Even through wake, wind and boats passing, it holds the position and doesnt drift. Used by a team of marine observers at a small course powerboat race. miracoil 3 Also, Amazon didnt let me post a review which said the same thing (without any violation of posting guidelines, I might add), so this is my second review. Its very good for transportation but when product is removed from packing, it makes a huge mess. miracoil 3 I returned these without putting them on. miracoil 3 Sound leakage is almost zero. These are my go-to shoes when my feet ache from working out or hiking. Only "con" when you reach max volume the music pauses for like 2-3 seconds, meanwhile the speakers will play a tune, to let you know max volume. miracoil 3 The headphones sound good, have decent noise cancellation and are mostly comfortable to wear for a few hours a day. I didnt use often but they lasted about 1 1/2 years but I had to charge every time I used them and often it gave me the "low battery" message right away.
