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.
Summary: I know my way around buying headphones. Not only are these too big for my, very normally sized, ear canals. But they are labelled (L) and (R) the wrong way around. Human ear canals point fowards and slightly downwards. This means the left and right labels are transposed on the earpieces. However, worst of all, there is ALMOST NO BASS. This leads me to suspect they might be counterfeit.
