Title: Near perfect
Review: The headphones are great. Lightweight and great sound. I've found that I had to -turn down- my music by about 60% because they amplified so well. From my experience with an electronic noise canceling headset (also from Sennheiser), these earbuds have passive electronic noise canceling feature. When you put them in your ear after plugging them in an audio headjack of something that is on, you'll hear some 'electronic buzzing.' If you're not used to it, it can be annoying. But once the music is on, its fine.Cons: the rubber they use for the headphones is 'clingy,' not like the normal plastics on most wiring that is generally slick. These earbuds have a sort of soft rubber which lends itself to stick to some types of clothing. Also, the wind noise the wiring causes is a pain. Running outdoors, 'fast walking' (like 3mph), or breezes will cause a whistling in the headphones. I've found that putting on a beanie (or maybe headband ear warmers) eliminates this problem
