Negative Positive
Title: Not what I expected.
Review: This is my 3rd pair of headphones from Sennheiser. The other 2 have been perfect. The sound quality is fantastic and they have held up wonderfully. One pair is a "waterproof" running set, that I run with 4 times a week and always rinse off after I'm finished, and I haven't had a single issue with them. These on the other hand have developed static after just 5 uses. I'm so disappointed. I haven't heard a single ounce of static from my other headphones, but these have started to crackle badly if the volume is anything above the minimum. It sounds like a blown speaker. I'm worried I received a knock off brand set or something, as Sennheiser product should never act like these have.
