Request them to replace with good quality as it got 30days warranty So happy the Size Large fit. 7 year old girl already wasted this pair of poorly shoes made even if looked good. Thats a great price when you only have to buy one pair a year because they hold up so well. Many ear canal wireless IEMs or neck-resting wireless sets have issues with dropping the signal when the phone is in your pocket or your bag. I’ll install the remaining in my shed for more standard use. I used a mixture of youtube reviews, customer reviews here and my own brand experience and audio knowledge. I loved them but only after about a week the backs of the shoe bottoms already have started too come off 😑 It gets very loud for the size and the mids and highs are very crisp. But had to return them for one size smaller, my original size, because the reviews recommending to order a size larger than normal are definitely no longer the fact.
