Short answer: the Bose Soundlink Micro if sound quality matters most, the Monster Bluetooth Speaker if price matters most. The Bose Soundlink Micro ranks #20 of 62 small speakers, rated 3.5/5, at $99.99. The Monster Bluetooth Speaker ranks #39, rated 3.0/5, at $19.99, $80 cheaper.
The Bose Soundlink Micro is the better-sounding, deeper-bass choice. A rugged waterproof pocket speaker with a built in strap, party pairing, and low Bluetooth delay for video. Its bass reaches about 66Hz before falling 10dB, against 95Hz for the Monster Bluetooth Speaker. It links with other speakers (Bose Party mode), which the Monster Bluetooth Speaker cannot.
The Monster Bluetooth Speaker is the lighter pick. A very cheap, light waterproof travel speaker with USB-C charging, aux and microSD playback, and stereo pairing. At 0.4 lbs (185 g) it weighs noticeably less than the Bose Soundlink Micro at 0.6 lbs (289 g). It keeps a wired aux input, which the Bose Soundlink Micro lacks. It charges over USB-C rather than Micro USB. The tradeoff: Its tiny 36mm driver has very limited bass (about 95Hz at -10dB), elevated mids and rolled-off highs.
Buy the Bose Soundlink Micro when sound quality outweighs the price for you, and the Monster Bluetooth Speaker when the price outweighs sound quality instead.
