Six axes, the same rule for every speaker. This is our judgment, not the manufacturer's.
| Battery life | 6/10 | |
|---|---|---|
| Sound | 9/10 | |
| Potencia | 6/10 | |
| Portability | 6/10 | |
| Durability | 8/10 | |
| Value | 5/10 |
This is the one that sounds best. Bose's tuning at this size is not matched by anything else on the page, and $119.99 is what that costs. It is also the only product on this site with a published spare-parts commitment — seven years — which for something you will drop on gravel is worth more than most spec rows.
Then there is «Specific Uses For Product: [INF]». A placeholder token, sitting in a customer-facing field on a $120 product page. Somewhere upstream a pipeline wrote the string «[INF]» and nobody has looked since.
«Mounting Type: No Mount», while the third bullet on the same page says you can «clip onto a bag using the utility loop». Bose does this twice on this site — the SoundLink Micro's strap gets the same treatment. It is the field that decides whether a speaker can travel on the outside of a bag, and Bose gets it wrong on both of their products.
And the power figure: 7.5 watts. The $24.99 BolaButty above claims 20 W. The $59.99 JBL Clip 5 claims 180 W. This one, the most expensive and by some distance the loudest-sounding, claims 7.5. Three products, three numbers, no relationship to price, size or volume. If you take one thing from this category, take this: the watt column on Amazon means nothing, and the number that would mean something — maximum volume in decibels — is not published by a single one of the ten speakers here.
Anything marked «—» is a figure the manufacturer doesn't publish. We don't fill those in by eye.

| «Mounting Type: No Mount», and there is a loop | Bose's third bullet: «small enough to fit in your hand or clip onto a bag using the utility loop». The spec table says there is no mount. Bose fills the same field in the same wrong way on the SoundLink Micro listing on this site. |
|---|---|
| «Speaker Maximum Output Power: 7.5 watts» | For a $119.99 speaker. The $24.99 no-name on this page claims 20 W and the $59.99 JBL Clip 5 claims 180 W. Three speakers, three numbers, no relationship to either price or loudness. This is the field to ignore. |
| «Specific Uses For Product: [INF]» | A placeholder token, published. Somebody's data pipeline wrote «[INF]» into a customer-facing field and nobody looked. |
| «Number of Batteries: 1 AA batteries required» | Sealed lithium pack, as on the Micro. |
| «Tweeter Diameter: 0.75 inches» | The identical figure on the JBL Clip 5's listing. It is boilerplate, not a measurement, and the Flex has no separate tweeter. |
| «Frequency Response: 40 hertz» | A single number. 40 Hz would be genuinely impressive from a 590 g speaker, and it is not a response curve either way. |
| Seven years of spare parts | «EU Spare Part Availability Duration: 7 years». It is the longest support commitment published by anything on this site, and it is a real one. |
A summary of the reviews published on Amazon.com as of 2026-09-09.
4.7 out of 5 from 13,021 ratings. Almost every positive review is about sound quality and build; the loop and the silicone shell come up often. The complaints are the price, the absence of an aux input, and buyers who expected more volume than a speaker this size can produce.
