  2. Compact Size: MEMS speakers are exceptionally small, allowing for a sleek and discreet design in OTC hearing aids. This miniaturization contributes to the earbuds’ unassuming appearance.
  3. Customization: The tiny size of MEMS speakers permits precise audio customization. Users can fine-tune their listening experience to meet their specific needs.

A Dual-Purpose Marvel

What makes the Liner Deluxe stand out is its dual identity. First and foremost, it’s designed as an over-the-counter (OTC) hearing aid. Secondly, it moonlights as a pair of Bluetooth earbuds. Traditional hearing aids lack the flexibility of streaming audio via Bluetooth, which is where the Liner Deluxe steps in.

What’s truly remarkable is how these earbuds are discreetly designed. They look like your standard true wireless earbuds, effectively eliminating the stigma associated with wearing a hearing aid.

Now, let’s dive into the details.

The Design and Unboxing Experience

The Liner Deluxe comes neatly packed in a standard true wireless earbud case. This case is equipped with wireless charging capabilities, adding convenience to your life. Plus, it features a built-in UVC sterilizer, a feature not commonly found in earbuds. This nifty addition ensures your earbuds are sanitized with every use, promoting hygiene.

The earbuds themselves sport a sleek design, complete with color-coding: blue for the left and red for the right earbud. They even come with ear hooks for a secure fit.

The design of these OTC hearing aids is a nod to modernity. They resemble standard true wireless earbuds, featuring a charging case with wireless charging capabilities. Additionally, some models come equipped with UVC sterilizers in their cases, promoting hygiene and safety, especially crucial in today’s world.

Enhanced Hearing Aid Mode

The primary function of the Liner Deluxe is to serve as a hearing aid. When no media is playing, you can pop these earbuds in, and they act like a high-powered transparency mode. The earbuds’ microphones are exceptionally sensitive, granting users the ability to hear sounds they may have never heard before.

In their primary role as hearing aids, these devices offer an exceptional “enhanced hearing aid mode.” When no media is playing, users can wear them to access a heightened “transparency mode.” The microphones on these earbuds are highly sensitive, allowing users to hear sounds and conversations they may have previously missed. For individuals with hearing impairments, this can be a profound and life-changing experience.

Customizable Hearing Experience

The Liner app complements the earbuds, offering additional controls and customization. You can adjust the tone of the earbuds, fine-tuning your listening experience. The app also lets you choose various environmental modes, catering to different scenarios, such as dialogue mode, restaurant mode, commute mode, and normal mode.

One feature I hope to see in the future is automatic mode detection. It could be cumbersome for elderly users to constantly switch modes based on their surroundings.

Battery Life and IPX5 Rating

In hearing aid mode, the Liner Deluxe provides about seven hours of battery life, with the case extending that to 21 hours. When using them in Bluetooth mode, you can expect around nine hours of playback time, with a total of 27 hours when including the case. Charging the earbuds takes approximately one to one and a half hours.

These earbuds also boast an IPX5 water resistance rating, making them suitable for daily use. The battery life of OTC hearing aids with MEMS speakers is impressive, lasting several hours in hearing aid mode and even longer in Bluetooth earbud mode. Some models are equipped with IPX5 water resistance, ensuring they can withstand daily activities without issue.

Customized Audio Experience

As for the audio quality, the Liner Deluxe doesn’t disappoint. While it’s not designed for audiophiles, it delivers good bass performance and clear mids. Highs are decent, ensuring that instruments don’t sound muffled.

In summary, these earbuds strike an excellent balance between serving as hearing aids and Bluetooth earbuds. They’re FDA-approved for over-the-counter hearing aid use, and their IPX5 rating and sensitive microphones make them ideal for daily life.

So, if you’re in the target market for this unique product, it’s definitely worth considering.
