I already have the QC15 is already an excellent product.
I tested the QC25 is an upgraded version in every way.
I also tested the QC20 headphones and I was amazed by the noise reduction QC25 and QC15 in UPPER helmet.
Incoryable!
I will not make long comments.
For résumr: noise reduction is significantly better than the QC25 and you can continue to listen to music even if the battery powering the system is empty.
Noise reduction is EXTRAORDINARY. A problem with the neighbors? Work at home? A storm makes noise outside? This is the 14th of July? ... More needs to invest huge sums in soundproofing your home and another double glazing. 299 euros will be enough to satisfy you!
More than just a headset: THERAPY!
By cons it is not free from defects.
The wire is annoying compared to headphones or you can remove the wire and have the helmet on the head (provided you do not want to listen to music).
The small box containing the battery and controls weigh on the wire and thus on the headphones making it necessary to put it in a pocket to support it. The headset even keeps an advantage.
By cons I repeat because it is a recurring question that I've never really found an answer on the net: yes reduction exceeds the QC 25 headphones!
