{"type":"firestarter.listing","listing":{"id":"lst_Fe_dT7gV","product_name":"THIEAUDIO Hype 4 MKII","category":"Earphones/IEMs","description":"\nCompletely Redesigned for Performance\nThe HYPE 4 MKII is not just a retuning - it’s a complete redesign from the ground up. Featuring brand new balanced armature drivers from Knowles, second generation IMPACT2 sub-woofer system, and a new engineering approach, the HYPE 4 MKII makes leaps in both tonal and technical performance.\n\n\n\n\nGen 2 IMPACT2\nThe HYPE 4 MKII incorporated the latest generation of the IMPACT2 sub-woofer system, which is shared with the Monarch MKIV. Two 8mm composite diaphragm dynamic drivers encased in THIEAUDIO’s proprietary pneumatic acoustic chamber pumps out tight, focused, and deep sub-bass thumps - all while keeping the rest of the frequency range clean and neutral. \n\n\n\n\n\nKnowles Balanced Armature Drivers\nThe MKII design was developed from the ground up. Using imported American Knowles balanced armature drivers, the HYPE 4 MKII makes no compromises when it comes to tonal and technical excellence. Two of the latest Knowles RAB series drivers focus on rich and pronounced low-mids, while separate ED-33465 driver layers up on mid-treble frequencies. This crossover strategy significantly enhances imaging capabilities as well as tonal depth in the midrange. A single Knowless RAD-33518 ultra-tweeter has been strategically positioned within the nozzle for an upper treble extension that rivals electroststic and planar drivers. \n\n\n\n\n\nEnhanced Tuning Approach\nThe key to THIEAUDIO’s global success has been its attention to tonal balance. We took a step back to assess what characterizes the intersection between studio neutral and musical enjoyment, and have incorporated our new tuning approach into the HYPE 4 MKII. The sub-woofer output is thunderous, with a 9dB output, but with a sharp cutoff at 150Hz, the bass is precise and free from bloating. The midrange features a lush 400Hz hump, while being neutral between the bass and treble cutoffs. This allows the midrange to be naturally warm, without being muddy, while remaining true to a studio monitor pre","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIOHYPE4MKII_9_d439f67a-4f90-462e-b227-ec16c731f2c7.jpg?v=1762420414","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIOHYPE4MKII_12_72f3ab03-df73-40eb-bdec-881fb838d83b.jpg?v=1762790344","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIOHYPE4MKII_2_.1_75243c09-4551-4201-af7f-d46083ccdf57.jpg?v=1762790344","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIOHYPE4MKII_8_8f56c62f-cea8-4b24-a533-50f8bc1bea8b.jpg?v=1762790344","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIOHYPE4MKII_11_0a9a5b9f-1a4a-4916-b485-6227f52b00e3.jpg?v=1762790344","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIOHYPE4MKII_5_bc01a9b2-6073-4577-9989-76b2150a4431.jpg?v=1762790344","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIOHYPE4MKII_3_76d21ad8-1e02-4d6c-8997-d391082bd4a1.jpg?v=1762790344","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIOHYPE4MKII_2_7867a8ae-f667-4f09-b8f9-416f3d366c97.jpg?v=1762790344","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIOHYPE4MKII_1_655d4d16-659d-450e-b23d-031037400aff.jpg?v=1762790344","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIO_HYPE4_MKII_48.jpg?v=1762511566","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIO_HYPE4_MKII_49.jpg?v=1762511566","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIO_HYPE4_MKII_50.jpg?v=1762511566","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIO_HYPE4_MKII_51.jpg?v=1762511566","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIO_HYPE4_MKII_52.jpg?v=1762511566","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/THIEAUDIO_HYPE4_MKII_46.jpg?v=1762511566"],"price":399,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:44.534Z"},"share_url":"https://firestarter.network/l/lst_Fe_dT7gV","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
