I purchased these earbuds primarily for work but once I found how nice it was not to be wired to other blue tooth devices, I was hooked. I have a Samsung Galaxy S10+ with a shockproof metal case, and was worried the mount wouldnt be big enough to hold my phone, I was very happy to be wrong! There are for sure many areas of improvement if someone cared to read our reviews. The illustration in their page on Amazon shows longer shoe strings. It would be killer on any good singers voice. Zero issues with:- bluetooth connectivity- charging, I drop the whole case on the charging pads- sound during calls, nobody knows Im using them until I askI appreciate the portability. I will probably order a different set that is built for a larger head and gift these to a smaller headed co-worker, but for now they work well Ive had them for sometime now and havent experienced any issues. The sound its impressive and the noise reduction its great. Ive been satisfied with this style for 8 years
