Sony MDR-7506 by asdfdsa
These phones are a common choice in the $100 and under price bracket, but I don't think they are the best choice. They are pretty reliable, but like most [cheap] headphones, are built kinda cheap. They don't feel very 'solid', though they'll work fine and can take fair amount of abuse and drops. One thing that really annoys me with these phones is that the muffs don't completely seal around your ear to your head, leaving the space open for sound to leak in or out. That for me is a definite reason why I prefer the Senheiser HD280 - way better isolation, and I prefer the sound, feel, and construction of them as well, overall better. Another thing I'm not such a fan of is the spiral/stretchy cord. It always needs to be stretched out, and it just adds more weight hanging off one side of the head phones when a straight cord doesn't do that. Both these and the 280's have that ''issue'', though it keeps it easy to 'roll-up' and stay neat.
The 7506's don't have a very full sound or very deep sound, but really, they are good for tracking or listening to tunes and aren't bad for the price, but like I mentioned earlier, I'd definitely get the HD280's over these everytime, as they're better for tracking, more comfortable for listening, and I think they sound better being bother wider in image and deeper in perception. The frequency response on the 7506's is 10hz to 20khz which is relatively flat, but don't rely on these for true monitoring, but you can check them for a cans reference and imaging.
The headband isn't very tight, and makes for a some-what sloppy fit, so opints off for ease of use. It comes with a 1/8 - 1/4 adapter, but the muffs don't spin or bend back or have any real features, so points off for features. Sound, eh they work but nothing great. Bang for buck, honestly I feel $100 is too much, $50-$70 is better (which is what I paid for mine new), especially when the 280's are $100. But the good thing about these is they are useful, simple, and you don't have to worry about them too much.
