ToolGuyd published a critical report arguing that ISOtunes’ Sidekick speaker ads use an outdated DeWalt comparison and that the product’s battery and runtime claims need clarification. The report also compares FCC teardown images of the Sidekick and a much cheaper Infurture speaker, but the images alone do not establish that the products are identical or explain their performance.
ToolGuyd has criticized ISOtunes’ Sidekick Bluetooth speaker advertising, saying the company’s comparisons with DeWalt omit a newer DeWalt wearable model and that published battery details appear inconsistent. The report raises questions for buyers comparing jobsite speakers, but it does not establish that ISOtunes’ claims are false or that the Sidekick and a lower-priced speaker are the same product.
ToolGuyd says ISOtunes’ ads contrast the Sidekick, priced in the report at about $100 directly or $80 at Walmart, with an older DeWalt wearable speaker that lacks a work light. The report points to the DeWalt Pro Max, a newer model that it says has an LED work light and Auracast audio sharing. ToolGuyd lists its price at about $76 before a coupon, or roughly $67 at checkout, when the report was written. Prices can change.
The report also questions the Sidekick’s advertised “up to 20 hours” of runtime. It compares battery information for several speakers: 600 mAh for the Infurture model, 700 mAh for DeWalt Pro Max and either 600 or 750 mAh for the Sidekick, depending on the material cited. ToolGuyd says an FCC teardown image of the Sidekick battery shows 750 mAh, while an image on ISOtunes’ Walmart listing specifies 600 mAh. The listing image, as described by ToolGuyd, says runtime is 20 hours at 25% volume and nine hours at 50%.
ToolGuyd also juxtaposes FCC-published circuit-board images for the Sidekick and Infurture wearable speaker, which it says appear identical and carry the same board version number. The report says the Infurture sells for about $14 to $21, depending on color. These observations are the author’s reading of the images; the report does not include independent testing, a manufacturer explanation of the hardware, or evidence establishing that the speakers share all components or performance.
What Buyers Need to Compare
The dispute matters because advertising comparisons can shape buying decisions, particularly when a product is marketed for worksite use and promoted on runtime, lighting and audio-sharing features. If an ad compares a newer product with an older competitor model, shoppers may not see the closest available alternative. ToolGuyd argues that the Pro Max is a more relevant DeWalt comparison because it has features the ad says the Sidekick offers.
The battery discrepancy also complicates a direct comparison of advertised runtime. Capacity alone does not determine how long a speaker plays: volume, audio content, electronics and test conditions can affect results. ToolGuyd reports that ISOtunes told a commenter runtime depends on factors including playback volume, but the source material does not provide a standardized test comparing the speakers. Buyers should treat “up to” figures as manufacturer claims, not a guarantee of runtime under every use condition.
The price gap makes the hardware comparison relevant, too. Similar-looking boards may prompt questions about what a higher-priced product offers, but the teardown images do not settle those questions. Differences in materials, tuning, durability, warranty, support or testing are not addressed in the report. The available evidence therefore supports scrutiny of the claims, not a definitive conclusion about value or product equivalence.

The Models Behind the Dispute
ToolGuyd frames its report around ISOtunes’ promotional comparisons between the Sidekick and an older DeWalt wearable speaker. It says the DeWalt Pro Max launched months before the Sidekick advertising campaign it had seen. The report argues that a model with a work light and Auracast is a closer match for comparing features, while noting that the older DeWalt model costs less.
Separately, the report compares the Sidekick with the Infurture wearable speaker, citing close visual similarities and FCC teardown photographs. ToolGuyd says the Infurture appeared on the market earlier and that FCC materials show board images it considers alike. The source also contrasts advertised battery capacities and runtimes: Infurture at 600 mAh and 10 hours, DeWalt Pro Max at 700 mAh and up to 12 hours, and ISOtunes at either 600 or 750 mAh and up to 20 hours. Those figures come from product materials or teardown images described in the report, rather than a shared independent test.
“One of these has a work light in it.”

Battery Figures Need Clarification
The source report does not establish why the Sidekick battery is listed as 600 mAh in one product image and 750 mAh in an FCC teardown image. It is also unclear whether the materials refer to different versions, whether the listing image is current, or whether one figure is an error. ISOtunes’ explanation of the discrepancy is not included.
There is no independent, controlled runtime test in the report, so the claimed 20-hour maximum cannot be directly compared with the other products’ advertised figures. Nor do FCC photographs alone establish that the Sidekick and Infurture have identical finished products, features or performance. The report says their circuit boards appear the same, but does not provide manufacturer confirmation or a full component-by-component analysis.
ToolGuyd characterizes ISOtunes’ ads as unfair or misleading and suggests the comparisons may rely on cherry-picking or false equivalence. Those are the report’s conclusions. The source does not include a response from ISOtunes addressing the advertising criticism, the battery figures or the teardown comparison.
Manufacturer Response and Testing
The next useful developments would be an ISOtunes explanation of the two battery-capacity figures and clarification of the conditions behind its 20-hour runtime claim. A response addressing why its ads use the older DeWalt model, rather than the Pro Max, would also speak directly to ToolGuyd’s criticism.
For buyers, a controlled test using the same volume and playback conditions would provide a firmer basis for comparing runtime. Until then, shoppers can check the current product specifications and compare features, price, warranty and worksite requirements rather than relying on maximum-runtime claims alone. The source material does not identify a planned company statement, product update or regulatory action.
Key Questions
What is ToolGuyd’s main criticism of the Sidekick advertising?
ToolGuyd says the ads compare the Sidekick with an older DeWalt speaker even though the newer DeWalt Pro Max has a work light and Auracast, features relevant to the comparison.
What battery capacity does the Sidekick have?
The source report cites conflicting figures: 600 mAh in an image on ISOtunes’ Walmart listing and 750 mAh on a battery shown in an FCC teardown image. The reason for the discrepancy is not established in the report.
Has the Sidekick been independently shown to last 20 hours?
Not in the source material. ISOtunes advertises up to 20 hours, and the report describes listing information tying runtime to volume, but it provides no independent, controlled test of the claim.
Are the ISOtunes Sidekick and Infurture speaker the same product?
ToolGuyd says their FCC circuit-board images appear identical and show the same board version number. That observation does not by itself establish that the complete products, performance or specifications are identical.
Has ISOtunes responded to the report’s broader criticism?
The source material includes an ISOtunes response about runtime varying with factors such as volume. It does not include a response addressing the advertising comparison, battery discrepancy or board images.
