The HiBy R6 Pro II: A New Addition to the Android Digital Audio Players Lineup

by Paul Dmitryev

The HiBy R6 Pro II, a new addition to the company’s Android Digital Audio Players (DAPs) lineup, is now available for purchase. Priced at $750, this latest model has generated interest for its updated features and design philosophy. HiBy, a well-regarded brand in the audio market, continues its tradition of offering quality devices that cater to a wide range of listeners.

The R6 Pro II represents a significant shift in HiBy’s design philosophy, and the company has focused on enhancing the sound quality rather than solely increasing the output power. That ideas lead to the introduction of the All-In architecture, which aims to maximize the performance of the dual AK4499EX DACs while balancing power consumption and portability. The All-In architecture allows each output of the dual AK4499EX DACs to be equipped with an I/V conversion circuit, ensuring the DACs reach their full potential. This design also results in faster response speed and improved sound density. However, this architecture leads to complex circuitry, increased power consumption, and the need for precise component matching.

As a result of these design changes, the R6 Pro II’s battery life is lower than its predecessor, mainly when using Class A amplification mode. However, HiBy has always provided conservative battery life estimates so that actual usage may differ. The company believes that the benefits of the new All-In architecture outweigh the decrease in output power and battery life, as it allows for a more refined audio experience that caters to the primary use case of portable players.

The company also emphasizes the difference between power and driving force. Generally, only high-impedance, full-size headphones require high-voltage output. By focusing on control and driving force for low-impedance in-ear earphones, which are the primary use case for portable players, HiBy aims to deliver a more faithful sound reproduction. This approach aligns with the company’s future design philosophy for DAPs.

The R6 Pro II showcases a revamped design, featuring bold asymmetrical lines that create visually appealing slanted surfaces while maintaining grip-friendly ergonomics. The device is available in two color options: purple and black — and caters to users’ aesthetic preferences. The player measures 147.45 x 75.2 x 15mm and weighs 285g, making it a portable companion for on-the-go audiophiles. A notable design element is the new back panel, which features an abstract artistic representation of “aluminum waves crashing against a golden shore beneath a starry carbon sky.” This fresh design approach adds a touch of elegance and sophistication to the R6 Pro II.
