Quality audio equipment is rarely cheap, but did you ever stop to think about the environment? The Ashcraft Aria concept headphones are made from a combination of recycled materials and advanced audio technology designed for audiophiles. The headband is wrapped with wood recycled from acoustic guitars and the ear cups are made from reclaimed aluminum. The quilted leather surrounding the ear cups and lining are made from materials reclaimed from bags, jackets and other clothing. When it comes to sound, it comes from 40mm titanium-plated drivers that are tuned to offer some serious clarity. How often do you see eco-friendly headphones such as this?
