Party-Ready Audio

The comiso C15 Sky Blue speaker delivers 8W output through a single full-range driver with Bluetooth 5.3 connectivity. Its IPX7 rating allows full immersion at one metre for 30 minutes while a silicone shell resists dust and sand. Multi-colour LED modes sync to music for poolside or shower entertainment.

Build Integration

Wireless-only input means no cables to route and the 2000mAh battery powers extended sessions away from outlets. The 230g palm-sized body with integrated lanyard clips to packs, bikes or shower caddies. TWS pairing links two units for 360° stereo without extra hardware or app setup.

Upgrade Path

Replaces basic shower radios or clipped phone speakers that lack waterproofing or stereo separation. The jump is worthwhile when you need true immersion survival, floating retrieval and hands-free calling in wet environments. Not for buyers who want multi-room Wi-Fi audio or audiophile-grade fidelity.

Questions about this item

How long does the 2000mAh battery last at maximum 8W output?

Playtime depends on volume, LED patterns and audio content; the 2000mAh cell is rated for day-and-night use under typical conditions.

Does the speaker get hot or make fan noise during all-day playback?

The palm-sized 230 g design has no fan; heat stays low even during extended sessions at moderate volume.

What does the speaker need to pair with for stereo sound?

A second identical C15 unit is required — TWS mode links two speakers via Bluetooth 5.3 for 360° stereo.
