Description
Planar Precision for Professional Listening
Planar drivers move air with speed and uniformity, allowing R34 to reproduce subtle dynamics with exceptional control. From vocal takes and guitar layers to low-end balance and reverb tails, R34 is tuned to present music with clarity and discipline so you can make confident decisions while recording, mixing or monitoring.
Designed for Long Sessions
Reference sound only matters when the headphone stays comfortable and consistent. R34 is shaped for extended listening sessions with a secure over-ear fit that helps maintain positioning, seal and stability over time. Whether you’re working through a full mix, rehearsing, editing or simply listening critically, R34 is built to stay comfortable without distracting from the sound.
Interchangeable Connector Compatibility
R34 is designed with interchangeable connector support, giving professionals the flexibility to adapt the headphone to different systems, cables and workflows. Choose from three connection types - 3.5mm, 1/4" and 4.4mm balanced - to move easily between portable devices, studio interfaces, headphone amplifiers and balanced audio setups without replacing the headphone itself. This modular approach keeps R34 versatile, serviceable and ready for the way you work.
Built for Musicians, Not Hype
R34 is not tuned to impress with artificial bass or overly sharp treble. It is designed to support the way musicians and professionals actually listen — focused, balanced and repeatable. The result is a headphone that helps translate creative intent with accuracy, while still delivering the scale and immersion that makes planar headphones special.
Fit-First Sound™ Philosophy
R34 brings ADV.’s Fit-First Sound™ philosophy into a full-size planar headphone. By combining reference-focused tuning with a fit designed for real-world use, R34 gives musicians and creators a dependable tool for hearing more of what matters in every performance, mix and session.
