Bose SoundLink Micro (2nd Gen) Review: The Unkillable Pocket Speaker
1. Introduction: Physics vs. Portability
Small speakers usually sound terrible. It is a simple rule of audio physics: to make bass, you need to move air, and to move air, you need space. Most “micro” speakers end up sounding tinny, distorted, and weak.
The Bose SoundLink Micro (2nd Gen) attempts to cheat physics. By using a custom transducer and dual passive radiators, it squeezes surprisingly deep sound out of a silicone brick that fits in your pocket. But the real selling point isn’t just the sound—it’s the durability. This speaker is designed to be dropped, drowned, and dragged through the mud.
With 12 hours of battery life and a tear-resistant strap, is this the ultimate hiking companion, or are you just paying for the Bose logo? In this review, we analyze the durability, sound quality, and real-world utility of this rugged micro-speaker.
2. Key Features Explained Simply
Bose focuses on engineering over flashing lights. Here is what the tech inside this small box actually does.
Custom Transducer & Passive Radiators
The Benefit: This is how it makes bass. The main driver pushes sound out, while two passive radiators (wobbly rubber panels) vibrate in response to the internal air pressure. This amplifies the low-end frequencies without needing a massive woofer. It means you can actually hear the bass line in a song, not just the vocals.
IP67 Waterproof & Dustproof Rating
The Benefit: The ‘6’ means it is dust-tight (sand won’t get inside at the beach). The ‘7’ means it can be submerged in 1 meter of water for 30 minutes. If you drop this in a pool, a river, or a bathtub, it will survive. The silicone exterior also dries quickly.
Tear-Resistant Utility Strap
The Benefit: Most portable speakers have a flimsy loop for a carabiner. The SoundLink Micro has a thick, stretchy silicone strap that locks onto the back of the speaker. You can strap it tightly to a bike handlebar, a backpack strap, or a shower rod. It doesn’t dangle; it stays put.
SimpleSync Technology
The Benefit: If you own other Bose smart speakers or soundbars, you can group them. You can have the same music playing in your living room and on your patio simultaneously. You can also pair two SoundLink Micros for “Stereo Mode” (left/right separation) or “Party Mode” (double volume).
3. Hands-On Use & Performance
We took the SoundLink Micro hiking and tested it in a shower to see if it lives up to the “rugged” claim.
Sound Quality
For its size, the volume is impressive. It gets loud enough to fill a small room or a campsite. The sound signature is classic Bose: warm, with a boosted lower-midrange that makes voices sound rich.
The Limitation: Physics still wins eventually. At maximum volume, the bass thins out to prevent distortion (DSP limiting). It sounds best at 50-70% volume.
Durability Test
The silicone skin feels incredible—soft but grippy. It acts as a shock absorber. We dropped it onto hardwood from waist height, and it simply bounced. The IP67 rating held up; after a dunk in water, the audio was muffled for a few seconds until the water drained out, then it returned to normal.
Battery Life
Bose claims 12 hours. In our testing at 60% volume, we got around 10-11 hours. This is a solid improvement over the 1st Gen model (which only had 6 hours). It charges via USB-C, which is convenient since you can use your phone charger.
Microphone & Assistants
The built-in mic is surprisingly good. You can take calls on it, and people can hear you clearly even if the speaker is a few feet away. It also accesses Siri or Google Assistant with a button press.
4. Pros and Cons Table
| ✅ The Pros | ❌ The Cons |
|---|---|
| Size-to-Sound Ratio: Surprisingly full sound for something the size of a coaster. | No Aux Input: Bluetooth only; you cannot plug in an old iPod or device. |
| The Strap: The best mounting system on any portable speaker, hands down. | Mono Sound: It is a single driver speaker (unless you pair two). |
| Indestructible Feel: IP67 + Silicone wrap makes it worry-free. | Price: You pay a “Bose Tax”; cheaper options exist. |
| Speakerphone: High-quality mic for calls is a rare feature on micro speakers. | Bass Limit: Cannot reproduce sub-bass; hip-hop might sound thin. |

6. Who Should Buy This?
The Bose SoundLink Micro is a specific tool for specific users:
- The Cyclist: The strap locks perfectly onto handlebars. It is safer than wearing headphones because you can still hear traffic.
- The Hiker/Camper: It is light, rugged, and the battery lasts a full weekend of intermittent use.
- The Shower Singer: The IP67 rating and strap make it the ultimate shower speaker. It won’t die if it gets soaked.
Who should skip it? If you want room-filling sound for a house party, this is too small. Get the Bose SoundLink Flex or JBL Flip 6. If you don’t need a microphone, the JBL Clip 4 saves you money.
7. Comparison Summary
The JBL Clip 4 is great if you just want to clip it to a bag, but it lacks a microphone (no calls) and creates vibrations if you set it on a table.
The Tribit StormBox Micro 2 is the value king—it sounds great and can charge your phone—but the Bose strap is easier to use, and the Bose build quality feels slightly more premium.
The Bose SoundLink Micro wins on versatility. The strap allows it to attach to anything (poles, bars, straps), not just loops like the JBL clip.
8. Final Verdict
The Bose SoundLink Micro (2nd Gen) is the Swiss Army Knife of portable speakers. It isn’t the loudest, but it is the most useful.
The clever strap design, combined with the rugged build and surprisingly rich sound, makes it a device you will find yourself using constantly—in the shower, on the bike, or in the backyard. It justifies the “Bose Tax” by being incredibly well-engineered for real life.
Rating: 4.7/5 stars for Portability and Utility.
