HiBy W4 is an all-in-one portable Hi-Fi solution that seamlessly switches between Bluetooth receiver mode and USB audio mode. Whether your music source is wireless or wired, W4 delivers powerful headphone amplification and uncompromising sound quality in a single compact device—perfect for everyday carry.
A dedicated UnCharge lever allows W4 to run entirely on its internal battery even when connected via USB. This innovative design reduces background noise and phase interference from external power sources, resulting in purer sound while also minimizing power draw from your smartphone or computer.
Unlike traditional dongles or Bluetooth receivers, W4 features a 2-inch color touchscreen for intuitive control. Playback, pairing, filters, and system settings can be accessed directly with simple taps, delivering a uniquely user-friendly experience in a portable Hi-Fi device.
In Bluetooth mode, W4 supports album art display, giving you a clear visual of track information while enhancing emotional engagement during listening sessions.
Powered by the flagship Qualcomm QCC5181 Bluetooth chip, W4 supports Bluetooth 5.4 for faster pairing, stronger stability, and improved resistance to interference. Advanced low-energy Bluetooth audio technology delivers higher sound quality without increasing power consumption—ideal for music, calls, and gaming.
HiBy W4 supports Snapdragon Sound and all major high-bitrate Bluetooth codecs, including aptX Adaptive, aptX Lossless, aptX HD, aptX, LDAC, AAC, and SBC. Enjoy high-resolution wireless audio up to 24bit/96kHz across Android, iOS, and Windows platforms.
W4 integrates dual Cirrus Logic CS43198 DAC chips, independently decoding left and right channels. This fully balanced design significantly improves SNR and channel separation, delivering cleaner transients, deeper bass impact, richer vocals, and enhanced spatial imaging.
Dual independent femtosecond-grade oscillators (45.1584MHz and 49.152MHz) ensure ultra-low jitter performance across both 44.1x and 48x sampling families, preserving timing accuracy and faithfully reproducing the original recording.
Equipped with both 3.5mm single-ended and 4.4mm balanced outputs, W4 delivers up to 475mW of driving power, effortlessly handling dynamic, balanced armature, hybrid, and planar IEMs and headphones.
The built-in 1500mAh battery provides up to 6 hours of continuous wireless playback. W4 supports playback while charging, allowing it to function as a wired DAC at home and a wireless Hi-Fi device on the go.
Featuring a bold, fashion-forward color-glitch design, W4 blends audio performance with modern aesthetics. The detachable metal clip allows secure wearing on clothing or bags and can be removed for flat dongle use with MagSafe-compatible accessories.
NFC one-touch pairing simplifies Bluetooth connections. Car audio optimized mode enables W4 to power on/off with your vehicle and reconnect automatically, creating a seamless lossless in-car audio experience.
