Pros: Great sound
Cons: Poor construction quality
Sound great, can't expect more from an in-ear headphone... but they're so badly constructed that mine's broke after 2 months. Cheap plastic everywhere and a connector that broke after 1 week. This headphones are a scam. Bought them to replace my old MX500 that lasted for 5 years, unfortunately Sennheiser is not what it used to be.
