Short answer: the Harman Kardon Luna 2. It ranks #25 of 177 medium speakers by sound quality, rated 4.1/5, at $199.95; the Sonos Play ranks #56, rated 3.5/5, and costs $299, which makes this an easy call rather than a real tradeoff.
The Harman Kardon Luna 2 is the better-sounding, lighter choice. A stylish waterproof speaker with clear, spacious mids, tight bass that stays clean at volume, and stereo pairing with a second unit. At 1.6 lbs (735 g) it weighs much less than the Sonos Play at 2.9 lbs (1.3 kg). It has an adjustable EQ, which the Sonos Play lacks. The catch: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The Sonos Play is the longer-running option. A Wi-Fi and Bluetooth portable with wide stereo sound, a long lasting swappable battery, waterproofing and full Sonos multiroom support. It is rated for 24 hours of battery against 12 for the Harman Kardon Luna 2. It keeps a wired aux input, which the Harman Kardon Luna 2 lacks. It plays in stereo from a single unit, unlike the Harman Kardon Luna 2. The tradeoff: Bass distorts noticeably on bass-heavy tracks at default settings, and the distortion persists even after enabling Trueplay tuning and manually pulling bass back in the app.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality than the Sonos Play and costs less, so only choose the other one for a particular feature it does better.
