What Real Users & Reviewers Are Saying
- MusicRadar praises the Eris 3.5 for its detailed sound and exceptional value—calling it a great desktop speaker.
MusicRadar - Higher Hz is more critical, saying: “Not exactly studio monitors… best used as computer speakers—not ideal for mixing or mastering.”
Higher Hz - On Reddit, one user noted the frequency tuning didn’t counter the boom around 130 Hz: “Extremely boomy around 130 Hz… EQ knobs don’t affect that frequency.”
Reddit - Another shared: “Good enough for casual listening… absolutely not for mixing. Way too colored response.”
Reddit - From Sweetwater: “Surprisingly full sounding for such a tiny speaker. Great for office or desktop—but not a top choice for serious mixing.”
