The black Shure DH 6021 are stereo on-ear headphones offering lightweight construction and enhanced speech intelligibility for use in audio tours as well as conference and translation systems. Dynamic drivers produce a maximum SPL of 86 dB and a 35 Hz to 15 kHz frequency response. Soft replaceable earpads are incorporated into the supra-aural, open-back design for comfort and user-serviceability. The adjustable headband is supported by a steel band, which provides strength while maintaining flexibility. A right-angle 3.5mm stereo mini jack terminates the durable, reinforced, single-sided cable.
