We don’t recommend buying these if you want a dedicated pair of headphones for working out. For most other listening scenarios, though, they’re an excellent option. If you can get past the weird controls and aren’t making a habit of singing out loud in the rain while you listen, the Sony WIC300s are an affordable option.
the unassuming Sony WI-C300 delivers an impressive listening experience rife with detail. The build quality is lightweight but strong, and the battery life is on par with headphones that cost three times as much.

Unfortunately, they have a weak build quality that doesn't feel as durable as some of the other in-ears in their price range. They also have a slightly bulky module on their cable which may be bothersome for certain listeners.
