The Audio Service G5 16 Sina in review
Hier haben wir es mit einem Auslaufmodell zu tun. Es gibt bereits neuere Varianten dieses Herstellers und natürlich auch von anderen Herstellern. Die Gesamtnote wurde mit einem Abschlag versehen.
Here we take a look at a hearing aid of the highest quality level that is worn in the ear. It is called G5 16 Sina and comes from the manufacturer Audio Service. It can be used by all people with mild to moderate hearing loss who desire a hearing aid of very small size. Due to its natural, cleverly chosen fit directly in the ear canal, it has very good sound properties.
Hearing comfort
The comfort features determine how pleasant everyday hearing is perceived. In this hearing aid, the manufacturer provides customers with comprehensive noise management. A classic noise suppression aims to reduce annoying background noises to a bearable level. The noise suppression in the G5 16 Sina is solid. There are hearing aids with significantly more effective noise reduction, but this one should be sufficient for normal demands. This model can do without wind noise management. The hearing aid sits deep enough in the ear canal that wind noises don’t become a problem at all.
The impulse filter in this hearing aid is quite solid and suitable for everyday use. Hearing aids like the G5 16 Sina maintain the natural spatial perception that we have experienced since childhood. The function of the outer ear, head size, head shadow effects – all these parameters create a genuine, authentic 3D hearing experience. Very important for good speech-to-noise distinction is the number of frequency bands. With 20, this hearing aid is among the best and offers excellent adjustment options.
Other hearing aids already use artificial intelligence in their signal processing, but the G5 16 Sina does not yet incorporate this strategy.
Rating Hearing comfort: 2,3

Operation & connectivity
The operational options for hearing aids today are as simple or as complex as anyone would like. The basic functions operate fully automatically, of course. We wanted to know how users can additionally access the G5 16 Sina. The simplest control option is always a button directly on the hearing aid, and this one has it. It can be programmed according to your wishes. Do you want a manual volume control? No problem, the button allows for stepwise adjustment of the volume. Or do you need different special programs for your daily work or hobbies? These can also be activated via the button. If you prefer to keep everything in automatic mode, you can simply ignore the button or even have it deactivated. We do like those small remote controls, and for this model, we found one. This allows for discreet small adjustments to the volume or sound.
The modern form of control via voice command is not yet found in the G5 16 Sina. Besides buttons or remote controls, some hearing aids also have tap control. This means you can simply tap your ear briefly, and then the device switches. However, we don't have that here at Audio Service; it would have required specific sensors.
If you like, you can download an app. This provides a convenient and discreet way to change the volume or hearing programs on the G5 16 Sina. Everything works quite well. Unfortunately, we have to forgo a streaming function here and continue holding the smartphone to the ear as usual.

Simplicity & security
We are also interested in how quickly one adapts to the G5 16 Sina and how easy daily usage is. The automatic situational recognition plays a significant role in our test. The better it functions, the easier our hearing goes through the day. The G5 16 Sina operates confidently here and adapts to many situations. We are very pleased with the integrated acclimatization manager. It gradually increases the volume of the hearing aid in tiny steps until our target amplification is eventually reached. We can relax and gradually become accustomed to the new hearing impressions.
The G5 16 Sina is not equipped with a rechargeable battery, so it is not rechargeable. The power supply is provided by a hearing aid battery size 10. It needs to be replaced every few days.
With IP 68 certification, the hearing aid can withstand various adverse influences. Dust cannot penetrate, it can endure prolonged immersion in water, and it is also protected against touch.
Rating Simplicity & security: 2,0
Extras
Everyone appreciates a few extra features, so let's see if we can find something here: We noticed the tinnitus option. Those who wish can set up a special tinnitus program. This gently plays soft noise in the ears, providing some distraction from the annoying tinnitus. The sounds can be customized according to personal hearing preferences.
Unfortunately, there is no option for remote adjustment. Therefore, anyone who needs optimization and wants to change their hearing aid settings will have to visit a hearing professional.
A new trend in the hearing aid industry is integrated sensors that can track some personal health data, for example. However, the G5 16 Sina does not offer this. The functionality of the G5 16 Sina is limited to normal hearing, which is perfectly fine. Additional features such as fall alarms or Siri connections provide a substantial added value but are not relevant for good hearing balance.
Rating Extras: 3,3
Conclusion: Audio Service G5 16 Sina
This test device ranks in the lower positions of the overall results and is missing some features. We give it a score of 4.08. This is acceptable for less demanding listeners, but for a very active lifestyle, we recommend a hearing aid with more extensive comfort features.
