Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Brane X ranks #4 of 117 large speakers by sound quality at $549; the Denon Home 150 ranks #6 of 15 powered desktop speakers by sound quality at $249.
The Brane X is the battery-powered, tougher option. A portable speaker with extraordinarily deep bass for its size, plus Wi-Fi, AirPlay, Alexa and a low latency aux input. Its battery is rated for 12 hours, while the Denon Home 150 needs an outlet. It is rated IP57, while the Denon Home 150 has no water resistance. It supports aptX HD Bluetooth, which the Denon Home 150 lacks. The tradeoff: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
The case for the Denon Home 150: A compact smart speaker with built in Alexa, easy HEOS setup and stereo pairing with a second unit. The tradeoff: Tom’s Guide’s own complaints are that it costs more than the Sonos One and has no automatic room tuning to correct for placement.
One note: the Denon Home 150 is no longer sold new, but at #6 of 15 powered desktop speakers by sound quality it still outranks most current models, so used is worth considering. The Denon Home 150’s replacement, the Denon Home 200, is still sold new.
Buy the Brane X at $549 if you want a large speaker. Buy the Denon Home 150 at $249 if you want a powered desktop speaker instead.
