PROHEAR 033 Bluetooth AM/FM Radio Earmuffs: quick answers

Protection: NRR 25 dB on the package (SNR 31 dB in Europe). A lab figure: NRR explained shows how OSHA reads it.
Power: Rechargeable, 1,500 mAh; up to 50 hours stated.
Audio: Bluetooth 5.4 for calls and music.
Options: 4 colors plus 1 two-color option, 2 pad types, 4 sets.

The 033 does three things: AM/FM radio, Bluetooth 5.4 and hearing protection rated NRR 25 dB. It stores up to ten AM and ten FM stations, so your station comes back with one press.

A 1,500 mAh battery gives about 50 hours on a charge, through USB-C on the current version. You can choose gel cushions, several colors, the 2.0 version or a 2-pack.

Every work & bluetooth model sits in the PROHEAR catalog; 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.

How much noise does the PROHEAR 033 Bluetooth AM/FM Radio Earmuffs block?

Its Noise Reduction Rating is 25 dB, measured in a lab to ANSI S3.19-1974. On a real head a muff usually blocks less than the lab figure: OSHA subtracts 7 dB from the NRR when noise is measured in dBA, and NIOSH now recommends checking the protection each wearer actually gets. Our NRR guide walks through both.
