Short answer: the JBL Charge 6. At the same price, it ranks #12 of 172 medium portable speakers against the Luna 2’s #25, so the ranking should settle it.
The Luna 2’s strength is midrange precision. Its notes describe an articulate, spacious midrange with precise imaging and instrument separation, plus tight, well-controlled bass from its 62mm x 82mm woofer and passive radiator that the reviewer says stays cleaner at volume than pricier rivals like the Sonos Play. The tradeoffs are a treble that can sound bright and edgy, more output loss off-axis than some rivals, and occasional mid-range rattling some listeners hear on certain tracks. It also pairs two units into true stereo via AirTouch.
The Charge 6’s notes describe genuine tuning progress over the Charge 5. It seems more neutral with a flatter response through the mids and treble, since the Charge 5 was notably rolled off up high. It still isn’t neutral outright: the notes flag boosted bass by default, recessed mids, brightness above 2kHz, and an overall V-shaped response, though the reviewer points to a specific EQ correction that helps.
Battery life is not close. The Charge 6 is rated for 24 hours against the Luna 2’s 12, doubling it, and the Charge 6 also adds AAC codec support, an IP68 rating versus IP67, and Auracast party mode pairing that the Luna 2 lacks.
Buy the JBL Charge 6 for the higher rank, double the battery life, and broader feature set at the same price.
Buy the Harman Kardon Luna 2 if you specifically prefer its more articulate midrange and don’t mind the shorter battery life and single-unit mono sound.
