Hifiman Ananda BT R2R: The Enhanced Version of the Ananda BT Model

The Hifiman Ananda BT R2R represents a significant advancement in the realm of wireless audiophile headphones. It is an enhanced version of the original Ananda BT model, incorporating Hifiman’s latest technological innovations to offer uncompromised listening experiences for audiophiles on the go.

At the heart of the Ananda BT R2R is a planar magnetic transducer utilizing Hifiman’s NEO “supernano” Diaphragm (NsD) technology. This ultra-thin diaphragm, 80% thinner than previous generations, allows for a fast and precise response. It produces a detailed sound image with deep bass and a wide sound across the entire frequency range.

Advanced Acoustic Technology

The headphones also integrate Hifiman’s Stealth Magnet technology. The special shape of these magnets allows sound waves to pass through without interference, significantly reducing diffraction and turbulence. The result is a pure, precise, and wideband sound output.

Integrated R2R DAC

One of the main innovations of this version is the integration of an R2R DAC (digital-to-analog converter). This technology uses a resistor network and a new algorithm to optimize signal processing between the chip and peripheral components. This improves the signal-to-noise ratio, total harmonic distortion, and energy consumption.

Versatile Use

Although designed for wireless use, the Ananda BT R2R also offers a wired connection via USB. In this mode, it can function as an external USB DAC, supporting audio streams up to 24 bit / 192 kHz. This versatility allows users to enjoy optimal sound quality in all situations.

Ergonomic and Comfortable Design

The headphones feature an open design with a “window shade” grille that reduces sound reflections for increased clarity. Its hybrid headband ensures optimal comfort, even during long listening sessions. Weighing 469g, the Ananda BT R2R remains relatively light for a planar magnetic headphone of this caliber.

Practical Features

The Ananda BT R2R includes a quality microphone, ideal for phone calls and gaming. Its rechargeable battery offers up to 10 hours of playback, with a full charge time of approximately 2.7 hours. A single button controls power on/off, Bluetooth pairing, and call handling.
