I live in a duplex with thin walls. I also wear hearing aids when I'm around others but prefer not to when I am alone. I bought these headphones so I could have my television turned up loud enough for me to hear it without disturbing my neighbor and they work great! With these cordless headphones, I can walk the length of my home without missing a word of whatever program is on. I can go out to the garage or, even further, to the mailbox, and still hear just fine. I also plug these into my music player and listen while I clean the house or work on projects. I love these headphones. They have truly changed my life. Before I had these, I never listened to music because I had to have it turned up so loud it was crazy, or I had to find some way to be connected to my player with a wired headset and all those dangling wired got in my way when I was working on various projects. This headset is really the best for me. Sound Quality I am not an expert on sound quality as I have had hearing aids for years and years, but for me, I am very satisfied with what I hear with these headphones. Comfort Sometimes I forget I have them on. Design I can wear these with my hearing aids without getting feedback.
