Product Overview

The world's highest definition, highest-fidelity, non-custom earplugs, ETY•Plugs® HD from Etymotic Research are a part of their ETY•Plugs HD series. They're designed to quiet most noise to safe levels, while still retaining speech clarity as well as environmental sounds. Notably, they're configured to match the ear canal's natural response, so that when sound comes into the earplug, it's reproduced unaltered and uncolored – precisely as the ear would hear it – only quieter. This particular product is a package that includes a single pair of Standard-size ETY•Plugs HD with either Frost Tips or White Tips (please specify when ordering), along with a handy storage/transport case. Comes in a "polybag" retail package.

Regular usage of these high-fidelity earplugs when involved with higher sound-level events will protect hearing from the cumulative effects of overexposure to loud sounds throughout life. Just as a note, acclimation to these earplugs may take a little time.

Etymotic Research ETY•Plugs HD Includes:

  • ETY•Plugs HD earplugs: (1) Pair Standard earplugs with either Frost or White tips (please specify when ordering)
  • Black neck cord
  • Storage/transport case

Etymotic Research ETY•Plugs HD Features:

  • High-definition hearing protection
  • Comfortable, 3-flange fit designed to seal the ear
  • Reusable and long lasting
  • Detachable cord to prevent loss
  • Comes in Standard size*
    • *NOTE: Studies by Etymotic Research and an independent lab show that the smaller of the 2 sizes fits the majority of ears. Ear size cannot be predicted by the appearance of the outer ear, or by a person's physical size, age, or gender.
  • Performance Benefits:
    • Reduces sound levels evenly so that speech and environmental sounds are clear and natural, not muffled as with foam earplugs
    • Reduces sound approximately 20 dB across the range of hearing
    • Provides enough sound reduction in most settings to protect hearing, but keeps users aware of their surroundings
    • Reduces the potential for hearing damage outside of work from loud machinery, vehicles, power tools, sporting events, and recreational activities
    • Provides better hearing in noisy environments because ears don't overload
    • Reduces fatigue from long-term exposure to noise
    • Not recommended for use with impulse noise, e.g., shooting sports

Etymotic Research's ETY•Plugs HD Specifications:

  • Manufacturer code: ER20-SFT-P
    • ETY•Plugs HD use a tuned resonator and acoustic resistor to replicate the natural response of the ear canal. This unique construction, combined with Etymotic's proprietary sound path, reduces sound levels evenly across the frequency range without altering the sound quality. This results in loud sounds remaining clear, just quieter and safer.
    • ETY•Plugs HD provide nearly equal sound reduction (20 dB) across the range of hearing. Alternately, foam earplugs reduce high frequencies, resulting in muffled speech and music. Frequency response chart shown below:

NOTE:

Due to the personal nature of usage, earplugs are non-returnable.

ETY•Plugs are reusable, but with repeated use, the eartips may lose elasticity, weaken, and break. For best performance and retention, especially if you use your ETY•Plugs constantly, replace them every 3-6 months.

*NOTE: Everyone's ears are different. It's impossible to predict the size of an ear canal judging by the appearance of the outer ear, or by a person's physical size, age, or gender. ETY•Plugs 2 sizes – between them – fit nearly 100% of ear canals. Recent studies of both fit and seal, conducted at Etymotic Research and an independent lab, showed that the smaller of the 2 sizes fits the majority of ears and is now designated as standard fit.
