Phone amplifier makes phone useable in noisy environment
Have been trying to use a new phone system in a noisey industrial environment and the volume level wasn't cutting it. I found the HA40 product, it was hoped that it might enable us to use the phones like anywhere else. And after 2 weeks use, I can say it works great! Callers voices are loud and clear at low boost settings (2/4 bars)! I think we need to order some more of these. Works very well for us. Running off original 9V battery - would be nice to have a wall-wart option to avoid the need for batteries. Thank you.
