A quad driver hybrid UIEM featuring ground-breaking patented technologies originally developed for our flagship products in order to bring a wider audience closer to their music. U4s explores a bold new color aesthetic for 64 Audio. The Slate Blue shell color was influenced by some of the world’s most beautiful blue- dial timepieces while the unique faceplate pattern is inspired by Muonionalusta meteorite fragments. Both the faceplate and shell’s illuminant properties give it a unique tone in varying lighting conditions.

Joshua ★★★★★

Been using these daily for my commute and the hybrid setup handles both acoustic and bass-heavy tracks without muddling anything. Vocals sit nicely forward, and the shells are lighter than they look, so hour-long listening sessions don't bother my ears.

Zoe ★★★★★

The quad driver setup really shows on acoustic tracks — I'm hearing layers in the strings I never noticed before. They're chunky in the ear but the fit is solid once I found the right tips.

Andrew C. ★★★★★

I've been using these with the stock foam tips and the bass from the quad driver setup is genuinely impressive without drowning out the mids. The hybrid design keeps vocals clean even on busy rock tracks.
