Sound you can trust.
PreSonus® Eris-series 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 employs the same technology as the larger Eris models to deliver studio-quality sound, with a smooth and accurate frequency response. Yet they're compact enough to fit almost anywhere.
Woofers that deliver a cleaner overall sound.
Every Eris ® -series studio monitor uses a woven composite, low-frequency driver. The weave and nature of the Eris E3.5's 3.5-inch woofer result in a more constant dispersion pattern throughout the frequency range, resulting in less time-smeared audio and cleaner overall sound.
Smooth high end and wide sweet spot.
The Eris E3.5 is equipped with a one-inch silk-dome tweeter that produces a smooth and refined sound, accurately reproducing transients and high frequencies. The tweeter is designed to radiate sound with a fairly wide dispersion pattern, creating a large optimal listening area or “sweet spot” so you can move around and still hear everything accurately.
Easy-to-use controls.
A speaker's response is affected by where you place it and the acoustics of your space. That's why Eris E3.5 active media reference monitors offer easy-to-adjust high- and low-frequency controls. A convenient front-panel volume knob sets both the speaker level and the integrated headphone amplifier level. Be careful with that volume knob, though: Eris E3.5s are driven by an onboard 25 watt / side power amplifier and can get a lot louder than you may expect, while still delivering clear, accurate audio.
Connect to virtually any line-level source.
With three different types of audio inputs, it's easy to feed audio to your Eris monitors from a mixer, an interface, a media player, or almost any other line-level source. The Eris E3.5 is equipped with rear-panel, ¼-inch TRS and RCA inputs, as well as front-panel, ⅛-inch, stereo unbalanced line inputs for use with mobile audio devices. With this selection, you'll have no problem hooking your Eris speakers up with virtually any line-level source, including your smartphone or tablet. The loud, clear, front-panel headphone amplifier lets you work and play in stealth mode without disturbing your housemates.

Accuracy defined.
Like all PreSonus ® monitor speakers, the Eris E3.5 offers consistent, accurate listening, with the smooth and even frequency response that has made Eris monitors popular around the world. Their compact and powerful design makes them an ideal solution for any small space.

...leaps and bounds above others in their range... deliver quality quite unlike anything you could expect from such a compact, low-price solution…above and beyond expectations in virtually every regard.
Dexter Jones, DJ Tech Reviews
I am in love with the PreSonus Eris E3.5 studio monitors and there is nothing you can do to break us apart.... They make other monitors in this class take a back seat in comparison.
Scott Winstead, My eLearning World
Great media monitors, then, ideal for video mixing, Youtubers, gaming and budget music production, and the price is verging on the ridiculous.
Andy Jones, MusicRadar
The accurate sound and excellent frequency balance make it a perfect option for recording and mixing.
K.M. Joshi, Integraudio
These things are pretty dope because they gave me the flat response I was looking for.
Kevn Elib, Kreatve Snd
The perfect balance of size, sound quality, frequency profile, and aesthetics to produce some phenomenally accurate sounding speakers at a stupid price point.
MainByte
It was an absolute joy to use these speakers when producing, as all of the sound was clear and accurate…. The imaging is also great.
William Pickard, BubVisuals
I think you really can’t go wrong; if you are setting up a home studio, if you’re on a budget, if you’ve got about $100 to spend on a pair of speakers, these are what I would buy.
Pete Johns, Studio Live Today
If you have a really small room or you’re tight for space…these are definitely the ones to get.
I'm a Music Mogul
These suckers blew me away, easily the best speakers I’ve heard in this price range.
Jack Vania, Techvania
...the greatest speakers for editing on a budget…. I know it sounds like I’m gushing over these speakers but they really are that good.
Israel Sanchez, All Around Filmmaker
The low price point is unbelievable for the quality you get.... truthful sound with an accurate frequency response.... I actually couldn’t’ believe how much bass these little drivers produce.
Nicholas Cole, Gear Seekers
...truly astounding....very hard to beat for the money (even for twice the price, or more). I'd give Bang for Buck at least six stars if I could.
Dennis Wilkins, Gearspace
...serious speakers with an excellent punch. Both models are fantastic, but if you want the best, get the E4.5s, you won’t be disappointed.
Indiana Lang, Secrets of Home Theater and High-Fidelity
I could feel and hear everything and given that the monitors seem to project a nice wide stereo field the sound did not change as I moved side to side…. the PreSonus sound encouraged me to sit there and play for ages.
Nigel Cooper, RedSharkNew
...detailed and clear sounding... big enough to do some serious work.
DrAudioBot, Gearspace
The Eris E3.5 worked great as I have them in my control room as a secondary pair of stereo monitors but they would be good as stereo monitor speakers for playing video games or for a small keyboard synth setup.
Barry Rudolph, New Toys
... idealny kompromis dla osób, które oczekują studyjnej jakości dźwięku w domowych warunkach, przy czym nie posiadają wiele miejsca.
Michal Morawski, TechManiacHD.pl
À l’instar des Eris E8, les 3.5 nous ont vraiment séduites.
Red Led, Audiofanzine
What you hear is what you get with this monitors.

".. don’t let the low price fool you, these are serious speakers with an excellent punch."

"Was mir bei der ERIS E3.5 BT dennoch an Klangqualität entgegen schallt ist in dieser Preisklasse absolut phänomenal."
Patric Louis, Bonedo.de
PreSonus has created one of those rare gems that everyone should own, and they’ve made it quite accessible regardless of your financial situation.
