The Ananda Nano provides a massive sonic upgrade. The Nanometer Thickness Diaphragm at its core is based on the famous Susvara design - resulting in much lower distortion, higher transient response, and double improvement of dynamics and details. Planar Sounds Better Since the conductor layer (voice coil) on the diaphragm of the planar headphone is evenly distributed on the surface of the diaphragm, the electromagnetic force that drives the diaphragm to vibrate and produce sound acts much more uniformly than the voice cool acts on the surface of the cone-type diaphragm of the dynamic headphone. Ultimately, the phase distortion is much lower, the spatial information of the sound reproduction suffers less loss than dynamic headphones, while providing a much larger sound stage and better positioning. The result? Ananda Nano has a wide frequency range - 5Hz to 55kHz. The three-dimensional sound field wraps around the listener’s ears, with the positioning and imaging of musical instruments are as precise as if experienced in a live performance. Acoustically Invisible Stealth Magnet Unlike the sound waves created by a conventional magnet, the special shape of Stealth Magnets enables the waves to pass through the magnets without generation interference. HIFIMAN’s advanced magnet design is acoustically transparent, dramatically reducing wave diffraction turbulence that degrades the integrity of the sound waves. The reduced distortion yields pure sonic output that is accurate and full-range. Portable Device, Ready to Drive High sensitivity that allows use with virtually any smartphone or portable audio device. Low distortion and amazing sound quality.
