EPOC X has been designed with the following improvements:
- Rotating headband that can be positioned on top or at the rear of the head — ideal for sleep studies or accommodating a head support.
- Electroplated electrodes to reduce oxidation and sustainably designed sensors — no more sensor clip breakages.
- Opening at the rear of each sensor allows for easy rehydration without moving the headset.
- Adjusted and relocated amplifiers to reduce noise and improve signal quality.
- Updated antenna and radio for improved headset performance.
- Shipped in a protective and reusable travel case.
