Hidizs MP145 is a single-driver planar IEM built around a 14.5 mm planar magnetic transducer (30 Ω, ~104 dB/Vrms), housed in a milled aluminum shell. It ships with screw-on tuning filters that make modest shifts to bass/treble balance rather than rewriting the signature. Hidizs markets the MP145 as calibrated toward the H-2019 target and lists a $199 MSRP (often discounted on the official store).
Sonically, the MP145 presents a U-shaped tuning with an audible sub-bass lift, restrained upper-mid gain, and treble that’s energetic but can show a ~5 kHz edge with a bit of upper-treble sparkle depending on the filter used. Resolution and separation are solid for the price, with fast planar transients and convincing macrodynamic impact; staging is average-wide but imaging locks in positions cleanly. Independent measurements/reviews note the filter set’s subtle effect, good detail retrieval for the bracket, and only moderate air/extension versus the best planars.
Build quality is robust, though the large shells and thick nozzle may challenge smaller ears; weight is ~9.5 g per piece and isolation is decent when sealed well. Given frequent street prices around $129–$159 on the brand store, value is strong for those wanting planar speed with a fun, sub-bass-tilted balance; just don’t expect expansive stage or the most airy treble. Overall, MP145 reads as a well-executed, filter-tweakable planar that prioritizes punch and clarity over ultimate refinement.
