We've named Hidizs S9 Pro Plus "Martha" because "Martha" was the name of the last surviving female Passenger Pigeon, the largest flocking bird species ever to have existed on Earth. After 109 years since the extinction of the Passenger Pigeon, in commemoration of this magnificent species, the professional acoustic brand, Hidizs, has chosen to name their third-generation HiFi Balanced Dongle DAC , the S9 Pro Plus, as "Martha." This "Martha" choice serves as a reminder that our world is one of diversity, where we cherish nature and life. Through this unique naming approach, we hope to encourage more people to remember these beautiful creatures. If this is your first encounter with the Passenger Pigeon through Hidizs, then we've truly achieved our purpose.
