Sennheiser offers pretty good comfort and a sound signature most people will enjoy. I had been a fan for the last 4 years but I wanted to try something different. Bought and returned the K240 Studio, great sound (for the money) but they lack a lot of bass extension to me. Today I got Philips X2HRs, first impressions are very positive. To me, the HD 600 line has a very unique midrange and soft treble. Everything else isn't that great compared to the competition IMO in the same price ratio. I get your frustration but most people first hifi headphones are usually Sennys.
