Having already mastered the development of big, Bluetooth party speakers with flashing lights and gesture-activated sound effects, Sony has taken on a new challenge for what’s probably its weirdest gadget at CES 2019: it’s trying to build the ultimate tailgating speaker; the ultimate barbecue speaker; the ultimate outdoor speaker. This is the GTK-PG10, and if we are to properly recognize its greatness, step one is ignoring that product “name.”

This $250 speaker has a dedicated outdoor party mode. What does it do? How does it change the music EQ? Sony says that the DSP (digital signal processor) “automatically adapts audio settings to optimize outdoor performance.” Its rechargeable battery is good for up to 13 hours of playback.
