Ok so my Rockit Sounds R-50 iems have died (sound went out in right ear.) I loved them but now i need some help finding replacement iems. My budget is $30 (i am ok with spending up to $50 but only if it is really worth it.) I would like dynamic iems with a good amount and quality bass, good clarity and instrument separation. I listen to alternative, rock, hip hop, and jazz. Thank you.
