Overview

The PreSonus Eris E3.5 nearfield studio monitors are designed for creators and listeners who need accurate, detailed audio in a compact desktop form factor. Each speaker houses a 3.5-inch woven composite woofer that delivers controlled low-end reproduction with minimal distortion, paired with Class AB amplification totaling 50 watts (25 watts per speaker). This power configuration provides enough volume and dynamic headroom for critical listening, mixing, and casual media playback in a nearfield setting without overwhelming a small room.

Connectivity is a genuine strength of the Eris E3.5. The monitors offer balanced 1/4" TRS inputs for professional audio interfaces, RCA inputs for consumer gear, and a front-panel 3.5mm aux input for quickly connecting a phone or media player. Rear-panel acoustic tuning controls let you tailor the frequency response to your specific room and placement conditions — a feature that's uncommon at this price point and genuinely useful for getting the most accurate sound from a less-than-ideal desktop setup. This particular bundle extends the value proposition by including an RGB backlit keyboard, gaming mouse with adjustable DPI, mouse pad, and stereo headphones with a built-in microphone, offering a ready-to-go workstation package for creators and gamers alike.
