The Amazon basics USB extension cable is a good quality unit and is priced well. We have several and they work great. If you have Amazon Prime its a steal:

Just make sure what ever headset you get is USB, having to deal with adapters can become a major pain in the ass - if they even work at all.

and a 10ft USB extension cord
I used the pogo with usb extender cable and love it. It's connected to the nexus 10 charger and it charges faster AND while screen is on.

Though that would work my extender is only 4'.
