    Overview

    Exploring new frontiers and experimenting with new driver technologies led Pioneer to the creation of the SE-MONITOR5. Featuring a custom-made 50 inch driver created from organic wood pulp and a cellulose nano-fiber transducer, these headphones can transmit frequencies from 5Hz to 85 kHz. Optimal for music and production studios, these headphones have been created to deliver Hi-Res Audio.

    Assisting the transducer to achieve the best sound performance the base and housing are constructed from a super-rigid magnesium alloy. Delivering clearly defined bass with accurate spatial sound placement, you can enjoy true-to-source audio. Supporting both balanced and unbalanced audio, three cords are included; two unbalanced bi-wire cords with 3.5 millimetre stereo connectors and one balanced cord with a 2.5 millimetre 4-pole stereo plug. With the balanced cord, you can savour enhanced stereo separation, taking your audio to new heights. And with 3D memory-foam earpads wrapped in soft material, you can wear these Over-Ear Headphones over listening sessions.
    Cellulose Nano-Fiber Wide-Spectrum Driver

    Rather than using previously-developed driver technology, Pioneer fused biology with technology to create this cellulose-based nano driver. Capable of reproducing frequencies between 5Hz and 85 kHz, you can enjoy rich Hi-Res Audio.

    Hi-Res Audio

    This unit is a Hi-Res Audio device, which allows it to play a variety of 24-bit digital audio formats. This simply means you can take full advantage of high-quality audio sources like FLAC audio files.

    Built To Eliminate Distortion

    With a magnesium-alloy base and housing, unique-dual chamber system, diffuser technology, and floating structure, these headphones deliver clear sonic sound without distortion or resonance.

    Balanced and Unbalanced Audio Support

    With support for both balanced and unbalanced audio cables, you can choose how you wish to listen at any given time. Whether you want the enhanced left and right separation of the balanced cable, or the convenience of the unbalanced, these headphones have got you covered.
