Grado has a new pair of their signature headphones on the way, and between the pricing, hemp-infused wooden body and pot leaf insignia, it’s clear they’ve got their eye on a very particular customer.

The Brooklyn-based audio brand known for their rich, open-air sound has a pretty established lineup at this point but over the past few years they’ve been playing around more with limited editions that use different types of wood and composites to house their audio components. The Hemp Headphone’s swirly, psychedelic body is a composite of maple wood and “highly compressed hemp,” the company says.
