The Digitradio 231 OD does exactly that and shows what it's capable of, especially in nature during adventurous activities. Its robust construction and splash-proof housing (IPX4) can withstand a lot. The perfect outdoor companion. Beneath the tough exterior of the Digitradio 231 OD lies a wealth of entertainment potential. The device provides excellent radio entertainment via FM or in crystal-clear DAB+ quality. As a music fan with countless songs on your smartphone or tablet, you can also stream your favorite music wirelessly via Bluetooth through the radio's stereo speakers. Thanks to its power of 2 x 15 watts when plugged in and 2 x 8 watts when running on battery, it can drown out a lot of background noise. An integrated, powerful battery ensures up to eight hours of mobile music enjoyment. A special advantage for DIY enthusiasts: additional mounting plates are included for the optional use of existing 18V batteries from Bosch Professional, Makita, and DeWalt with the radio. This provides you with more flexibility, an increase in power to 2 x 15 W when using batteries, or even longer playtime.
