PreSonus® Eris®-series studio monitors are used worldwide by audio engineers and producers who need to hear every detail of their recordings. Eris 3.5 media reference monitors deliver studio-quality sound in an elegant, compact form factor that makes them ideally suited for bedroom studios, video production, and high-fidelity gaming set-ups.
