A ‘horizontal‘ frequency response curve on the shown frequency response plots on this website thus indicates a perceived ‘flat’ tonal signature. Here’s a look at the 400i’s pads. I’m going to just jump right into it. It is obvious the HD650 has about 2dB more (mid) bass but does not extend a … Below the distortion plot from the HD600.The 2nd harmonic distortion of the HD650 below 100Hz is considerably lower than that of the HD600, above 100Hz the HD650 shows higher distortion. The CSD showed no differences other than the small level differences. When comparing directly we can see the HD600 is the ‘brightest’ of the bunch followed by the HD650 which really only has a few dB more upper-bass/lower mids in other words ‘warmth’. The bigger the deviation the stronger the effect. V200 I love this piece of music, with its gentle violin and slow build-up. If you Google some variation on "HD650 vs HD600," you'll hear over and over that the 650 is "bassier" or "darker." Using the older pads the drivers are thus much closer to the ears which results in a slightly higher SPL below 1kHz. As can be seen the HD600 has slightly less midbass hump. Due to the impedance characteristics of the HD650 the headphone changes its sonic signature slightly when fed from either a low output R amplifier (0.1Ω) or a higher output R amplifier (120Ω). The measurements are done with the same test-voltages from a low output R amplifier and the same driver/channel. What isn’t very obvious when wearing these is the fact that the old pads compress a lot more than the newer (less compliant) ones. Below 2 pictures of both pads with 1kg weight on top of them. driver. In terms of sensitivity, HD 660S works better.

The new pad is more balanced and the ‘warmer’ signature is gone. More towards the HD580 / HD600 signature. Light aluminium drive coils ensure excellent transient response. Fortunately the HD650 responds great to a proper EQ. The HD650 has an exceptional good frequency response but is ‘tuned’ to sound speaker like and lacks bass extension and to some sounds ‘veiled’ because of this. Headphones with a good sub-bass extension have a (close to) horizontal line after the initial rise. Impedance: 300 Ω Very smooth FR with no alarming peaks or dips. ). A HD650 from 2017 (silver screen) and the fixed but ‘veiled’ HD650 (2014) below. With 10N on the entire surface of the pads the total height of the pads was only reduced from 32mm to 27mm.

Frequency response. A horizontal line shows audible neutral response in the plots on this website. They both improve strongly in balanced mode (or push-pull), probably simply because power is delivered more easily. Also distortion is quite low and it shows why it had been the top model of Sennheiser for quite some time. (Warning large file >13MB, 64 pages). The HD600 are very good headphones, but presently the same basic sound signature, but better can be had in the HD650, and the same exact sound 99.9% can be had for less money with the HD580.
