I'll start out by saying I collect mid-priced headphones(between $50 - $300). It may be an odd hobby, but it gives me a certain perspective that others may not have. I'm also an engineering major, and I found the general lack of objective, in-depth headphone reviews on Amazon to be disconcerting. So, here I am, taking a shot at reviewing some of the headphones I either own or have spent a lot of time listening to. I've devised a simple six-song test and rating system, where 0 - 2 is abysmal, 2.1 - 4 is poor, 4.1 - 6 is mediocre, 6.1 - 8 is above average, and 8.1 - 10 is excellent. The songs are very diverse; I was trying to represent a wide range of genres. They are "The Chain" by Fleetwood Mac(encoded in 256 kbps Ogg Vorbis), "Every Planet We've Reached is Dead" by Gorillaz(256 kbps .ogg), "Concerto Grosso #26 in D major" by Handel(256 kbps .ogg), "I Know You Are, But What Am I?" by Mogwai(500 kbps .ogg), "Afro Blue" by Triplexity(192 kbps .ogg), and "The Patient" by Tool(500 kbps .ogg). I listened to everything on an iAudio 7 with the equalizer set to flat and all the sound effects turned off. Sound Quality(6.8/10) The Chain(6/10) - bass is nice and deep, slightly exaggerated, but still pleasant to listen to. Distortion is present, but very minimal. Mid tones and highs are somewhat underrepresented and bland, but otherwise sound decent. Instrument separation is a bit muddy. The main negative here is the sound stage, which is tiny. Every Planet(8/10) - lows and highs both sound very smooth and rich in this song. Mid tones, as before, are underrepresented and bland. Instrument separation is good, but the sound stage is very underwhelming. Concerto(6/10) - the bass in this song is deep and vibrant
