Isotunes built its name on hearing protection, and now it is coming after DeWalt’s pocket-speaker business with an ad that reads the other brand’s spec sheet out loud. The new Sidekick is a clip-on wearable Bluetooth jobsite speaker priced at $99.99, and Isotunes is marketing it head-to-head against DeWalt’s clip-on speaker, which sells for about $58 on Amazon.
The Sidekick Spec Sheet
- Price: $99.99 direct from Isotunes, seen at $80 at Walmart
- Durability: IP67, dust-tight and submersible to 1 meter for 30 minutes, plus MIL-STD-810H testing
- Battery: up to 20 hours, USB-C charging
- Extras: built-in LED light (high/low/strobe), mic for calls, magnetic clip, pair two units for stereo
- In the box: rugged zippered shell case
It is available now from Isotunes.com and Walmart. There is no Amazon listing for the Sidekick yet, which is unusual for a brand that sells most of its lineup there.
Why the Ad Is a Big Deal
Tool brands trade punches in marketing all the time, but a name-on-name attack ad from an audio company aimed at the biggest tool brand on the planet is a different move. The Sidekick ad calls out DeWalt’s IP56 rating, which is dust-protected and splash-resistant but not dust-tight or submersible the way IP67 is. Isotunes also leans on MIL-STD-810H drop testing, though it never states a specific drop height in the ad, which is worth knowing before you take the claim at face value.
The counterpoint: near-identical clip-on speakers from Infurture sell on Amazon for $13 to $26, and their listings predate the Sidekick by months. Whether Isotunes engineered its own unit or badged an off-the-shelf design, the premium is real, and buyers should decide if the IP67 rating and support are worth roughly $60 over the generic versions.
Klein also just launched a speaker that looks a lot like DeWalt’s, so this clip-on form factor is clearly the newest battleground in jobsite audio.
What This Means for Buyers
If you work around water, mud, or concrete dust, the Sidekick’s IP67 rating is a genuine step up from IP56. If your speaker mostly lives on a sawhorse in a dry shop, DeWalt’s $58 unit or one of the $20 generics covers it. And if you already run Isotunes ear protection, pairing one brand means one app ecosystem and one warranty phone number.
