About the Diana MR
The Diana MR is an open-back, over-ear planar-magnetic headphone with 63 mm drivers. Its 30-ohm impedance and 93 dB/mW sensitivity are intended to make it usable with portable sources as well as desktop headphone amplifiers. The design includes an aircraft-grade aluminum frame, a suspended headband strap, pillow-top ear pads, and a 1.5 m JPS Labs cable with a selectable connector termination. This is the Diana MR model, not the later Diana MRx.
