Funny you say this, I've checked all of those out. Guess I went with 600 for design aswell.
These are my first "hi-fi" headphones, yes.
Would you recommend Beyer or Sennheiser?
I'll answer this with my thoughts, then duck for cover in case I start some sort of brand war. No one brand is better than the other, it all comes down to preference.
Sennheiser headphones are more "analytical", in my opinion. The sound is very clear and the tone well balanced. This lets you hear every little detail in the music
Beyerdynamics tend to be more "punchy". The highs and lows might be slightly more exaggerated. This tends to make music and gaming more fun due to strong bass and clear highs.
again, these are my thoughts. everyone hears things differently. I have owned the HD598s, DT770 pros, and HD535s.
build quality is superb on both brands. Keep in mind that the beyerdynamics go up and down in price a lot. Right now on amazon the DT770 pros (which I have) are over $200. I bough them last year for $180.
If you dont mind waiting, there is a website known as Massdrop, where people do a group order of items to get the lowest price. Headphones and other audio equipment frequently appear on here.
