I have found that the sound quality of this phone to be better than any other that I've owned. It's so good that I've made it my preferred media player, retiring both my Cowen and Creative. I've installed a 64 gig card and I have a bunch of headphones but for most music I find that I am really liking my new Monster Tours, for plane flights I have a pair of Pioneer active noise cancellation and for subtle tunes with high dynamic range I go to my trusty 5 year old Sennheisers. I was very surprised that the Tours have become my preferred daily use having taken over from my Klipsch S4I's. Which do you prefer and what type of music do you use them for?
