The AS24 is available in two versions. The price difference between them is not that big. But if you are a person with your style preferences, its Tunable version is a very good one to try.\n\n\n\n\n\n\n12 BA Drivers, This Earphone Has No Room for More\nThe AS24 has 12 BA drivers per side, which breaks the audio hardware ceiling. 31736 array-design BA is responsible for high and ultra-high frequency, providing smooth scalability and rich sound details. Customized 29689 BA is responsible for mid-frequency, bringing a clean vocal and transparency in mid-range. 30019 BA is responsible for high-frequency, providing a refined sense of layering and realistic on-site experience. The newly designed 22955 BA is responsible for low-frequency, bringing a powerful and resilient bass.\n \n\n\n\n\n\nPrecise Structure Like an Artwork\nThe traditional \"u\" shaped reed is designed for hearing aids, and its bending process may lead to poor stability and consistency. This time, KZ has designed a \"trident\" reed specifically for HiFi earphones, which is more accurately centered between the magnets. This design can enhance sound density, reduce distortion, and achieve better transient performance. Compared to all previously balanced armatures, the newly designed 22955 BA can deliver more powerful and resilient bass. The new generation 29689 BA can deliver spacious, elegant, and natural sound with superior treble extension.\n\n\n\n\n\n\nCustomized Tuning for More Flexibility\nAS24 has dual tuners and 8 switches. There is one tuner on the top and one on the outside of the chamber, each with four level switches. By flipping the switches, you can freely adjust and control the low-frequency, medium-frequency, high-frequency, and ultra-high frequency of your earphone.\n \n\n\n\n\n\nA Design that Combines Elegance and User Experience\nThe ","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KZAS24_7.jpg?v=1687146237","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KZAS24_1.jpg?v=1687146237","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KZAS24_2.jpg?v=1687146237","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KZAS24_3.jpg?v=1687146237","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KZAS24_8.jpg?v=1687146237","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KZAS24_6.jpg?v=1687146237","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KZAS24_5.jpg?v=1687146237","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KZAS24_4.jpg?v=1687146237"],"price":114,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:46.927Z"},"share_url":"https://firestarter.network/l/lst_P2BJUk5K","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
