Driver Setup
For the driver setup, Xiaomi chose to use a 2×2 setup with 2 Balanced Armature (BA) drivers and 2 dynamic drivers.
Balanced Armature drivers are popular because the combine the best of both worlds – fine detail in sound via the Balanced armature drivers whilst the dynamic drivers deliver a strong bass punch. What’s special about the dynamic driver setup is that they have a specially designed 2 driver unit which uses a large and small membrane. Most IEMs use only a signal dynamic driver, whilst this one uses two to give extra power.
Bluetooth Reciever
Xiaomi includes a clip-on Bluetooth 5.0 receiver with LDAC support with these IEMs. The receiver outputs with 3.5mm standard audio socket, so it could used to other headphones as portable Bluetooth receiver.
