Originating from the United States, Belltone introduced the first behind-the-ear hearing aid in 1958. Products and services throughout the world countries and regions, the main market for North America, and ReSound belongs to the Danish GN Great North Group, the two form a good complementarity in market distribution.
 
The core technology of Beltone's hearing aids is the combination of digital sound processing system and wide dynamic range compression technology to simulate the operation mode of the human ear and bring a more natural and comfortable listening experience. Belton's customized machine adopts open ear technology and adds ventilation holes, which can effectively reduce the feeling of wearing stuffiness.
 
The Bode series for severe and very severe patients is one of the most powerful hearing aids on the market, which can effectively eliminate acoustic feedback, using 675 zinc-air batteries, both 6800 yuan economic version, and 10900 yuan high-end version, compared with many first-line manufacturers' products, it can be described as inexpensive.
 
Compared with the behind-the-ear type, Belton's customized machines account for a relatively heavy proportion. In its long historical development, stable technical investment has enabled its product performance to keep up with the pace of international first-line brands. In the domestic market, it cooperates with well-known hearing aid chain service organizations, and there are many offline stores across the country that can realize fitting and purchasing.
