Ordered last week, received within 2 days. Superb service by Headphone Zone. Used it twice since then. All you have to do is use a drop or two on one ear cushion, and keep it aside for like half an hour. The next thing you'll notice is that the leather feels fresh, smells nice and hopefully will help in increasing the life span of the cushions.
This is just super-awesome. The bottle looks much smaller than one expects by looking at the picture here, but then one does not need very much of the product. In my estimate, a bottle should be good for at least 15 applications to a pair of LCD size ear-pad. It comes with a couple of white application cloths and is very easy to use. I use my two LCDs quite reqularly and make it a point to apply the lotion after a fortnight of use. This is perhaps overkill, but I take very good care of my equipment and this is certainly worth it. I would not use generic leather lotions on my high-end equipment leather. Buy it if you love your expensive headphones!
This is a very nice product with are combination of beeswax, Carnuba wax, aloe vera and lanolin. I have spent lot of time searching for similar product but there seems to be none. It leaves a very nice shine. Quantity required is also minimal.
Headphonezone should keep this more in stock.
