These sit in different size classes, so this is not a straight ranking comparison. The Bose Soundlink Micro 2 ranks #18 of 62 small speakers by sound quality at $129; the Bose Portable Smart Speaker ranks #75 of 179 medium speakers by sound quality at $399.
The Bose Soundlink Micro 2 is the lighter, tougher choice. A waterproof mini speaker with a fabric strap for bags and bikes and USB-C charging. At 0.7 lbs (329 g) it weighs much less than the Bose Portable Smart Speaker at 2.3 lbs (1.06 kg). It is rated IP67 against IPX4 for the Bose Portable Smart Speaker. It supports aptX Bluetooth, which the Bose Portable Smart Speaker lacks. Watch for: Lack of clarity.
The case for the Bose Portable Smart Speaker: A smart speaker with Alexa and Google Assistant built in that streams over Wi-Fi at home and Bluetooth on the go. The catch: RTINGS found the out of the box tuning boomy and says it doesn’t get very loud; the app’s bass and treble sliders help, and SoundGuys recommended cutting bass by 10 to 20 steps to balance it.
Buy the Bose Soundlink Micro 2 at $129 for a small speaker, or the Bose Portable Smart Speaker at $399 for a medium speaker instead.
