Akros considers the HIDIZS MP145 PRO a mature and technically capable planar IEM that successfully responds to feedback surrounding the original model. After spending time comparing the two generations, he sees the MP145 PRO as a more refined, audiophile-oriented interpretation of the series, with greater emphasis on clarity, technical performance, and planar characteristics.
Refined Design and Build Quality
Akros finds very little to fault regarding the MP145 PRO’s construction and appearance. Although the shell is large, Akros says it fits his ears nicely and feels relatively light in his personal use. He also highlights its CNC-machined aluminum alloy construction.
The updated nozzle system is another improvement he notices. Rather than changing only the end portion, the entire nozzle can now be exchanged. Three options—silver, gold, and red—allow listeners to adjust the presentation according to their preferences.
For Akros, the red nozzle provides the most balanced presentation and is his personal favorite. He finds it musical while still maintaining the planar qualities he enjoys.
Cleaner, More Precise Bass
One of the most noticeable changes for Akros is the bass presentation. He describes the MP145 PRO’s bass as cleaner, more dynamic, and more precise.
With his preferred red nozzle, the planar bass remains capable of filling out the music competently. The cleaner bass also gives the mids additional room to open up, allowing more detail to come through.
For listeners seeking a more audiophile-oriented presentation, Akros believes the MP145 PRO delivers that character particularly well.
Detailed Yet Musical Mids
The mids are another area Akros praises. He repeatedly describes them as clean and detailed while emphasizing that their more precise character does not remove musicality.
According to Akros, the MP145 PRO maintains a high level of musicality while presenting the mids with greater clarity. This contributes to the cleaner overall direction he associates with the new model.
Compared with the original’s more organic presentation, Akros finds the MP145 PRO’s mids somewhat more clinical. Even so, he believes they retain a high level of musicality rather than becoming cold.
Improved Technical Performance
Akros describes the treble as clean, detailed, and well extended. Although his graph shows slightly less energy above 10kHz than the original, the reduced bass makes the MP145 PRO sound brighter and more open overall.
Most importantly, he identifies three clear improvements: In his comparison, Akros perceives a bigger soundstage, better imaging, and slightly improved detail retrieval. These qualities help define the more technical and refined direction of the MP145 PRO.
Overall Assessment
Akros sees the MP145 PRO as a mature, cleaner, and more technical interpretation of the original, with improved imaging, soundstage, and slightly better detail retrieval in his preferred red-nozzle configuration. Its interchangeable nozzles also provide a valuable versatility advantage in a highly competitive planar market.
However, he does not consider it an automatic upgrade for every MP145 owner. He sometimes prefers the original’s fuller bass, more organic mids, and more natural tonality, viewing the PRO as closer to a sidegrade unless additional clarity and detail are the priority. Overall, he places it among the leading planar IEMs rather than declaring it a new category winner.
