Sorry for double reply, I did not do heavy research but just going through Amazon’s recommendations and identifying good audiophile brands, here is what I found:
I really really don’t think Apple is going to make better headphones than Sennheiser and Shure, or even Sony. I’m particularly intrigued by the Sony XM4’s battery life of 30 hours, and 10 minute charge that gets it a 5 hour charge. The worst thing about all day use of wireless headphones is that it will just die on you if you have a podcast or music on in the background all day.
