Know before you buy
The RS ONE is built with a high-strength polycarbonate body that is resistant to heat, sweat, and impact, making it durable enough for active stage use. Its long-stroke driver mechanism is specifically designed to handle high-volume sound environments without distortion.
Yes, the RS ONE is designed for both professional monitoring and everyday high-fidelity listening. Its low impedance of 32 ohms ensures it can be driven easily by standard devices like smartphones, laptops, and tablets without needing a dedicated amplifier.
The Pentaconn Ear connector is a high-reliability interface that provides a more secure and durable connection than standard MMCX or 2-pin connectors. It is designed to minimize signal loss and withstand the frequent cable swaps often required in professional environments.
No, the RS ONE uses passive noise isolation. By achieving a proper seal in your ear canal with the included tips, the physical design of the housing blocks out external ambient noise.
The included ARM011 cable features Kevlar shielding, which significantly increases its tensile strength and resistance to tangling. This makes it much more resilient against the wear and tear of daily use or professional stage movement.
