I think when you first plug it in it defaults to 16 bit 48KHz. The back of these shoe?s are low enough (a little over one inch from cushion to top), to make them easy?on?s and easy-off?s, but high enough that I don?t sound like a galloping horse when I walk around in them. Thought these were going to be as comfortable, but they aren?t. With this oil I just put a drop on a comb and comb it in, I start with a comb so it goes deeper than just the surface hairs. Sound seems pretty balanced. I use them at the gym regularly and am amazed how long the batteries last. After properly installing them, it was very clear that they weren?t actually anchored to the wall. They stay connected pretty well, occasionally they?ll drop if you haven?t been playing anything for a while. I can wear them, but even the large barely fit. This wouldnt be such an issue if it wasnt the ONLY way to switch thru the equalizer settings.
