Luxury-class in-ear monitor
With the Duo, the established US manufacturer 64 Audio presents a universal-fit two-way in-ear monitor with an open design for intense musical enjoyment. With a hybrid system comprising one dynamic driver for the bass and one balanced-armature driver for the treble range, complemented by the innovative tia system with its completely tubeless design, the LID (linear impedance design) system for a consistent sound, and the Apex Core and Wave Sync technologies, the Duo offers its users a balanced, wide sound stage with an extra dose of openness. A wide selection of foam and different silicone earpieces in three sizes each, a detachable cable with a 3.5 mm mini-jack connector, and a high-quality leather case are also included in the scope of delivery.
With tia and Wave Sync
With the tia system, the Duo has a completely tubeless design, which means that instead of using tubes to guide the sound to the listener's ear and thus obstruct it, the dynamic 9 mm driver and the BA-tia driver send the sound unhindered into the so-called "tia bore". In this way, the system creates an organic listening experience by reducing distortions and resonances detrimental to the sound that would otherwise normally occur. With the Wave Sync system, the two drivers are also perfectly matched to each other. This is achieved by using a kind of all-pass filter, which takes over the function of a frequency crossover and at the same time corrects the time offset without having to change the driver distance.
Pure high-fidelity experience
Apex Core is a unique ventilation system that leaves the Duo's casing open to the outside. The perforated grille on the front panel allows airflow to spread more easily, resulting in improved playback and fatigue-free listening. The Duo thus delivers an extremely appealing sound that is more reminiscent of open over-ear headphones than in-ear monitors. With a compromise-based ambient noise reduction of -12 dB, the Duo is designed less for use in on-stage monitoring and recording room applications, and more as an ideal choice for all music lovers, hi-fi enthusiasts, and audiophile users who want to call an open-sounding high-fidelity in-ear monitor their own.
About 64 Audio
64 Audio is a US company from Vancouver, Washington, consisting of around 70 employees and founded by Vitaliy Belonozhko, which has developed into a globally respected manufacturer of premium-quality in-ear monitoring systems. With future-oriented innovations such as tia, apex, and LID, the premium in-ear monitors included in the range outperform traditional technologies. In addition to the universal "off the shelf" in-ear monitors with foam and silicone ear tips in different sizes, 64 Audio also offers custom-made in-ear monitors, for which a new, digital process called 3D-Fit is used instead of the conventional moulding process. Many famous show stars already rely on the IEM systems from 64 Audio.
Music enjoyment wherever you are
Thanks to the Apex Core, the Duo combines an open headphone experience with the capabilities of an in-ear monitor system. No matter if you are at home and connected to your high-end audio system in the living room in order to pay full attention to your favourite artist’s record and immerse yourself completely in the music, or in public and connected to your smartphone in order to wind down at the end of the day by listening to your personal Spotify playlist while travelling home on the train or by bus: Thanks to the LID system, the Duo always delivers a high level of sound consistency completely independent of the playback device. In addition, the over-ear cable design, the ergonomically designed casing, and the large selection of earpieces ensure that the in-ears will fit securely with a high level of comfort.
