There’s nothing like a good demo to drive home a point. The representatives at Fugoo plunged their latest wireless Bluetooth speaker, the Fugoo XL, into a tank of water in front of me.

It was a demo at the 2015 International CES, the big tech trade show last week in Las Vegas. Fugoo says the wireless Bluetooth speaker is rugged enough to withstand mud, snow, water, and shock.

The Fugoo XL can play for 35 hours, compared to 10 or 12 hours for many other speakers. It uses 24 watts of audio power with four neodymium tweeters, two neodymium aluminum domed mid-woofers and two passive radiators. For audiophiles, that’s a lot of power. It has different jackets, including Style XL, Sport XL, and Tough XL. The Tough XL sells for $330, while the Style XL and Sport XL sell for $300.

The Fugoo XL and its accessories will be available in mid-April.
