The only night I have so far, I tightened the mask too much. Was a gift for someone, but she loves them and enjoys wearing them around the house when she wants to be comfy I bought the class one hitch type so max load according tot he instructions is 300 pounds. our daughter loves them & has been practicing in them daily at home. Had 2 of these in black and they were perfect, the quality of the left and right click was perfect and crisp. The earbuds themselves are comfortable and dont fall out of my ears while walking or running. Il participe à nouveau à lidée que lindividu est construit par les circonstances, autant si ce nest plus que par sa personnalité. I purchased this because I was looking for a replacement for an old Jawbone JamBox that died. I took a before picture and will take another one after two weeks. great headphones.
