So I trouble myself now that I have the Sony I am for years when it comes to MP3 player with earphones and later issued with Innohrhörern habe.Erst warens several years earphones so the 15-25 Euro class in my section so 1-1 1 / hielten.Zuletzt two years I had good Innohrs the so 50-90 euros I Klasse.Nachdem with my current Bayer dynamics in terms of fit in the ear was less than satisfactory, and the sound depending on the fit in the ear fluctuated and I was constantly doing nachzurücken came I first get the idea to me "right" to buy headphones for mobile use (for the home I have for music DT-880 from Bayer dynamics and movies to Sony 700ds 9.1) This one is for mobile or eg bed or balcony use, connected to a high-quality MP3 player CowonS9. Anyway, the sound is so mobile, the absolute Oberhammer.Dabei come here usually only 192er mp3s for Einsatz.Meine favorite and most listened to musicians and bands in 320 kb / s.Mit my S9 I've the advantage of the very extensive opportunities to sound adjust by equalizer and several sound enhancement programs to the listener, the music style and personal taste. The sound with the Sony is loose 3 classes better than with any earphones or Innohr I ever hatte.Jetzt I'll my favorite groups again uncompressed new and likely machen.Das quality to the player in CD then the mobile Oberhammer be. The Sony brings super clear and clean mids and highs and very good Bass.Wobei the bass on cheap smart phones and cheap MP3 players without optimization options might be more bisl ever taste and genre too weak fail könnte.Per equalizer fat psyched and my bass enhancement program reinforced flies me the S9 away at high levels nearly the Kopp :) Cloudy, with really big headphones for home use of 3-400 or even 500 Euro class nor something goes mehr.Aber as mobile headphone with respect to the price of the MDR-1AB is just mega awesome. Absolutely crass considering how many "experts" there running around and even MP3 Player 150-200 Euro class with the accompanying usually half to full-scrap earphones then mostly 10-15 Euro class betreiben.Nach the motto "earphone is yet Earphones " Loud and Moderately sound could be a mobile headphone amplifier here at Sony not superfluous sein.Mein S9 to setting 40. 35 is already übelst laut.Und so 38 probably hear the outermost Schmerzgrenze.Werd mostly on so 32. Comfort is mega comfortable and he is very leicht.Die for so nen handset size is quite small for NEN such handset and compared to "adult" Home listeners what the mobile application to very good kommt.Nachteil is of course that he is different from earphones times just quickly stowed in his pocket lässt.An an earphone to supplement depending on the location, therefore, hardly a path leads past. Wenns but stop maximum sound on the go or while traveling, for example, should be then the Sony rult all gone. Absolute Kaufempfehlung.Ohrhörer can I stole largely in future bleiben.Endlich no back around the fortuitous in the ear more. The only drawback: MP3s poor quality or with errors afflicted or general loss of quality of MP3s from CD-quality mercilessly enttarnt.So I hear, for example, ever at high levels, while low-level segment a faint background noise that I never noticed before war.Was but is not on the handset just not silent.
