Hi all, just wondering a couple things. First of all, trying to buy a pair of bone induction headphones. Secondly, debating on which is better, bluetooth or wired for the use with Blindsquare. According to the manual, the user should have wired headphones, but I'm being told bluetooth wireless ones are better. I found a pair of wired ones I liked for $43 on Amazon, but not sure if those versus the bluetooth ones will work better. HElp!
