The DEWALT DPG660 Dielectric Cap-Mount Earmuff is a hearing protector designed for workers who need dependable noise reduction in environments where metal-free materials matter. Its NRR 25 rating and dielectric construction make it a practical choice for work near electrical hazards, while the padded earcups and adjustable 4-point suspension keep it comfortable through long shifts.
Working near energized equipment demands extra caution. The DPG660's dielectric construction contains no metal, so it won't conduct electricity. That makes it a strong choice for electricians, utility workers, and anyone doing overhead work near cables. The NRR 25 sound reduction helps keep noise levels manageable without completely isolating you from your surroundings.
The expandable arms and 4-point suspension distribute pressure evenly around your head, so you won't feel hot spots after an hour of wear. The padded ear cups soften contact, and the foldable arms make it easy to tuck into a tool bag when not in use.
Mounting takes seconds: attach the arm brackets to your cap and adjust the height until the earcups seal around your ears. If the ear cushions wear out, replacement cushions and parts are available so your DPG660 stays functional for years instead of getting tossed.
It's a solid pick for professional tradesmen, utility crews, and serious DIYers who already wear a hard hat and want continuous hearing protection without buying a helmet-integrated unit. It's also a convenient backup for visitors and helpers on job sites with moderate noise levels.

Not all hearing protection is safe around electricity. Metal components can conduct current if you brush against a live part, turning an ordinary earmuff into a hazard. The DEWALT DPG660's dielectric design uses metal-free materials to keep you safer on the job.
The arm brackets click onto most hard hats and let you adjust the height and angle for a proper seal. Even with safety glasses or a face shield, the low-profile cups fit comfortably.
With basic care and occasional cushion replacement, the DPG660 can serve you for years. That's an honest value for a PPE item.

These muffs fit perfectly on my hard hat. They're comfortable and block out a lot of noise. I wear them all day.
They work well but are a bit tight over my ears.
I forget I'm wearing them. The noise reduction is excellent. They attach securely to my cap.
They get the job done. The foam is a little stiff at first.
These are the best cap-mounted muffs I've used. The NRR 25 rating is accurate. They don't interfere with safety glasses. I've bought three pairs for my crew.
Great muffs.
They are okay. The cushion could be softer.
