I be almost 71 year old and I be hear impaired from 40 year work in a power plant . I have use a pair of wireless headphone for the past several year that finally give up the ghost . I have spend the past year look for a replacement . none satisfy I because I want to be able to control the volume in each ear . even with in canal hearing aid , my left ear be worse than my right . I be not able to find anything until I run across the rs-140 . it have a balance control which allow I to `` balance '' the gain to each ear . I have read many of the report on this site which include some very negative comment . however , my experience have be nothing but good . no hiss , coverage throughout the house , no dropout spot . excellent sound , easy to understand what I hear from the tv . I subtract one star because they do have one fault . the volume control be on the backside of the earphone and when I attempt to lay my head on a pillow , it move the volume control . I have to be careful of this . I can also see where those who use outside the ear hearing aid will have a problem with the headphone push the ear against the hearing aid . other than that ... a very fine piece of gear ! I recommend they .
