I thought the clip would keep them in my ears but they don't so I was constantly fussing with them. So they hindered me trying to work which defeats the purpose. I used them with a stretch head/hair band but I had to stay perfectly still so no go. For the 2 minutes I sat and listened, the sound was great. Also, I'm so used to Walmart's generous 3 month return policy that I didn't notice, this "proseller" decided to limit returns to 1 month so I'm stuck with these $20 gizmos I can't use. Lesson Learned! Check out the seller affiliates carefully.
