Short answer: the Bose SoundLink Revolve (Series II). It ranks #51 of 150 medium speakers by sound quality, rated 3.6/5, at $194. The Marshall Emberton III ranks #110, rated 2.7/5, at $160.99, $33.01 cheaper, which does not close the gap in sound quality.
Why pick the Bose SoundLink Revolve (Series II): RTINGS measured a fairly neutral sound with a balanced midrange, so vocals and lead instruments come through clearly, and excellent directivity from the 360° design for an open, even sound around the room. The catch: RTINGS found it lacks low bass, so there’s little deep thump or rumble.
Why pick the Marshall Emberton III: 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. The tradeoff: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Bose SoundLink Revolve (Series II). It is rated higher for sound quality, and the $33.01 you would save on the Marshall Emberton III does not close the gap.
If battery life is a priority, the Marshall Emberton III is rated for 32 hours versus 13 hours for the Bose SoundLink Revolve (Series II).

The Two Speakers In Full
Bose SoundLink Revolve (Series II): $194.00 Amazon eBay
Older model: the Bose Soundlink Revolve (ranked lower, rated 3.5/5).
Pros: RTINGS measured a fairly neutral sound with a balanced midrange, so vocals and lead instruments come through clearly, and excellent directivity from the 360° design for an open, even sound around the room. In a side by side test against the Revolve+ II and B&O Beosound A1 2nd gen, several listeners preferred its clearer, less bass heavy tuning to the Revolve+ II. Up to 13 hours of battery, IP55 dust and water resistance, a built-in microphone for calls and voice assistants, and multi-connect for two devices at once.
Cons: RTINGS found it lacks low bass, so there’s little deep thump or rumble. It doesn’t get loud either: DXOMARK measured only about 73 to 74 dBA at maximum volume, against 85 to 89 dBA for speakers like the Sony SRS-XB43 in the same test, and bass compresses and pumps as you turn it up. There is no EQ in the Bose Connect app, a single unit plays mono, and it still charges over micro USB.

Marshall Emberton III: $160.99 Amazon eBay
Older model: the Marshall Emberton II (ranked lower, rated 2.7/5).
Pros: 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. IP67 rated, durable rubbery build using 50% recycled plastic. Measured bass extension of 62Hz (-10dB).
Cons: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud. Not really any different from the Emberton II except having the treble turned down a little bit.
