Eris 3.5BT media reference monitors
PreSonus® Eris®-series studio monitors are used worldwide by audio engineers and producers who need to hear every detail of their recordings. Eris 3.5BT 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 setups.
With 25 watts per side of onboard power, Eris 3.5BT reference monitors pack a serious low-end punch, while still delivering clear, accurate audio.

Standout Features
VERSATILE CONNECTIVITY.PreSonus® Eris® 3.5 BTs connect wirelessly using Bluetooth® 5.0 or via a wired connection to virtually any line-level audio source, using rear-panel ¼-inch TRS and RCA inputs and a front-panel, ⅛-inch stereo line input. You also get a convenient (and loud!) front-panel, ⅛-inch stereo headphone jack; connecting headphones mutes the speakers.
BUILT TO MATCH YOUR ROOM.Unlike other home audio speakers that hype the bass at the expense of other frequencies, Eris® speakers provide an even response throughout the frequency range, from bass to treble. This means you’ll hear your favorite music exactly as artists and engineers intend it to be heard. High and Low Acoustic Tuning controls let you dial in the Eris 3.5 BTs precisely to your environment to further ensure the best sound possible.
HONEST. EXPRESSIVE. POWERFUL.Like all PreSonus media reference monitors, the Eris® 3.5 BT offers consistent, accurate listening. Their stylish design makes them a welcome addition to living rooms, compact home theater setups, and gaming rigs, and their smooth and even frequency response ensures that your music — and everyone else’s — will sound incredible.
