Harman/Kardon Go + Play 3 vs Harman/Kardon Onyx Studio 9

The Harman/Kardon Go + Play 3 is about double the size of the Harman/Kardon Onyx Studio 9, so it's probably unsurprising that it gets a lot louder and has a more consistent bass response. Both of these speakers have sleek yet understated designs that should suit most rooms in your home; their lack of IP ratings means you won't want to take them outside, anyway. They also both have a similarly balanced frequency response that suits a wide variety of audio, from podcasts to music. But if you like to tweak your speaker's sound, you'll want the Studio 9 as it comes with a companion app with a 7-band EQ.
