Its happened several times, and I eventually lost one of my medium tips (right ear). DPI changes, Back etc)This is a lot of work for something other companies do in seconds. Muito top o produto, realmente condizente com a especificação. Also has a price tag that says 22$ which is a lot less than what I paid. They were so comfy I didnt even feel the lava rocks while walking + they have enough grip to prevent slipping or falling. Just a few things you should note before purchasing- All tap functions work pretty well. I didnt even mention the cable! But for under £50. Perfect Fit absolutely love the way they feel on my feet the top of the strap underneath its very soft to the skin I was sceptical of finding any that came close in terms of fit, comfort and longevity.
