Earphone for all


We launched a campaign to create the first high-end stereo earphone designed for you — whether you are a user of hearing aids, cochlear implants, or none of them.

Adapt to All Conditions

Hai is compatible with all hearing aids and cochlear implants with T-mode. It can receive audio from all Bluetooth sources and send it to your device.

Adapt to All Conditions

Hai is compatible with all hearing aids and cochlear implants with T-mode. It can receive audio from all Bluetooth sources and send it to your device.

Born for Flexible Use

Now you can switch between Hai's earbuds and neckcoils to match the aids and ears! Hai beats most of the streamers by providing stereo sound to single-sided users or users of two different brands.

Create Superior Sound Quality

Most streamers don’t allow their users to enjoy stereo sound with single-sided aids or aids by different brands. We advanced telecoil, an established and versatile technology, to provide outstanding sound quality for diverse aid usage scenarios.

How to use


As Simple as a Streamer, But Beyond a Streamer

1. Connect

Connect your Hai to any of your Bluetooth audio sources (e.g. mobile phone, Bluetooth adapter of your Switch player).

step2

2. Turning on T-mode

Turn on the T-mode of your aids. Hai's DBC technology will clear the buzzing sound of the T-mode.

step3

3. Enjoy and be fashionable

Hai's neckcoil sends a high-quality audio signal to your hearing aids and/or cochlear implants. All while looking good!

* Switch made easy

✅ If you use a single hearing aid, attach one Hai earbud for your hearing side, and use telecoil for the side with hearing aid.
✅ If you want to use Hai without hearing aids and/or implants, just plug in two earbuds and modify the sound with our app.

We provide even more!

Stop The Buzz

Please check our price list and support us on our Indiegogo campaign!
Please support our Indiegogo campaign! If the campaign goes a success, the estimated delivery is in early March 2021.
Indiegogo is a launchpad for entrepreneurial ideas. It's a platform for individuals and startups to raise funds with a crowdfunding campaign. It allows you to support the ideas you admire and get the rewards if the campaign successfully reaches the fundraising goal. We use it to acquire the starter capital required to ensure that the Hai device can be produced. If we succeed, we will ship the reward you choose (e.g. a Hai Kit!) to you! For more info, please check out this article, Learn About Crowdfunding & How Indiegogo Works, written by Indiegogo.
Sure thing! You can pick up hand-free calls and enjoy the clear tone provided by Rearia Hai.
The streamers produced by the hearing aid/cochlear implant brands (e.g. Phonak Compilot) use customized digital signal to transmit audio to their devices only. For those who wear different brands, which are not in business alliance, HA/CI on each side, they cannot listen to music for both ears. Those streamers also fail to satisfy the need of single-sided HA/CI users. For more comparison between Hai and the other products please check this article, What makes Hai stand out for hearing aid & implant users.
Indeed, some hearing aids are coming with built-in Bluetooth; however, for those who wear different brands, which are not in the same business alliance, HA/CI on each side, they cannot listen to music for both ears. Those hearing aids also fail to satisfy the need of single-sided HA/CI users. Addtionally, most of the hearing aids with Bluetooth can only connect to iOS, which means the users are not able to connect them to their laptops, tablets, and even their players such as Swithc. For more comparison between Hai and the other products please check this article, What makes Hai stand out for hearing aid & implant users.
