I bought this to try with my headphone jack with my ROKU remote. It worked. Lets me have personal sound close by without using ear nubs, so I can walk freely away and back. Without having louder TV speakers disturbing the family. My only complaint is, I wish both cords were at least a foot longer each. But I found one longer cord in my own speaker cord collection, long enough that if I pick up the ROKU Device to change apps, it wont drag the speaker with.
