This love could only be buried deeply in the heart. Our designer uses a deep dark paint on the remaining IEM shell to symbolize a girl's contour and to represent the mystic night &amp; the couple's intense love but the sadness being left behind. “Margarita's Phantom” comes in a warm yellow main tone. Yellow relates to our warm sunlight which brings joy &amp; hope. It signifies us to treasure our present &amp; to love our life. We have decorated the faceplate with yellow optical particles, the salt-like glowing glints hint at us as the tears we shed in old times. Our designer outlines subtle lines to blend all these into the design.\n\n\n\n\n\nDriver Configuration\n7mm Titanium Coated Dynamic Driver provides powerful &amp; deep driving bass, our QOA custom QA11021 BA is a mellow-toned one with wide bandwidth, working as a seamless connection between the bass &amp; treble. The Sonion EST65DA01 compound driver comes with a superior treble extension, making the listening experience even more ethereal and open.\n\n\n\n\n\nProfessional Three-Way Frequency Crossover\nIn order to get the best performance out of the multi-driver arrangement on the Margarita, QoA has professionally adjusted the drivers in a three-way frequency crossover. After the crossover, Margarita also gets three independent acoustic ducts going from the appropriate drivers to the ear nozzle for interference-free, smooth sound reproduction. QoA Margarita provides a clean performance with ultra-low distortion and clean background.\n\n\n\n\n\nUnique Design\nQueen of Audio has designed the Margarita using high-precision 3D printing technologies. The pair is available in two striking color options, Yellow Margarita's Phantom and the Black Fragment Of Memories. Both the colors feature uniquely hand-crafted face covers that just provide an eye-catchy design to the pair.\n\n\n\n\n\nErgonomic design\nIn order to provide more comfortable fi","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/products/retouch_2022060719570355.jpg?v=1655116494","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/retouch_2022060720000034_1.jpg?v=1655116494","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/retouch_2022060714334542.jpg?v=1655116494","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/retouch_2022060714334542_8a7119e2-95e3-4079-aa01-bcd103aa7b4d.jpg?v=1655116494","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/IMG_20220607_204923.jpg?v=1655116494","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/IMG_20220607_205054.jpg?v=1655116494"],"price":549,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:47.525Z"},"share_url":"https://firestarter.network/l/lst_7MupHwNf","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
