Real-Life Testing Story
"I took this speaker on a camping trip to the mountains. We were hit with unexpected rain, and everything was drenched. But the INSMY C12? It kept playing.
We stuck it on the side of a tent using the suction cup, and played music all night long. The battery lasted until the morning. The next day, I used the same speaker in the shower and was blown away by the sound."
And one more test:
"I attached it to my shower mirror, and even when water hit the speaker with full pressure — the sound didn’t distort at all. The bass stayed strong, and the clarity was just as good as in dry conditions."
For a budget speaker, this thing performs like a $50+ unit.
