I dunno, I've always been a bit sceptical of those things. For me at least, I do want to hear a bit of peripheral sounds, but I also don't want something that sits around my neck either. Wireless buds are great because they don't get caught on anything, and I can sleep with them, and they're more portable. The problem with any rubbery tipped earbuds for me is they block out so much noise I don't get any sense of the street, or any bus/tube announcements, and I can hear myself breathing, swallowing, and all those other internal noises which I don't want to listen to. They're entirely counterproductive. Personal preference obvs.
