Portable Bluetooth speakers are a great way to bring the party anywhere, but they often forgo sound quality for portability. That’s not the case with the Bose SoundLink Micro. Even a few years after its release, this waterproof speaker remains one of our favorites. It even has an elastic strap that can loop around your bike or bag during an outdoor adventure day.

Editor’s note: this review was updated on April 2, 2021, to include a microphone demo and poll and add technical information.

Who should get the SoundLink Micro?

The Micro can easily hook onto a backpack and project sound during a hike or just stay there during a commute.

  • Hikers can latch this speaker to a backpack strap. It’s just asking for your to take it on your next big adventure, and the IPX7 rating means you can take it out in the rain.
  • Bikers can secure the speaker around their handlebars and play music while biking. This is preferred to using earbuds while commuting because you can stay aware of all that’s going on around you.
  • Students who need a reliable Bluetooth speaker should get the SoundLink Micro. From dorm parties to apartment parties, there’s bound to be a time and a place that needs music. Despite its size, the Micro actually gets quite loud and can fill a college dorm room with sound.

What is it like to use the Bose SoundLink Micro?

You can submerge the SoundLink Micro for up to 30 minutes.

The SoundLink Micro is available in black, midnight blue, and orange. A soft-touch rubberized finish, identical to the Bose SoundLink Color II, makes it easy to grip while protecting it from the environment. Although the SoundLink Micro is resistant to water, it can’t float like the UE Roll 2. Still, it makes for a great shower speaker.

For the curious, the speaker continues to play music while submerged. Just for kicks, I tried to use Google Assistant while it was submerged and couldn’t get it to work. When out of the water, the Micro’s microphone effectively registers voices for smart assistant requests and phone calls.

This durable speaker also includes a tear-resistant silicone strap. Try as you may, that strap knows resilience. It’s easy to latch this onto a backpack, bike rack, or anything else you can wrap it around. The latch secures into a cutout built into the back of the speaker, which keeps things nice and tidy.

How do you connect the Bose SoundLink Micro?

The SoundLink Micro only supports the SBC Bluetooth codec, but it has a premium feature too: Bluetooth multipoint. You can connect it to two source devices at once. This nifty feature lets you stream music from your computer while keeping an ear on notifications from your smartphone.

Audio lags behind video with a one-second delay. The same goes for commands, like skipping tracks. This isn’t a deal-breaker but can be annoying at times, especially when you don’t know if it’s just a latency issue or if Google Assistant didn’t hear you.

What does the Bose Connect app do?

Bose SoundLink Micro and Bose Connect app.

The Bose Connect app supports stereo playback.

The Bose Connect app offers fun features like Party Mode, which lets you connect two SoundLink speakers for double the audio output. You can even use Party Mode to listen in stereo, so long as you place the speakers far enough apart. You also get other features from the Bose Connect app like an auto-off timer, virtual volume controls, and more. While all of these things are nice to have, the main reason you should get the Bose Connect app is for access to firmware updates.

How’s the battery life?

Charging the SoundLink Micro takes anywhere from 3-4 hours via micro-USB.

The Bose SoundLink Micro’s battery life falls short of the 6-hour playtime. When we set the volume to 50%, we squeezed out around 5 hours of playtime.

According to Bose, a 1A power source will take 4 hours to complete a full charge cycle while a 1.5A source will take closer to 3 hours. That ratio of charge time to playback time—not great. On the flip side, users can simultaneously play music while charging if at home or using a portable power pack.

Should you buy this over the Bose SoundLink Micro or the SoundLink Color II?

Dual-opposing, passive radiators are housed inside the Bose SoundLink Color II speaker. This minimizes surface vibrations while maximizing volume output.

There are plenty of reasons to go with this micro speaker over the larger alternative. The SoundLink Micro is less than half the size of the Color II and half the weight. If travel is your main concern, the SoundLink Micro is the better pick. Not only does it take up less space, but it can also be hooked onto almost anything.

The Bose-branded SoundLink Micro and Color II share many of the same features: both can connect to an Amazon Echo Dot and both support virtual assistants like Google Assistant. Both support Bluetooth multipoint connectivity, allowing for each speaker to simultaneously connect to two devices via Bluetooth multipoint. The main difference, regarding features, is that the SoundLink Color II includes a 3.5mm input.

If you want better, louder audio playback, get the SoundLink Color II.

Does the Bose SoundLink Micro sound good?

The Bose SoundLink Micro is a great companion for small outdoor gatherings from grill to the table.

This speaker gets plenty loud. Volume output rivals the larger SoundLink Color II but can’t quite match it. Still, users won’t away with blasting the volume from a modestly sized apartment complex. As a matter of fact, the most defining aspect of this speaker may very well be its volume. Though it won’t be able to entertain a large party, the Micro can certainly handle intimate gatherings.

Lows, mids, and highs

Its minuscule size is misleading since the SoundLink Micro is able to pump out unexpectedly strong bass. With volume maxed out while playing Stupid Rose by Kweku Collins, my hand felt was 10cm away and felt air movement from the speaker’s dynamic driver.

The Bose SoundLink Micro can easily fill a dorm room or medium-sized living space with music.

Collins’ vocals are reproduced clearly and aren’t masked by the low-end until the volume reaches 75%. Again, bumping the volume beyond 60% diminishes sound quality. In Stupid Rose, treble clarity drops off during the synth-solo that begins at 2:45. With a speaker like the Micro, volume likely takes precedence over clarity allowing for difficult-to-differentiate notes to be forgiven.

Does the Bose SoundLink Micro have a microphone?

The Bose SoundLink Micro is a rare breed of Bluetooth speaker that includes an integrated microphone system, which is great but it doesn’t sound spectacular. Low and midrange vocal frequencies are attenuated which can make you sound a bit unnatural. Plus, there seems to be some static that’s relayed during phone calls. Take a listen to and rate the demo below, doing so really helps other readers understand how the mic compares to a wide variety of products.

If you’re big on traveling and want a speaker that you can take anywhere, the Bose SoundLink Micro is the Bluetooth speaker for you. Alternatively, you can save some dough and go with the JBL Clip 3 for less. If you want to spring a bit more cash while still staying under the $100-mark, get the UE WONDERBOOM 2. The main benefit here is that the WONDERBOOM 2 floats and it emits 360° sound.

For those on the fence, know this: you won’t be disappointed by the SoundLink Micro. This is one of the best compact, durable, portable speakers around.
