I am looking for the best pair of closed back headphones that I can buy with a price point of $200-300. I currently own the HD 58X's -- this was a mistake, as I did not comprehend just how "open" these open-backed headphones would be, and cannot use them in the libraries or even at home due to outside noise. I am now looking to move laterally from the HD 58X's to a pair of closed-back headphones at a similar value. Initially, I looked to buy the Bose QuietComfort II's from a friend; however, after comparing these with the HD 58X's and my old ATH M50's (which I've owned for years and are my standard for headphones), I realized they were not an improvement at all and called off the deal. The highs were painful and the bass was nonexistent.
Since both the HD 58X's and Bose QC II's were failures, I am soliciting more advice and perspective from this community for my next purchase. I'm hungrier than before and willing to shell out up to $300 (I'm a student so no big bucks here). I will also get a good beginner amp for these headphones. My three primary concerns, given this price range, are 1) closed-back, 2) higher quality than the M50's, and 3) highs that aren't painful (I've noticed I am particularly sensitive to harsh highs). The ideal situation is a pair of closed-back cans that match the sound stage of the HD 58X's. Of course, the HD 58X's being so highly regarded, I know this is a feat to accomplish.
I would deeply appreciate any advice when comparing these headphones. Especially someone who can speak to the differences between the HD 58X's and the DT770's. I will continue my research to find value maximizing closed-back headphones in my price range. Until then, thanks for helping me out!
