These days, there's no shortage of Alexa-enabled speakers, so companies have to differentiate through design and audio quality. One brand swimming in both is Libratone, which announced a new version of its Zipp and Zipp Mini speakers during IFA 2018. They offer up to 12 hours of battery life and connect over Bluetooth and WiFi -- including Spotify Connect and AirPlay 2 -- USB, and a 3.5mm mini-jack. Both ship with six microphones and, for the first time, support for Amazon's assistant, meaning you can request tunes and pizzas with your voice. Otherwise, you can control the speaker through the touchpad or companion mobile app.
