THIEAUDIO HYPE 4 MKII In-Ear Monitors

The Thieaudio Hype 4 MKII are hybrid multi-driver in-ear monitors, designed as a direct evolution of the original Hype 4 to extend their architecture while enhancing their acoustic control. They feature the second generation of the IMPACT 2 subwoofer system, based on two 8mm dynamic drivers with composite diaphragms housed in a proprietary pneumatic acoustic chamber, generating deep, controlled sub-bass while effectively isolating the rest of the spectrum.

Beyond this foundation in the sub-bass range, the design relies on a new implementation of Knowles balanced armature transducers, organised around a dedicated frequency distribution. This approach allows for more precise management of the low-mid range, a better-defined mid-high transition and an extension into the very high frequencies directly integrated into the acoustic duct, ensuring extended and consistent reproduction without tonal breakage.

Thieaudio Hype 4 MKII : Balanced frequency response

The acoustic tuning prioritises controlled impact and tonal warmth. The subwoofer delivers an elevation of approximately 9dB, while applying a sharp cut-off at 150Hz, preserving bass precision without encroaching on the midrange. The midrange features a measured boost around 400Hz, providing natural warmth while remaining neutral between transition zones, which maintains clear reproduction while remaining faithful to the original. The treble adopts a deliberately delayed decay, favouring the recovery of micro-details and the openness of the sound stage, while avoiding any perceptible aggressiveness.

This sound consistency is based on 4-way acoustic engineering, combined with a system of 4 acoustic tubes and 7 independent passive components, ensuring precise control of interactions between transducers. Mechanically, each Hype 4 MKII is CNC-machined from solid aluminium blocks, then finished and anodised by hand to guarantee structural rigidity and stability over time.
