00 Cost. For those a bit more finnicky about quality or comfort I would suggest a lesser priced, but higher quality (think DT770s) pair of stereo headphones and a standalone mic (standing or modmic). No big deal, I emailed them and they promptly shipped me a replacement pair of headphones. I sized them up a 1/2 size and they fit perfectly with socks on, but are still comfortable enough to wear without socks as they dont rub or tear my skin - which is a real problem that I have with shoes. Awesome product! The ear plug design is still phenomenal for passive noise cancellation. Charging in the supplied case was simple and automatic. The laces are no-fuss and easy to adjust. These are perfect for the pool, the beach or around the house When you have expensive shoes, its necessary to have a good place to store them.
