Short answer: the Klipsch Austin if sound quality matters most, the Monster Bluetooth Speaker if price matters most. The Klipsch Austin ranks #15 of 47 small speakers at $54.95. The Monster Bluetooth Speaker ranks #31 at $19.99, $34.96 cheaper.
What the Monster Bluetooth Speaker offers: A very light, IPX7-rated mini speaker with USB-C charging, aux and microSD playback, speakerphone support and TWS pairing. It is a convenient rugged travel speaker when water resistance and small size matter more than bass. Watch for: Its tiny 36mm driver has very limited bass (about 95Hz at -10dB), elevated mids and rolled-off highs. It cannot deliver the scale, detail or battery endurance of stronger small-speaker rivals, and no app or EQ is available to improve the tuning.
What the Klipsch Austin offers: Dual passive radiators give more low-end presence than most mini speakers. Clear mids and crisp trebles. Rugged rubberized build with a metal grille; IP67. Supports TWS pairing with a second Austin. Watch for: Not as deep bass as higher ranked speakers
Buy the Monster Bluetooth Speaker if the price is the priority over sound quality, or the Klipsch Austin if sound quality is the priority over the price.
