"They are a decent pair of headphones, but as mentioned by others, they are not the most comfortable. Not made for larger-sized heads. My mistake anyway, as I was actually shopping for 'over the ear' headphones. Oh well. They sound good with the help of the app you have to download. NOT a fan of the app. Mic for calls was sensitive and crystal clear. Worth $30 bucks."
