Massdrop again offers the AKG K181 DJ UE Reference Class Headphones for $79.99 with free shipping. That's tied with our May mention and $25 under the lowest total price we could find for a comparable pair of AKG headphones elsewhere. They feature a 3-pin coiled detachable cable, rotating earcups, mono/stereo switching, bass boost, and 5Hz to 30kHz frequency response range.
