Older model: the Harman Kardon Go + Play 2 (ranked lower, rated 3.9/5). See every Harman Kardon Go + Play generation.

Pros: Warm sound with boosted bass. Deepest bass out of any speaker in this size. Sound is more natural than the Harman Kardon Go + Play 2. An aux input, a built-in microphone, a power bank function, stereo pairing and hidden button combinations for adjusting bass and treble. Measured bass extension of 35Hz (-10dB).

Cons: Just a little over half as loud as the higher rated boomboxes. Only 8 hours of battery at medium volume. No water rating.

Setup: Use the hidden EQ modes to adjust the bass up when outside and down when inside. To adjust bass, quickly press the bluetooth and volume down buttons together, the number of light flashes tell you what mode you’re in. To adjust treble, quickly press the volume up and phone buttons at the same time, the number of yellow flashes on the light tell you what mode you are in.
