I absolutely love kink.com content, but something I've always had a problem with is the sound quality.
It's often really difficult to hear what everyone is saying - you might hear the sub loud and clear, but not be able to hear the what the dom is saying.
This is especially a problem on HogTied/DeviceBondage where there is usually more distance between the models. In those cases, a mic pack could be given to the dominant which would help no end!
Oh, and I have absolutely no clue how this ended up in the Kink University section. If someone could move it that would be great...
