They're good for connecting Internet radio to things like Bose Wave Radio and other audio devices to get stereo sound from different directions. This gives the effect of a live performance. This setup is way better than any system where the sound comes from a single point. It feels like quality headphones without the inconvenience of blocking out other noise and with something on your head or in your ears. I watch YouTube music videos on a laptop connected to a TV with an HDMI cable. The TV has an RCA audio output which I use to send audio from the TV to an old Bose Wave radio. The TV speakers still work because I'm not using the TV headphone jack which disables the TV speakers so the sound comes from both the TV and Bose which makes it sound great. When purchasing devices such as internet radios or televisions, check that they have an RCA output connector so that the speakers in the device are not turned off when you want to send audio to a different set of speakers. Many internet radios and televisions do not have a cinch output. When you plug a cable into the headphone jack to receive a signal, the speaker in the radio is disabled. You do not want that. Grace Digital Internet Radio has an RCA output. One of them is connected to the Bose Wave radio on one side and to the Grace digital internet radio on the other side. The stereo sound coming from left and right simultaneously is AWESOME! Of course, there are ways to wirelessly transmit audio signals between devices. But it can get quite complex and all parts of the system need to be able to do it.
