Verdict: Buy the Bose SoundLink Micro 2nd Gen if you want a truly small speaker with a carry strap, USB-C, IP67 protection, and clearer sound than the original at ordinary listening levels. Skip it if you want speakerphone calls, long high-volume playback, stereo from one unit, or deep bass. At the $129 MSRP reported by SoundGuys, its appeal is how easily it straps to a bag or bike, not audio-per-dollar. If you already own the first Micro, the upgrade is optional; Erin Lawrence also says Gen 1 owners needn’t rush to replace theirs.
Bose removed the microphone. Erin Lawrence also confirms that the new model can’t take calls or activate a phone’s voice assistant. It plays in mono; SoundGuys says Bose’s stereo pairing needs a second Micro 2nd Gen, so there is no left-right separation from a single purchase.
How good does the Bose SoundLink Micro 2nd Gen sound for its size?
SoundGuys calls the second generation better sounding, while noting its stamina is limited. Erin Lawrence also hears clearer vocals and fuller bass than the original, but says the bass is not earth-shaking and describes the presentation as somewhat directional. Those are reviewer impressions, not measurements by ArmorSound. They point to the right expectation: this is a close-up personal or small-room speaker, not a pocket-sized replacement for a larger outdoor model.
The case is still very compact and Bose lists a removable fabric strap and IP67 protection, which adds dust protection to water resistance. Erin Lawrence describes the strap as replaceable. That rating is useful for a bag, trail, or wet kitchen counter; it does not mean the speaker floats, and you should check Bose’s product information for care instructions before exposing the USB-C port to water.
How long does the battery last at high volume?
Bose advertises up to 12 hours of playback. Treat that as a maximum, not a promise for loud use. SoundGuys says Bose’s manual gives roughly three hours at maximum volume; in the reviewer’s own test, its sample lasted about 4.5 hours at a stated 80 dB measured one metre away. Those different conditions are not directly comparable, but they agree on the practical point: a long day at high output is not this speaker’s strength. Erin Lawrence calls battery life average and says a full recharge took about three hours.
If your listening is mostly podcasts or music at moderate volume while walking, the rated 12 hours may be adequate. If you expect to play it loudly for an afternoon outdoors, carry a charger or choose a larger speaker. The strap helps you take it along; the battery figures do not make it a high-output all-day speaker.
What changed from the first generation?
The second generation adds USB-C, moves to IP67, and replaces the fixed rubber strap with a removable fabric one. SoundGuys identifies Bluetooth 5.4 and multipoint connections, and describes Bose’s basic three-band EQ. It also removes the old model’s microphone, so the new speaker loses its call and voice-assistant function. SoundGuys says stereo playback requires two second-generation Micros. Confirm exact app and pairing support in Bose’s current instructions before buying a second unit, especially if you’re trying to mix generations.
The 20 newest comments reviewed under SoundGuys’ video were anecdotal and mixed. They include a first-generation owner whose strap tore and a commenter who likes the second generation’s replaceable strap; another owner discussed listening beyond Bose’s rated runtime. This tiny, self-selected sample can’t establish typical durability or battery life, but it does make the removable strap a useful ownership detail: replacement is possible if the strap wears out.
Should you upgrade or buy one?
Choose the SoundLink Micro 2nd Gen when pocketable size, a secure strap, dust and water resistance, and modest-volume listening matter more than long runtime or calls. Keep the first-generation Micro if it still meets your needs and you use its microphone. If price matters more than Bose’s compact carry design, SoundGuys compares alternatives including the Tribit StormBox Micro 3 and Soundcore Boom Go 3i; compare their current prices and fit before choosing.
If you can carry a larger speaker and want a longer manufacturer-rated battery, our Beats Pill review explains its stronger fit for travel and its limits at high volume.
