I do I have a Dual one from Walmart I got it in the automotive section. I am sorry it is in my vehichle so I can't give you the manufacturer. May I ask are you going to use it to travel? My mother-in-law warned me and it is true. If I use it in the vehicle you have to leave the windows rolled up the volume is very poor. Airplane forget it you have to read lips that is 2 different versions so maybe someone else has a version that is louder.
