ToolGuyd argues that ISOtunes’ Sidekick advertising compares its speaker with an older DeWalt model, despite a newer DeWalt wearable speaker with a work light and Auracast. The report also points to similar FCC teardown images for the Sidekick and a much cheaper Infurture speaker, and conflicting Sidekick battery figures; those observations do not establish that the products are identical or verify real-world battery life.

ToolGuyd has published a report challenging ISOtunes’ advertising for its Sidekick clip-on Bluetooth speaker, saying the company compares it with an older DeWalt model while a newer DeWalt speaker offers features used in the ads as points of difference. The report also highlights conflicting battery-capacity figures and matching-looking circuit boards in FCC teardown materials, but it does not independently test the speakers or establish that they are identical.

ToolGuyd says an ISOtunes ad contrasts the Sidekick’s work light with an older DeWalt wearable speaker that lacks one. The report identifies a newer model, the DeWalt Pro Max wearable Bluetooth speaker, which it says includes an LED work light and Auracast for streaming to multiple compatible devices. At the time cited, ToolGuyd listed the Sidekick at about $100 directly or $80 at Walmart, and the Pro Max at about $76 before a coupon, or roughly $67 at checkout. Prices may change.

The report also compares the Sidekick with the Infurture wearable speaker, which ToolGuyd says was selling for $14 in green or $21 in black. ToolGuyd examined FCC-published teardown images and said the Sidekick and Infurture circuit boards appear identical, including a shared version number. That is the publication’s visual assessment; the material provided does not include an independent component analysis or confirmation from either manufacturer that the devices share a design.

Battery information is inconsistent in the source report. ToolGuyd says an FCC teardown image shows a 750 mAh Sidekick battery, while an ISOtunes Walmart listing image gives 600 mAh. The company advertises “up to 20 hours” of use, and, according to ToolGuyd, told a user that runtime varies with factors such as playback volume. The report lists the Infurture at 600 mAh with a 10-hour claim and the DeWalt Pro Max at 700 mAh with an up-to-12-hour claim. These are reported specifications and advertised estimates, not comparable independent battery-test results.

What the Comparisons Mean for Buyers

The report matters to shoppers because price, features and battery life are central to choosing a jobsite speaker. If an ad compares the Sidekick only with an older DeWalt model, buyers may not see the newer model’s work light or multi-device streaming capability in the comparison. ToolGuyd argues that the Pro Max is the more relevant DeWalt counterpart.

The alleged resemblance to a less expensive Infurture speaker also raises a practical value question: what does the Sidekick’s higher price provide? Similar-looking boards in regulatory teardown images may prompt scrutiny, but they do not by themselves show that finished products have the same materials, performance, warranty, durability or support. Those distinctions matter particularly for equipment expected to be used at work.

Battery figures also deserve careful reading. “Up to” runtime is not a guarantee of typical use, and the report itself notes that volume affects playback time. Until the capacity discrepancy is resolved and testing conditions are comparable, the advertised 20-hour figure cannot be treated as a verified head-to-head advantage.

The Older DeWalt Model at Issue

ToolGuyd’s criticism centers on the model selected for ISOtunes’ comparison. The publication says the ad contrasts the Sidekick with an older DeWalt speaker priced around $60 at Amazon, or approximately $53 with a coupon. It says the Pro Max launched months before the Sidekick ads it had seen and presents that newer speaker as a closer comparison because it has a work light and Auracast.

The report also places the devices’ advertised runtimes alongside battery capacities: 10 hours for Infurture at 600 mAh, up to 12 hours for DeWalt Pro Max at 700 mAh, and up to 20 hours for Sidekick at either 600 or 750 mAh depending on the material cited. These figures come from product claims and teardown images, not a controlled test. Battery capacity alone does not determine runtime; playback volume and other device characteristics can affect it.

ToolGuyd disclosed that it may earn an affiliate commission when readers buy through its links. That disclosure is relevant when readers assess the report’s linked prices and recommendations, though it does not resolve the factual questions the article raises.

“One of these has a work light in it.”

Battery Specs and Board Similarity

The source material does not establish whether the Sidekick battery is 600 mAh or 750 mAh. ToolGuyd says those figures appear in different materials: a Walmart listing image and an FCC teardown, respectively. It is also unclear whether the listing image is current or whether the teardown battery shown corresponds to every retail unit.

The matching-looking FCC circuit boards are evidence of visual similarity, not conclusive proof that the Sidekick and Infurture are identical products. No manufacturer response, engineering comparison, or independent teardown assessment is included in the supplied report. The material also does not provide controlled tests of runtime, sound quality, durability or charging performance across the three speakers.

ISOtunes’ intent in choosing the older DeWalt comparison is also unknown. ToolGuyd characterizes the comparison as unfair or misleading, but the source material does not include a response from ISOtunes addressing that criticism. The claims and price listings may change over time.

Responses and Comparable Testing

The key next developments would be a response from ISOtunes on the battery discrepancy, the Sidekick’s relationship to the Infurture design, and the DeWalt model selected in its advertising. The supplied source does not say whether the company has addressed those questions or plans to revise its product materials.

For buyers comparing these speakers, the unresolved points call for checking current product pages and specifications, including which DeWalt model is being discussed. A meaningful runtime comparison would require testing the devices under the same volume, audio and operating conditions. Until that information is available, ToolGuyd’s findings are best understood as questions about the ads and published specifications, rather than a final finding about comparative performance.

Key Questions

What is ToolGuyd’s main criticism of the Sidekick advertising?

ToolGuyd says ISOtunes compares the Sidekick with an older DeWalt speaker even though a newer DeWalt Pro Max model has a work light and Auracast, features relevant to the ad’s comparisons.

Is the Sidekick battery 600 mAh or 750 mAh?

The report cites both figures: 600 mAh in a Walmart listing image and 750 mAh on a battery shown in FCC teardown material. The supplied information does not resolve the discrepancy.

Has testing confirmed the Sidekick lasts 20 hours?

No independent comparative test is included. ISOtunes advertises up to 20 hours, while the report says runtime varies with playback volume.

Does the FCC material prove the Sidekick and Infurture are identical?

No. ToolGuyd says their FCC teardown circuit boards appear identical, but that visual comparison alone does not establish that the complete products, components or performance are the same.

How much does the Sidekick cost compared with the Infurture?

At the prices cited in the report, the Sidekick was about $80 at Walmart or $100 directly, while the Infurture was listed at $14 in green or $21 in black. Prices can change, and the source does not establish whether the products offer equivalent performance or support.
