I currently am using a set of Steelseries Siberia V2 headphones because my in ear ones suck. But I'm at around 75% on my Galaxy S3's volume at normal listening levels, and even more on the bus.
I ordered a set of ATH-M50's, but was just wondering if a Fiio E6 would make a big difference since it doesn't seem like my S3 has a lot of amp power..
Thanks, I'm still very new to the headphone world, as I'm more of a home audio guy. :D
