2 out of 5 eggsConsidering Returning

This review is from: Sennheiser Blue CX 215 3.5mm Connector Ear-Canal Earphone (Blue)

Pros: Comes with 3 sizes of buds. Easy to replace. Good seal.

Cons: Ear-piercing highs that distorts any sound coming out of your PC/player. I've owned $10 pairs better than these.

Other Thoughts: Painful sibilance. Really brings out noise/static in recordings. Still trying to decide whether this is a defective pair or a just a poor/cheap product. My other two Sennheiser headphones sound great and do not have this problem.

Pretty disappointed overall.
