Introducing the KitSound Mini Buddies Adorable and portable, what the KS Mini Buddy speakers lack in size, they make up for in volume. Big Sound 'Less is more'; 'Don't judge a book by its cover'; 'Good things come in small packages'. There are many sayings we could use to describe the KS Mini Buddies, but for the sake of simplicity we'll just say they're surprisingly loud. Bigger sound On its own a Mini Buddy sounds impressive, but if you want even more volume, you can connect two or more of them together for increased impact. And with the Mini Buddies coming in a variety of cute designs, it's a good excuse to collect the whole family. Ultra portable Just because a Mini Buddy boasts big sound, it doesn't mean the speaker itself has to be big. Measuring around 50 mm wide, 55 mm high and 48 mm across, they're ultra-portable and even come with a key ring attachment, so you can hear your music out loud wherever you are. Easy to Use Simple to use, you just plug it into your mobile, tablet, PC or music device using the 3.5 mm headphone jack and turn it on. Charging the built-in Li-ion battery can be done by simply plugging the supplied USB cable into a PC, laptop, USB mains charger or USB car charger. About KitSound We are craftspeople.
