Superlux HD668B

The bigger brother of the HD681, the 668 improves the sound quality with a deeper mid-bass and sharp treble for pinpointing bullet zings. A great entry level headphone!

The HD668 makes improvements to the general design on the HD681 with deeper bass and a detachable cable (two lengths included) while still maintaining that unexpectedly wide soundstage delivered by their innovative semi-open back design. It’s like the HD681 leveled up and took a few perks.
