A:AnswerYes, you can wear these headphones while running or walking both indoors (on a treadmill) or outdoors (on a track or walking/hiking path). They seem to hold up well against sweat. However, I would not recommend wearing them in a rainstorm.
A:AnswerHi, Magdelene! The headset contains a built-in lithium-ion rechargeable battery. You'll need to use the supplied USB Type-C cable for charging. Please refer to this link for more information:

A:AnswerIf your RCA LED/LCD HDTV has blue tooth built in, you can easily connect it wireless. If not, you can buy and attach a simple audio/blue tooth dongle to your TV. Best Buy sells those as well. These are good headphones.
