I am looking to buy some headphones for my ipod after experiencing the discomfort of earbuds. I therefore need low impedance (less than 40 ohms)(I don't want to carry around an amp), but also would like to retain great sound quality for the price of around $100 (Great quality meaning for me, clear lows through highs, good punch and low distortion). I have been doing research across many different brands and styles and have been lead to an on ear style and four specific products, One I know has not been released, but I would like opinions on it anyways if you have researched it:
