Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Zealot S85 ranks #54 of 103 large speakers by sound quality; the Tronsmart Mirtune S100 ranks #95 of 166 medium speakers by sound quality at $79.99.
The case for the Zealot S85: 50W claimed (60W peak) from a 4 lbs (1.81 kg) cabinet measuring 25.7 x 10.5 x 15.5 cm, with a published 20Hz-20kHz response and separate tweeters plus bass woofers rather than one full-range driver. The catch: All performance figures are manufacturer claims: there are no independent frequency-response, SPL, distortion or impedance measurements, so real bass extension, maximum output and headroom are unknown.
The Tronsmart Mirtune S100 is the lighter option. Claimed 20 hours (manufacturer specified) battery life, ipx7 protection and limited-stereo playback make its feature set practical for its intended room or portable use. At 3 lbs (1.36 kg) it weighs noticeably less than the Zealot S85 at 4 lbs (1.81 kg).

The Two Speakers In Full
Zealot S85 Amazon eBay
Pros: 50W claimed (60W peak) from a 1.81 kg cabinet measuring 25.7 x 10.5 x 15.5 cm, with a published 20Hz-20kHz response and separate tweeters plus bass woofers rather than one full-range driver. The 8000mAh battery, Type-C charging, IPX6 sealing and anti-slip body suit camping, beach and workshop use. Three EQ modes, four inputs (Bluetooth 5.3, USB, TF card, 3.5mm line-in) and TWS pairing of two units for a claimed 100W cover solo listening and small parties, while rhythm-synced RGB lighting and a one-year warranty complete the package. Techder Audios calls it the clearer speaker against the Tronsmart Mirtune S100 and rates its bass and clarity highly for the price.
Cons: All performance figures are manufacturer claims: there are no independent frequency-response, SPL, distortion or impedance measurements, so real bass extension, maximum output and headroom are unknown. The 20Hz figure is implausible for a 1.8 kg passive portable, and driver sizes, charging time and Bluetooth codecs are undocumented. IPX6 resists water jets and rain but not immersion. No companion app, built-in call microphone or power-bank output is documented, and the 8000mAh is quoted at 3.7 V from a 7.4V/4000mAh pack, so real runtime is unverified. Reaction is not unanimous: one independent reviewer was sharply disappointed by the build and sound.

Same family: the Tronsmart Mirtune C3 (larger model, ranked lower, rated 3.1/5), the Tronsmart Mirtune C3 Plus (larger model, ranked higher, rated 3.3/5) and the Tronsmart Mirtune H1 (larger model, rated 3.4/5).
Pros: At 1.36 kg, Tronsmart Mirtune S100 combines 20W drivers with Bluetooth. Claimed 20 hours (manufacturer specified) battery life, ipx7 protection and limited-stereo playback make its feature set practical for its intended room or portable use. Measured bass extension of ~64Hz (-10dB).
Cons: Bass is limited by its ~64Hz specification. There is no companion app. No EQ adjustment.
