Short answer: the Harman Kardon Luna 2. It ranks #23 of 150 medium speakers by sound quality, rated 4.1/5, at $199.95. The Bose SoundLink Revolve (Series II) ranks #51, rated 3.6/5, at $194, $5.95 cheaper, which does not close the gap in sound quality.
What the Harman Kardon Luna 2 does well: Articulate, spacious midrange with precise imaging and instrument separation. The catch: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The case for 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 tradeoff: RTINGS found it lacks low bass, so there’s little deep thump or rumble.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality, and the $5.95 you would save on the Bose SoundLink Revolve (Series II) does not close the gap.

The Two Speakers In Full
Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Older model: the Harman Kardon Luna (ranked lower, rated 4/5).
Pros: Articulate, spacious midrange with precise imaging and instrument separation. Tight, well-controlled bass from the 62mm x 82mm woofer and passive radiator despite the compact body, and it stays cleaner at volume than pricier rivals like the Sonos Play. IP67 rated, and two units pair via AirTouch for true stereo sound.
Cons: Treble can sound bright and edgy, and it loses more output off-axis than some rivals. Some listeners hear mid-range rattling on certain tracks, similar to sibling JBL models. 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it. Single unit is not stereo (1.1 driver layout).

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.
