When HiFiMAN introduced the brand new Deva Pro Wireless headphones and HIMALAYA R2R 24-bit Dacian Module, we suspected there was more to the story. Nobody spends that kind of money developing a new high-resolution DAC module for a single pair of headphones.
The HIMALAYA is a precision, 24-bit DAC (Digital-to-Analog Converter) that relies on R2R architecture, striking for its FPGA (Field Programmable Gate Array) chip composed of a series of resistors. The HIMALAYA architecture is flexible to meet different size requirements based on the product circuit board.
The DAC was then integrated into the HiFiMAN Bluemini R2R dongle that can be used to turn passive headphones into powered wireless models.
Should you decide to spend the extra money, the brand new HiFiMAN HE-R9 can be converted into a pair of wireless headphones that make them so much more versatile.
The new HE-R9 (SRP: $ 599) features high-sensitivity features thanks to HIFIMAN’s use of rare earth magnets and the company’s classic Topology aperture for detailed high-frequency response up to 35Hz.
By applying nanoscale particles to the diaphragm in a variety of patterns and layers, high-level optimization takes place, which has a positive effect on the sound characteristics.
“We originally introduced the Topology Diaphragm in a dynamic closed-back design last year in our reference R10D dynamic driver headphones,” said dr. Fang Bian, founder and CEO, HIFIMAN Electronics, said. “This latest version applies a similar design in a headphone that comes in at a lower price point, but with sonic features that are almost comparable to its older sibling.”
The HE-R9 is designed for extended listening sessions. The headband features high-grade memory foam for maximum comfort and elasticity. The headband skeleton is made of steel that is lightweight and strong. On the outside, genuine leather gives the R9 a soft and elegant look. Newly designed ear cups are great for substantial volume and exceptional overall acoustics.
For compatibility with the highest range of sources, the HE-R9’s socket accommodates both double-sided 3.5 mm and single-sided balanced cables.
The addition of HIFIMAN’s Bluemini R2R dongle * turns the R9 into a high-resolution wireless headphone.
