What the Harman Kardon Go + Play 2 offers: Warm sound with boosted bass. Watch for: Not as loud as others. No water rating.
What the JBL Boombox offers: Connect+ up to 100 speakers. Watch for: Treble isn’t very smooth
Buy the Harman Kardon Go + Play 2. It ranks higher for sound quality than the JBL Boombox and costs less, so the other one has nothing left to offer.
There is a real battery-life gap here: the JBL Boombox is rated for 24 hours, the Harman Kardon Go + Play 2 only 8 hours.
There is a real gap in water resistance: the JBL Boombox at IPX5 (water jets) against the Harman Kardon Go + Play 2, which has no water resistance.
