First let me say that I am happy that the spare ear cushions for my HD650 are for sale. The old ones deteriorated by not using them for a few years. Same as the headband cushion, by the way. I have been waiting months before they became available, since both parts were sold out. I have the ear cushions, but I’m still waiting for the headband cushion to become available. The website says that the part is sold out, but usually it takes just a few days before the item is available. Having waited for months, I can say this is just not true. I’m not happy with the replenishment rate, which is a matter of anticipation on the procurement department. It is not that hard. And it would be nice to have an expected availability date on the website, if it isn’t so, that it takes just a few days. I give one star, so that my review is being read and action is taken. For the product, packaging, e-mails etc. it’s a 5-star.
