Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Brane X ranks #4 of 78 large speakers by sound quality at $500; the Denon Home 350 ranks #6 of 6 powered desktop speakers by sound quality at $749.
The case for the Brane X: The Brane X pairs a dedicated RAD subwoofer with two midrange drivers and two tweeters to achieve extraordinary low bass for a 3.5kg portable: its measured -10dB extension is 31Hz. 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 350: RTINGS measured it getting pretty loud with lossless streaming support from platforms like Roon, Tidal and Spotify, and found its Alexa voice assistant support outstanding, with hands-free far-field mics built directly into the speaker. The tradeoff: 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 ($500) for a large speaker; the Denon Home 350 ($749) suits a powered desktop speaker instead.
If water resistance matters to you, the Brane X at IP57 (brief submersion) holds up far better than the Denon Home 350 at no water resistance.

The Two Speakers In Full
Brane X: $500 Amazon eBay
Pros: The Brane X pairs a dedicated RAD subwoofer with two midrange drivers and two tweeters to achieve extraordinary low bass for a 3.5kg portable: its measured -10dB extension is 31Hz. Independent testing finds it loud, with well-balanced mids, a smooth treble balance and useful bass-level controls; Wi-Fi, AirPlay, Alexa, quality Bluetooth codecs and low-latency aux pass-through make it unusually versatile. Measured bass extension of 31Hz (-10dB).
Cons: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it. Bass response shifts at maximum volume, the default aux mode has very high latency, and some listeners find the upper register edgy or need EQ to achieve their preferred balance. Its claimed 12-hour runtime and premium cost make it more of a compact high-end system than a carefree all-day speaker.

Denon Home 350: $749 each Amazon eBay
Pros: RTINGS measured it getting pretty loud with lossless streaming support from platforms like Roon, Tidal and Spotify, and found its Alexa voice assistant support outstanding, with hands-free far-field mics built directly into the speaker. Two 0.75-inch tweeters, two 2-inch midrange drivers and two 6.5-inch woofers are each driven by their own Class D amp, six in total, and the companion app adds bass and treble sliders for room-to-room tuning.
Cons: 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. Bluetooth latency measured extremely high on both iOS and Android, making it a poor match for watching video over Bluetooth, and there’s no battery, so it’s an indoor, mains-powered speaker only.
