Listed as excellent cosmetic and working, this is priced very well at US$65 against a US$100 median and US$63 25th percentile for recent comparable USD listings. That lands it just above the lower quartile and comfortably below the market midpoint, so it reads as a solid buy rather than a bargain-bin shot in the dark.
The FC4 is a respected little dongle DAC because it gives you proper 3.5 mm and balanced 4.4 mm output in a pocketable package, making it a handy step-up for phones, laptops, and portable rigs. Clean condition matters here, since these are often used heavily on the go; if the cable and plugs are intact, this is the kind of straightforward, good-value piece that should earn its keep immediately.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
HiBy is a Chinese audio brand established in the early 2000s by Fanoble Meng and Rick Wong, two software engineers who built their expertise at a prominent Chinese audio manufacturer before founding the company. With over 15 years of specialization in portable audio, HiBy has evolved from a niche player into a recognized name in the digital audio player market, recently expanding its organizational structure to include HiBy Music and HiBy Digital as distinct product lines.
The brand's product portfolio centers on portable high-fidelity solutions, including Android-based digital audio players, USB DACs, headphone amplifiers, and earphones. HiBy is particularly known for its DAPs, which typically feature premium DAC chips from Cirrus Logic and support high-resolution audio formats including DSD and PCM up to 32-bit/768kHz. The company has recently introduced desktop-oriented products under the HiBy Digital sub-brand, including all-in-one audio hubs and complementary accessories, signaling a strategic expansion beyond portable listening.
HiBy occupies the accessible-to-mid-tier segment of the hi-fi market, positioning itself as a value-conscious alternative to premium brands while maintaining technical credibility. The brand appeals to enthusiasts seeking bit-perfect, high-resolution playback without flagship pricing, and has cultivated a reputation for thoughtful engineering and user-driven innovation. Recent product launches demonstrate HiBy's commitment to diversifying its ecosystem while maintaining focus on digital audio quality and practical design.
