Let me tell you, this little speaker has completely transformed my shower routine. As someone who used to struggle to hear my phone's tinny speakers over running water, the C15's powerful 8W output is a revelation. I can actually hear every lyric now - no more awkward mumbling through songs I supposedly know!

The waterproof claim isn't just marketing fluff either. I've accidentally dropped it fully submerged multiple times (oops), and it keeps rocking like nothing happened. The soft-touch material feels premium in hand and that silicone lanyard? Genius for hanging it right under the shower stream.

What surprised me most was the battery life. After charging it once when it arrived, I've used it daily for showers and occasional poolside hangs for nearly six weeks before needing to recharge. The colored lights add such a fun vibe - I keep them on for morning showers to wake up, but appreciate being able to turn them off at night.

For kayaking trips, this has been perfect. It floats (!) and projects sound clearly over water noises and conversation. While the range isn't massive (about 20ft from my phone), that's never been an issue in practice. The TWS pairing works seamlessly when I want stereo sound by my pool.

Pro tip I discovered: holding volume buttons skips tracks! Small touches like this show thoughtful design. My only minor gripe? The lights reset to default each time rather than remembering my last setting.

At this price point, the sound quality punches way above its weight class. Crisp highs with satisfying bass that doesn't distort even at max volume in my tiled bathroom (sorry neighbors). If you want an affordable speaker that can handle real aquatic adventures while delivering great sound, this is absolutely it.
