@ayres, if you'll look back at post #506 in this thread, you can see my original comments re: poor volume level using the Haylou GT 1 plus TWS earbuds with the M2X; and then Shanling's response in post #510. I still hope to find a good pair of TWS earbuds (that I can afford) that reach proper volume levels with the M2X. I also asked for input on post #546 from anyone who might recommend a good TWS IEM for the M2X, but no response yet (except for your info on the beats). I guess there are not a lot of people in this forum that use TWS earbuds with the M2X....Maybe with a bit of luck, Shanling can do something to help us out here.
