What is Didasou S2?

What is an OTC hearing aid?

An OTC (Over-the-Counter) hearing aid is a hearing device designed for adults 18 and older with perceived mild to moderate hearing difficulty.

OTC hearing aids can be purchased directly without a prescription, making hearing support more accessible and convenient for many adults.

Is Didasou S2 a hearing aid or a hearing amplifier?

Didasou S2 is an OTC hearing aid, not a simple sound amplifier.

Sound amplifiers only make sounds louder, while hearing aids use digital sound processing to provide a more personalized listening experience based on different listening environments.

Is Didasou S2 FDA registered?

Yes. Didasou S2 is FDA registered as an OTC hearing aid and designed to meet applicable FDA requirements for this device category.

Who is Didasou S2 designed for?

Didasou S2 is designed for adults 18+ who experience perceived mild to moderate hearing difficulty and want everyday hearing support.

It may be suitable for people who want help with situations such as conversations, watching TV, phone calls, and social activities.

How do I know if an OTC hearing aid may be right for me?

You may consider exploring an OTC hearing aid if you often:

· Ask people to repeat themselves 

· Turn up the TV volume higher than others prefer 

· Have difficulty following conversations in restaurants or group settings 

· Feel that speech sounds less clear than before 

· Feel that listening requires more effort 

If you are unsure, a hearing check can help you better understand your hearing needs.

Who should not use an OTC hearing aid?

OTC hearing aids are intended for adults 18 and older.

You should seek medical advice before using a hearing aid if you experience sudden hearing changes, severe hearing difficulty, ear pain, drainage, dizziness, or other unusual ear symptoms.

Will it be hard to get used to Didasou S2?

Not really. Like any hearing aid, Didasou S2 takes some time to adjust to.

Many users adapt by starting with a few hours of wear each day and gradually increasing usage as they become familiar with new sounds.

The Didasou app makes the adjustment process easier with adjustable volume, multiple listening modes, and personalized bass, mid, and treble settings.

Will Didasou S2 feel uncomfortable or be noticeable?

Didasou S2 is designed for comfortable and discreet everyday wear.

Each hearing aid weighs only 3.5g and uses a slim RIC (Receiver-in-Canal) design that sits comfortably behind the ear for lightweight daily use.

Does Mini require an app?

No. Mini is adjusted directly on the hearing aids and does not require a smartphone app for everyday use.

How do I adjust Mini?

Use the physical button to adjust volume and switch between Quiet, Noise, and Outdoor modes. Mini offers 9 volume levels. Follow the user guide for the button sequence.

Does Mini remember my settings?

Yes. Mini saves the last-used volume and listening mode for the next time you turn the hearing aids on.

What does the lanyard attach to?

The detachable lanyard attaches to the Didasou Mini charging case, not to the in-ear hearing aids.

Does the case actively dry the hearing aids?

No. Didasou Mini uses a passive desiccant sheet to help keep the hearing aids dry during storage. It is not an electronic dryer or heater.

Who are Didasou OTC hearing aids designed for?

Didasou OTC hearing aids are designed for adults with mild to moderate hearing loss. If you have severe hearing loss, we recommend consulting a hearing care professional.
