Apple has joined with French fashion house Balmain on special editions of its Beats Studio Wireless and Powerbeats3 headphones, echoing marketing tactics adopted with some other Apple wearables, like the Apple Watch.

In both cases the headphones use a unique "Safari" color with metallic gold accents, and conspicuous Balmain branding. For carrying them around, buyers get a matching suede case featuring a Balmain plaque and a coin zipper.

To sell them the two companies have employed model Kylie Jenner, who is appearing in photos and video, including a post on her Instagram feed.

The Balmain Studio Wireless headphones cost $599.95, well above the standard $379.95. That amount is however as much as Alexander Wang's "Dove Gray" color.

The gap is much smaller with the Powerbeats3, as the Balmain version is $249.95 versus the regular product's $199.95.
