Choosing hearing aids involves more than comparing specifications. You want to know how they fit into your day: making adjustments during a conversation, taking a phone call, wearing them with glasses, and keeping them charged.
Didasou S2 brings together a lightweight receiver-in-canal design, physical buttons, app adjustments, and Bluetooth audio. This Didasou S2 hearing aids review explains those features and the practical considerations that can help you decide whether S2 suits your routine.
This overview is written by Didasou and covers our product’s features and intended use.
1. Who Is Didasou S2 For?
Didasou S2 is an OTC hearing aid for adults aged 18 and older with perceived mild to moderate hearing loss.
It may appeal to people who want everyday hearing support with the flexibility to make quick adjustments on the device or personalize settings from a phone.
Before choosing, consider your preferences:
-
Do you feel comfortable wearing a hearing aid behind your ear?
-
Would you use Bluetooth for calls, music, or videos?
-
Do you want physical controls alongside an app?
-
Are you comfortable handling small ear domes and keeping them clean?
Your answers matter as much as the feature list. A hearing aid should suit both your listening needs and the way you prefer to use technology.
2. Design and Fit: A Lightweight RIC Style
S2 uses a receiver-in-canal, or RIC, design. The main body rests behind the ear, while a thin wire connects it to a small receiver and ear dome inside the ear canal. Each hearing aid weighs approximately 3.5 grams.
This arrangement gives you two areas to assess when trying it: how the body sits behind your ear and how the dome feels inside your ear canal.
If you wear glasses, try S2 with your usual frames. Check whether both sit comfortably, and practice putting on and removing your glasses without catching the receiver wire.
The right dome fit also deserves attention. During your trial, notice whether the dome stays secure when you talk or move your head, and whether you feel pressure after wearing it for a while.
3. Physical Buttons and App Controls: Two Ways to Adjust
S2 offers 11 volume levels and three listening modes, with adjustments available through its physical buttons and free companion app.
Quick Adjustments on the Hearing Aids
Physical buttons let you change volume and switch modes without reaching for your phone.
That is useful when you want to make a small adjustment and return your attention to the conversation. You can also choose to use the buttons for most daily changes and open the app only when you want additional control.
More Personalization From Your Phone
The app adds separate left and right adjustments, bass, mid, and treble settings, plus noise reduction and feedback suppression controls.
When exploring these settings, change one thing at a time. Compare the result in a familiar setting before making another adjustment. This makes it easier to identify which changes you prefer.
For someone who wants a choice between simple controls and more detailed adjustments, this flexibility is a key reason to consider S2.
4. Listening Modes for Different Environments
S2 includes Quiet, Noise, and Outdoor modes, alongside DSP sound processing and feedback suppression.
Treat the modes as options to explore in your own surroundings. A setting you prefer at home may feel different during a meal with friends or a walk outside.
When comparing modes, pay attention to more than loudness:
-
Can you comfortably follow the person you are listening to?
-
Do surrounding sounds feel balanced?
-
Does the setting remain comfortable over time?
Noise reduction does not remove every background sound. Fit, settings, and the listening environment all remain part of the experience.
5. Bluetooth Calls, Music, and Videos
S2 supports Bluetooth calls and audio streaming from a compatible phone.
The practical value depends on how you use your phone. If your day includes calls, podcasts, or short videos, streaming through the hearing aids you already wear may be a useful convenience.
Before purchasing, confirm compatibility with your phone. During setup, test a call and your usual audio apps so you become familiar with the connection and controls.
Bluetooth may be an important part of your decision, but also consider how much you value the hearing aid’s fit and everyday adjustments.
6. Battery Life and the Charging Case
S2 offers up to 24 hours per charge and up to 96 hours total with the charging case. Charging takes approximately two hours. Actual battery life varies with use, settings, and environmental conditions.
Think about charging as part of your routine: where the case will sit, when you will return the hearing aids to it, and whether you will remember to recharge the case before travel.
The case includes a silicone base and silicone lining inside the lid. These details are worth considering alongside battery capacity, especially if you regularly handle the case on a bedside table or desk.
7. Daily Care Is Part of Ownership
A useful review should also consider what happens after setup.
S2 needs regular cleaning of its ear domes, microphone openings, and charging contacts, along with wax guard replacement. The hearing aids should be dry before charging.
Make sure you are comfortable handling these small parts. A consistent place for cleaning tools and replacement accessories can make the routine easier to maintain.

8. What to Evaluate During Your Trial
S2 includes a 60-day trial from delivery and a 12-month limited warranty, subject to the applicable policies.
Use the trial to assess the situations that matter to you. Try familiar conversations, your usual glasses, phone calls, and your daily charging routine.
Keep a short note of what feels comfortable and where you need help. Specific questions—such as a dome feeling loose or difficulty connecting your phone—give the support team a clearer starting point.
Read the return policy before ordering so you understand the terms.
Is Didasou S2 Right for You?
S2 is worth considering if you want a lightweight RIC hearing aid with physical buttons, optional app personalization, Bluetooth audio, and rechargeable use.
The deciding question is how well those features suit your daily life. Consider the fit you prefer, the controls you will actually use, and the maintenance routine you can comfortably follow.
