House of Marley designed the dark grey pods, which don't use any virgin plastic, as "an eco-conscious alternative within the plastic-driven market".

The earphones themselves are made from recycled plastic and polylactide. Also called polylactic acid (PLA), this is a bioplastic typically made from fermented plant starches found in corn or sugarcane. The material is also used in a pair of headphones by Aivan. Recycled silicone is used for the ear cushions on Liberate Air to provide comfort inside the ear. House of Marley designed the material, which it calls Regrind, from disposed silicone sourced from either after processing, or being thrown away.

The buds are housed in a case made with a composite of recycled polypropele, a type of plastic, and sawdust fibres. Aluminium is used for the case hinge and clasp, and also on the nozzles on the earbuds.
Also fatured on the case is a fabric designed in-house by the electronics brand, called Rewind. The textile is a blend of 40 per cent recycled polyethylene terephthalate (PET), 30 per cent reclaimed organic cotton and 30 per cent reclaim...
