NO SMOOTHING is applied to the shown plots. Most measurement sites have some smoothing applied which ‘irons flat’ sharp peaks and ‘wiggles’. I do not use smoothing because some info about sound quality is lost when plots are smoothed.

Aside from a small correction of the microphone itself also some correction in the lowest frequencies is applied to the plots to compensate for the perceived loss of bass when using headphones. This is described HERE in more detail.
A ‘horizontal‘ frequency response curve on the shown frequency response plots on this website thus indicates a perceived ‘flat’ tonal signature.

ALL measurements are made with a good SEAL on a flatbed measurement rig.
The
shape of your head, bone structure, pad size, pad ‘softness,  (compliance), hair or no hair and or wearing glasses may (drastically) change the frequency response of some headphones, so… your personal experience may differ substantially from these plots.

I found this in a junk box and thought I’d measure it.
It is a cheap (€ 15.- to €20.-) but comfortable on-ear headphone with little clamping force and ‘decent’ isolation.
It is not even remotely close to ‘Hi-Fi’ and music sounds ’empty’ but can be used to listen to speech pretty well.
Great for listening to radio programs (that doesn’t have music in it), TV programs (but the wire is too short) or language courses etc.The dual entry cables come out of the hinges and can rotate 180 degrees. The cable run nicely in front of you. Left, Right

No sub-bass but lows are still ‘decent’, no highs extension but there is still energy up to 10kHz and isn’t bright.
