We are excited to introduce the CS50 to you because of its special features that are not provided by other hearing amplifiers.

How can Sound World Solutions CS50 give me a better hearing environment?


“Directionality is the only way to improve intelligibility in noisy environments,” states Stavros Basseas, PhD, co-founder and president of Sound World Solutions who worked as an engineer for two major hearing aid manufacturers during the 1980s and 90s.


It is all just “directionality”. The CS50 focuses on enhance the directionality which helps the user identify the location and direction of the sound sources in different occasions, especially the noisy places including the restaurant.


When using the older version of sound amplifiers, you may find that all the sounds around you, no matter the dog sparks, the car engines noise and the air-conditioners’ running noise, are amplified, These annoying magnified noise make concentration on important sounds, for example, the conservation with your colleagues, the teachers’ saying and the chit-chat with you friends, becomes tough. Even when you gaze the speakers’ mouths, you still cannot understand the speeches. It is a frustrating moment for the users who think the hearing amplifier can help them.


Unlike, the outdated sound amplifiers, the CS50 does a great job in noise reductions. It has 16 noise reduction channel and a dual microphone. With these two features, the CS50 is able to identify the noise surround you and minimize the noise volume as much as possible by the 16 channel compressor.

Advanced setting on sounds


Usually, the sound amplifiers have a pre-manufactured programs for the users. These programs are fixed that does not allow further modification. Perceptions of sound are different to everyone. Some prefer higher and brighter sounds while some prefer softer and lower sounds. It seems normal that you have a board choices of earphones that provides different sound qualities. However, why the programs of hearing amplifiers are fixed stubbornly? Fortunately, the CS50 does not follow this rule. By using the free Customizer app, you can the bass, mild and treble ranges respectively. Of course, you can also adjust the basic functions , such as the volume.


Bluetooth is available on the CS50


In the past, when we want to listening a music and we do not want to bother the others, we have to take off our hearing amplifiers and plug in the earphones. Or, put a headphone on our head so that the speaker is pointing to the microphone of the sound amplifier. The old-style hearing amplifier makes listening to music troublesome. Can the sound amplifier stream music via smartphone directly? The CS50 answers YES. The Bluetooth of the CS50 can steam the songs, radio broadcast via the smartphone. Besides, enjoying the music, you can make call directly too! What’s a great new to the sound amplifiers’ user.


Let’s hear what the users of the CS50 have said


“A friend told me about his experience with Sound World hearing amplifiers, and I purchased mime the next day. I don’t have to say “pardon” all the time and I can hear what is being said in movies or on TV shows. Thanking for making them affordable!”
