I've been playing around with this hidden Sonos feature, and I still think it's a sleeper hit

Sonos Ace headphones.

As I've written about a few times in the last couple of months, I recently managed to upgrade my home surround sound system with a far superior Sonos setup to what I enjoyed before. Even more latterly, though, Sonos lent me a pair of the Sonos Ace headphones to see how they integrate with things, and I have to say I've been impressed.

I'd tried on the Ace a couple of times before, so I knew how outstandingly comfortable they can be to wear, but without a pair at home, I'd never been able to test their biggest USP – sound swapping.
