Questions and Answers
How to pair it directly to bluetooth headset? I bought it to transmit audio from input AUX to my wireless headset, but I dont see a way to do that.
It is impossible to pair and connect with the Bluetooth headphones. The output can only be through a wired device. There are three usage scenarios: 1. CIS Bluetooth receiving mode: Bluetooth-enabled devices such as mobile phones and pad transmit through LE523 to a speaker or headphones with AUX. 2. RX mode, which requires two LE523 devices. One AUX connects to a TV, computer device, and the other AUX connects to a wired speaker/headphone. 3. BIS broadcasting mode: Requires two or more LE523 devices. Specific operations can be found in the manual.
If I wanted to use this as a cordless set up for a guitar/speaker, am I right in thinking I would need to buy two of these, one to transmit and one to receive?_If this is possible, what would the range be? TIA
Yes, 2 units needed (1 TX, 1 RX). Range: 100m (open area). Here's the product manual for your reference. http://myosuploads3.banggood.com/products/20250729/20250729035124LE523202504252.pdf
I paired it with both phone and PC, but in all cases it's only recognized as headphones – no sound goes through the mic. Tried all settings I could find, no luck.
Please refer to the usage method of BIS(BroadCast TX) Mode in the manual. Two LE523 devices are needed. Set the first LE523 to BIS mode for TX output, set the second LE523 to RX as the receiver, and insert the provided earphones into the OUT interface. After the connection is completed, the first LE523 can be switched to MIC in BIS mode. If there are multiple LE523s, they can be connected to multiple RX receiving devices simultaneously.
Does it work while charging?

The device is very small, regarding the Bluetooth function it works very well for receiving, however there is no way to make it work in transmission to 2 Bluetooth speakers, the manual is in English or Chinese, not easy to understand the different usage possibilities. There should be a manual for each country, that's the minimum! I contacted customer service to ask how to make the transmission work but have not received a response yet. Device ordered on July 7, received on August 1, the delivery time is very long.

It arrived relatively quickly and looks fine as well. I was able to pair it quickly with both the desktop computer and the phone. What I still haven't figured out is how to transmit the microphone sound to the phone or PC... Since that is important to me, I can only give it 3 stars. Oh, and it plays very loud effects when I use it as a monitor.
