JCALLY SP7 High-Resolution USB-C to 3.5mm DAC Adapter with CX31993 Chip

JCALLY SP7 USB-C to 3.5mm Portable DAC with CX31993 Chip

The JCALLY SP7 is a compact USB-C to 3.5mm portable DAC built around the high-performance CX31993 chip, designed for anyone who wants better sound from a phone, laptop, or tablet without a headphone jack. It converts digital audio into a clean analog signal, supporting studio-grade 32-bit/384kHz PCM playback and a 117dB signal-to-noise ratio for noticeably clearer, more detailed audio.

Because it's plug and play with no driver installation required, the SP7 works the moment you connect it — ideal for daily commutes, late-night listening, or quick use during calls and meetings. Its full metal housing and 160mm cable keep it durable and travel-friendly, so it fits easily in a pocket or laptop bag alongside your other USB-C DAC accessories.

Whether you're upgrading from a phone's built-in audio or looking for a reliable, small-footprint DAC dongle, the JCALLY SP7 offers a simple way to get high-resolution sound without carrying a separate DAC/amp unit.

Key Features

• CX31993 DAC Chip: Handles digital-to-analog conversion with precision, giving you a noticeably cleaner and more accurate sound compared to a phone's stock audio output.

• 32-bit / 384kHz PCM Support: Plays high-resolution audio files at their full quality, so tracks sound closer to how the artist intended.
