Six axes, the same rule for every speaker. This is our judgment, not the manufacturer's.

Of the five speakers in this group, this is the one actually designed to be tied to a bike. The strap is silicone, it loops and buckles rather than clipping, and it closes around a handlebar or a frame tube the way a carabiner cannot. It is also the best-sounding of the five by a clear margin — that is what the money buys.
And its spec table says «Mounting Type: No Mount». The strap is in the product photos, it is in the second bullet point — «an improved utility strap mean you can attach the small Bluetooth speaker to a bag» — and it is the reason to choose this over a JBL. Amazon's field for exactly that says there is nothing there. Bose does the same thing on the SoundLink Flex listing further down this site.
Bose publishes no power figure at all. No watts, no RMS, nothing. On any other page that would be a complaint. Here, where JBL claims 180 W for a speaker the size of a fist and 4.8 W for the one next to it, an empty box starts to look like the only defensible answer.
Twelve hours, IP67, 330 g — the heaviest of the group, and you feel it on a bar. And like every other speaker on this site, no decibel figure anywhere.
Anything marked «—» is a figure the manufacturer doesn't publish. We don't fill those in by eye.

| «Mounting Type: No Mount» | The strap is the product. Bose's own second bullet: «an improved utility strap mean you can attach the small Bluetooth speaker to a bag». The spec table says there is no mount. It is the field this whole category turns on, and Bose fills it in wrong. |
|---|---|
| No power figure at all | Bose publishes no watts anywhere on the page — no maximum output, no RMS, nothing. Given that the JBLs on this site claim 180 W and 4.8 W for the same field, an empty box is arguably the honest answer. |
| «Number of Batteries: 1 AA batteries required» | A sealed rechargeable pack. The Bose SoundLink Flex listing says the same thing. |
| «Input Voltage: 240 volts» | It charges over USB-C, at 5 V. |
| The strap is silicone, not a carabiner | It loops and buckles rather than clipping, so it goes round a handlebar or a frame tube properly — better for a bike than a carabiner gate, and worse for hanging off a rucksack. |
| Mono, and it says so | «Number of Audio Channels: 1». One of the few places on this site where a listing admits a limitation instead of inventing a second channel. |
| $49 below list | $79.99 against $129.00. Bose discounts the Micro heavily and often. |
A summary of the reviews published on Amazon.com as of 2026-09-09.
4.6 out of 5 from 1,622 ratings on a young listing. The praise is almost entirely about sound out of proportion to the size, and about the strap. The complaints are the price and the weight, and a handful report the strap's buckle loosening over time.

Its Amazon page claims 180 watts and a 12-inch speaker, in a device 13 cm tall.
Its listing gives it a 12-inch subwoofer. The speaker is 9 cm across.
Ten dollars cheaper than the model it replaces, with a better water rating and an hour more battery.
