Comparing some Headsets

I was looking for a good and affordable headsets for to-be-mine Sandisk Sansa e280 (darn, 2 more days have to wait till it is delivered) MP3 player (will put a review on it later).

Upon searching on google, I landed on a site http://www.headphone.com that compares the 'really' technical comparisons (not just a sounds-like-a-geek-but-a-stupid reviews). The web gives a frequency response graphs, harmonic distortion graphs, isolation and impendances for the tested headsets (unfortunately, they did not test on Bose headsets).

Here I try to compare between Sennheiser's PX100, Sony CD3000, Apple's Ipod earbuds and KOSS KSC55:

Frequency Response

Harmonic Distortion Products



So How to pickup the best headset? The rules of thumb are:
  1. Pick the headset with the flattest and widest frequency response
  2. With the lowest and flatest spikes in harmonic distortions
  3. Isolation; This is a measure of a headphone’s ability to isolate the listener from outside noise. The deepest notch for the noise frequency usually good ones.
