Wishing for a high quality music environment, I did some research into audiophile headphones. I learned that there does not exist a “best” pair of headphones. Rather, there are various headphones which are great for their reproduction of various parts of the audio spectrum. For example, the ones that I bought, the Sennheiser HD 598s are known to be good (considering their price) for listening to the higher side of the spectrum; i.e., vocals and other high frequency sounds. I must say that I love my Sennheiser HD 598s. Sennheiser produces a couple of other highly rated headphones, including the HD 650 and HD 800. Here are some other headphones which have good reviews: Beyerdynamic DT 770, AKG K702, Grado SR60, Grado RS1, and the ATH M50. Also, to get the best sound out of the headphones, one should buy an amplifier.
