wanted a spare for the ear pads for my headphones. So, I found these and was unsure if they would be the right size but theyre perfect! Im a musician so very picky when it comes to headphones. Part of the bud extends forward, and this part goes forward into your ear. Dont be fooled there is no USB dongle and these are either Bluetooth or direct connection on a PC. Arrived slightly damaged also taps looked used I tried the kuru shoes without success and also the orthofeet brand shoes and sandals with no luck, I also tried nike flyknit react which had the instep too tight and could not be adjusted and sketchers go walk which felt comfortable but these were the only ones that helped me with the pain even though the actual rubber is not that soft but what seemed to do the trick was the memory foam even though it is not that thick. Its incredibly irritating. Monumental waste of money, if you?re not careful. So i always use the boom mic.
