Girftu USB-C to 3.5mm DAC Adapter 32-bit/384kHz

The Girftu JCALLY JM20MAX is a compact USB-C to 3.5mm DAC dongle that delivers high-resolution, low-noise audio using dual chips for richer, more detailed playback.

Designed for listeners who want studio-grade sound from phones, tablets, or laptops, the JM20MAX converts digital USB-C output into analog audio with support for 32-bit/384kHz PCM and DSD256. Its CS43131 DAC and SGM8262 amplifier work together to provide up to 195mW of output, while the aluminum housing and braided cable keep the unit durable and pocket-friendly. The adapter is plug-and-play across modern iOS and Android devices that use USB-C, so you can connect wired headphones without extra drivers.

How does the JM20MAX improve my headphone sound?

The JM20MAX replaces a device’s internal DAC and amplifier with higher-performance components to reduce noise and reveal musical detail. That results in clearer highs, fuller mids, and deeper, controlled bass compared with typical phone outputs.

• Dual-chip design: CS43131 DAC + SGM8262 amp for lower distortion
• Supports high-resolution formats: 32-bit/384kHz PCM and DSD256
• Up to 195mW output for better drive of common headphones
• Gold-plated 3.5mm connector to minimize signal loss

Will it work with my phone or tablet?

The JM20MAX is built for wide compatibility with USB-C devices. It operates as a standard USB audio class device so most modern phones, tablets, and computers will recognize it automatically—no app or driver installation needed.

• Compatible with USB-C iPhones and Android phones (Samsung, Pixel, OnePlus, etc.)
• Works with tablets and many laptops that support USB-C audio
• Plug-and-play: no drivers or settings required in most cases

How portable and durable is the JM20MAX for daily use?

The adapter combines a compact aluminum body with a braided cable to withstand daily handling while fitting easily in pockets or bags. Its light weight and short length make it unobtrusive for commuting, travel, or desk use.

• Lightweight: approximately 6.5 grams and ~110mm long
• Aluminum housing resists wear and improves thermal behavior
