Brand: Usher audio
The Usher Audio P-307A is a high-performance planar magnetic headphone designed for audiophiles and studio professionals. It features a large 106mm (4.17 inches) diaphragm with a unique dot-matrix structure, which helps to reduce reflections and diffractions, resulting in improved imaging and accuracy. The headphone also has a proprietary high-purity LID (Light Inducing Diaphragm) with True Geometric Waveguide technology, which enhances transient responses and micro-detail retrieval. The P-307A also uses Usher's Optimized Graphene nanocomposite (OGNC*) driver diaphragm, which provides a smoother response, increased resolution, and lower distortion. The headphone has a frequency response range of 18Hz to 40kHz and a sensitivity of 90dB. The P-307A comes with a detachable 2m (6.6ft) OFC (Oxygen-free copper) cable with dual 4-pin XLR connectors and a gold-plated 1/4 inch (6.35mm) adapter. The headphone comes with a high-gloss black hard case for storage and transport.
