Hearing aids, honestly priced.
All three are real OTC hearing aids, all rechargeable, and all thousands less than a pair from an audiologist. Two sit hidden in the ear, set with one button or from your phone. The third puts phone calls and music in both ears.
Certus One
One button, no app, nothing to pair. Charge the case overnight, put them in with your morning coffee, and hear everyone at the table.
Best for: anyone who wants to hear clearly without using a phone. The pair a son or daughter buys for Mom or Dad.
Certus Pro
A five-minute hearing check tunes each ear on its own, so the weaker ear gets more help. Four listening modes match the sound to the room, and you change the volume from your phone.
Best for: one ear worse than the other, a busy social life, or anyone who would rather change the volume from their phone than touch their ear. Calls stay on your phone.
Certus Max
Phone calls, video calls and music play in both ears over Bluetooth, on iPhone and Android. A touchscreen on the case shows both volumes. It sits behind the ear, so it fits small ear canals.
Best for: anyone who dreads phone calls, wants music and audiobooks in both ears, or has ear canals too small for in-ear hearing aids. Works with iPhone and Android.
