Pioneer SE-MASTER1. Open-back High-End headphones.
Meticulous attention to even the finest detail was given to the production of the SE-MASTER1. Each unit is assembled by a master craftsman at the Tohoku Pioneer plant in Japan; the birthplace of many iconic speaker models. They pour their advanced technological know-how into every step of the journey-from design to production and quality control- so your headphones deliver excellence without compromise.
The industry’s first aluminum diaphragm with ceramic coating
The lightweight, 25μ-thick aluminum 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.
Optimum sound quality achieved using computer aided engineering
Pioneer 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.
Full basket system delivers an energetic, low-resonance sound
Originally developed for car speakers, the full basket system reduces resonance while delivering an energetic sound. The speaker unit is firmly secured using aluminum and the base is finished with ASA resin, which adds excellent weather resistance.
Aluminum housing ensures tight bass and clear mid and high frequencies
3.5mm-thick aluminum 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.
Cushion for added stability
The wide, suede-feel head cushion can be adjusted to 14 different positions, giving you excellent comfort and stability.
Interchangeable tension rods to eliminate wearer fatigue
The SE-MASTER1s feature 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.
Rigid diaphragm edges eliminate distortion
The diaphragm’s edges are ribbed and made with a sturdy poly-ether-ether-ketone(PEEK) film to deliver a smooth sound and reduce distortion.
Superior high-resolution playback
The SE-MASTER1s are capable of reproducing high-resolution audio of up to 85,000Hz, more than double the minimum requirement for high-res headphones(40,000Hz). So you can experience every unadulterated detail of your high-res music.
Floating structure for low distortion and clear sound separation
Rubber is inserted in the links between the base, housing and hanger parts to prevent vibrations and interference. Inherited from our speaker ranges, this floating structure also improves separation between left and right to deliver an enhanced sound stage.
Lightweight build and natural fit
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.
Snug fitting, soft ear pads for extra comfort
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.
Detachable, robust, tangle free cord
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.
