I have for some months been using this headset now on my iPhone 4 and I have to say that it has a really good overall package and the money is definitely worth it. The most important thing in headphones is the sound and in this discipline, the 200vi allow no notable weaknesses. The sound is understandably not be compared with much higher priced models, but for the price region definitely more than good. For other listener than me the bass could possibly be a little too pronounced, for my taste the bass intensity is but quite adequate. The build quality is impeccable, you realize that Ultimate Ears otherwise manufactures tend to higher value products. The cables are encased reasonably thick, thus preventing rather successful knotting. Even the plastic part at the point of separation of the two headphone cable is running very stable and quite large as the angled plug. The controls are located on the right headphone cable and are good to use, with complete remote control makes a very sophisticated look and definitely looks more stable than the Apple Remote. Last but not least, the headphones are perfectly manufactured per se and the earpieces in different sizes can be easily, but not too light, switch. Through the 3-pin connector, the interaction of the headset with the current iPhone without problems and facilitates its operation works tremendously. Also telephoning is possible. The earpieces included as accessories are of course very practical when it comes to his own ears, the headphones will adapt and for each should be doing something appropriate. The storage box, however, is quite a fun gimmick, but in my opinion not necessarily useful, but this is a matter of taste.
