We were introduced to this speaker by a friend on our Lake Tahoe trip. Waterproof, drop-proof and all-in-all baby proof, this speaker will allow you to play baby-calming music all the while your baby attempts to eat, tear apart and destroy it. Compact and easy to store in the stroller, you will never be without music again.

Connects to your mobile device via Bluetooth. Karina's favorite songs are anything by Shakira, Romeo Santos and Gloria Estefan. As an aside her first word after mommy, daddy and mum mum was Gracias! Teaching your baby a second language starts with music selection!
