9 JBL Flip 4
Speaking of Bluetooth speakers that work with your Echo Dot, it pays to buy one that has some versatility. The JBL Flip 4 packs some serious, 360-degree audio quality — including no shortage of bass — into a portable form factor. It’s plenty loud enough for dorm rooms, but you can also take it with you for house parties or wherever else you might want to jam out to your favorite music. And don’t worry about getting it wet in the rain or at a pool party — it’s waterproof.
