Has anyone come across a bluetooth amplified ringer which would make it easier to hear incoming calls from a mobile phone in a noisy workshop.
I don't want to play music or answer calls with it like a bluetooth speaker, just a loud call tone.
There are plenty of wired ones for land lines, like this Compact Loud External Phone Ringer but I can't find a bluetooth one.

A bluetooth speaker would be ok, as long as you can answer the call on your mobile handset without it transmitting the call through the speaker.

Cheers, Murray
