Not that I think a replacement would have helped. Less padding around the opening and dont expect to use all the holes the laces go in because the laces are a few inches too short. The sole is cushy and is about 1/2 inch. Ive been using bluetooth over-ear headphones frequently for many years, previously primarily two pairs of Bluedio R+ Legends, which I thought were excellent, had spectacular bass (and I am a man who enjoys his deep, articulate, thorough, controlled but punctuated bass. The ear buds are differently shaped than what im used to but i think ill get used to it over time. Good:The ANC its Great,The Ambient noise making this earbud like a hearing aid. Again, compared to the 471s which dont do this at all and the plastic feels thicker and overall better made. I was worried about wireless charging since the case is fairly thick, but it works completely fine even with the case on. The Bluetooth connection is fast and the quality is strong enough. Cute but not that comfortable and definitely think they are an over priced item.
