You don?t have to carve holes in the top. I dont need to dress up obviously, but I like to wear a nice pair of athletic pants and shirt but dont see a need to wear shoes in my house. After I tore the cord of my favorite AKG in-ears twice, I needed something more appropriate. They slip up and down when Im walking tho and end up hurting between my toes cause they curl up to keep them on. No problem with them rubbing against my shin or being too tight. Great sound quality and very comfy to wear. Great Sandal, light weight and comfortable. To add insult to injury, AKG designed the ear cups differently between k371 and the k371bt. Thank you for a great product. The sun did set these babies on fire but they aren?t going to blind anyone.
