can I connect / play my speaker to my TV HDMI or AUDIO port through the mini usb port?

Asked by: woodentop
Hi, Thank you for your question. No, the micro USB port is for charging the device only. However, you can use the analog input and connect a 3.5mm JACK cable to your TV.

Hi, is it posible that the Onyx Mini work as hands free in pc with windows 10? I can only use that hands free option with my android smartphone.

Asked by: JPCast
yes, you have to configure the listening settings for your cortana.... if its a laptop it may use lots of power. but should be just fine so long as your pc has bluetooth and you have it set as 2 connections
