The Sound Tower MX-ST45B battery lasts up to 12 hours on a single charge, but when it's battery-powered rather than plugged into an energy source, the speaker's energy output is limited to 80W RMS as opposed to 160W. Multi-connection Bluetooth is a neat party trick, and so are the embedded LED lights that match the music's tempo. And if you're brave enough, you can sync up to 10 Sound Towers for a super loud party.
Samsung's new portable speaker is great for the outdoors
Speaking of parties, the Sound Tower MX-ST45B also has an IPX5 water resistance rating. In theory, this should protect it against low-pressure jets of water. In practice, the IPX5 rating should provide resistance against accidental spills and rainy weather. After all, it's a portable speaker with up to 12 hours of battery life on a single charge, and for good reasons, Samsung believes that people may want to use it indoors and outdoors.
As far as portability goes, the Sound Tower MX-ST45B measures 281.0 x 562.0 x 256.0 mm and weighs 8 kg. It has a 3.5mm input and ships with a remote but lacks optical input and NFC connectivity. The speaker also supports USB music playback and AAC, WAV, FLAC, and MP3 formats.
For the time being, the Sound Tower MX-ST45B seems to be available at Samsung's online shop only in Brazil for R$2,999 ($579). It could soon arrive in more markets. Brazilian customers buying the Sound Touwer before March 15 get a 6-month Spotify premium subscription for free.
