these earphones are very hard to navigate. ie sound volume etc. the only instructions are in super small print that i struggle to read even with glasses on. The sound is only fair and a little tinny . I wasn't expecting much and was disappointed. The cost at $9 was ok but i got a better sounding set for a similar price at my local supermarket. Maybe it i can work out how to fully navigate the settings things may improve, but i want a simple plug and listen without having to fiddle about with a tiny single button
