We love our iPhones, but we have to be honest: their speakers are pretty weak. The Amp iPhone Speaker Case aims to fix that, and in a big way. Instead of just boosting the sound coming out, the Amp uses advanced algorithms to deliver personalized audio, based on your hearing pattern, musical preferences, and your surrounding environment. Features include an ARM M4 processor, 24-bit digital-to-analog converter, and a built-in battery that provides up to 7 hours of playback through the powerful 14x20 mm drivers or 20 hours of playback through the built-in headphone amplifier, while also boosting your battery life by over 25%. Available for the iPhone 5, 5S, 6, and 6 Plus.
At nearly a foot long and over four inches tall/deep, the Tivoli Music System Three isn't going to replace the smallest of portable speakers — but it also offers far better sound. Boasting two custom 3-inch speakers with dual bass ports, it delivers rich, full audio, while offering excellent portability thanks to an integrated handle that houses a remote and a 20-hour rechargeable battery. It features Bluetooth for wireless streaming, but should you decide to kick it old school, it also features a sensitive AM/FM RDS tuner that works even after your phone's died — which is more than we can say for that tiny speaker you've been carrying in your bag.
