PreSonus Eris 3.5BT 3.5" Bluetooth Studio Monitors (Pair)
The PreSonus Eris 3.5BT is a pair of 3.5-inch studio monitors with Bluetooth 5.0, built for the desk where everything happens: listening to music, editing video, gaming and starting to produce. It replaces tinny computer speakers with neutral sound, without taking up more room than a stack of books.
What sets it apart
- 3.5" woven glass fibre woofer and 1" silk-dome tweeter
- 50 W of Class AB power, or 25 W per side
- Four ways to connect a source, including Bluetooth 5.0
- Front-panel headphone output, with volume on the same knob
Small format, honest sound
Each speaker is 21 cm tall, 14.1 cm wide and 16.4 cm deep, so the pair fits on either side of a screen without hanging off the desk. PreSonus rates the response at 80 Hz to 20 kHz with a 98 dB peak at one metre, plenty for close-range listening.
Two rear controls, high and low, trim the sound of an overly bright room or a desk pushed against the wall by ±6 dB. Set them once and your reference stays the same from one project to the next.
Everything plugs in, even your phone
Balanced 1/4" TRS inputs for an audio interface, RCA for a turntable or mixer, a 1/8" mini-jack for a portable player, and Bluetooth for your phone: nothing to unplug when you switch sources. The specs on this page are for the 2nd generation, the model PreSonus sells as a pair today.
