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 350 ranks #9 of 10 powered desktop speakers by sound quality at $749.
The Brane X is the battery-powered, tougher pick. 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 350 needs an outlet. It is rated IP57, while the Denon Home 350 has no water resistance. It supports aptX HD Bluetooth, which the Denon Home 350 lacks. The catch: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
What the Denon Home 350 does well: A large Wi-Fi smart speaker that plays loud, with lossless streaming, built in Alexa that hears you well, and app tone controls. The catch: RTINGS measured a slightly boomy sound profile out of the box and disappointing directivity, so the sound changes noticeably off to the side of the cabinet, plus compression artifacts as it nears max volume.
Buy the Brane X ($549) for a large speaker; the Denon Home 350 ($749) suits a powered desktop speaker instead.
