good as i expected. the device feels very plasticky and flimsy, and has the overall feel of a cheap chinese product - except: it isn't cheap! I am returning mine! (I bought a Avantree Oasis Plus as a replacement, which does seem to have cleaner audio (no distortion (yet)), and has less signal dropouts outside in the garden. it also feels less flimsy - although it is also a 'cheap' chinese product that isn't cheap. but it is 20 pounds cheaper that the 1Mii right now and has an overall higher quality feel and look. it isn't great either, though, but it is the better of the two)

This was surplus to requirements, so remained unused until last week. It worked just fine the first time. It now won't go into Bluetooth Receive mode, so is useless for me. I've fiddled with it, turned it on and off, checked the manual. No dice. Too many cheap electronic devices are poor quality. If I knew it would work, I'd be happy to pay more rather than create more landfill.
