Had Vmoda--great sound but had tweeter bust on two separate pairs after a few months. Trying Sennheiser since I use them mostly for sports/workouts...they are supposed to be sweat and impact resistant. Easy to get used to varying ear bud lengths. Good sturdy jack. Quality feel and great sound, especially for the price. Good noise cancellation. Also have a pair of Shure for comparison. Have purchased a pair with microphone for my wife and her iPhone. She loves them. Sound excellent, microphone crisp and filters out ambient noise so you only hear person's voice on other end. Found them at awesome price on Overstock. No qualms there either at their service.
