- Product Details
The SE-Master1 features the industry's first aluminium diaphragm with ceramic coating. The lightweight, 25µ-thick aluminium diaphragm is treated with a ceramic coating to add rigidity, enhance its natural performance, and deliver excellent sound quality. The result is high resolution sound across all frequencies with minimum noise. The diaphragm's edges are ribbed and made with a sturdy poly-ether-ether-kotene (PEEK) file to deliver a smooth sound and reduce distortion. Pioneer headphone specialists used computer aided engineering(CAE) to select, prototype and test the best materials for the diaphragm and magnetic circuits, ensuring superb sound characteristics and clarity. The SE-Master1 is capable of reproducing high-resolution audio of up to 85kHz, more than double the minimum requirement for high-res headphones(40kHz). So you can experience every unadulterated detail of your high-res music.
Originally developed for car speakers, the full basket system reduces resonance while delivering an energetic sound. The speaker unit is firmly secured using aluminium and the base is finished with ASA resin, which adds excellent weather resistance. Rubber is inserted in the links between the base, housing and hanger parts to prevent vibrations and interference. Inherited from the speaker ranges, this floating structure also improves separation between left and right to deliver an enhanced sound stage. 3.5mm-thick aluminium alloy housing minimizes resonance from the driver units to produce an accurate sound with a clearly defined, tight bass and high-res mids and highs.
The headband and hanger parts use a super duralumin alloy to achieve a light, natural fit that lets you forget everything but the music you're immersed in. The wide, suede-feel head cushion can be adjusted to 14 different positions, giving you excellent comfort and stability. Innovative three dimensional ear pads adapt to fit your contours thanks to a proprietary design using two thicknesses of memory foam - thin at the front and thick at the back. The ear cups are covered with a soft leather-type material for extra comfort.
The SE-Master1 features the industry's first detachable lateral pressure rods, enabling you to choose your preferred headband tension. Simply change the tension rod to achieve strong or weak lateral pressure and enjoy superb sound isolation and comfortable wear over long periods. The robust cord uses a detachable MMCX type connector so you can replace the cord as needed. The cord is cloth-wrapped between the plug and the branch, and coated with lead-free PVC from the branch to the ear cup - to reduce touch noise, increase strength, and eliminate tangles.
