Query: The interference is unbearable.

These headphones (AW791) were a gift and look very nice. The design did not bother me as it did other reviewers. I found the headset quite comfortable. However, the sweaking, hiss, interference, and occasional loss of signal are unbearable. I tend to listen to music at a louder volume, but regardless, the clicks and hiss are present at all volumes. I am not an audiophile. But the sound quality is unacceptable. I am not familiar with any other wireless headphones to make a comparison, but these are terrible. Note: I live in an apartment building. Perhaps it would work better in a single-family household with less 900 MHz interference. BEWARE.
