Sennheiser HD598 Measurements
- Frequency Response
- CSD Waterfall
- Harmonic Distortion
This is from old data I had sitting around. (No measurements in this heat with the noisy AC on!) It's possible that the HD598 could be using the same drivers as the HD558. The HD598 does sound a little bit better than the HD558. The marginally better enclosure could have a lot to do with it.
I like these headphones. They are a little bit more aggressive than the Sennheiser classics (HD650/HD600), but the response is still fairly even. I honestly wished the HD700 could have had the same frequency response as these cans, not that weird ass" Cyber-Grado" sound (as Mav best coined).
Compared to the Senn classics, the HD598 sounds more veiled, less controlled, more muffled, and overall lower quality. Lower fidelity so to speak, much like the SRH1440/1840, but actually not as bad. The HD598 is better than the SRH1840 in my opinion. Better more natural tonal balance, not as low-fi sounding. It also costs $450 less. The SRH1840 does have a sweeter treble quality to it though.
Hmm, I should write a quick review of the SRH1840 to further clarify my position on them.
