HIFIMAN – ANANDA BT Wireless PlanarOpenback Headphone
Ananda-BT 2024 Open-back planar bluetooth headphone
When we first introduced the ANANDA-BT five years ago, it represented the best of both available Bluetooth technologies and features unique to HIFIMAN,” says Dr. Fang Bian, Founder and CEO, HIFIMAN. “This new version of a HIFIMAN classic takes the best of the original and adds several of our most recent developments to create a new standard in high-fidelity wireless audio.”
The rechargeable ANANDA-BT features HIFIMAN’s R2R DAC technology. A chip composed of an array of resistors with a new algorithm reduces power handling between the chip and peripheral components. As a result, signal-to-noise ratio, total harmonic distortion, and energy consumption are at their most efficient and cost-effective.
The audiophile-grade HIFIMAN ANANDA-BT, with HD Bluetooth technology, offers up to 24bit / 192khz (USB) , 24bit / 96khz (Bluetooth), lossless audio streaming. With full support for high-resolution protocols including LDAC™, aptX™ and aptX-HD™, the ANANDA-BT is compatible with most high-definition playback devices on the market, ensuring excellent audio signal transmission for outstanding sonics. Of course the Ananda-BT holds Stealth Magnet Technology and its Neo supernano technology for the diaphragm.
- Acoustic Design: Open-back, asymmetrical ear cups featuring HIFIMAN’s Stealth Magnet design (which reduces wave diffraction turbulence) and the NEO “supernano” Diaphragm for ultra-fast transient responses.
- Audio Architecture: Built-in Hymalaya R2R DAC using custom FPGA algorithms to dramatically improve power efficiency while delivering smooth, organic analog-like decoding.
- Frequency Response: 8Hz – 55kHz .
- Impedance & Sensitivity: 25Ω / 103dB.
- Weight: 454g (approx. 1 lb).
- Battery & Power: Up to 10 hours of playback with a charging time of roughly 2.7 hours via USB-C
