We're huge fans of Freitag here at Grafik – its stylish bags, accessories and clothing made from recycled materials not only look great but are great for the planet too.
Freitag's latest release is the result of an inspired collaboration with Sennheiser – headphones incorporating a colourful piece of truck tarp which come with their own matching Freitag case. Each set is unique, and the headphones are available in a worldwide limited edition of just 1500.
The headphones retail at £150, and we have one pair to give away to a lucky Grafik reader. To be in with a chance of winning, send an email with 'Sennheiser' in the subject box to email@example.com, telling us the model number of the headphones (clue: it begins with ‘F’ and you can find the answer here). Deadline is Friday 29 April.
If you can't wait, a limited number of headphones will be available to buy online at freitag.ch from Friday 15 April 2016.
