A speaker may not seem like an essential device for college, but I can promise you it is. I remember the struggle of playing music with the smallest, cheapest speaker I could find on Amazon when I had people over during my freshman year of college. Looking back, I wish I'd just invested my money in a solid speaker that could fill the empty air in any room. Bose's dual portable speaker set can do just that. It includes two speakers that can be synced up when set into Party Mode on the Bose app, allowing the audio to play in perfect unison.
Though the sound won't be as high quality as what you'd get with larger, more expensive speakers, the set makes for a great addition to any dorm room pregame. Plus, the speakers are waterproof and have a 12-hour battery life, so you can blast music from just about anywhere.
