                The Superlux HD 668B and the Superlux HD 681 are both very good headphones if you like a neutral sound, but the HD 681 have a slight edge. While they both can sound quite harsh and sharp, the HD 668B also lack thump and rumble, on top of sounding a bit muddier. The HD 681 are also much more comfortable.
