To be honest, it exceeded my expectations, as I thought it would be low quality for the price (it is not, it is great quality). One time is clear and smells like tea tree, then it?s cloudy and smelly minty, now it?s hardly any smell. It says dry clean recommended, but I washed it alone on gentle cycle and then air dried it and it did just fine - The light weight makes it feel less-than-sturdy, Especially on carpet. As a result, you might not hear an enemy behind you or subtle tones in a variety music/sounds. Ok for the $$. I love my navy blue flip flops or sandals from Havaianas for those hot summer days. Im thinking its number 2 as the piece that goes into the ear is quite thick and made of very hard plastic which seems to cause me pain after a while of listening unlike my other pair which I can literally wear 24/7. The padding is decent but nothing that even slightly resembles memory foam and it will wear down soon. I generally walk along paths and maybe if I?d known how quick the sole would wear I?d have saved these for more grassy/ woodland walks.
