I was due to the previous reviews on the Ultimate Ears 200vi In-ear headphones with microphone gray very skeptical. I have the UE200vi and the Sennheiser MM30i ordered to choose to my previous Sennheiser CXL300II to replace (because of the lack of use and lack of micro). So both ran to the iPhone and tested alternately with different pieces of music. Tested music: pop, house music, children's music (for my daughter) and audio book. I have to say> The 200vi convinced me he has in my opinion the more balanced sound image and better, not intrusive, Bass. It fit with my audition just better in all tested tracks. The FB when 200vi is easy to operate, the Sennheiser this affects quality. The cable acts at all points Robust, which unfortunately can not say the MM30i, here's the plug rather "small" and advised the cables have different strengths. The described functions> high / low volume, pause, and rewind fold before the iPhone 3GS 100%! When much more expensive Sennheiser much accessories is also not there. When 200vi addition to those already mounted earpieces again 5 different pairs with it, also have a stable transport box. For me, the right headphone with Remote and Mic! Strong buy recommendation from me.
