Purchased some of these just last week. Waiting for them to arrive, will not be going clubbing/doofing again without them as per Mitch's recommendation. This is something I've been meaning to do for a long time, I've been going out to clubs and doofs for about 8 years, exposing my ears to sounds loud enough for my body to vibrate to, it's time I look after them so I can continue doing so for a long time.
