#36 Monster Bluetooth Speaker: $19.99 Amazon eBay

Pros: 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. Measured bass extension of 95Hz (-10dB).

Cons: 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.

How it compares: Just above it: Dayton Audio Boost Mini. Just below it: Boat Stone 190 - $1 cheaper.
