Dear List, As stated earlier, the audiometry headphone Sennheiser HDA 200 has been replaced by its successor HDA 300. Sennheiser will definitely not resume the production of the HDA 200 in spite of some shortcomings of the new model (esp. regarding passive attenuation). For anyone interested, Michael Hofman and colleagues from the KU Leuven have gathered and displayed technical data on attenuation and frequency response (including own measurements) in a post on their lab blog at (Thank you guys for your efforts and sharing these information with us!)
