Kim Kardashian Beats edition sells out in US, most countries

Update at 9:32am ET: Beats Fit Pro x Kim Kardashian are in stock at Amazon.

Apple's Beats by Dre division's latest Beats Fit Pro headphones are now sold out, or very close to selling out, worldwide. Designed in partnership with Kim Kardashian, the "Kim K" Beats Fit Pro came in the three muted, earthy colors, Moon, Dune, and Earth.

At time of writing, none of these color options remain available to buy from the US online Apple Store. The Earth color is still listed on the UK and French stores, while all three appear to remain on both the German and Japan stores.

It's possible that some US stores will have stock on-hand. Officially Apple is saying that in-store pickup is no longer available.

Prior to release, Kardashian said that she had an artist paint Beats Fit Pro models in these neutral tones, before taking the idea to the company.

"I wanted to break away from the idea that headphones have to be colorful to make a statement," said Kim Kardashian at the time. "This collaboration is special because it allows you to blend in or stand out, and Beats is known for creating products that showcase individuality."
