PROHEAR 037BR04 Bluetooth Hard Hat Earmuffs: quick answers

Protection: SNR 30 dB, the European figure. A US NRR is not stated for this model, and the two numbers are not interchangeable.
Power: Rechargeable, 1,100 mAh; up to 40 hours stated.
Audio: Bluetooth 6.0 for calls and music.
Fits: 3M H-700 and DEWALT hard hats with accessory slots.

The 037BR04 is the 037 built for a hard hat: no band, just two cups on adapters that clip into the accessory slots of a 3M H-700 or a DEWALT hard hat. The hat holds them in place, so there is no band over your head.

Bluetooth 6.0, a 1,100 mAh battery rated for up to 40 hours, SNR 30 dB. The hard hat is not included.

Every work & bluetooth model sits in the PROHEAR selection; the numbers on this page come from the model’s own box and spec sheet.

This is general information about hearing protection, not medical or safety advice. The rating printed on the package, a proper fit and your employer's hearing conservation rules come first; see a doctor or an audiologist about ringing or a change in hearing.

What the public sources say

EPA, 40 CFR Part 211 Subpart B: Hearing Protective Devices. Requires the Noise Reduction Rating on the package, measured to ANSI S3.19-1974, and gives the label range as approximately 0 to 30. Read October 4, 2026.
OSHA, 29 CFR 1910.95 Occupational noise exposure. Sets 90 dBA over eight hours as the limit, starts a hearing conservation program at 85 dBA, caps impulse noise at 140 dB peak and has employers offer a choice of protectors. Read October 4, 2026.
OSHA, 1910.95 Appendix B: Methods for estimating the adequacy of hearing protector attenuation. For A-weighted readings, subtract 7 dB from the NRR; the estimate holds only for a protector that is properly fitted and worn. Read October 4, 2026.
NIOSH, About Occupational Hearing Loss. Recommends 85 dBA as the exposure limit and says noise-induced hearing loss is permanent but nearly always preventable. Read October 4, 2026.
