Product Description

bluetooth transmitter receiver

  • 1) Turn off the Bluetooth of all mobile phones or PCs in the house.

    2) Please ensure that the pairing distance is within 1 meter.

    3) If you still can't pair, please set both the B03+ and Bluetooth Headphones/speaker to factory default settings.

  • Restore factory default of B03+ by pressing both “v” and “ʌ” buttons for about 5 seconds until "Factory Setting" is displayed on the screen. Then it enters pairing mode and "Pairing" is displayed on the screen.

  • Please note that in order to achieve low latency, your Bluetooth headset/speaker must support aptX Low Latency. Otherwise, the receiving device may use another codec (such as SBC or aptX), resulting in an audio delay of 70-200ms.

  • 1) Volume ∧/∨ on B03+ may not work if your device does not support Audio/Video Remote Control Profile.

    2) Change the optical cable to AUX 3.5mm or RCA audio cable, the volume buttons works.

  • With many models of TVs, the built-in speakers may not work properly if you choose to use an external audio output device, this is a TV feature and its availability depends on your TV make and model.

    This Bluetooth transmitter works great. Following the directions and make sure your TV has an optical output and follow the easy to read instructions. Pairing of the Bluetooth was easy too. And now I can run two Bluetooth devices at the same time. Great for speakers.

    5.0 out of 5 stars Great when used with TV and CURRENT model Bluetooth headphones that support aptX - very low latency
    Reviewed in the United States on January 29, 2025
    Verified Purchase
    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 鶹 - 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.

    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.

    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.

    1.0 out of 5 stars I DO NOT RECCOMEND THIS PRODUCT
    Reviewed in the United States on December 19, 2025
    Verified Purchase
    I do appreciate the screen - it was useful in troubleshooting.

    The range of this unit is VERY limited - definitely not "Long Range" - I just purchased a battery powered transmitter a third it's size and half the cost and the range is twice what this unit provides.

    My transmitter is now just barely 1 year old and has developed sudden loud popping noises, and often the broadcast from the unit is garbled. The transmitter has begun to drop connectivity more often, the broadcast range has reduced even more and once dropped it is difficult to reconnect.

    HERE IS THE FINAL STRAW! The latency is just awful...and it was right out of the box. The delay is 1-2 seconds but can on some occasions stretch to 3... no kidding!

    I really expected more longevity but it's clear it's headed for the junk pile - very disappointed.
