Quick answer: the HD 600 is the more neutral, reference-style headphone; the HD 650 is warmer, with more bass weight and smoother treble. Both are excellent, both are 300-ohm open-backs that want a proper amp, and both share the same replaceable parts. Choose the HD 600 for accuracy and acoustic music, the HD 650 for a fuller, more relaxed sound.

Choose the HD 600 if…
You want a neutral reference, you listen to acoustic, classical or vocal-led music, or you use headphones to check mixes. It’s the more accurate of the two.
Choose the HD 650 if…
You want more bass weight and a smoother, more forgiving top end, especially for rock, pop and electronic music, or for long sessions. The HD 6XX, sold through Drop, is a version of the HD 650 and the usual budget route to its sound.
Amplification
Both need a dedicated amp to sound their best. A budget desktop amp is enough; see our HD 600 amp pairing guide, HD 650 amp pairing guide and Topping amp lineup.
Ownership
They share pads, cables and headband parts, so either can be maintained for years. See our HD 600/650 earpads guide.
