A:AnswerThe Sennheiser HD-1 in ear headphones are NOT weatherproof or waterproof.The band that goes around the neck is covered with real leather that would be ruined if it got wet so they are no good for the gym or in the rain but they sound great.
A:AnswerYes, Sennheiser say they will pair up to eight different devices. I use them for two phones. I dont get the disconnect like I do with my other sets. You have to reconnect the second device the first device should reconnect.
