CrystalTone

The powerful CrystalTone amplified phone not only increases the volume up to 35dB (one of the more powerful amplifiers available!) it actually enhances the sound quality for crystal clear reception.Other amplified phones enhance the sound quality in only one of two ways: either by amplifying only high-frequency sounds or by amplifying either the high or the low frequency sounds. The CrystalTone is the only amplified phone available that gives you BOTH options in one phone. Its unique CrystalTone (A/B) switch lets the user try both methods, instead of limiting the user to one or the other. This gives the CrystalTone greater flexibility to meet a wider variety of people's hearing needs.
