These sit in different size classes, so this is not a straight ranking comparison. The CMF Speaker M ranks #87 of 176 medium speakers by sound quality at $89; the Bose Soundlink Micro 2 ranks #18 of 62 small speakers by sound quality at $129.
The CMF Speaker M is the longer-running choice. A two way design with a 70mm woofer and 16mm tweeter on 35W, giving crisp treble, detailed vocals, and a fairly neutral tuning on most music. It is rated for 18 hours of battery against 12 for the Bose Soundlink Micro 2. Watch for: Struggles with dense rock and metal at volume, where the low end gets muddy and vocals turn shrill even with Ultra Bass on.
The Bose Soundlink Micro 2 is the lighter 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 CMF Speaker M at 1.3 lbs (602 g). It supports aptX Bluetooth, which the CMF Speaker M lacks. The catch: Lack of clarity.
Buy the CMF Speaker M at $89 for a medium speaker, or the Bose Soundlink Micro 2 at $129 for a small speaker instead.
