MAKING OUR PRODUCTS LAST LONGER We want everything we make to last longer. This means taking responsibility for our products throughout their lifecycle, improving features that will help prolong their lifespan, as well as using safer and more responsible materials in both product and packaging design. Our efforts in this field are ongoing, but below are some examples of improvements we’re making. Longer lifespan: We want you to enjoy your Marshall product for years to come, so we build our headphones and speakers to be rugged enough to withstand every- day wear and tear. We also design them with new features in mind so that you can get more out of them for longer. For example, our products are ready for next-generation Bluetooth LE Audio technology including AuracastTM, and you can download OTA updates so that your product has the latest software. We also now offer authorised repair services (1) and spare parts for Emberton III through our website. Materials: When switching to more responsible materials, we focus on recycled sources and better chemicals. 79% of the plastic in Emberton III comes from recycled plastic (2) made from preloved products including used electronic devices and CDs. Emberton III is also entirely PVC-free because of PVC being considered one of the most harmful plastics. Packaging: Our packaging is designed to minimise its environmental impact. To do this, it’s been optimised for transportation, we've minimised the plastic content and used materials from responsible sources. Emberton III’s packaging is 96 % paper-based with a recycled content of 77 % (3). We also use vegetable oil-based inks made from soybeans instead of traditional petroleum oil-based inks.
