Summary: No doubt the sound is very good. The fit could be better - am using the large buds. Not sure if I can tell the difference with the sound-insulating ones - they are less squishy so can become uncomfortable over a period. I used these earphones for 35hrs each way long-haul from UK to Brisbane. Nice, open, neutral and detailed sound - could do with more bass which is surprising considering they have a sub-woofer.
Summary: they are a bit pricey. but once you get over that initial shock the quality of the product is very good. i was original going to by Dr Beats in ear but due to bad reviews i got these bad boys instead. great iPhone control , on off, next song , start same song again , volume up and down handy clip and case included. if you have got the cash and want to treat your senses ........ you will not go far wrong with these ! recommended!
