These wireless earbuds are the best-sounding ones I've ever used, solving most of the issues I had with my MTW1. The sound quality far surpasses that of my wife's top competitor earbuds. However, after slightly more than a year of use, the right earbud stopped working. Despite trying all troubleshooting methods found online, none were successful. Now, even after charging, the left earbud doesn't light up or function either, and I can't connect them since the touch controls on one side aren't responsive. It's truly disappointing to have such a sad experience with a product that offered excellent sound quality.
