Alessandro Grado MS-PRO Heaphones.

Alessandro Grado MS-PRO Headphone is a special modified Grado RS1e for musicians/pro users. Please note that this contains the latest driver version "X" model.

The wooden Music Series Pro model is hand-crafted at our labs from a specially selected species of mahogany. An intricate procedure of curling is done between production steps to achieve optimal sonic quality. The overall sound remains pure, warm harmonic color, full bodies vocals, excellent dynamics and an ultra smooth top end. The Music Series Pro model also utilize UHPLC in its connecting cable.

Alessandro High-End Products and Grado Labs have combined their design capabilities to create a new line of headphones. The Music Series headphones focuses on the needs of the music industry. Each model has been specificly tuned to produce extra ordinary results at their respective price points.

Superior Design & Precision
All Music Series headphones have a vented diaphragm design that incorporates a large air chamber. This design lowers the frequency resonance (distortion) of the diaphragm and extends bass response. A unique process to de-stress the diaphragm results in enhanced inner detail. The diaphragm is made of a low mass polymer, carefully formed to broaden resonant modes to reduce their amplitude. The diaphragm's total mass is calculated to provide a full 20 KHZ bandwidth while avoiding breakup at lower frequencies.

The Music Series One, Two and Pro headphones all feature voice-coils that are wound from ultra-high purity, long crystal (UHPLC) oxygen free copper. Ultra-high conductivity copper yields the clearest transmission and lowest coloration possible. This combined with high power neodymium magnets provide maximum efficiency giving a smoother, cleaner and more dynamic sound and a larger perceived sound stage.
