The advanced magnet design featured in the HiFiMAN SUNDARA Closed-Back is acoustically transparent, dramatically reducing wave diffraction turbulence that typically degrades the integrity of the sound waves. The result is reduced distortion, yielding a purer, more harmonious sound that is demonstrably better than previous designs. Unlike the sound waves that are created by conventional magnets, the unique shape of stealth magnets enable soundwaves to pass through the magnet without generating interference.
