Background Story

R4’s unique design language hails from such elements as cyberpunk, mecha, and space opera. Clear-cut powerful geometric lines cross to form the silhouette of a living, breathing audio machine, with the offset hatch design on the back adding to the motif of a retro classic set in the distant future.

DESIGN CONCEPT

A sturdy lanyard lug coupled with the graffiti-designed lanyard makes for a striking appearance as well as practical usability in outdoor / active scenarios–the quest for an appealing, youthful outlook follows practical considerations to yield a form that is at once instantly recognizable and suitable for a wide audience.
Note: the strap is not included in the standard packaging. Please purchase the strap separately.
