After using the Sonos Ace headphones for about a week, I love them just as much as when I first used them.
The only downside is that the battery has to be charged more than the Seinheiser Accentum. I accepted this and it is really no big deal.
In exchange for this I get better mic/headphone active noise canceling, Dolby Atmos sound (haven’t tested yet), better build quality and better sound.
No I am not selling them. These are the best headphones I have used and it is a pleasure to be able to enjoy them. I have had them on almost all of the day and they continue to be comfortable. They are more comfortable than the Accentum in an important way. The Accentum/Bose and other ANC headphones put pressure on your inner ear when they are in use. These do not. They feel less like flying in a pressured jet, and more natural and easy. My ears rarely have to adjust using them and that is another fun experience.
I continue to grow to appreciate them. I bet you will too.
