HIDIZS MP145 PRO Review - Sean Talks Tech

Sean Talks Tech describes the HIDIZS MP145 PRO as more than a simple update, presenting it as a rethink of what a reference planar IEM can achieve. For listeners searching for an over-ear-like experience in a portable form, he finds plenty to appreciate in its presentation.

Premium Design and Practical Modularity

Sean finds the whale-inspired design beautiful and describes the aluminum construction as substantial, heavy, and premium. Although the ergonomic shape distributes the 9.5g-per-side weight well and provides a stable fit, he warns that the large housings may require some adjustment for smaller ears. He also found it difficult to achieve a perfect seal with the included Sea Anemone ear tips, although isolation was decent once properly fitted. 

The cable also receives praise. Sean describes it as rugged, thick, substantial, and less prone to tangling. He particularly loves the modular design, which allows switching between the included 4.4mm and 3.5mm terminations without replacing the entire cable. He also finds the two-pin connection secure.

Sean also appreciates HIDIZS’ support for whale and dolphin conservation, seeing it as an additional sense of purpose behind the whale-inspired design. 

Refined and Accurate Sound

For Sean, the MP145 PRO distinguishes itself through a refined, reference-oriented presentation that prioritizes accuracy. He says the artificial character he sometimes associates with planar drivers is effectively gone.

Bass is one of its strengths, with Sean describing it as masterfully handled with an emphasis on quality. Sub-bass reaches deep with tight, tactile extension, while the mid-bass remains clean and detailed. He finds the speed particularly effective with fast and complex tracks and calls the textured bass exceptional. He does note that dedicated bass enthusiasts may want more raw impact, as the tuning prioritizes texture and control over sheer quantity. 

The transition into the lower mids is seamless, while male vocals carry realistic weight. Moving upward, Sean describes the presentation as transparent and revealing. Well-recorded tracks can sound breathtakingly clear, but he also finds the MP145 PRO unforgiving of poor mastering and low-quality files. 

Detailed Treble and Expansive Soundstage

Sean considers the treble extension a major strength of the MP145 PRO. It delivers a high level of micro detail, allowing him to hear elements such as the trailing edges of cymbal crashes and subtle breaths from vocalists. He particularly appreciates that the treble does not become harsh even at louder listening volumes.

For Sean, however, the soundstage is the star of the show. He describes it as very wide and approaching the sensation of open-back over-ear headphones. Imaging is razor sharp, making it possible to pinpoint the positions of guitars and backup singers.

This combination creates what Sean calls an immersive, holographic feeling, making music resemble a live performance rather than simply a recording.

Overall Assessment

Sean sees the MP145 PRO as a more technical, precise, and reference-oriented evolution of the original. Its three tuning filters provide some flexibility, with silver adding more high-end sparkle and red bringing additional warmth to the low end.

He considers it arguably one of the best-tuned planar IEMs for listeners who value detail, accuracy, sharp imaging, and expansive staging. However, he notes that the oversized housings may challenge smaller ears and that its revealing presentation can be unforgiving of poor recordings.
