Skechers wide shoes are probably equivalent to 3E or 4E in some other brands. Makes my storage area look really organized. They are great, havent tried the shower, but I trust them in rain with ipx7 an they can be comfortable but also uncomfortable. I would definitely not use anything else, this was a great buyLater edit: Ive had this little brilliant case for a while now and it has taken a few falls. I?ve bought 3 other cases and none of them fit well like this one. I purchased these replacement pads for my Bose QC-15 headphones as the old pads were torn and needed to be replaced. The flap is not tight but is secure. They are about a 1/2 inch too long for my 10 1/2 feet. Since I just got them Im unsure of the battery quality or the longevity of quality of the product so I guess Ill have to check back and update. Im also using my phones EQ (since BlackPlayers EQ isnt compatible with my device) because theres a harshness on the upper-mids at about 1kHz that hurts my ears.
