We have over 20 pairs of Uggs in our house between myself, my 2 teen daughters, a teen son and my husband. Im always stuck between an XS or S but I would recommend sizing up (if youre in between size) just because theyre see-through when bending over. This is always my biggest worry with headphones of any style, comfort is a necessity, they are not terrible but softer and slightly smaller pads would be nice! It was great and I ended up binge watching the entire thing in less than 24 hours! Delivery was incredibly fast. The IEM itself is a purple transparent composite material of two parts up front the nozzle and housing complete with small vent hole; while the backing is a layered alloy of silver color replete with CCA logo and the type/number of drivers. The sandal appear to have been stretched. Not sure it?s worth the money you save if you care at all about battery life. Marked it 4 stars for durability because its plastic, 2 stars for assembly because I could not stack them and 5 stars because it is simple to stack without my favorite wine in the one holder. ) to make working on the stand even better.
