Summary: These are amazing headphones for any basshead who desires a nice clean sound. Though the balance is a little bit wonky, the clarity is all registers is amazing. The sound isolation is decent. I use these in school hallways and can't hear anything or anyone if the volume is at 50%. The bass is super powerful but to the point that it makes the mids and treble pale.
Excerpt: I bought these based my previous (good) experiences with Sennheiser products. These earbuds are probably my favorite based on sound quality. I consider myself a semi-audiophile and these are amazing for the price. Also, the mic clarity is very good for phone calls, Skype, etc. The leatherette bag they come with is very nice, too. I would buy these for anyone.
Pros: Comfortable, Easy To Use, Great Sound Quality, Quality Microphone
Excerpt: The sound quality on these are pretty good. I primarily use them for talking on the phone and haven't really used them for listening to music, but they've been working well for talking on the phone. They are also very lightweight and comfortable and do not fall out of my ear. I wouldn't say they're "flimsy" construction, but I've seen more expensive headsets with more solid construction.
