To make it short for transfer passengers conventional earphones (especially users of the "great" iPod headphones):
Alone the transition from normal to Orhörern In-Ears move mountains.
What normal handset simply can not, bass is contrary admit shield noise and above all represent a prominent and lively sound. The EP830 are priced reasonable (not only the sound) and listen very well already in MP3 players with average sound engine (eg iPod) to. Owners of specially optimized in sound players (ZEN X-Fi, Samsung YP, Cowon) can look forward to that with their higher-value output, a significantly improved sound experience is possible.
What can be more "audiophile" hear with their listeners, classical music is & Orchestra, Electronic and, experimental music (including bass-intensive tracks, such as ATB, Tiesto), chill-out tracks, language (audio books!) And pop rock / alternative. In a completely new look seems a bit older music - much more lively, great!
Average for in-ears sound hip-hop and techno or dance (which is probably due to lack of musical depth are different by no listeners in the world), as it is in pop music. After all, even the more impulsive bass and transparency and presence of the sound remains as compared to standard Orhörern or big headphones.
Weaknesses show the EP-830 only in hard rock music, especially metal, because even at moderate listening levels stand out the ups far too strong and cruel rage for percussive and guitar sounds in the ear. Who not only listen to metal, but also "music" as speed or thrash metal, definitely should not opt for this earphone itself. This is a common problem with in-ears, and other types of headphones have this shortcoming. For harder rock music you just need other components, which then sending you not sound so great in other styles of music.
The following paragraph specifically for sound fanatics:
Compared to the EP-630 (which I had and still have) the EP830 perform better, especially in more complex music. The bass somewhat smaller, but it is clearly differentiated and sound more natural, eg bass drum beats. Centrally located, the handset behave normally optimally: Balanced at ordinary music, very present in voice playback or orchestral music, however. At normal volume sounds the treble clearer and more differentiated than in the already quite good EP-630th However, the 830 (a bit less, but still) strong problems with the heights when it comes to a) high volumes or b) the amount driven music, so for example, rock and especially metal. Even at half the volume they want in this kind of music prefer to tear out of his ears. Every beat on the snare hurts in the treble range, while the guitar rattles yet, but you can squeak it called already. Mids and bass remain up to full scale (no one holds out for the heights long) precise and unimpaired.
Technically ergonomics can not complain. Thanks to the three silicon attachments listeners fit into each ear.
The essays are easily removable and easy to clean. Insulate optimal outdoor sound, thus enabling absolute private listening. Even outsiders get with none of that, no annoying faint tinkle etc. disadvantage of shielding: Even with only one plug "on the side" in the ear fall conversations quite difficult because it makes at least as good as their service earplugs. (Advantage: sleeping aid if no such are at hand.)
The cable of the handset consists of a fairly robust material which is easy to clean and rarely "verzwurlt" even when crumpling in his jacket pocket for cables. It adheres very well in passing on many surfaces and therefore does not slide so much that jogging is useful, for example, because not all the cables from your pocket back up to your ears at every step and herfliegt. A small disadvantage arises generally at In-Ears: Touching or moving the cable can be heard very loudly in the ear.
Conclusion: A good value for money, good looks and ergonomics and a sound in the lower upper class are 90 percent of the buyers complete satisfaction, especially when they change earphones. Only metal and hard rock fans should forego possibly due to the unfavorable evolution of the heights in this field of music, if you want to apply no equalizer.
A small tip: The EP-630 from Creative only cost about half and also provide a sound image of the middle class, which is perfectly adequate for all styles of music. Audiophile sound one should not expect more of these in contrast to the EP-830, even in the approach, for most normal people but they are very well suited and much more affordable.
