The Bang & Olufsen Beolit 20 is a beautiful Bluetooth speaker with a noticeable upgrade from the Beolit 17. One of the most notable upgrades is the built-in Qi-wireless charging shelf on top of the speaker. You can listen to your favorite music while charging your smartphone at the same time. Also, with a bigger battery, you can get up to 8 hours of playtime on a single charge using normal listening volumes. You can connect different devices wirelessly through Bluetooth, and you can also create a stereo sound by connecting an additional Beolit 20 or Beolit 17 for a richer sound. The Beolit 20 is composed of an aluminum and rubber exterior, comes with a convenient carrying strap, and comes in two colors: Grey Mist and Black Anthracite. You will defiantly enjoy a satisfying range of bass and a better acoustic experience due to its powerful drivers and amplifiers.
