HiBy W4 Portable Hi-Res DAC & Amplifier

Dual-Mode | Dual-DAC | Touchscreen | Wireless + Wired Freedom

The HiBy W4 Portable Hi-Res DAC & Amplifier is an all-purpose, next-generation audio gadget built for audiophiles who want uncompromised sound—anywhere, anytime. Designed as both a Bluetooth DAC/AMP and a USB DAC, the W4 lets you freely switch between wireless convenience and wired high-resolution performance, making it the perfect companion for smartphones, laptops, and car audio systems.

At its core, the W4 features dual Cirrus Logic CS43198 DAC chips, independently decoding left and right channels for superior channel separation, higher SNR, and a more immersive soundstage. With support for DSD512 and PCM up to 768kHz, femtosecond-grade oscillators, and powerful output of up to 475mW via the 4.4mm balanced port, the W4 effortlessly drives everything from sensitive IEMs to demanding planar headphones.

In Bluetooth mode, the Qualcomm QCC5181 decoding core with Bluetooth 5.4 ensures ultra-stable, low-latency, hi-res wireless playback. In USB mode, the dedicated UnCharge feature isolates power supply noise by running purely on the internal battery—even when connected to a phone—delivering cleaner, purer audio while saving smartphone battery life.

A rare highlight in this category is the 2-inch full-colour touchscreen, allowing intuitive control of playback, pairing, filters, and settings directly on the device. Album art display, NFC one-touch pairing, a detachable metal clip, MagSafe compatibility, and a 1500mAh battery make the HiBy W4 as stylish and practical as it is powerful.

Whether clipped to your outfit, used as a desktop USB DAC, or integrated into your car audio system, the HiBy W4 is built to redefine portable hi-res listening.
