ToolGuyd argues that Isotunes’ Sidekick clip-on Bluetooth speaker is difficult to justify at its listed $80–$100 price, pointing to a much cheaper Infurture speaker and a newer DeWalt model with a work light. Its report cites FCC teardown images and conflicting battery-capacity figures, but does not establish that the products are identical or independently verify runtime claims.
ToolGuyd has questioned whether Isotunes’ Sidekick clip-on Bluetooth speaker offers enough to justify its reported $80–$100 price, arguing that the company’s DeWalt comparisons leave out a newer rival and that FCC teardown images show a low-cost Infurture speaker with a similar-looking circuit board. The report raises questions about product value and battery claims, but it does not independently establish that the speakers are identical or test their real-world performance.
ToolGuyd says Isotunes’ advertising compares the Sidekick with an older DeWalt wearable Bluetooth speaker, which the report lists at about $53 with a coupon from a $60 retail price. It points instead to DeWalt’s newer Pro Max wearable speaker, which ToolGuyd says costs about $67 after a coupon and includes an LED work light. According to the report, the newer model also supports Auracast, a feature for streaming audio to multiple compatible devices.
The report lists the Sidekick at about $100 from Isotunes or $80 through Walmart. It compares those prices with an Infurture wearable speaker listed at $14 in green or $21 in black on Amazon. ToolGuyd says FCC teardown images show the Infurture and Sidekick circuit boards and components appearing identical, including a matching board version number. Those images form the basis of the report’s comparison; they do not, on their own, establish that the finished products have identical performance, materials, software or quality control.
Battery information is inconsistent in the material reviewed by ToolGuyd. The report says the FCC teardown image shows a 750 mAh Sidekick battery, while an image on Isotunes’ Walmart listing gives a capacity of 600 mAh. It also cites advertised runtimes of up to 20 hours for the Sidekick, 10 hours for the Infurture and up to 12 hours for the newer DeWalt. ToolGuyd notes that Isotunes’ listing ties its stated 20-hour maximum to playback at 25% volume and gives nine hours at 50%.
What Buyers Get for the Price
The dispute matters to buyers comparing compact speakers for work because price, battery life and practical features can shape whether a premium product makes sense. If the less expensive models provide comparable everyday use, shoppers may want to weigh the Sidekick’s price against its work-light and connectivity features rather than relying on a comparison with an older DeWalt product alone.
ToolGuyd’s report is a product critique, not a controlled test. Similar-looking boards and different advertised battery capacities do not prove that speakers have equal sound, durability, support or performance. The report also does not quantify how often buyers would use Auracast or the work light. Those gaps leave readers with useful questions to investigate, rather than a definitive finding that the Sidekick is or is not worth buying.

The DeWalt Comparison at Issue
ToolGuyd says Isotunes’ advertising highlights that the Sidekick has a work light while the older DeWalt speaker does not. The report argues that this is an incomplete comparison because a newer DeWalt Pro Max wearable speaker had already launched before the Sidekick advertising campaign discussed in the article. According to ToolGuyd, that newer DeWalt model also has a work light and Auracast support.
The report separately compares teardown images for the Sidekick and Infurture speaker, which it says was on sale before the Sidekick. It describes the boards as appearing identical, but offers no independent teardown testing or confirmation from either manufacturer about shared components. The article also discloses that ToolGuyd may earn an affiliate commission if readers purchase through its links, a relevant consideration when weighing its product recommendations and pricing references.

Battery Figures and Board Similarities
The source report does not resolve why the Sidekick battery is listed as 600 mAh in one place and 750 mAh in another. It also does not present independent, like-for-like runtime tests for the Sidekick, Infurture and DeWalt speakers. Battery capacity and advertised maximum hours cannot by themselves establish how long each model lasts under the same volume and usage conditions.
It remains unclear whether the apparent similarities in the FCC images reflect shared components, a common design, or other manufacturing relationships. The report does not include confirmation from Isotunes, Infurture or DeWalt about the boards, product sourcing or differences in sound, durability, warranty and support. Prices cited are the report’s observed listings and may change.

Questions for Isotunes and Buyers
The supplied report does not describe a response from Isotunes to its questions about the battery-capacity discrepancy or the Sidekick’s comparison with the newer DeWalt model. Further clarification from the company, or independent tests using consistent volume and playback conditions, could help establish how the products compare. Until then, shoppers can check current prices and specifications and decide how much they value the Sidekick’s stated features alongside the unresolved runtime and teardown questions.

Key Questions
What is the main criticism of the Isotunes Sidekick?
ToolGuyd argues that its $80–$100 price is hard to justify when a cheaper Infurture speaker appears similar in FCC teardown images, and says Isotunes’ DeWalt comparison omits a newer model.
Does the newer DeWalt speaker have a work light?
According to ToolGuyd, the DeWalt Pro Max wearable speaker has an LED work light and Auracast support. The report lists its price at about $67 after a coupon at the time it was written.
How long does the Sidekick battery last?
Isotunes advertises up to 20 hours, but ToolGuyd says the listing specifies 20 hours at 25% volume and nine hours at 50%. The report does not provide an independent runtime test.
Are the Sidekick and Infurture speaker the same product?
ToolGuyd says their FCC teardown images show circuit boards and components that appear identical. That visual comparison does not confirm that the finished speakers are the same or perform equally.
Why do the Sidekick battery figures differ?
ToolGuyd reports seeing 750 mAh in an FCC teardown image and 600 mAh in an image on Isotunes’ Walmart listing. The source does not explain the discrepancy.
