Erin was totally begging for this surprise. Back before February of 2011, she would always talk about how her office at Cal Poly was so distracting. Not because her office-mates are annoying, but because the walls are paper-thin. So a casual conversation next door made it really hard for her to focus, and we all know how much focus you need to do hardcore maths. She also told me she liked my headphones, and we had recently discovered thesixtyone.com.
Talk about waiting for the right moment 
. I got her some similar ones to mine. I had them shipped to me, and then hid the package in her office desk drawer. Now that she has them, she hardly goes a day without using them.
Probably the thing she likes the most (aside from their relatively good quality) is the ten-foot cord. She can use them during any activity she wants, because she can walk quite far and doesn’t have to hold anything. That includes moving around her office while she works, cooking and cleaning, and of course karate-karaoke. And as far as I know, Erin holds the only black-belt in karate-karaoke. All in all, a worthwhile surprise.
Bow in respect to Sensei Erin.
Addendum: http://www.karatekaraoke.com/. But they obviously got the idea from Erin.
