Updated HIFIMAN SUNDARA Planar Magnetic Headphones

HIFIMAN, founded by Dr. Fang Bian in 2007, is widely regarded as one of the leading manufacturers of high-performance headphones and portable audio products. The company is especially known for its critically-acclaimed Planar-Magnetic headphones that feature state-of-the-art driver technology. HIFIMAN also designs and manufactures world-class dynamic in-ear drivers, which have garnered awards and rave reviews.

The HIFIMAN SUNDARA, a new Planar Magnetic headphone, literally means "Beautiful" in Sanskrit and lives up to this description in every way. Featuring a frequency response of 6Hz to 75kHz, an impedance of 32Ω, and a sensitivity of 92dB, the SUNDARA weighs 342g and boasts a newly developed diaphragm that is 80% thinner than the HE400 series.

The all-metal headband and weight-spreading strap provide outstanding comfort, while the sleek and sumptuous matte black finish gives the SUNDARA a more fashion-conscious look. The new 3.5mm headphone connector enhances durability, replacing the previous 2.5mm connector used in prior models.

The SUNDARA's key features and benefits include the NEO "supernano" Diaphragm (NsD), which is 80% thinner than previous designs, resulting in a faster and more detailed response while retaining a lush musicality never before possible. The hybrid headband design, with its carefully crafted weight-dispersing strap, allows the headband to provide outstanding comfort.

The sleek, lightweight aluminum headband design keeps the SUNDARA strong, light, and urban-friendly. The new 3.5mm headphone connector offers enhanced durability compared to the previous 2.5mm connector.

Users are advised to allow for a "burn-in" period of approximately 150 hours to allow the headphones to reach their full audio potential. The 3.5mm headphone cable is user-changeable and replaceable, and a 6.35mm adapter is also included to enable use on outputs with a 6.35mm socket.

It is recommended to keep the SUNDARA at moderate listening levels to ensure long-term enjoyment of its audio quality. Touching the drivers should be avoided, as they do not require user maintenance and any contact may potentially damage the diaphragm.

Troubleshooting tips include addressing hissing, buzzing, or noise by gently removing any dust or hair on the driver without touching the diaphragm, and ensuring a proper audio source with adequate power to drive the planar headphones. If sound quality is not as expected, a break-in period of up to 150 hours may be required. In case of stopped operation or distortion, checking the DC voltage of the amplifier is crucial to ensure proper functioning.
