JBL Go 3 vs Monster Bluetooth Speaker

What the JBL Go 3 offers: Genuinely pocket-sized at 209g. IP67 rated, survives full submersion in a meter of water for 30 minutes. Rope loop for clipping to a bag. Watch for: Not much bass at all, strange mids peak.

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.

Buy the JBL Go 3 if sound quality is the priority over the price, or the Monster Bluetooth Speaker if the price is the priority over sound quality.
