The Hansaton Sound FS 1 R 312 in review
This test report is about the Sound FS 1 R 312. It was developed by Hansaton and covers light, medium, and stronger hearing needs. This variant is worn behind the ear. The Sound FS 1 R 312 is a discreet hearing aid at a relatively affordable price. We achieve clear sound transmission by placing the small speaker in the ear canal.
Hearing comfort
First, we assess the hearing comfort features. What types of sounds does the hearing aid recognize? How does it handle them? Is the hearing aid suitable for a varied everyday life? Here, with this test device, a solid comfort programming by the hearing care professional is possible. As with all hearing aids, we also find the typical noise reduction here. It aims to reduce monotonous, noisy ambient sounds to the point where they no longer stand out. With the Sound FS 1 R 312, we have a fairly simple type of noise suppression that should be sufficient for normal environments.
Wind noise is always a topic when the hearing aid microphones are a bit exposed. With the Sound FS 1 R 312, this is no problem at all, as it features intelligent, effective wind noise suppression. This not only mitigates audible turbulence but also preserves speech understanding. Moreover, we are surprised at how well the impulse noise management works here. Nothing crashes, nothing rattles – very good! A few more frequency channels would be desirable, but with the existing 12 channels, it is already quite manageable. In our tests, we also examine spatial hearing. Although adaptive microphones are integrated here, the wireless connection between both ears is missing, which prevents true 3D hearing from being reconstructed. Nevertheless, one can cope well. With a little practice, directional hearing can be retrained.
Interestingly, artificial intelligence also plays a role in the signal processing here. The sound is thus analyzed not only based on typical frequency patterns. Especially in intense, noisy situations, this is perceived as more realistic and pleasant.
Rating Hearing comfort: 2,5
Operation & connectivity
Would you like to be able to adjust something on your hearing aids yourself? We believe it's quite useful to have one or two control options. Let's take a look at how this works with the Sound FS 1 R 312. The simplest control option is always a button directly on the hearing aid. This one has that too. It can be programmed according to your wishes. Do you want a manual volume control? No problem, the button allows for a step-by-step adjustment of the volume. Or do you need different special programs for your professional life or hobbies? These can also be activated via the button. Anyone who prefers to leave everything in automatic mode can simply ignore the button or even have it deactivated. A very practical option is the small remote control, which is available optionally. For us, it is one of the most convenient ways to adjust the hearing aid louder or quieter or switch to another hearing program. No one notices it, and reaching for the ear is not necessary.
In our test, we found no option for voice control. This function is not necessarily required, but we would have appreciated it. Besides buttons or remote controls, some hearing aids also have tap control. This means you can simply tap your ear briefly, and the device switches. However, we don't have that here at Hansaton; it would have required specific sensors.
As is common today, we also find a smartphone app for the Sound FS 1 R 312. This app contains solid basic functions and adds a few extra goodies. The Sound FS 1 comes with a 2.4 GHz antenna and allows us to enjoy stereo phone calls. This actually gives us an advantage over normally hearing individuals. We find that great and are happy to give it points.
Rating Operation & connectivity: 1,8

Simplicity & security
Next we continue with the test: How is the user-friendliness? Is it easy or complicated to handle the hearing aid? When it comes to adapting to changing hearing situations, we have to limit ourselves to the manual options with the Sound FS 1 R 312. An automatic situation recognition would definitely have made life easier, but it is not available here. Very important in terms of simplicity for us is the support during the acclimatization process. Especially after having heard poorly for years, it can sometimes be difficult to perceive everything at a natural volume. In our test device, there is an acclimatization manager that helps us through the adjustment phase with very small volume adjustments. After a few weeks or months, we have then reached the calculated amplification level.
The Sound FS 1 R 312 gets its power from small disposable batteries that need to be replaced every few days. While this is not rocket science, it should be considered, especially for those with motor issues. A rechargeable battery would be much simpler to handle.
We had a carefree daily life in our test due to the IP-68 certification. This means that the hearing aid is particularly well protected against dust and water. We marched through the rain and then took out the hearing aids with wet hands - no problem at all. However, the water resistance really only applies to fresh, natural water and not to foamy bath water or salt water.
Rating Simplicity & security: 3,0
Extras
The finale belongs to the extras, meaning small additional functions that could give the hearing aid a few extra points: Do you suffer from tinnitus? Then you could use the optional tinnitus program in the Sound FS 1 R 312. Soft, gentle sounds are tailored to your hearing and engage all areas of the inner ear. It's nothing more than a distraction, and it works surprisingly well. The tinnitus fades into the general noise and no longer bothers you. It's a simple but effective tool that earns extra points from us.
We find the remote maintenance service exciting, which can be utilized. If you don't have the opportunity to go to the hearing care professional, you can contact them instead via the app, briefly describe your hearing problem, and then receive a data package with a new hearing aid configuration. If it sounds good, you upload it to your hearing aids.
Many hearing aids today come with a few health functions. However, since the Sound FS 1 R 312 does not have any specific sensors for that purpose, we cannot present any special features here. The functionality of the Sound FS 1 R 312 is limited to normal hearing, which is perfectly fine. Additional features like fall alerts or Siri integrations provide some added value, but they are not relevant for good hearing balance.
Rating Extras: 2,5

FAQ
### How big is the Sound FS 1 R 312 from Hansaton? Since a size in millimeters doesn't explain how large a hearing aid appears, we have divided the size perception into classes.

It could therefore be described as medium-sized. ### What is the price of the Hansaton Sound FS 1 R 312? The Sound FS 1 R 312 from the manufacturer Hansaton is currently offered by audiologists in Germany in a price range of approximately €1,300.00 to €2,000.00.
