Similar to Wraith, ODIN features 11 drivers, but this is a tri-hybrid (tribrid) design with 2DDs, 5BAs, and 4ESTs. On paper it does look like a combination of Wraith and Legend X:
- 2x DD W9+ drivers (sub-bass and bass)
- 2x BA low-mid drivers
- 2x BA mid drivers
- 1x BA mid-high driver
- 2x EST high drivers
- 2x EST ultra-high drivers
But there are some noticeable changes. 9mm Dynamic Driver, referred to as W9+ (Weapon IX+) has been updated and noted by “+” suffix. This enclosed woofer in a tuned bass-reflex system now boasts a larger internal coil diameter to improve its sound performance. The 5BAs are proprietary drivers, and Sonion quad EST drivers are the next gen update with a different tuning and all new single transformer design. Abbreviated as EIVEC (Empire Intelligent Variable Electrostatic Control), this single transformer is designed to drive efficiently four EST drivers.
Another change in the design is all new synX crossover with 7-way Crossover Network designed specifically to handle tribrid combination of drivers in ODIN design. The main function of ODIN synX is to control and to balance the frequency response of all 11 drivers, keeping the tuning of DD/BA/EST in a coherent unison.
Last, but not least, is A.R.C. resonance control tech, utilized in all EE iems. Its initials stand for Anti-Resonance Compound which is a proprietary coating that eliminates unwanted vibrations and resonance within IEM. Basically, this compound serves as a dampener to absorb the unwanted resonance.
With all this tech and 11 drivers, including 2 dynamic and quad EST with a separate transformer, ODIN shell size is still relatively compact for universal design. The acrylic shell material is smooth, the short nozzle slightly flares out at the top for a better grip with eartips, and you have 5-bore opening at the tip of the nozzle for separate sound tubes. Similar to what I have seen in Legend X with its dual W9 drivers, here you can also find 3-pinhole vent on the side of the shell. And also, similar to LX, expect a driver flex (pop) when you put these in your ears.
But the highlight of the shell design is Bifrost faceplate, exclusive to ODIN. According to EE, to optically simulate the mythological rainbow between Asgard and Midgard, Bifrost faceplate features nine individual polymer layers built in three proprietary lamination steps. The visual multi-layered effect is beautiful and does look 3D. On top of that, right shell features artwork of Empire golden wings and left shell features Valknut 3 interlocking triangles symbol associated with ODIN, the same matching symbol as in y-split of the cable.
I tried to capture the artwork of the faceplate in pictures, the best I can. But I still think it looks a lot better in person.
