What is Energy Sistem's Open Sound technology?
Open Sound technology is Energy Sistem's open audio system that directs sound directly to your ears without sealing the ear canal.

Ideal for outdoor sports, running, and urban use.
Are open-back headphones safe for sports outdoors?
Are open-back headphones safe for sports outdoors?
Yes, and that is precisely one of their greatest advantages. By not isolating your ear from outside sounds, Open Sound open headphones allow you to hear traffic, signals, or other people's directions while you train. In addition, our models are IPX4 sweat and splash resistant certified, making them perfect for running or any outdoor sports activity.
What's the difference between open-back headphones and noise-cancelling headphones?
What's the difference between open-back headphones and noise-cancelling headphones?
They are opposing concepts. Active Noise Canceling (ANC) headphones block out external sound for a more immersive listening experience, ideal for concentration or travel. Open Sound headphones, on the other hand, do not seal the ear canal and allow ambient sound to reach you naturally, prioritizing safety and situational awareness. Each technology has its moment: you choose when you want to isolate yourself and when you want to be connected to the world.
Do Open Sound headphones have good sound quality even though they're open?
Do Open Sound headphones have good sound quality even though they're open?
Yes. Thanks to the directional sound system of Open Sound technology, audio is directed straight into your ears, minimizing sound leakage outwards. The result is a natural and immersive listening experience, with defined bass and crisp highs, without the need to seal the ear canal. Additionally, the microphone with ENC technology ensures clear calls even in environments with ambient noise.

Is the Curved-Fit design comfortable for prolonged use?
Absolutely. The Curved-Fit design of our open-ear headphones is engineered to conform to the shape of the ear without pressing on the ear canal, making them exceptionally comfortable for long sessions of sports, work, or daily use. By not entering the ear, they reduce auditory fatigue and are more hygienic than traditional in-ear models.
