First off, some background info:
In terms of headphones, I used whatever was the cheapest for years, until I decided that it would be worth investing in some decent headphones. My first worthwhile pair were AKG K-77's, which I still have. I like them because the EQ seems pretty flat and they respond well to EQ settings, making them versatile, but they just seem to be missing something. I still use them, but until recently, they hadn't seen much use in a while. The reason for that is that I mostly stuck to my second pair of decent headphones, which are Turtle Beach X12's that I originally bought for use with my Xbox and PC for gaming, but soon found myself using for pretty much everything.
Other than those, I have sampled many other pairs of headphones, but none of them have really wowed me.
I wouldn't consider myself a true audiophile, but I am a guitarist for the past 16 years now, so audio quality is something I appreciate and am acustomed to. I have ears trained for guitar, so I base my EQ preferences and knowledge off of that experience.
Now for the new headphones:
I'm not really looking to spend more than $100, although the pair I'm eyeballing the most are a tad over this price
I want closed, over-ear headphones. No open or on-ear, and definitely not in-ear. Preferably something that doesn't leak a lot of sound
My main listening source will be my phone, a Galaxy SIII. I don't deal in lossless files, mostly high quality .mp3's, with my bitrate limit being 192kbps, although the majority of my library is 320. I will also be using these to play guitar into for silent practicing, but that isn't that important. I might watch a movie with these on or play a game every now and then, and it's likely I use them for recording my guitar at some point. The main thing will be listening to music.
As far as music choice, I listen mostly to Metal, but I also listen to plenty of rock, punk, blues and alternative, while also listening to some classical, electronic, hip-hop, rap, and country on occasion.
I hate boomy or muddy bass, and hate muddy sounding music in general. I like a crisp sound, with plenty of articulation, clarity, and definition. I like to have plenty of bass in my music, although I don't want it to be overpowering or too prominent. I despise Beats and Skullcandy. One thing I like about my X12's is the adjustable bass boost, but I have never had it above about 40% at any point, usually keeping it around 30%. In terms of midrange, clarity is a must, and I like my lower-mids, although I enjoy the crispness that upper-mids bring to the table. Treble must not be piercing or fatiguing, but also not recessed.
So far, it seems to me that the Audio Technica ATH-M50 may be perfect for me, but I want to consider my options and get outside opinions before deciding.
I have also looked at:
Audio Technica ATH-AD700
Some of those were eliminated due to not being closed or not being over-ear, the rest just don't quite seem to measure up to the M50's in terms of reviews or hype, but I like to ask before I buy.
Sorry for the novel of information, but I try to be thorough. Thanks ahead of time for any help you can give
