A:AnswerMy headsets have red and blue blinking lights when they are looking for the blue tooth connection. When I turn on the blue tooth adapter that I purchased for the TV it connects and the blinking goes away.
A:AnswerNo 3.5 mm jack on the BT uproar - Bluetooth only unless you go for the wired only version. You have to go a step up with the Hesh 2 for both BT and wired capabilities, but the hesh 2 are a bit larger. If you like the size of the uproar but need both BT and wired, I’d look at the JBL e45bt which are both BT and wired capable.
A:AnswerI have both the Uproar and Hesh 2, and they seem to play nice with all levels of USB power providers. Give them 2 amps they will charge very quickly, give them 500 mA they will still charge but just take longer. They are not heavy power users in any case; on a standard 500 mA USB outlet my Uproar goes from dead to full charge in about half an hour.
