IEMs can be tricky to assemble.
When the drivers are installed without a dampening compound, the added resonance can make for an unpleasant listening experience.
As a result, the efficiency of each driver is decreased and your tunes aren't reproduced with precision.
This is not a worry with Empire Ears!
The Legend Evo IEM utilizes ARC technology, a unique dampening coating applied during assembly.
Consequently, the efficiency of each driver is increased, resonance is decreased, and bass is deepened.
