The thing is that those headphones are the opposite of noise cancelling (because it is open). But that's the whole point - I want to be aware more of my surroundings than my music, especially when you're in a public space. If you care about the sound quality, I wouldn't recommend it.

For the same reason I'm generally hesitant to use a VR headset, as it almost completely blocks your senses. Total immersion is unnecessary to me.
