From Movement to Recovery
Designed to Feel & Heal

Meet eir bands

Modular | Wireless | App-Controlled Electrical Muscle Stimulation

eir bands use electrical impulses to stimulate targeted muscles, providing a responsive experience that feels every movement within digital environments. As muscles interact with virtual surroundings, the bands adapt in real-time to deliver motion stimulation to those muscles.

This interactive approach aids muscle training by activating and strengthening muscles during immersive sessions, promoting muscle health, endurance, and recovery in a personalised, engaging way.

One core technology. Two applications.

Choose your experience:

  • One wearable for all your muscle needs. eir bands turn your muscle care into a connected, intelligent, and sensory experience from high-intensity VR workouts to post-workout relief and relaxation. 

    • Real-time Muscle Activation in VR: Controlled EMS signals sync with your virtual movements to enhance muscle activation and boost performance.

    • Enhanced Performance: Activate and strengthen muscles through targeted EMS programs, even passively, without active movement.

    • Pain management: Relieve tension and muscle discomfort with precise TENS stimulation designed for targeted pain management.

    • Massage & Relaxation: Ease soreness, stiffness, and fatigue anytime, anywhere with soothing pulse patterns that promote circulation and relaxation.

Launching January 2026.
