The home EMS suit that comes with a coach
The Solo is the complete kit: your wireless Onyx EMS Suit, the Power Box that runs it, and the Onyx App that controls it from your phone. Unlike a box you're left to figure out alone, every Onyx comes with a free onboarding session with a Volt Box coach, the same team that has run EMS studios in Saudi Arabia since 2021.
What's in the box
1 × Onyx EMS Suit (wireless, 20 dry electrodes, fully adjustable)
1 × Onyx Power Box (Bluetooth control unit, magnetic mount)
1 × Onyx App licence (iOS and Android: strength, fat-loss, endurance and recovery programmes)
1 × magnetic charging cable
1 × storage bag
1 × free 30-minute onboarding session with a coach (in person in Riyadh, video call everywhere else)
How it works
Put on the suit and clip on the Power Box.
Open the Onyx App and connect over Bluetooth.
Pick a programme and set the intensity for each muscle group.
Train for 20 minutes. Save your profile and reuse it next time.
What to expect
Most clients train one to two times a week. With consistent use and sensible nutrition, changes in strength and tone typically show in 4 to 6 weeks. Your onboarding session sets the right intensity for your fitness level from day one.
The maths against studio EMS
Studio EMS in Saudi Arabia typically costs SAR 250 to 400 per session. The Onyx pays for itself in 14 to 22 sessions. Train once a week and you break even in 14 to 22 weeks.
Made on demand
Every Onyx is built when you order it, so there's no warehouse markup. Allow up to 3 weeks to build, then free delivery anywhere in Saudi Arabia (SAR 99 to the rest of the GCC, SAR 300 international).
Guarantees
30-day returns on unused kits in original packaging (suits only if the inner seal is unopened) · 12-month warranty on the Power Box · 90-day warranty on suit, electrodes and cables · Damaged on arrival? We replace it free.
