I have had no experience with the Sennheiser EH 150 Headphones, but I
have been using now for many years with great enjoinment the Sennheiser
SD 590.  Sennheiser offers what they call High End Headphones - open,
light weight dynamic headphones and the model SD 595 supercedes the SD
590.  More expensive models are the HD 600 Avantgarde and the audiophile
HD 650.  The audiophile HD 650 is supposed to be the top model of the
High End Headphones.  All the mentioned headphones, are, of course, of
the wired type.
