fiil is a new brand of music devices by the Chinese rock star Wang Feng. Benefiting from his over 20 years of expertise in music, we succeeded in combining the most excellent audio components with great wearing comfort. The four integrated speakers ensure a huge bandwidth of sound quality. fiil is striving for the essence of audio devices: using outstanding materials for important components (such as anodized aluminum caps for improved sound or liquid silicone earbuds to block external noise), while removing all unnecessary elements. This way, fiil’s design language creates a sense of pureness and makes these headphones the perfect stage for any style of music.
