Moldex 6770 Flip-to-Listen Corded Reusable Earplugs — NRR 24 dB Overview
The Moldex 6770 Flip-to-Listen is a corded, reusable flanged earplug built for workers who need to block noise on the line and then hear a coworker, a radio call, or a backup alarm without pulling the plug out. A pivot stem flips the plug between a closed mode (full attenuation) and an open mode (hear-through), so you keep one device in your ear through quiet and loud cycles. It carries a Noise Reduction Rating of NRR 24 dB tested to ANSI S3.19 in closed mode.
Treat the 24 dB label as a laboratory ceiling, not your real-world result. OSHA's standard derate is (NRR − 7) / 2 for a mixed assumed-protection estimate, which puts the 6770 near ~8–9 dB of practical attenuation; NIOSH applies a 25% derate to the labeled NRR for well-fitted flanged plugs. Under OSHA 1910.95 hearing conservation, the 85 dBA action level triggers a monitoring and protection program and the 90 dBA PEL is the enforceable limit, so confirm your measured exposure before relying on any single plug. See what is NRR and how to calculate NRR to match the 6770 to your dBA.
As a reusable flanged plug, the 6770 wipes clean and goes back in service rather than getting tossed each shift, and the permanently attached cord keeps the pair around your neck between uses. It is a corded, hear-through option within our reusable ear plugs and corded ear plugs ranges. If your environment runs steady high-dBA with no need to converse, a higher-rated foam plug from our foam ear plugs may suit better — compare options across hearing protection.
What It Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Intermittent noise with frequent talking | Excellent | Flip to open mode to hear coworkers or radio, flip closed when the machine runs — no removal needed. |
| Steady moderate noise 85–95 dBA | Good | NRR 24 in closed mode covers typical action-level to PEL exposure once derated; verify against your measured dBA. |
| Sustained very high noise above 100 dBA | Limited | Derated ~8–9 dB may be insufficient; step up to a higher-NRR foam plug or dual protection. |
| Reusable plug for repeat daily wear | Excellent | Washable flanged body and attached cord make it a keep-on-hand alternative to single-use foam. |
| Sleeping or concert use | Poor | This is an industrial PPE earplug; the corded hear-through design is built for the worksite, not rest or music. |
Earplugs reduce noise, but the labeled NRR is a laboratory number — real-world protection is lower. NIOSH derates foam by about 25%, and OSHA estimates protection as (NRR − 7) ÷ 2. Under OSHA 29 CFR 1910.95 a hearing-conservation program is required at an 8-hour TWA of 85 dBA. Insert foam plugs correctly (roll, pull the ear up and back, hold) for the rated seal, and use dual protection with earmuffs in very high noise. See how to calculate the NRR you need.
Pros & Cons
Pros
- Dual-mode flip stem switches between block and hear-through without removing the plug
- Reusable, washable flanged body lowers per-use cost vs single-use foam
- Permanently attached cord keeps the pair handy and reduces drops
- NRR 24 dB (ANSI S3.19) suits common 85–95 dBA action-level exposures after derating
- Pre-molded flanges insert without rolling down like foam
Cons
- NRR 24 is mid-range; derated protection (~8–9 dB) may fall short above ~100 dBA
- Open hear-through mode reduces attenuation — must be flipped closed in loud cycles
- Flanged fit suits most but not all ear canals; not as conformable as foam
- Cord can snag on equipment in some tasks
How It Compares
Within Moldex and our corded/reusable lineup, the 6770 is the hear-through specialist — most siblings trade the flip mode for higher fixed attenuation:
| Model | NRR | Form / cord | Best for |
|---|---|---|---|
| Moldex 6770 Flip-to-Listen | 24 dB | Reusable flanged, corded, dual-mode | Block then hear without removing the plug |
| Moldex 6985 Glide Soothers (corded) | 31 dB | Disposable foam, corded | Higher fixed attenuation, single-use comfort |
| Moldex Rockets 6480 (reusable) | 27 dB | Reusable flanged, uncorded | Reusable flanged with higher NRR, no cord |
| 3M 1270 reusable corded | 25 dB | Reusable multi-flange, corded | Similar corded reusable without flip mode |
Need maximum block in steady noise instead of hear-through? See our highest-NRR ear plugs guide.

Frequently Asked Questions
What is the NRR of the Moldex 6770 Flip-to-Listen?
It is rated NRR 24 dB in closed mode, tested to ANSI S3.19. After OSHA's (NRR−7)/2 derate that is roughly 8–9 dB of practical attenuation, so verify against your measured dBA. See our what is NRR guide.
How does the Flip-to-Listen dual mode work?
A pivot stem flips the plug between a closed mode for full attenuation and an open mode that lets you hear speech, radio, or alarms — all without removing the plug from your ear.
Is the Moldex 6770 corded or uncorded?
Corded. It has a permanently attached cord that keeps the pair together around your neck between uses, which helps prevent drops. Browse more corded ear plugs.
Are these earplugs reusable or single-use?
They are reusable. The pre-molded flanged body wipes clean and goes back in service, unlike single-use foam. See our full reusable ear plugs range.
Will NRR 24 protect me at my noise level?
It depends on your measured exposure. NRR 24 derated lands near 8–9 dB of real-world protection, which suits many 85–95 dBA tasks. Use how to calculate NRR to confirm.
Do these meet OSHA hearing conservation requirements?
OSHA 1910.95 sets an 85 dBA action level and a 90 dBA PEL. The 6770 can be part of a compliant program once you confirm derated attenuation covers your exposure. See OSHA 1910.95 hearing conservation.
How do I get a proper fit with flanged earplugs?
Reach over your head, pull the ear up and out, and push the flanges in until they seal. Flanged plugs do not roll down like foam, but a good seal is still essential to reach the labeled NRR.
How is real-world protection different from the NRR 24 label?
Lab NRR overstates field results. OSHA applies (NRR−7)/2 and NIOSH applies a 25% derate for flanged plugs, both of which lower the effective protection below 24 dB. Always size protection to your actual dBA.
How do the 6770 compare to higher-NRR Moldex plugs?
The 6770's edge is the flip-to-listen mode at NRR 24. If you need higher fixed attenuation, the corded Moldex 6985 Glide Soothers (NRR 31) or reusable Moldex Rockets 6480 (NRR 27) block more but lack hear-through.
Can I clean and reuse these between shifts?
Yes. Wash the flanged body with mild soap and water, let it dry, and reinspect for damage before reuse. Replace plugs that are torn, hardened, or no longer seal.
Should I choose the 6770 or foam earplugs?
Choose the 6770 if you need to switch between blocking and hearing without removing the plug. For steady high noise with no need to converse, a higher-NRR option from our foam ear plugs may protect more.
Are earplugs or earmuffs better for my job?
It depends on noise level, duration, and whether you also need head protection or frequent on/off use. Compare trade-offs in our ear plugs vs ear muffs guide, then browse all hearing protection.
