Wonderful for the price

I love these little hearing aids. I have a little trouble inserting them because they're a different shape and slightly larger than my prior hearing aids... But I'm getting used to it. You truly cannot beat the sound quality for the price. I'm very happy so far.

Hi Tracey,

We truly appreciate your kind words! Thank you for sharing your experience with the fit. We understand they can feel a little different at first, but it’s wonderful to hear you’re already getting used to them. If you ever need any assistance, our customer service team is here to help!

Love the clarity

Love the clarity. I have the core ones. And upgraded to core one pro. The pull tab came off the right ear

Hi Joanne,

Thank you for your kind words, and we’re sorry about the thread that came off. We see that one of our agents is already assisting you, and we’ll let you continue the conversation with them until the issue is fully resolved. We appreciate your cooperation, patience, and continued support as we work to make this right.

The Core One Pro is even better than the CoreOne

The Core One Pro is even better than the CoreOne. The sound quality is amazing and the fit is so comfortable. My only criticism is that I have to put them in the case to change volume and program.

So far very pleased with them

So far very pleased with them. The only thing that I would enhance is Bluetooth or phone connection. The small tips could be smaller. Not worth returning.

Hi Janice,

We appreciate your kind words, and we hear you regarding Bluetooth. We are actually planning to incorporate Bluetooth soon, but it will be for controlling the settings through an application, not for streaming or taking calls. Still, thank you for your suggestion; we’ll pass it along to our team for future consideration. If you ever need any assistance, our customer service team is here to help!

To activate it:

Double-tap your hearing aid twice quickly to cycle through programs until masking starts.
Or long-press (3 seconds) the charging case button while the device is inside.

Core One Pro offers stronger sound output, 160% better noise reduction, and two additional sound modes — including wind noise management and tinnitus masking — all while staying just as discreet.
