  • 64 Audio Duo

    Refurbished unit in excellent condition repackaged with original accessories or accessories from compatible models and brands. All refurbished products are certified by authorized technicians and come with a 90-Day warranty.

    Duo is 64 Audio’s latest universal in-ear monitors with dual driver hybrid design. Duo offer an open back experience with the intimacy of an in-ear monitor. Built with the complete Tia System, Apex Core, Wave Sync, and LID, Duo presents 64 Audio’s signature balanced sound in a whole new way. The simple audio design captures the listener’s auditory senses while forgetting they’re wearing IEMs in the first place.

    The complex faceplate assembly not only serves an important role in protecting the shell of the IEM while allowing air to flow freely, it is also a major step in 64 Audio’s product design evolution. Duo is a timeless and elegant design reminiscent of open-back over-ear headphones.

    Duo feels light, leaving your ears feeling open and relaxed even for long listening periods. You feel simultaneously connected to your physical surroundings while you’re enveloped by music. Relaxed tonality lets you put them on and get lost. It’s able to present a non-analytical top-end while retaining air and sizzle. The vast open air sensation supports an unobstructed soundstage with impactful centre imaging (unlike many other open back headphones) as well as no loss of bass. Duo effortlessly produces deep and rich low frequencies with plenty of sub bass.

    Get closer to your music.

    64 Audio Duo Hybrid IEM Earphones

    TIA System
    Rather than constricting the sound of the drivers by fitting a tube onto them, Duo’s complete Tia System reduces unwanted resonance and distortion by allowing the 9mm Dynamic Driver + Tia High Driver to radiate freely into the single large Tia bore with no obstructions to the front of the drivers.

    Apex Core
    Apex Core is a deeper understanding of air movement within an earphone system. Duo’s faceplate features a striking perforated grill that leaves the shell of the IEM open to the outside atmosphere for a less obstructed airflow resulting in an effortless reproduction of music and minimal physical fatigue.

    Wave Sync
    Due to the high crossover point between the two drivers, Wave Sync was developed to ensure coherence; another industry first. By using a type of 'all-pass”'filter, 64 audio are able to introduce a crossover while correcting for time without having to change the physical distance between the drivers.

    Linear Impedance Design
    LID Design, enables a consistent, reliable sound regardless of what source. This proprietary circuit corrects the non-linear impedances of the drivers, restoring proper interaction with the source and preserving the desired sound signature. LID ensures your IEMs are delivering the desired sound signature consistently.
