Eris monitors from PreSonus have gotten a good name in the studio and music production worlds. The E7XT, for example, is a great monitor choice for small to medium-sized studios with a mid-range budget. The company’s smaller Eris monitors, like the Eris 3.5 we’re testing here, are called “media monitors” by PreSonus. This means that they’re great for music fans and people who make their own content.
The other media monitor in this category is the 4.5-inch one, which is bigger (with a larger 4.5-inch driver, one inch bigger than the 3.5). There are also Bluetooth versions of both speakers called Eris E3.5 BT and 4.5 BT. Both the design and the specs of these speakers are the same. The only difference is that Bluetooth 5.0 and a wired input have been added.

Where to get PreSonus Eris E3.5?
Even though it is a small and inexpensive PreSonus monitor, the Eris 3.5 has some of the design know-how from the larger studio/pro models in the Eris range. You get a Kevlar driver, which is a great addition for punchy playback, and the same solid vinyl-laminated fiberboard enclosure, which is made to give you a rigid response and less vibration and distortion. But that’s about all they have in common.
For example, the 3.5s have the amplifier in the left speaker, and the right speaker is powered by a cable. It’s a common way to set up speakers that are small enough to fit on a desk.
On the back of the left Eris 3.5, there are a TRS jack and an RCA jack. The front of the same speaker has a headphone out and a stereo mini jack for smartphones and other devices. These options for connecting make these speakers a great and useful choice for listening to music in a casual setting. You don’t get an XLR input like on the higher-end Eris models, though.
These are designed for quality desktop use, not recording in a professional studio. You do have volume, power, and a headphone out on the front panel, which is also helpful. Also on the left unit are controls for high and low frequency. These help you tune the monitors to your room and where you put them. For example, if you put the speakers too close to a wall, you may need to change the bass response.
