Anytime. Anywhere. Active Noise Cancellation in the SPACE ONE headphones is tuned to preserve Hi-Fi integrity, blocking external ambient noise, without affecting the nuances and details that bring music to life. Iconic Porsche Design styling gives SPACE ONE a strong silhouette, while creating natural sonic plains full of crisp high-tones, lush mid-range, and tight bass. Intense. Precise. Exceptional. The full-range 40mm driver with KEF acoustic tuning generates clean, pure sound of the highest quality, as deluxe, memory-foam ear cushions support comfortable, long-term wear. With a full battery charge, 50 hours of active-noise-cancellation playtime is ensured.
