I bought this device because it allows you to use any headphones you already have. I use it to listen to some TV shows without making them so loud that my wife has to wear headphones. I feed it from my HiFi amp connected to the TV. It works very well and gives me independent volume control. With open headphones or simple in-ear headphones, the latency is very low. So make sure your headphones/earphones fit snugly so there is no sound from the TV, otherwise the delay will be unacceptable. Of course, this is not a problem if you only listen through this device. The sound quality is excellent and the bass is very good when using high-quality headphones. Since my hearing isn't that bad (yet), I don't have to fiddle with different sound enhancement modes for hearing impairments. I find that when using in-ear headphones the footprint of the receiver and headphones is very small compared to some other solutions which are large cans with receivers built in. Too bad you have to use that, but at least you don't look like an idiot. (Well, less of an idiot.)
