By Hearos7 Reviews
The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.
The Shipping Weight includes the product, protective packaging material and the actual shipping box. In addition, the Shipping Weight may be adjusted for the Dimensional Weight (e.g. length, width & height) of a package. It is important to note that certain types of products (e.g. glass containers, liquids, fragile, refrigerated or ice packed) will often require protective packaging material. As such, these products will reflect a higher Shipping Weight compared to the unprotected product.

Tested according to ANSI Specs S3.19-1974
The level of noise entering a person's ear, when hearing protector is worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the NRR.
|Attenuation Chart (ANSI S3.19-1974)|
|Mean Attenuation (dB)||34.5||35.5||37.4||34.4||37.8||40.7||40.9||43.1||45.4|
|Standard Deviation (dB)||5.6||5.4||5.1||4.1||4.0||4.6||3.8||3.7||2.6|
- The environmental noise level as measured at the ear is 92 decibels dB(A).
- The NRR is 27 decibels (dB).
- The level of the noise entering the ear is approximately 65 dB (A).
Noise Reduction Rating 27 Decibels (When Used As Directed).
The range of noise reduction ratings for existing hearing protectors is approximately 0 to 30. (Higher numbers denote greater effectiveness).
Using one hand, gently lift top of ear up as shown to expand ear canal. With other hand, use stem to guide ear plug into a comfortable position. If necessary, adjust ear plug for enhanced sealing performance.
Cleaning: Wash with mild soap and water. Dry thoroughly before re-insertion into ear.
Important: No diving. Not recommended for depths over 5 feet. Store ear plugs in keychain case to keep clean.
Note: If ear plugs become cut, cracked or unpliable, replace with a new HEAROS ear plug. Not intended for sleeping or any applications where pressure could be applied against stem.
Caution: Keep away from infants. This product is non-toxic but may interfere with breathing if caught in windpipe.
Remove slowly with twisting motion to gradually break seal. Due to the excellent seal characteristics, rapid removal may damage ear drum.
For noise environments dominated by frequencies below 500 Hz, the C-weighted environmental noise level should be used. Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the above instructions for proper fit. Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the Noise Reduction Rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise such as gunfire.
The Noise Reduction Rating (NRR) calculated from the attenuation data is 27dB. HEAROS ear plugs must be properly fitted to attenuate noise effectively. Refer to instructions.
iHerb Customer Reviews
The plugs have been purchased for my 5 years old daughter. They appeared to be too big for her ears and keep falling out. Seem to me they are not really suitable for the little kids, should be a bit smaller.
I have had grommets , these have just been fantastic. Just received the newer ones and they are even better. Very easy to use.
