But there's a problem that all cordless phones share, no matter what frequency they use: low volume. I'm not hard of hearing, but I often have difficulty understanding a caller. I don't have a low-volume problem with corded phones, especially the old Bell Labs rotary phones, which were designed and tested by the world's greatest acoustic experts.
I went to Fry's on Friday to pick up some blank DVD's and I ended up walking down the phone aisle, just to see what they were selling. One phone immediately stood out, because it was white and had a big red light on it: the Uniden EZI996 900 MHz Cordless Phone. It's designed for the visually or hearing impaired. It cost $40. It has a volume boost switch on the handset, as well as an adjustable volume control. I bought it.
It's the best cordless phone I've ever used. You can crank the volume way up. The sound quality is great. I also like the fact that it's white and has the blinking red light, because it's easy to find when it's ringing. The display is large-type, which is useful whether or not your vision is impaired.
All phones should be so well designed.
