The Tribit MaxSound Plus Extra Bass Portable Speaker provides powerful sound from a small device. This Bluetooth speaker weighs less than a pound and a half, and it is fewer than eight inches long. Though it is petite in stature, it emits high-quality bass sounds so your music doesn’t suffer. This is the perfect speaker to take with you on adventures because it’s handheld and waterproof. And you won’t have to worry about the MaxSound Plus dying on you. Its rechargeable Lithium-ion battery will play music for 20 hours. So it’ll last for a day or two of full-time fun. Unlike some Bluetooth speakers, this one won’t tie you down. Its wireless range is 100 feet, so you can play beach volleyball while it hangs out by the BBQ.
