A little out of your price range, but the beyerdynamic DT 770 Pro 250-ohm reference headphones are the most comfortable and durable I have ever used. I finally had to retire my set after 16 years in the studio. Around $200 USD. I couldn't afford to replace them with the same, so I instead got a set of Sennheiser HD 280 Pro. While not as comfortable as the DT 770, they are nearly as accurate and, at 64 ohms, much more efficient (read: louder). They sell for around $100 USD. Each has 5 Hz to 25 kHz response.
