Short answer: the Harman Kardon Luna 2 if sound quality matters most, the Soundcore 3/Soundcore Select 2 if price matters most. The Harman Kardon Luna 2 ranks #23 of 142 medium speakers at $199.95. The Soundcore 3/Soundcore Select 2 ranks #57 at $49.99, $149.96 cheaper.
What the Harman Kardon Luna 2 offers: 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. Watch for: 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).
What the Soundcore 3/Soundcore Select 2 offers: Soundcore 3/Soundcore Select 2 uses 2x 38mm (1.5”) titanium diaphragm full-range drivers + 2x passive radiators. Its 372 g, claimed 24 hours (Manufacturer specified) battery life, IPX7 protection, up to 99dB and stereo playback make it a practical option for its intended room or portable use. Watch for: Bass is limited by its 60Hz specification.
