PreSonus Eris E3.5 BT studio monitors are used worldwide by audio engineers who need to hear every detail of their recordings. Ideal for gaming and home video production, the Eris E3.5 BT employs the same technology as the larger Eris models to deliver studio-quality sound, with a smooth and accurate frequency response in a compact format.

Designed for a clean overall sound, smooth high end and a wide sweet spot, the Eris E3.5 BT monitors utilize a woven composite low-frequency driver. The weave and nature of the Eris E3.5 BT’s 3.5" woofer result in tight bass that you can feel, as well as cleaner overall sound. The 1" silk-dome tweeter produces a smooth and refined sound, accurately reproducing transients and high frequencies. The tweeter is designed to radiate sound with a fairly wide pattern, creating a large optimal listening area, or “sweet spot,” so you can move around and still hear an accurate stereo image. With 25 watts of onboard power per side, the Eris BT-series monitor speakers pack a serious punch, while still delivering clear, accurate audio. With four different types of audio inputs, it’s easy to feed audio to your Eris E3.5 BT monitors from almost any source.

Fast, reliable, stereo Bluetooth 5.0 connectivity lets you go wireless, streaming sound from a smartphone, tablet, laptop or other Bluetooth source. When you want a wired connection—say, from a computer, turntable, TV or other line-level source—the Eris E3.5 BT has you covered, with rear-panel, left and right 1/4" TRS and RCA inputs and front-panel 1/8" stereo inputs. A loud, clear, front-panel headphone amplifier lets you work and play in stealth mode, without disturbing neighbors or housemates.
