PreSonus “Eris 3.5BT” (Gen 2) 3.5-inch Desktop Speakers with Bluetooth

While they may not have the eye-catching looks of something like those bamboo Audioengine A5+ speakers, the second-generation Eris 3.5BT studio monitors from PreSonus are arguably the better buy for most people, purely in terms of value for the money.

Designed for use in the home studios of music/video producers or in high-fidelity gaming/entertainment setups, the Eris 3.5BT v2’s deliver outstanding, clear sound across the frequency range, from rich, booming lows to bright, refined highs.

They can get real loud before you notice even a hint of distortion, so even professional musicians carefully mixing their next hit can feel confident in the accuracy of the audio reproduction.


In addition to a few different physical inputs — ¼-inch TRS and RCA inputs on the back, ⅛-inch stereo line on the front — the monitors also feature fast and reliable Bluetooth 5.0 connectivity so you can easily, say, pair your iPhone and listen to podcasts.

Here are the other feature specs for audio nerds to look over:

  • 3.5-inch, woven-composite, low-frequency transducer
  • 1-inch (25 mm), ultra-low-mass, silk-dome, high-frequency transducer
  • 50W (25W/side) Class AB amplification
  • 80 Hz to 20 kHz frequency response
  • 98 dB SPL (Peak, @ 1 meter)
  • High- and low-frequency Acoustic Tuning controls
  • Balanced, ¼-inch TRS inputs; unbalanced, ⅛-inch stereo and RCA inputs; and integrated stereo headphone amplifier with front-panel ⅛-inch output
  • Protection: RF interference, output-current limiting, over-temperature, turn-on/off transient, subsonic filter

You can get the Eris 3.5BT Gen 2 studio monitors for $150 on Amazon.
