Short answer: the Soundcore Motion 300. It ranks #3 of 179 medium speakers by sound quality, rated 4.5/5, at $79.99; the Bose Portable Smart Speaker ranks #75, rated 3.4/5, and costs $399, so there is not much of a tradeoff to weigh.
The Soundcore Motion 300 is the better-sounding, lighter option. A compact stereo speaker with deep bass for its size, hi res Bluetooth and a custom EQ for each position, standing or lying down. At 1.7 lbs (772 g) it weighs noticeably less than the Bose Portable Smart Speaker at 2.3 lbs (1.06 kg). It is rated IPX7 against IPX4 for the Bose Portable Smart Speaker. It supports LDAC Bluetooth, which the Bose Portable Smart Speaker lacks. Watch for: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings.
Why pick 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 Soundcore Motion 300. It is rated higher for sound quality than the Bose Portable Smart Speaker and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
