i would like to try to find something similar to those headphones while staying under 30$ if possible, any suggestions?

i need a budget pair of headphones or IEMs that will block a good amount of music being played in a car at volumes from 80%-100%. right now i have a pair of clip on headphones (use for work) a pair of old phillips earbuds (buds like ipod buds but actually have some decent sound) and superlux...

i received these headphones as a gift awhile ago and i like them much more than my 4$ headphones but i noticed the pleather is starting to wrinkle which ultimately leads to cracking and flaking off. i would like to get some replacements for the future but i cant seem to turn up any helpful...
