HearAll Bluetooth Phone Amplifier

If hearing loss has made cell-phone calls frustrating, the SA-40 HearAll Bluetooth Phone Amplifier gives you back the conversation. It pairs with virtually any smartphone over Bluetooth and boosts incoming call volume by up to 40 dB — far beyond what your phone's own speaker can deliver — so voices come through loud, full, and clear. A 3-position tone switch lets you shape the sound to match your hearing, whether you need more bass, a balanced range, or lifted highs. And if you wear T-coil hearing aids, flip the SA-40 to T-Coil mode: the caller's voice goes straight into your hearing aid with no static and no sound played aloud — completely private, completely clear. Freedom matters. With a 33-foot wireless range, you can set your phone down and move around the room. A full charge over USB-C delivers up to 10 hours of talk time and up to 14 days on standby. At just ~3 oz, it clips to a visor, belt, or pocket — or tucks in a purse. The SA-40 is the handset you didn't know your cell phone was missing.
