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.

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)||38.4||40.3||43.2||41.8||38.6||45.0||45.7||49.6||47.3|
|Standard Deviation (dB)||2.9||3.5||4.0||3.8||2.6||2.8||3.5||3.8||4.3|
- The environmental noise level as measured at the ear is 92 decibels dB(A).
- The NRR is 32 decibels (dB).
- The level of the noise entering the ear is approximately 60 dB(A).
Noise Reduction Rating 32 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).
Ear plugs must be inserted properly for optimum performance.
- With clean hands, firmly roll entire ear plug between thumb and fingers to form a thin tight cylinder.
- Using one hand, gently lift top of ear up to open ear canal. With other hand, insert rounded end of ear plug.
- With forefinger, hold ear plug in place until expands to form a comfortable, snug fit.
Practice of insertion is recommended. Discard product after several uses or as soon as dirt or wax accumulates on ear plugs.
Caution: Keep away from infants. This product is non-toxic but may interfere with breathing if caught in windpipe.
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 accurate indicator of the protection attainable impulsive noise such as gunfire. The Noise Reduction Rating (NRR) calculated from the attention data is 32dB. Ear plugs must be properly fitted to attenuate noise effectively. Refer to instructions.
iHerb Customer Reviews
These ea plugs are the best of any plugs I used for the last 15 years. I don't hear snorring husband, morning namaz from neighboring mosque, street traffic, jet motors noise at an airplane - the only problem is to hear morning alarm clock)))) It is delicate and soft, reasonable size. Definetly I will repeat this purchase.
I live in central London, UK, and can honestly say that Hearos Ultimate Softness are the best earplugs on the world market for my purposes. I don't have a serious noise problem but for the occasional parties in the apartment above me, Hearos are the answer - blissful silence every time! They are comfortable and noise resistant.
