With a diaphragm made from bio-nanofiber composite, it ensures a higher magnetic flux compared to regular dynamic drivers. The additional acoustic energy achieved results in improved transient response and better energy conversion efficiency. Twin magnetic circuits stabilize the diaphragm operation while dual chambers, designed from the dual magnetic circuit concept, produce independent acoustic spaces. These spaces offer benefits such as robust and adjustable low-frequency response, clearer and purer vocal and midrange reproduction.\n\n\n   \n\n  \n\n \n\n\t\n  \n\n  \n\nKnowles SWFK-31736 Compound Balanced Armature Driver\n\n\n  \n\nThe MS3 In-Ear Monitors feature a classic Knowles compound balanced armature driver, SWFK-31736, for delivering high and super-high frequencies. This driver produces clear and bright high-frequency output with great ductility and long-lasting reverberation. The superb super-high frequency presentation brings out the richness in emotions and overall musical details, providing a boundless auditory experience.\n\n\n   \n\n  \n\n \n\n\n  \n\n  \n\nAircraft Grade Aluminum Alloy Single-Piece Molding Shell\n\n\n   \n\n  \n\nThe shell and faceplate of the MS3 In-Ear Monitors are carved from aircraft-grade aluminum alloy using a five-axis CNC machine. The cavity, designed in line with human ear ergonomics, and anodized surface maintain prolonged cleanliness. The striking black-oxidized flame-like panel design adds a dynamic touch.\n\n\n\n\n\n \n\n   \n\n  \n\n \n\n\n  \n\n  \n\nHidizs Air Pressure Sound Tuning Filter\n\n\n \n\n   \n\nHidizs introduces a replaceable air pressure sound tuning filter design, a feature welcomed by audio enthusiasts. By simply changing the tuning filter, one can experience a nearly brand new auditory perception. The MS3 comes with three interchangeable air pressure","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/02_1be4009a-83e7-4cc1-a11e-fd06c66a7ec6.jpg?v=1688548991","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/MS3_9.jpg?v=1688548991","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/MS3_3.jpg?v=1688548991","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/MS3_8.jpg?v=1688548991","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/MS3_2.jpg?v=1688548991","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/MS3_6.jpg?v=1688548991","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/MS3_11.jpg?v=1688548991","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/MS3_1.jpg?v=1688548991"],"price":169,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:44.166Z"},"share_url":"https://firestarter.network/l/lst_846jjf4Z","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
