The volume on my phone was set to around 50%, which is a pretty good level for testing speakers. I tapped play on “Analog Kid” by Rush and was punched in the face with a wall of sound.
I hadn’t expected such volume from a small speaker, but there it was. You’d have thought my phone was cranked to 11, and the band was right in front of me playing live.
I quickly grabbed my phone and turned down the volume to roughly 25%, but the speaker was still pretty loud. Next, I opened my decibel meter, cranked the volume back to 50%, and the meter read 86 decibels.

According to Decibel Pro, “85 decibels is a high noise level on the decibel scale. It is 15 times more intense than the 70-decibel level considered by the World Health Organization (WHO) and Environmental Protection Agency (EPA) safe for human hearing.”
So, yeah, it’s loud. I didn’t test the decibel reading with the phone at 100% volume because my cats would probably never forgive me.
Okay, enough with the decibels.

Going through my usual test playlist, what jumped out at me (even with my custom EQ curve) is that there’s not a lot of definition to the various frequencies. Although that’s fairly typical when dealing with such a minimal equalizer, it’s slightly more pronounced with the S100. I had to dial down the mids quite a bit to get rid of the tinny nature of small speakers and wasn’t ever really able to get much punch on the low end. But, again, this isn’t an audiophile-grade speaker.\

After listening to a good amount of music through the S100, here are my conclusions:
- Alt-rock (such as Mazzy Star) is one of the better-sounding genres with this speaker. Of course, hearing Hope Sandoval through just about anything is a delight.
- Metal – the low end gets pretty muddy, but it can handle the genre without much distortion, no matter how loud you crank it. Although I will say that Devin Townsend’s new tunes really shine.
- Classical – with a fairly narrow soundstage, it’s hard to hear any separation of voices or instruments but the genre fared fairly well.
- Pop – even with the custom EQ, pop music did tend to sound a bit hollow and tinny.
- Classic rock – Van Halen sounded a bit crisper than other bands, which is primarily due to the mastering of their albums. AC/DC was respectable, and Kansas was clean, which led me to conclude that classic rock was every bit as good as alt-rock through the S100.
- Funk – The S100 really doesn’t have the bass to do funk justice, but apart from the low-end, it was certainly serviceable. I don’t know if this speaker would be George Clinton-approved, but what he doesn’t know won’t hurt him.
- 80s – music from the 80s sounds good through just about any speaker, so it’s almost unfair to include the genre. Even so, Saga’s “Worlds Apart” album really stood out for me (especially “The Interview” from “Worlds Apart”).
ZDNET’s buying advice
Anyone who doesn’t consider themselves audiophile-adjacent will appreciate the Tronsmart Mirtune S100
