I have pretty big ears and this is the first time Ive ever had my ears totally encapsulated by headphones. The end product was truly wonderful. Anyhow, lets get started. Boots can easily fall out as there’s not enough room to hold them. After using this with a smartphone, I found out that the instability problems (stereo sync, choppy sound) is not because of the earbuds, but because of my laptop. My toes touched the end but werent crammed or anything. Minus the increased price due to shortages (thanks Valve) this wasn’t a horrible purchase. The sound quality and battery life are exactly what I was looking for. Im not much for reading instructions so likely I could have just read to take them off. I will have them sewn back up but will never buy anything from the company who sells them.
