Our Verdict

Denon Home 350

Harman/Kardon Onyx Studio 6

The Harman/Kardon Onyx Studio 6 and the Denon Home 350 have different strengths and depending on your usage, you may prefer one over the other.  The Harman/Kardon is a battery-powered speaker that you can take with you outdoors. It has an IPX7 rating for water resistance, although we don't currently test for this, its Bluetooth performance is better, and it can be paired with up to two devices at once. However, the Denon is a home speaker that can only be used wired. It has a more neutral sound profile out-of-the-box, a better soundstage and dynamics performance, and it supports Wi-Fi. It also has a companion app with bass and treble sliders so you can tweak its sound to your liking.
