Sony MDR XB50BS is a budget wireless in ear headphone, which sells around $50 online. It fits well and sound good particularly for heavy-bass music like electronic and Hip-hop
They are made out of plastic: flat cable, plastic housings so you feel it a little cheap.
Designed for sports, they include silicon tips and wing tips for NEVER falling out of the ear. Those tips are easily to remove and replaced
Sweat a lot. No problem. Sony claimed the IPX rating of MDR XB50BS is four. That means it can survive under normal sweat conditions.
