1Mii Bluetooth 5.3 Transmitter Receiver for TV to Headphones, 3.5mm Jack Bluetooth Adapter, aptX Adaptive/Low Latency/HD Audio Adapter for Home Stereo, Airplane, Boat, Gym, Long Battery Life

I liked this product so much I have two!This device is super simple to use and I have not had any issues connecting them either as transmitters or receivers. In fact I recently used one as a transmitter on an old sound system to transmit to another attached to an old speakers system. Easy peasy!Simply holding down the number one button sets it to pairing mode and anything currently in pairing mode near it will connect. After that it connects automatically when both it and the paired device are turned on.I've not tried to use dual transmission/reception mode so can't say how that might work, but I hazard a guess most people won't be using that.I placed one in the headphone out on my old television and paired with a recent set of Sennheiser wireless headphones and can confirm there was no lag. Your experience may differ!For the most part I use the on old portable music devices so I can use wireless headphones with them and due to their compactness they add very little in the way of size and weight to what I carry.The instructions are fairly clear and there are a few other neat features in regards to selecting and showing what codec is being used through coloured lights. I would mention that I haven't noticed an auto off feature (I may be missing this) so it's best to remember to turn it off after use to avoid draining the battery.Great little device.

So far so good. Does exactly what I wanted allowing me to TX to my BT headphones from my main HiFi. I was slightly underwhelmed with audio quality at first, but once I worked out how to get it to connect using APTX-HD (the instructions are not clear - you have to press the connect button a few times after it has made a basic connection), the increase in quality was very noticeable. Not tested battery life yet, but intiial impressions are excellent. Smaller than I expected, which is a good thing!

I had a few initial problems pairing these with my SoundPeats ear buds - only one of the two buds seemed to pair at the same time. But after resetting the ear buds, pairing succeeded and the transmitter/receiver has been working fine. I have not noticed any issue with latecy despite the fact that the ear buds support only the worst of the four codecs supported by the 1Mii device.

The 1Mii Transmitter was just what I needed for a recent long haul flight, delivery was lightning coming the same day as ordering just in time for my flight the following day.Having this device meant I was able to use my noise cancelling AirPod Pros for every part of my travel, wirelessly with the device in transmit mode. That meant I was able to sit back and relax on the plane and watch the inflight films with my wireless headphones perfectly. It did sound weird at first, with audio only coming out of one side of the headphones and thought it was because I didn't have the 2 prong airplane adapter, however all it took was me double clicking the play button on the 1Mii device, to switch the audio quality as it mentions in its instruction manual, that solved the problem instantly and suddenly sounded fantastic.It also came in super handy when we found ourselves in a car that didn't have bluetooth connectivity, and just a 3.5mm AUX input, as we flipped the switch on the device from transmit (TX) to recieve (RX), allowing us to play music from our phone, to the 1Mii device and into the cars 3.5mm AUX port.It's a great little gadget to have in your arsenal when travelling and could save the day in a couple of situations I can think of. It's really lightweight and takes up almost no room in my bag sat with my chargers and the like. It's a rechargable device, I made sure it was fully charged before I left, and charged it once while away before the flight back, and I encountered no issues with the battery so it last a good while on a charge.

Paid close to 30 for an AptX enabled 5.3 transmitter according to the listing.- However I received a 5.2 Bluetooth device ML300- EarFun Air Pro 3 will not engage in AptX mode no matter what I have tried.- Annoying auto off function, there is no waking from it, you physically need to turn the little switch to "off" then back to TX or RX as needed. If you plan to hide the device behind a monitor or TV you should plan to reach for it Every Time you want to use it!- Inconsistent connectivity when pairing with a second pair of headphones. One of the pairs will lose all sound, although in theory connected, until multiple restarts of the device. Plug And Pray!- Latency! Massive detectable latency when watching movies (lip-sync on videos is horrible) or playing games (you press a game button two times before hearing the first sound from the first action).Unfit for purpise and I regret making it.

Functions ok with the tv (Sony Bravia) but absolute nightmare to pair with the 'phones. Even then, it won't stay paired. Because you're forever behind the tv fiddling with the buttons, audio lead should be longer so you can reach. Good points: usually in synch, no speech delay. Sound quality ok.

This bluetooth device is so easy to use and set up. Has a switch to choose between Tx, Rx and Off. The device is so small and compact it's great. Pairing to my headphones is so straight forward and just takes around 10 seconds. Very impressed. I use it with my TV to listen to music louder than my wife likes. It doesn't affect the operation of my Bose TV sound system, so she can select her own volume level. Also good for listening to the TV late at night while the rest of my family are sleeping. Works really well and very easy to use and charge up. Recommended.Update: Having used this for a couple of months, it works fine but I just wish the batteries lasted longer than 10 hours. My headphones last 68 hrs between charges and I'm having to charge this little unit quite often for around 2.5 hrs. Otherwise I love it.
