Review: Works GREAT - I got tired of buying Bluetooth headphones for tvs that were flimsy and didn’t even have noise cancelling features. Bought this Bluetooth transmitter and was able to use by own active noise cancelling headphones and I couldn’t be happier. The instructions aren’t the best, but I figured it out and paired the headphones on the first try. And now they pair automatically every time and I love it. Range is about 50 feet, through walls and floors.
Review: Great when used with TV and CURRENT model Bluetooth headphones that support aptX - very low latency - I use my 1Mii B03+ in Transmit mode, and am very happy that with it and aptX compliant low latency Bluetooth headphones it has very low lag that is great when watching films, concerts, dance, sports, and other performances! I bought it because my TV's built in Bluetooth 5.0 had horrible lag where you would see a baseball hit the bat and fly across the field and THEN a second later hear the crack of the bat. The TV's Bluetooth latency was so bad that watching action movies or sports or dance performance or even conversations was very frustrating. The 1Mii B03+ WHEN USED WITH BLUETOOTH HEADPHONES THAT SUPPORT aptX low latency solved the latency problems. This 1Mii B03+ WHEN USED WITH BLUETOOTH 5.3 or BLUETOOTH 5.4 headphones that support aptX low latency avoids the delay between what is seen on the TV screen and what is heard through the headphones! PLEASE NOTE that the only headphones where I got very low latency were those with aptX support! I've tried several Bluetooth headphones and some "Bluetooth Speakers" and for best results you need to make sure that you aren't matching connecting older Bluetooth 5.0 and even some Bluetooth 5.1 or 5.2 headphones or surround back speakers as you can get what sound like echos. If you want to use it with your TV it has Digital Optical as well as 3.5mm analog stereo inputs and I've used it with both inputs without any difficulty. The unit has a long range, which in my experience is both good and bad. The Good part of long range - It has excellent coverage in a 1,100 apartment with a strong signal everywhere in the apartment. The Bad part of long range - A couple of neighbors complained that when I turned it on their Bluetooth devices dropped their connection. I thought that was strange, so I tried duplicating their experience with three different Bluetooth devices and found the same thing happening with my other devices. My solution was to change the orientation of the antennas so that both antennas are horizontal, with the left antenna pointed to the left, and the right antenna pointed to the right. This apparently decreases the received power and lowers the range enough that while I can still have complete coverage in my apartment, my neighbors no longer have their Bluetooth connections drop when I turn on the transmitter. If you are in a single family home, you shouldn't run into this issue. In addition, I purchased a special power strip from desertcart - ECG-7MVR Energy Saving Surge Protector with Autoswitching Technology, 7 Outlet - and I plug the TV into its "Control" outlet and the 1Mii B03+ into a "Switched" outlet, and then I adjust the sensitivity of the "Control" outlet so that when the TV is turned on the power to the "Switched" outlets is turned on, and when the TV is turned off, the power to the "Switched" outlets is turned off. That way, the 1Mii B03+ is only powered on when my TV is turned on. Overall I'm very happy with the 1Mii B03+ and am thrilled to have almost zero lag between what is seen on the TV screen and what is heard through my aptX compliant Bluetooth headphones.

### ⭐⭐⭐⭐ Solid sound and signal
*by A***R on May 1, 2025*

Works well, setup was simple, and it sounds great. I am using for transmit currently to add Bluetooth to a 2011 Panasonic TV in a guest bedroom that only has an optical digital audio output, and it is pretty seamless. Has connected to multiple BT earbuds, and headphones without issues and reconnects promptly.
