Summary: These are bazaar. I have an older set of Sennheiser buds with the loop that wraps around the back of the neck which have excellent sound, so I was looking forward to a lighter, even better performing earbud set. These were terrible. the design for fitting in the ear is bazaar, and totally ineffective. They fell out of my ears easier than stock ipod buds without the little add-on loops. With the add-on loops the stay loosely in the ear.
Pros: Able to return them easily through the excellent service at Crutchfield. Makes every other earbud in existence seem good.
