Jbl headphones are the best headphones I have ever used. Its very comfortable and its bass sound is awesome.I have a jbl synchros S300i headphone. Its an awesome headphone.It has plastic circular ear cups that straddle the line between on-ear and over-ear by using soft padded cushions to isolate your canals, held together with a padded steel headband that can be adjustable per side. I loved it because of the product quality and its bass sound which gives great feel to the music. I suggest it to everyone.
