I do not necessarily compare with other KH of Sennheiser, AKG or Grado because I can not make a direct comparison with the same music this Earphones. Nevertheless, as much in advance: it sounds about as good as a Grado RS 2 and better for me like a Sennheiser HD 700th Instead, I see him with my speakers Neat Elite SX of which I am really convinced one hundred percent. The LS will be powered by a Naim SuperUniti tonally fits perfectly with the Neat. In "Sunrise" by Norah Jones (ribbed CD) the LS still have ahead, the recording sounds very audiophile and detailed. Jazz is the great strength of the Neat. Nevertheless, the Philips sounds very neat, but it lacks the last 3% here to unlock. This is evident, however, only in direct comparison. When Joe Cocker- "Talking Back to the Night" (an old recording), it is similar. When headphones you realize rather, that it is only a mediocre good reception. Tok Tok Tok - "Walk on the Wild Side": Again, the Neat have the edge. Santana: "Samba Pa Ti" and "Black Majic Woman": here you can hear the KH. some noise (a very old recording), so these sound recordings on the LS. pleasant. In Westbam "terminator" the tide turns: the KH sound a little better and abysmally with electronic music. In "Pulvertum" by Niels van Gogh the Philips sound simply sensational, with Ginuwine "Pony" is similar. Music with lots of bass share sound just perfect on the Philips. When Adele "I''ll be waiting" the KH liked better because the stage was wide, similar to the Blu ray of Adele I Own ebenfals. Then I still made some comparisons with Hig Res Images (24 bits 88- 192 kHz). Overall, one can say that sound better from the trend ago audiophile recordings on the LS. But given the very reasonable price of Philips (about 190 to 250 euros) the performance is simply sensational. The impedance is good-natured, as being in harmony with both my Dac as well with my iPod. You can stop the headset for hours without tiring. And most importantly, he fits right away without anything having to adjust. My son (3.5 years) it fits well right away. The cable as the rest of KH. are processed very neat and in the case of a cable break can replace the cable easily. Therefore: full marks, buy!
