My criteria for selection were:
1. Very good sound
2. IPhone control (Play, Pause, Skip, Volume)
3. comfortable fit
4. Foldable for mobile use
The following models have made it to the short list and I want to compare them with each other here:
AKG 451 Mini
1. Here the AKG has been a big disappointment for me. Dull bass-driven sound without details in the music. That was already the ko (Equalizer)
2. works
3. quite well
4. The mechanics makes a very solid impression
Sennheiser PX100-II i
1. The sound is pleasantly warm with good bass, the treble are well displayed. Unfortunately, going through the slight emphasis on the bass but some details are lost. (Equalizer)
It concerns with the model to an open headphone and so penetrate outside noise quite clear when listening to music through.
2. works well, jump back to the title I have some problems
3. The ear cushions are made of foam and comfort I would describe as very high, after a few minutes I no longer noticed him.
4. The mechanics makes a thoughtful impression and he gets merged beautifully small.
Sennheiser PX200-II i
1. The sound is very natural, since nothing is sealed to what is not there, but lovers of a strong bass are probably not happy with him (Equalizer). What the detail is thrilled me the PX200 to the headphones over brings, you can hear every subtle rustling in the admission and instruments which are swallowed by other headphones he represents is. For me, the sound of the iPhone with the PX200 and the setting in the equalizer 'R & B' best since here the bass is gently raised, without losing any details or the tone is distorted. Who wants to hear very loud, will have to look for another headset, for me, the volume is more than sufficient.
2. as the PX100
3. The ear pads are made of synthetic leather and are to a certain pressure on the ear, which is slightly more than the PX100 not unpleasant, but for me. The closed construction exterior noise are well shielded, but not as complete as with ear's what I like.
4. The mechanics seem identical to the PX100. The headset makes through the foam not used a more robust impression, but is also slightly heavier than the PX100.
Conclusion:
The PX100-II is a very good headphones, with which one makes nothing wrong. Since I have a penchant for analytical listening, it is the PX200-II has become i. The only "drawback" is the headset requires good music, at dead compressed MP3 recordings he can not have a nice sound with more magic. And my train is now getting much too quickly ......
