Dunu 242 VS ThieAudio Hype 4 MKII

The Dunu DN242 (often referred to as “242”) is an eight-driver tribrid IEM featuring 2 dynamic drivers, 4 balanced armatures and 2 micro planar drivers per side, coordinated via a multi-way crossover to cover the full spectrum. With an impedance of around 35 Ω and sensitivity of about 110 dB/mW, it is easy to drive from most modern sources while still benefitting from higher-quality DAC/amps. The lightweight resin shells (~6 g per side) and modular Q-Lock style cable provide a practical, comfort-oriented package at an MSRP of roughly $349, placing it in the competitive upper-midrange bracket.

Sonically, the DN242 presents a neutral-bright, vocal-focused tuning with restrained but articulate bass, a clear midrange and energetic treble. Reviewers consistently note that the midrange is clean and evenly toned, giving vocals strong intelligibility and preserving textural nuance, while the dual dynamic drivers prioritize control and definition over sheer quantity in the low end. The upper mids and treble are described as bright and very resolving, with quick transients and a “spry” character that pushes vocals and leading edges forward, but can introduce a touch of sharpness or upper-treble bloom for more treble-sensitive listeners unless managed with careful tip choice.

Technical performance is a strong point for this price tier: users and reviewers describe detail retrieval as above average, with disciplined, non-boomy bass, stable imaging and a stage that organizes complex material without obvious congestion, even if sheer width is not class-leading. The combination of clarity, separation and midrange focus makes the DN242 particularly suitable for vocal, acoustic, jazz and classical material where precision and neutrality matter more than warmth or powerful slam. However, its moderate low-end emphasis and bright top mean it is less ideal for listeners seeking a very relaxed or bass-heavy presentation, especially given the number of warmer alternatives around the same price.

The ThieAudio Hype 4 MKII is a $399 hybrid in-ear monitor built around a 2DD + 4BA array, using dual 8 mm dynamic drivers for low frequencies and four Knowles balanced armatures for the mids and treble within a 4-way crossover network. Its CNC-processed aluminum shells and a modular 7N ultra-OFC copper and silver-litz cable, supplied with both 3.5 mm and 4.4 mm terminations, emphasize build robustness and system flexibility over cosmetic experimentation.

From a tuning standpoint, the Hype 4 MKII targets the intersection of studio-neutral and musical, with the Gen 2 IMPACT2 dual-dynamic module delivering roughly a 9 dB sub-bass lift that rolls off sharply around 150 Hz so that most of the extra energy sits below the mid-bass region. ThieAudio also describes a mild 400 Hz emphasis in the midrange and a treble region tuned with slower decay, aiming for natural vocal weight and sustained high-frequency detail without pronounced sharpness. Taken together, this suggests a neutral-with-sub-bass-boost presentation that prioritizes controlled low-end impact and a slightly warm midrange over an ultra-lean, clinical reference tonality.

On the technical side, the dual 8 mm woofers, 4-way crossover, and discrete Knowles drivers for ultra-high, high, and mid bands are engineered to enhance imaging precision, separation, and depth, with retailer and product literature consistently pointing to improvements in clarity and spatial presentation over the original Hype 4. With a rated impedance of 18 Ω and sensitivity of 101 dB @ 1 kHz, it should be straightforward to drive from portable sources, though cleaner amplification will likely better expose its microdetail and dynamic swings. Considering its mid-range price and the dense competition around $400, the Hype 4 MKII reads as a technically ambitious and carefully tuned option, offering strong value without fundamentally disrupting the hierarchy of higher-end models.
