Daft punk song pops up when im at work. Only when i close i jam out at the end of the night. Bought a Polk Boom Swimmer at Sams Club and had an issue, messaged the manufacturer and they said to keep the old one amd sent me two brand new ones. They are Bluetooth speakers that can pain to have stereo sound or use alone, usually i use one with the tail attachment on my belt loop. They're pretty loud, high bass, waterproof, shock proof, and dirt resistant. Lasts 8 hours. (ps the video review on it the guy says it looks like a sperm with its tail)
