To hear your best with a common age-related hearing loss, it is important that hearing aids provide adequate high-frequency (high tone) amplification. Emphasizing the high frequencies can alter the sound quality substantially, leading to a less natural sound on first impression. But ultimately, replacing those missing high frequency sounds (that haven't been heard clearly for some time) is the key to understanding speech better.
So while you're listening to our sound samples, remember that what sounds best from a sound quality perspective may not align with what provides the greatest benefit to speech clarity. If you're an experienced hearing aid user, you will know well that hearing aids can seem unnatural and overly bright initially, but over time you acclimatize and retrain your brain to hear in a more natural way.
We also encourage you to go beyond the sound samples and click through our ratings for speech performance in quiet and noisy settings, own voice quality, feedback handling, and audio streaming quality.
