I have used the Etymotics ER6i most of the time and other cheaper headphones for running and general listening on the move.  For me, these headphones are BETTER and half the price of the Etymotics.  The sound quality is excellent and the sound issolation is almost dangerous it is so good.  To top it off, the curved portions of the cord fit very well over my ears and I don't have to keep pushing them in every 5 minutes to keep them in place.  I'm ordering another 2 just in case they change the model design. 

Question: How good is the phone?
Answer: For me , these headphones are BETTER
