Sometimes, a product name will tell you everything you need to know. Kenwood’s new Glass Core and Glass Core Pro in-ear headphones don’t have their title for no reason. The ANC-featuring buds utilise glass diaphragms. According to the company, it’s an industry first that “suppresses unwanted vibrations and reproduces all the information from low to high frequencies without loss” (translated using Google Translate).
