Sennheiser quality is, as usual at the rendezvous. I was amazed at the power and sound reproduction for a model so light. Used in running sessions, it is forgotten. Can be used with silicone or foam tips provided for a little more comfort. I tested it in the rain, rinsed with clean water after intensive sessions and the sound did not move. A small flat on the remote control that operates on the proprietary reader (in my case the sony walkman) but not on spotify for example.
