The PS500 Dynamic Circumaural Open Air Stereo Headphones, part of Grado's Professional Series, are an ultra-high-quality set of circumaural, open air headphones. The proprietary hybrid earpieces use a hand-crafted mahogany inner sleeve and a non-resonant aluminum outer housing to eliminate transient distortions and reflections, ensuring that every audio detail comes through. The adjustable leather headband ensures maximum security and comfort while listening.

Specially-designed drivers are matched to within 0.05dB and offer an ultra-wide frequency response of 14Hz to 29kHz. The drivers work together with the housings to provide great control over all frequency ranges. The ultra-high purity long crystal copper (UHPLC) voice coils and 15-wire UHPLC connecting cable provide a clear signal path and excellent control over upper and lower frequencies. The result is clear, realistic sound that's perfect for any musical genre.
