Q: What devices are compatible with the BQEYZ C30 DAC Amp?
A: The BQEYZ C30 is compatible with any device featuring a USB-C port that supports USB audio output, including Android smartphones, tablets, laptops, and computers. It is plug-and-play — no drivers or software installation required for basic use.
Q: What is the benefit of the 4.4mm balanced output on the C30?
A: The 4.4mm balanced output provides a fully balanced audio signal path, which typically delivers a wider soundstage, improved channel separation, and a lower noise floor compared to a standard single-ended 3.5mm connection — ideal for audiophile-grade balanced headphone cables.
Q: Does the BQEYZ C30 require batteries or external power?
A: No. The C30 is bus-powered, meaning it draws power entirely from your source device through the USB-C connection. There are no batteries to charge or replace, making it a truly portable, always-ready audio solution.
Q: How does the 10-Band Parametric EQ work on the C30?
A: The 10-band PEQ allows you to adjust specific frequency bands across the 20Hz–20kHz audio spectrum, letting you boost or cut frequencies to compensate for headphone colorations or to match your personal listening preferences. It offers a level of fine-tuning rarely found in a device this compact.
