The over-ear Sennheiser HD 599 SE (Special Edition) headphones are a special version of the legendary 500 series from the German brand. Designed for demanding audiophiles and home sound enthusiasts looking for uncompromising comfort and natural, spacious sound. The main difference between the Special Edition (SE) version and the classic HD 599 model is the premium, strict execution in completely black color instead of the traditional cream-brown color.
At the heart of the headphones is the trademark open acoustic design with E.A.R. (Ergonomic Acoustic Refinement) technology. This engineering concept directs the audio signal from the custom 38mm dynamic drivers at a carefully calibrated angle directly into the listener's ear canals. This solution, combined with open ear cups, minimizes internal resonances and creates an incredibly wide, natural, and immersive soundstage. Musical instruments and vocals are positioned very realistically, creating the effect of being present at a live concert.
The headphones have a balanced frequency response with soft, velvety bass, detailed midrange, and clean, non-fatiguing high frequencies. With an impedance of 50 ohms and high sensitivity (106 dB), the HD 599 SE headphones are versatile: they perform excellently when connected to stationary Hi-Fi systems and sound cards, as well as when used with high-quality portable DAC/amplifiers.
The model's ergonomics are perfected. Large, velour-covered over-ear cushions and headband with leather finish evenly distribute the lightweight of the headphones (only 250 grams). This completely eliminates pressure on the head, allowing for extended listening sessions, sound work, or gaming without any hint of fatigue.
