Sennheiser HD-26 PRO Core Technologies and Features

ActiveGard™ Hearing Protection Technology: Built-in three-stage adjustable volume limiter, which limits the maximum sound pressure level to 105 dB, effectively preventing sudden audio peaks from causing permanent hearing damage and ensuring the occupational safety of professionals.
Broadcast-Grade Sound Quality and High Isolation: The closed-back, on-ear design provides excellent passive noise reduction, accurately reproducing audio details from 20 Hz to 18 kHz even in noisy broadcast vans or outdoor environments.
Lightweight and Comfortable Design: The headphone body weighs only 180 grams, combined with soft, replaceable ear pads and a split headband design, effectively distributing pressure on the head to ensure comfort during long periods of wear.
Professional Durability and Convenience: Equipped with a detachable, structure-borne noise-resistant 1.5-meter cable, effectively reducing noise caused by cable friction. The earcups can swivel for single-ear monitoring, meeting the needs of DJs and live engineers.
High Sound Pressure Level (SPL) Capability: With ActiveGard™ turned off, the maximum SPL can reach an astonishing 128 dB, capable of handling critical detail monitoring needs in extremely noisy environments.

ActiveGard™ Hearing Protection System Explained

Utilizes Sennheiser's patented sound compression circuit to process excessively strong audio signals in real-time, removing peak energy without introducing distortion.
Offers a three-stage attenuation setting, allowing users to flexibly adjust the protection level based on environmental noise and monitoring needs, achieving the optimal balance between safety and clarity.
Not only complies with international telecommunication safety standards but also effectively reduces auditory stress and fatigue for users during long periods of high-pressure work.

Ergonomics and Structural Design

Specially shaped cable and connector design aims to completely eliminate structure-borne noise caused by cable movement, ensuring monitoring purity.
The split headband easily conforms to various head shapes, effectively distributing pressure to maintain stability and comfort even during prolonged wear.
All critical contact parts, such as ear pads and cables, are modularly designed and can be easily and quickly replaced by the user, significantly extending the product's lifespan.
