Allow me to paint a picture.
Also: One of the most immersive speakers I’ve tested is not made by Sonos or JBL (and it’s on sale)
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 before 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.
Also: This Sony Bluetooth speaker sounds incredible for its price
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.

My experience
As I mentioned earlier, the Tronsmart Mirtune S100 speaker is loud. At the same time, it really does need the Tronsmart app to get the best sound. Out of the box, the sound is fairly hollow, with muddy lows and dull highs. Once I had the app connected to the speaker (which was surprisingly easy), I immediately went to the EQ tab and created a custom curve.
Unfortunately (as I’ve mentioned with other Tronsmart speakers), the EQ is limited to 5 bands, so you’re limited in how much you can adjust. Even so, with my usual curve (increased bass, lower mids, and increased highs), I was able to get some pretty decent sound from the S100.
Also: One of the most immersive soundbars I’ve tested is refreshingly compact (and $100 off right now)
I tend to be fairly forgiving of Bluetooth speakers because, by design, they cannot compete with the sound produced by wired speakers. And when a speaker sells for less than $100, you already know what you’re getting into.
That being said, with only a 5-band EQ at the ready and the decibels the S100 can produce, this baby is a steal.
You can plug in and charge your devices with the S100.

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.
Also: Finally, desktop speakers that look stylish without compromising on sound quality
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. However, 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 tended to sound 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<!–> Bluetooth speaker, even if only for the amount of sound it can produce.
It’s simple: if you don’t expect the high-resolution sound produced by far costlier speakers, the Tronsmart Mirtune S100 will serve you well. It’s rugged, easy to carry, has a built-in power bank (for when your phone gets low on juice), and is really, really loud.
If that sounds like the makings of a winner to you, then head over to the Tronsmart store (or Amazon), purchase a Mirtune S100 Bluetooth speaker, and crank up the noise and the funk.
