Tempted to wear them outdoors too. Bought these for my husbands birthday since hes been working in wet, cold conditions and complaining about his other shoes hurting. Multiple rooms, literally all over my house never had a disconnect. 5mm jack (which is also shown on the Sennheiser site) It also shows you how to dial a call, answer phone, redial etc. I have warn these in my ears for over three months now and just ordered the gold set. Probably more sturdy choices out there so dont waste your money. I have 2 usb computer fans from them. Inso l. Like really gross. Overall extremely happy with the look and quality!
