The Caston ST H20 is a portable Bluetooth speaker, a “super loud” speaker with big bass and multiple input modes (USB, AUX, memory/TF card). It’s aimed at users who want a relatively affordable speaker for home, outdoor or travel use—with emphasis on volume and bass punch rather than premium audiophile fidelity.
Visually, it features a compact rectangular shape (approx. 105 × 105 × 130 mm per one listing) and uses a combination of mesh fabric and rubberised surfaces, with a rubber loop/lanyard for portability.
It supports multiple playback modes (Bluetooth wireless, USB stick, microSD/TF card, Aux-in) and also appears to support TWS (True Wireless Stereo) interconnect (i.e., pairing two units) as per the description.
Power & Bass: The ST H20 is advertised with dual 15 W full-range speakers, dual 57 mm horns and dual 75 mm vibrating diaphragms (according to one listing) for “360° stereo & super audio”.
Battery & Portability: Has a 4,000 mAh battery pack (7.4 V) aimed to deliver up to 8 hours of playback at moderate volume. Charging via Type-C port, full charge in approx. 3.5 hours according to listing.
Multi-input flexibility: Supports Bluetooth wireless connectivity, USB input, TF (microSD) card slot, 3.5mm AUX input—so you’re not limited to just Bluetooth.
Design & build: Rubber fabric + plastic housing, rubber lanyard for carrying; weight ~770 g per listing.
“Super loud” marketing: The unit is clearly targeted at louder playback players (parties, gatherings) – the listing emphasises “high volume”, “big bass”.
