OHROPAX is the Chinese brand name of OHROPAX, a well-known German manufacturer of hearing protection products. OHROPAX, which means calm of the ear, originated from the Max Negwer Pharmaceutical and Cosmetics Specialty Factory, founded in 1907, and was originally the name of wax pill soundproof earplugs. During World War I, OHROPAX was supplied in bulk to soldiers to protect their ears from the sound of artillery fire. In 1928, OHROPAX became the most famous German hearing protection brand, exported to 42 countries around the world, and in 1991 began to adopt a modern production and packaging system, and has produced more than 30 million sound-isolating earplugs per year.
 
The earbuds are packaged in Chinese, and the products are imported from Germany, which is no different from OHROPAX products sold abroad. There are not many consumers who have the habit of using soundproof earbuds in China, and the soundproof earbuds market is dominated by foreign brands, and Ann Ear has entered the Chinese market for many years, although there are fewer styles, but it also takes into account the comfortable type, small ear canal type and super sound insulation type, with good sound insulation effect and stable quality control, making it one of the most popular soundproof earbud brands in China.
 
The best-selling Soft Sound Isolation Earbuds are made of high-quality PU foam, with obvious small holes on the surface, and a loose texture, using a sound insulation strategy of noise isolation and noise absorption, the sound insulation effect can reach SNR32dB, and the rebound speed is slow, which is easy to adjust and adapt. The Soft Sound-isolating earbuds are also bullet-shaped, but with a slower arc and a softly rounded head, unlike Mack's, which uses a pointed head to accommodate deeper into the narrower ear canal, making it possible to feel swollen when used for long periods of time. Its bright skin tone appearance is convenient to observe the use, and the official claim is that it can be cleaned after being dirty, but in actual use, washing with water may cause rebound failure, and it is necessary to pay attention to using clean water to carefully wash or replace it directly. The maximum size is 5 pairs in a box, and there is no independent packaging, which is a little inconvenient for storage. Each pair costs about $5 and can be used for about 2 months.
 
If you have a small ear canal and feel that the size of the Soft Sound Isolation Earbuds is too large, the discomfort of wearing them for a long time is strong, or if you have never used Sound Isolation Earbuds, you can consider buying a smaller size first. Designed for people with small ear canals, the Mini Soft is very eye-catching, with a streamlined appearance that mimics the ear canal and a yellow-green color scheme, the smaller size will not have a strong feeling of ear swelling, and it is not easy to feel pain or slip out of the ear canal when wearing it for a long time while sleeping. The foam texture of Mini Soft is more delicate than that of Soft, and the nominal noise reduction ability reaches SNR35dB, but if you can't fill the ear canal because of its small size, the sound insulation effect will be weaker than that of the Soft model, which is more suitable for people who are not too noisy in the environment, have a small ear canal and pay attention to comfort. About $8 per pair.
 
The Classic Wax Pill Soundproof Earbuds are the most classic and traditional products of Ann Eryou, which have been sold since their introduction in 1907. It is made of paraffin, petroleum jelly and cotton as the main raw materials, and is a moldable soundproof earbud, which needs to be removed from the cotton wool wrapped around the wax pill when used for the first time, and then kneaded the wax pill into a spherical shape, filled into the outer ear to seal the ear canal, and cannot be directly plugged into the ear canal. It can also be resized by tearing the wax pills according to individual needs, but due to the brittle nature of the wax pills, the wax pill fragments may get into the ears. The noise reduction value of wax pill soundproof earbuds is about SNR27, which cannot achieve the strong sound insulation effect of PU foam, which is similar to Mack's Pillow Soft made of silicone resin, but the wax pill composition contains sticky grease, which is difficult to clean and slightly inconvenient to use. The wax pill soundproof earbuds can be reused several times, about 5 yuan per pair.
