In terms of audio, again it is spoiled: excellent balance of frequencies, with a well-detailed image, which is likely to appeal to the greatest number and suitable for all musical genres. Lovers of "low" will be a little disappointed, but they know to be very deep when necessary. No complaints about the media. The highs are clear without being really aggressive, so you can listen hard enough without ear fatigue.
For the material aspect, the QC25 is prettier than the QC15 it replaces, the finish looks better. It is lightweight, almost menu, but still gives the impression of strength.
