I will not be buying a 3rd pair. Seem to be an identical replacement. Case was dented, presumably in shipping because they didn?t ship in a box. The price made this appealing but the charging time made it a great buy. Third test was call Quality. He uses them mostly for gaming, and music when mowing the lawn. Its really quiet as to not interrupt our Zooms & Google Hangout video conferencing. Built quality is very low, cable feels cheap, and the button literally rattles (you cant hear this travel up the cable though, so it will not impact the audio. 5 from heel to toe. They are NOT 100% cotton which was the main reason I bought these.
