For the classic, brighter, and more analytical sound, the early, non-serial numbered (or low serial number) Beyerdynamic T1 Generation 1 is widely considered the best version, favored for its technical precision, 600-ohm impedance, and superior treble detail. These are considered to have a more neutral signature compared to the warmer, more bass-heavy 2nd Gen. These happen to be in exceptional original condition, having been used in limited studio applications. Please note that these are 600-ohm headphones, and as such, benefit most from a powerful amplifier. Comes with original box, cable, and 3.5mm adapter.
