I have to jog or run on the treadmill at the gym bought this neckband headphones from Sennheiser. I had previously tried several in-ear headphones that are but slipped during jogging again and again from the ear. With this product, I am very pleased, however. The neckband fits comfortably over the ear and does not interfere in the neck. However, the headphones insulate very poor, so that the adjoining persons can listen to the music / need. Therefore, only four out of five stars. Otherwise strong buy recommendation!
