I am an endurance athlete and train almost everyday. I received these earbuds as a Christmas gift a year ago and I love them. I had tried other products, in all designs and costs, that claim to stay in and resist sweat but nothing ever worked. Maybe its because I sweat more than other people or whatever, but my Yurbuds have become an important part of my training gear because they actually do what they claim to do.
I use Yurbuds mainly when doing trail runs and cycling training because I need a little inspiration when im out there. I put them in, take off, and forget about them because they never need adjusted. I recommend Yurbuds to any runners or bikers
