Sony SRS-XB30 vs Harman Kardon Esquire 2

Last updated: August 28, 2026

Short answer: the Sony SRS-XB30. It ranks #104 of 136 medium speakers by sound quality at $199; the Harman Kardon Esquire 2 ranks #120 and costs $200, so there is little reason to consider the other one.

What the Sony SRS-XB30 offers: IPX5 rated. Doubles as a power bank for charging your phone. Long claimed battery life (up to 24 hours at moderate volume). Watch for: Muffled sound, worse than a XB20

What the Harman Kardon Esquire 2 offers: Doubles as a conferencing speakerphone with a 4-mic array and noise/echo cancellation. Flat, compact design packs easily. USB charge-out for topping off a phone. Watch for: Bass is weak, vocal and instrument separation is underwhelming and sounds tinny at high volume

Buy the Sony SRS-XB30. It ranks higher for sound quality than the Harman Kardon Esquire 2 and costs less, which settles it without a real tradeoff to make.

Neither of these is a sound-quality pick. Look higher up the 136 medium speakers if that is what you are optimizing for.

There is a real battery-life gap here: the Sony SRS-XB30 is rated for 24 hours, the Harman Kardon Esquire 2 only 8 hours.
