Just a quick off-topic: just so you know, I'm 14 years old, so if Head-Fi didn't allow kids like me on here, lots (read: legions) of us wouldn't even be here in the first place, and Head-Fi might be a smaller community than it is right now. But then again, I have no idea.
Anyway, back on topic: I placed my Beats Pros round my dog's neck and played some solo piano for a while (note: my dog was lying on the bed so he didn't feel the weight). Turns out, he fell asleep after a couple songs. I think he liked it.
Mhm, I should try that sometime.. Although I think my dog is afraid of my headphone, heck, it's scared of anything.
