Moondrop Variations

Moondrop Variations


Moondrop has officially released its highly-anticipated tribrid set of IEMs, the Moondrop Variations. It has been one of the most anticipated projects from Moondrop in recent times. With Variations, Moondrop is bringing us three different technologies put together inside 3D printed ear cavities. The pair utilizes the power of a powerful Dynamic driver, two High-Performance Balanced Armature drivers, and two Highly-Resolving Electrostatic drivers to push the limits of high-resolution audio and produce an all-new experience for its users. Moondrop Variations has a price tag of 520$, It is available with us on our HiFiGo store. Check out more details here.

Perfect Tribrid Configuration For Perfect Sound

Moondrop has carefully chosen the driver configuration for the Variations. They have experience in implementing EST drivers before like in their flagship Solis IEMs. Moondrop has equipped the Variations with a five-driver configuration in a three-way crossover. A 10mm large LCP diaphragm dynamic driver is tuned to provide a powerful lower-end response, two Softears customized balanced armature drivers are tuned for a rich mid-range response, and two Sonion EST drivers are there for super-detailed treble frequency response.


Highly-Consistent Full-Frequency Response

Moondrop has improved over the hybrid crossover design of Blessings 2. This has been done to achieve a highly consistent full-frequency response. They have designed a 3D printed precision acoustic channel combined with damping materials. Variations show very ideal frequency response with phase indicators.


Ergonomic Fit With Skin-Friendly Resin Material

Moondrop uses high-precision 3D-printing technology to design ergonomically shaped ear cavities providing a comfortable fit for most users. The cavity here in Variations is made using high-quality medical-grade resin material with the same high-precision 3D printing process. The cavities have sand-blasted and hand-polished stainless steel face panels that give an excellent texture and look to the pair.


Moondrop's VDSF Target Response Tuning

Moondrop Variations is tuned based on Moondrop's famous VDSF target response to bring a true and accurate sound response with a wide sound stage presentation. With its powerful tribrid driver configuration, the pair achieves a total harmonic distortion of less than 1% delivering a melodious and clean sound response that will complement different genres well.

High-Purity Single Crystal Copper Cable With Detachable Termination Plug

Moondrop Variations comes bundled with a high-purity PCC Coaxial Monocrystalline copper cable that adopts a coaxial structure with replaceable termination plugs. The package includes 3.5mm single-ended, 2.5mm balanced, and 4.4mm balanced termination plugs. The high-purity single-crystal copper material ensures a pure sound signal transmission with low internal resistance.


Easy To Power

With a low impedance rating of just 15.2 ohms and high sensitivity of 118dB/Vrms, the Moondrop Variations is a highly sensitive pair. It can be powered right off a regular smartphone without the need for any external amplifier or extra devices.


Pricing & Availability

Moondrop Variations is officially released today with an attractive price tag of 520$. It can be bought from our store from here.
