          Good for exercise

          This is great and the most of comfortable earpiece I have ever use. It’s almost like they were made for my ears. The quality of the material was just right for me, not too soft and not too hard. I really liked it. The quality was pretty decent, had a little noise cancellation too. It can’t compete with those super expensive headphones, but I think it is definitely better than others headphones within its price range.

          Kept falling out, short battery life

          The box arrived a bit crushed but inside of box was everything OK. Earphones have a good noise for that size. Was a good deal for me. I strongly recommend this product and seller to.
