The Shure SRH840A are closed-back, over-ear professional monitoring headphones designed for critical listening, tracking, and mixing applications. An evolution of the classic SRH840 model, these headphones offer enhanced comfort and refined acoustic performance for extended studio sessions. They feature large 40 mm dynamic drivers with neodymium magnets, engineered to deliver a detailed, accurate, and balanced frequency response. The closed-back design provides significant isolation from external ambient noise, allowing the user to focus on the audio material without distractions and preventing sound leakage, which is essential for recording environments.

Comfort is a key focus of the SRH840A, featuring a newly designed, plush circumaural ear cushion with improved sealing and a self-adjusting suspension headband that distributes weight evenly. The headphones are constructed with durable materials, including a robust yet lightweight frame, and feature a detachable, coiled cable that offers extended reach and includes both a straight 3.5 mm connector and a screw-on 1/4-inch adapter for versatile connectivity with various audio interfaces, mixing consoles, and portable devices. The sonic signature is neutral and revealing, providing a faithful representation of the source material to help engineers make precise mixing decisions regarding EQ, dynamics, and effects.

The SRH840A are built as reliable workhorses for the studio, broadcasting, and content creation. Their combination of accurate sound reproduction, effective noise isolation, and all-day wearing comfort makes them a practical and professional tool for audio engineers, podcasters, musicians, and anyone who requires a trusted reference for critical audio evaluation over long periods.
