With their closed-back design, the HIFIMAN Sundara Closed-Back headphones offer excellent isolation, blocking out external noise and preventing sound leakage, making them ideal for use in noisy environments or for private listening. 

Planar magnetic design 

Unlike dynamic driver headphones, which use a small diaphragm attached to a coil of wire, the Sundara's planar magnetic drivers utilize a thin, lightweight diaphragm that is driven by a series of magnets placed on either side. This innovative design results in a wider frequency response range, faster and more accurate sound, and significantly reduced distortion.

Acoustically-invisible stealth magnets

What makes the Sundara Closed-Back headphones different from other headphones on the market is their use of a uniquely-shaped magnet that permits sound waves to pass through without causing interference. This ingenious design feature reduces wave diffraction turbulence and greatly minimizes distortion. 

NEO Supernano diaphragm

The diaphragm's performance is the most critical factor in achieving superior detail retrieval in headphones. Most diaphragms, which are commonly made of plastic or cardboard, face challenges in reproducing realistic detail as they must vibrate up to 20,000 times per second. However, the HIFIMAN Sundara Closed-Back headphones employ a diaphragm that measures less than two micrometres in thickness, allowing them to deliver exceptional detail and lifelike imaging that outshines other headphone models.
