High-Performance IEMs

Packing a whole lot of tech into a compact, metallic-blue package, the Optoma NuForce Primo8 delivers a bright, clear sound and an extremely secure fit. Along with a convenient detachable cable, the IEMs come with a treasure chest of accessories: 10 pairs of eartips, a gold-plated quarter-inch adapter, and a silky microfiber cleaning cloth, to name a few.

NuForce Primo8 Earphones

Clear Sound, Convenient Features

The Primo8’s resin shell and metal inner layer minimize vibrations for a crisp audio experience, and the ear hangers can be shaped to your ear for personalized comfort. Inside each earphone, four balanced armature drivers, arranged in a three-way crossover design, produce a natural, fully dimensional soundstage with excellent dynamics. The 4.6-foot, tangle-free cord features a smartphone-compatible inline remote, so you can skip tracks and answer calls with ease.
