These are not really the same size class, and that is the honest framing here. The Harman Kardon Luna 2 ranks #25 of 179 medium speakers by sound quality at $199.95; the Sonos Move 2 ranks #28 of 120 large speakers by sound quality at $480.
The Harman Kardon Luna 2 is the lighter pick. 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 Move 2 at 6.6 lbs (3 kg). It has an adjustable EQ, which the Sonos Move 2 lacks. The tradeoff: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The Sonos Move 2 is the longer-running choice. A Wi-Fi and Bluetooth portable with warm, full sound, clear mids and a long battery for moving around the home. 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 catch: Not very loud.
Buy the Harman Kardon Luna 2 ($199.95) for a medium speaker; the Sonos Move 2 ($480) suits a large speaker instead.
