Synergy
Efficiency
The MP145 Golden Titanium has a sensitivity of 104 dB @1kHz mW and an impedance of 30Ω, making it easy to drive from various sources such as a dongle DAC or a laptop computer.
Based on my testing, I was able to satisfyingly drive the MP145 Golden Titanium with the 7hz SEVENHERTZ 71 via single-ended and the ddHiFi TC44Pro via its balanced output.
Between the two, I preferred the TC44Pro since its naturally more neutral tonality ensured that the bass bleed of the MP145 Golden Titanium would not be exacerbated by a warmer DAC such as the 7hz SEVENHERTZ 71.
The additional headroom of the TC44Pro also slightly improved the staging of the IEMs, giving it a more atmospheric listening experience.
Testing the MP145 with a more powerful desktop amplifier such as the FiiO K11 and the TempoTec March III M3 did increase the staging and dynamics a bit, but not enough to come at the cost of portability and ease of use.
Pairings
In my testing, I found that the MP145 Golden Titanium paired best with the ddHiFi TC44Pro since it maintained a neutral tonality, whilst also providing sufficient power to drive the Hidizs’ 14.5mm planar driver.
The 7hz SEVENHERTZ 71 was able to sufficiently drive the MP145 as well, however, I did not like how the additional warmth of the 71 compounded on the somewhat muddy mid-range response of the MP145 in certain tracks.
Select Comparisons
Moondrop Blessing 3
Technical
The Moondrop Blessing 3 makes use of a dual dynamic driver and 4 BA drivers, whilst the Hidizs MP145 Golden Titanium makes use of a single 14.5mm Planar magnetic driver.
The Blessing 3 has a lower impedance of 14.8Ω and a sensitivity of 100 dB/mW as opposed to the 30Ω impedance and 104 dB sensitivity of the MP145. In practice, I found that the Blessing 3 was harder to drive than the MP145 Golden Titanium
Design
The Blessing 3 makes use of a more common resin shell with a separate metal faceplate. The metal faceplate of the Blessing 3 is constructed out of polished stainless steel, giving it a mirror-like finish.
The resin shell used by the Blessing 3 is also transparent in the finish, showing off the multi-drive system of the IEM.
The MP145 on the other hand is a far departure from this more common Chi-Fi build philosophy. Constructed almost entirely out of titanium with a gold finish, the MP145 is significantly denser than the Blessing 3, whilst also making use of a unique whale-inspired geometric pattern for its faceplate.
Performance
The Blessing 3 has a neutral sound signature, while the MP145 Golden Edition has a more exciting, U-shaped sound signature that leans towards the warm end. The MP145 Golden Titanium has a stronger and deeper bass performance and a slightly higher level of bass articulation and texture playback.
Male vocals have more body on the MP145 Golden Titanium. However, all other instruments and sounds within the mid-range are presented in a more forward manner on the Blessing 3.
The MP145 Golden Titanium also tends to have its bass bleed into the mid-range, while the Blessing 3 is simply a class leader in maintaining a clear yet natural mid-range response.
The Blessing 3 is still significantly more resolving in the treble region, but the MP145 Golden Titanium is still more sibilant. This is quite surprising since, in my experience, better-resolving IEMs usually have a more sibilant presentation.
Hidizs MP145 (Standard Edition)
Technical
Being essentially identical in terms of tech specifications, both the Golden Titanium and the standard version of the MP145 make use of a large 14.5mm planar magnetic driver with an impedance of 30Ω and a 104db @1kHz mW sensitivity. In practice, neither model was harder to drive than the other.
Design
In terms of shape and size, both versions of the MP145 make use of an ergonomic shape inspired by whales and Hidizs’ collaboration with WDC. The key difference between the two is the standard version’s use of aluminum and the Golden Titanium version’s use of titanium.
The titanium version of the MP145 is twice as heavy, making it feel much more premium but also less comfortable in the process. The gold finish used in the Golden Titanium version of the MP145 is also more prone to micro scratches from daily wear and tear.
Performance
Since both the standard and Golden Titanium Version of the MP145 have the same internal specifications, their sonic performance is quite similar, only with slight but noticeable differences caused by the different acoustic properties of aluminum and titanium.
Both IEMs have a U-shaped sound signature, but the Golden Titanium version leans more towards the warm side, giving it more sub-bass performance and less treble energy.
Beyond this, I also found that the Golden Titanium version had better staging performance than the standard version
An immediate standout was how extended sub-bass drones sounded more atmospheric and subtle on the Golden Titanium version, with the Standard version being unable to replicate such a tonality.
This gives the Golden Titanium version a more relaxing and laid-back tonality as opposed to the standard version. Neither version is better than the other sonically, it just depends on the taste of the listener.
Our Verdict
Hidizs celebrated their 10th anniversary with a bang by releasing a one-of-a-kind, (more specifically a 1 of 199), pair of IEMs built using a gold-finished titanium material that is very rarely seen in the Chi-Fi space.
Iterating upon an already popular set of IEMs, the Hidizs Golden Titanium Edition is a denser and more luxurious version of the original MP145, and also with a slightly warmer and more laid-back sound signature.
This more laid-back signature is definitely not for everyone. I for one would prefer a little more treble energy, but no one can deny that this commemorative pair of IEMs is something special.
