It struck me the other day that people with hearing problems spend a fortune - £450 or more - for hearing aids, when their mobile phone has all the necessary gadgets for providing them with an aid to boosting volume; a microphone and Bluetooth. All that needs adding is a pair of Bluetooth earbuds for under £20.
There are even several Apps available on Google Play, but it's relatively simple to set up a hearing aid system yourself.
I tried one of the Apps but, for some reason, there was a noticeable delay. It must be a setting.
The advantage is that a set of Bluetooth earbuds are very inexpensive if lost. The disadvantages are the battery drain on the phone and Bluetooth earbuds need charging every 4 to 6 hours.
