Can anyone comment on the sound isolation of The Composer?
I'm particularly interested in how much ambient noise gets in. There are open-back headphones that still offer relatively good isolation from the outside world. I would include the DCA Expanse in this category, which is open-back but still has some sort of shell that helps to block some of the outside sound. I'm not referring to the amount of sound that leaks out, but the amount of sound that gets in.
For context, I'm a musician and I'm used to working with closed-back headphones. I'm used to being completely immersed in the music, especially when I'm producing or mixing. When working at low volume, sometimes the slightest ambient noise can throw me off, such as the clicking of my mouse, keyboard typing, motorised mixer faders, computer fans, the hum of vintage power supplies or the mechanical action of even the most expensive keyboard. To be honest, even my own breathing can be distracting when I'm mixing.
That's why I'm always on the lookout for open-back headphones that still somehow offer at least some isolation. Amongst other HP options I've collected over the years, the DCA Stealth are my main monitoring headphones, along with studio monitors, but I'm still looking for a serious open-back option that still somhow offers at least some isolation and won't break my neck after a 10-hour session like the Audezes.
So my question is: How would you rate The Composer in terms of ambient noise?
