Short answer: the Harman Kardon Luna. It ranks #24 of 150 medium speakers by sound quality, rated 4.0/5, at $290.99. The Bose SoundLink Revolve (Series II) ranks #51, rated 3.6/5, at $194, $96.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Harman Kardon Luna: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. Watch for: Bass is limited by its 57Hz specification.
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. Watch for: RTINGS found it lacks low bass, so there’s little deep thump or rumble.
Buy the Harman Kardon Luna. It is rated higher for sound quality, and the $96.99 you would save on the Bose SoundLink Revolve (Series II) does not close the gap.

The Two Speakers In Full
Harman Kardon Luna: $290.99 Amazon eBay
Newer model: the Harman Kardon Luna 2, ranked higher, rated 4.1/5.
Pros: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. Its 1.13 kg, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. The sound is fairly balanced apart from the boosted bass. Measured bass extension of 57Hz (-10dB).
Cons: Bass is limited by its 57Hz specification. There is no companion app. No EQ adjustment. Boosted bass, and less detailed than higher-ranked speakers.

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.
