Jason Mraz's Must-Have Products: From a Humidifier to a Portable Speaker

"If you play music or wish to learn, I think investing in an instrument is a must for the home," Mraz says, and he recommends the Taylor Guitars Jason Mraz Signature Model (JMSM) ($3,499). "If you're a beginner, Taylor offers the wonderful Academy series, which are excellent starter guitars for a smaller investment. I prefer the Academy nylon."

Pro Tip: He also recommends the app Yousician to learn at home. "It'll show you the basics of strumming and where the chords are. They have different games that you can kind of play along to, and it knows if you're playing the right notes or not," he says.
