Its incredible, but...
The pluses :1) The sound is really incredible, it almost sounds like a cbl hifi headset. I tested Sony, Bose, Jabra, and the io6 is much better. The sound is neutral, not too much bass (but to send if needed), midrange and highs are well defined. For classical, Jazz, Rock it's really an equal.2) The build quality is excellent, and the materials are of very good quality.3) The interface is very easy to use, the buttons are super easy to find and intuitive. Subjectively it's perfect for me. I'm a fan of physical buttons and this was perfect for me.4) The microphone works under Linux and my colleagues told me that the sound is better than with the computer's built-in microphone.The minuses:1) Impossible to connect the headset in cbl under Linux (however I can load from the computer without problems). The audio situation under Linux is not the best...2) The active noise reduction is not very good compared to Sony or Bose. On the other hand, it does not have an impact on the sound quality like on the latter. This is a bias taken by Dali I think. It's not a big problem for me, but it's important to know. 3) The hoop is too big for my head, so it's impossible to adjust the headphones correctly. After 20 minutes it hurt my ears. I have a small head for an adult, but at this price I expect better. For this reason I had to return the headphones. Without this problem I would have given 9/10 and kept the helmet.
