After more than five years in development, Pioneer unveils the SE-MASTER1 reference-class headphones enrich any musical performance without compromise. With a battalion of technological innovations the new flagship reference headphones achieve pure and precise sound reproduction.

With 50mm driver units and powerful magnetic forces at its core, the SE-MASTER1 brings you as close to the original recording as possible. High-resolution audio playback gives an extra dimension to your music and adds a sense of reality by expressing both sound and space. With an upper limit frequency of 85kHz these exceptional headphones fulfil the demands for reference level audio.

Each pair of SE-MASTER1 is handcrafted at Pioneer's Tohoku plant in Japan. Several innovational design features include aluminium diaphragm with a ceramic coating for extra rigidity, ribbed diaphragm edges for reduced distortion, memory foam earpads.

Premium Materials
The SE-MASTER1’s aluminium housing and full basket system with low-resonance floating structure, make sure that unwanted vibrations cannot interfere with the music. At the same time, it enhances the separation between left and right to deliver an enhanced soundstage.

AIR Studios Certification
London’s renowned AIR Studios have rigorously tested and tuned these headphones to achieve pure and precise sound reproduction. Carrying their seal of approval, the SE-MASTER1 now is the world-first AIR Studios Monitor Reference Headphones.

Advanced Design
The 25µm aluminium diaphragm is finished with a Parker Ceramic Coating (PCC), which improves accuracy in the high frequencies, pushing the audio performance to a higher level. In addition, the PEEK (Poly-ether-ether-ketone) compounding material helps to reduce distortion, achieving an even smoother sound quality.

All materials for the SE-MASTER1 are carefully selected for their qualitative characteristics and beauty. With great attention to detail, each unit is handmade by a single certified craftsman in Tohoku Pioneer’s Tendo factory in Japan, and will be engraved with its own serial number.

Maximum Comfort
The SE-MASTER1 has soft-leather, 3D earpads with flexible memory foam for a perfect and snug fit. The suede-feel head cushion, light aluminium hanger and a detachable tension rod are designed to reduce the weight of the headphone to further improve your comfort, even during long listening sessions.

Perfect Match
Combine the SE-MASTER1 with the JCA-XLR30M cable and the U-05 headphone amplifier to achieve optimal sound. Thanks to the 3-pin XLR connection, high-grade audio is guaranteed.
