    Hi there,

    I want to buy a pair of over-head headphones.

    I’m not decided between Sennheiser HD 280 Pro, Sennheiser HD 497 and Sennheiser HD 515.

    Allow me to list some specifications for these headphones:

    Sennheiser HD 280 Pro:
    Sensitivity: 113 dB
    Impedance: 64 Ohm
    Frequency Response: 8 to 25,000

    Sennheiser HD 497
    Sensitivity: 112 dB
    Impedance: 32 Ohms
    Frequency Response: 24 to 22,000

    Sennheiser HD 515
    Sensitivity: 104 dB
    Impedance: 120 ohms
    Frequency Response: 14 to 26,000

    Now, my questions:

    1) Is it a big difference between 113 dB (Sennheiser HD 280 Pro) and 104 dB (Sennheiser HD 515)? 104 dB means I lose A LOT of dynamics?

    2) Do I need a headphones amplifier for Sennheiser HD 515 (120 ohms)? That will be an inconvenience, because I want to use it with my iRiver.

    3) Is it a big difference between 24 to 22,000 Hz (Sennheiser HD 497) and 8 to 25,000 Hz (Sennheiser HD 280 Pro)? Do I lose a lot of bass? Can I hear 8-25 Hz?

    Thank you, in advance.

    Daniel

    PS Any suggestions for other headphones: Sony, Koss, Grado, etc.

    You need a headphones amplifier for Sennheiser HD 515. If you want to get something with a wide range of requency response, you may like the Audio-Technica A900 or A500. These headphones can work without headphones amp, and their sound are superb.
