      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.
