These are used in our church for second language. It has no problem reach any place in the hall with clear voice. A couple of AA batteries last several months of Sunday use.

Good Quality

what is this device used for and is there anything else that goes with this device to make it operatable or is it just the earphone and sr-50 and you can hear whomever?
Asked by: Anonymous
The SR50 receiver is part of a complete Assistive Listening system. A wireless transmitter unit is required that will send signal to the SR50. Options available would be the portable PST-170 or the table top ST-300 transmitter unit. For a stand alone unit, the Williams Sound Pockettalker requires no additional hardware.

Does this device support stereo headphones or just single earphone? I understand that the audio would likely be mono but will the device drive mono audio to both earphones?
Asked by: Owfownugi
Yes, it drives mono audio to both earphones.
