The Ontanma Speaker is the ideal speaker for everyone who likes to sing in the shower. The speaker is essentially a waterproof enclosure with a 3.5mm jack for your smartphone or MP3 player. The Ontanma Speaker's droplet-like design allows it to be hung from your shower rack or shower head.
The Ontanma Speaker comes in a ton of colors so finding one that suits you shouldn't be too tough. There are many waterproof smartphone cases on the market today, but these cases are designed simply to let you use your phone in wet areas, not to amplify the sound that comes out of it. The Ontanma Speaker is available from Rakuten's website and sells for $13.
