The use of low-impedance headphones with portable MP3 players can damage your bass!


Below a list of frequency response curves showing the synergy between the iPod and different headphones, extrapolated from the 20 ohms response (measured by the German hi-fi magazine «stereoplay»).

Sony MDR-F1 (12 ohms)
20 Hz -17 dB ... 30 Hz -11 dB ... 40 Hz -8 dB ... 70 Hz -5 dB ... 100 Hz -3.5 dB

Reference curve (20 ohms)
20 Hz -10.5 dB ... 30 Hz -7 dB ... 40 Hz -5 dB ... 70 Hz -2.5 dB ... 100 Hz -1.5 dB

Etymotic ER-4P (27 ohms)
20 Hz -8.5 dB ... 30 Hz -6 dB ... 40 Hz -4 dB ... 70 Hz -2 dB ... 100 Hz -1 dB

Grado SR 60 (32 ohms)
20 Hz -7 dB ... 30 Hz -4.5 dB ... 40 Hz -3 dB ... 70 Hz -1.3 dB ... 100 Hz -0.7 dB

Koss Portapro (60 ohms)
20 Hz -3 dB ... 30 Hz -1.5 dB ... 40 Hz -1 dB ... 70 Hz -0.3 dB ... 100 Hz -0.1 dB

Sennheiser HD 590 (120 ohms)
20 Hz -1 dB ... 30 Hz -0.5 dB ... 40 Hz -0.3 dB ... 70 Hz -0.05 dB ... 100 Hz -0.0 dB

The old wheel with the moving part had a good ball-bearing and used infrared light gate to track movement. It seems to be tons more reliable and have much more endurance than the new "solid-state" wheel.

I just got a pair of Beyer 250-80 to go with my "ancient" 5gig iPod. To my slightly aged ears, it sounds wonderful and has just the right amount of isolation so I'm not totally cut off from the outside world. Extremely comfortable, too. The next step is to start advertising my Ety 4p, which also sounds wonderful but never felt as comfortable to me.

By that time they will hopefully be cheap enough that you won't have to sell off your MD equipment. Either that or you could sell your equipment off and get a 30gb or 40gb iPod.... the key word here is *hopefully*.
