Immerse Yourself in Private Audio Heaven

Following on the heels of one of the most popular headphones of all time, the HIFIMAN Sundara Open-Back headphones, we are excited to introduce the new HIFIMAN Sundara Closed-Back Headphone

These headphones are designed to offer excellent isolation, blocking out external noise and preventing sound leakage, making them ideal for use in noisy environments or for private listening.

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. 

Additionally, the acoustically-invisible stealth magnets allow sound waves to pass through without causing interference, reducing wave diffraction turbulence and greatly minimizing distortion.

The HIFIMAN Sundara Closed-Back Headphone employs a diaphragm that measures less than two micrometres in thickness, allowing them to deliver exceptional detail and lifelike imaging that outshines other headphone models. 

This is due to the NEO Supernano diaphragm, the most critical factor in achieving superior detail retrieval in headphones. 

While most diaphragms are commonly made of plastic or cardboard, the Sundara's diaphragm is made of an ultra-thin material that allows for realistic detail reproduction, even when vibrating up to 20,000 times per second.
