These were a Christmas gift for my wife, who has eczema. She had a generic set of bone conductor headphones for a Disney trip two years ago, which she loved, but eventually gave out. We knew Shokz were the best in this line of headphones, and have been EXTREMELY pleased with the easy of use, the comfort (especially since they don't impact her eczema like other earbuds/headphones do), and the sound clarity.
I absolutely love my open runs! I work at an elevator and I no longer have to worry about my ear buds falling into a pit. I actually can hear the other person when I have a call.
