The Shure SRH1840 is a pair of headphones that sport matched 40mm drivers. These neodymium magnets provide a frequency response of 10 Hz to 30 kHz, doing so in a balanced, clear, and articulate manner, with accurate bass and smooth, extended highs. The steel driver frames sport vented center pole pieces to eliminate internal resonance, ensuring a consistent performance at all volume levels. The open-back earcup design promotes proper airflow, which results in natural audio with a wide stereo image and a greater sense of depth than many closed-back designs.
The headphones have a lightweight and durable frame that utilizes an aircraft-grade aluminum alloy yoke and stainless-steel grilles. Lightweight at 0.6 lb, the SRH1840's headband is fully adjustable to provide a snug and secure fit.
