JCALLY AP7 Portable DAC & Headphone Amplifier With Type C To 3.5mm

JCALLY AP7 Portable Type-C DAC Amplifier

The JCALLY AP7 Portable DAC Amplifier turns any Type-C device into a high-resolution audio source. Built around the AK4377ECB DAC chip, it decodes PCM audio up to 32-bit/384kHz and DSD128 over DoP, delivering studio-grade clarity that standard phone or laptop audio output can't match.

Housed in a one-piece CNC aluminum body, the AP7 is small enough to carry daily while still driving demanding headphones — it's rated for headphones up to 600 Ohm impedance and puts out 70mW through its single-ended 3.5mm output. A sampling rate indicator light shows the format of whatever you're playing in real time.

Since it draws power directly from your connected device with no internal battery, the AP7 is ready to use the moment you plug it in — no charging, pairing, or setup required.

Key Features

• AK4377ECB DAC Chip: A dedicated high-performance decoder chip processes audio outside your device's internal circuitry, delivering cleaner, more detailed sound with minimal distortion.

• Hi-Res PCM & DSD128 Support: Decodes PCM up to 32-bit/384kHz and native DSD128 over DoP, giving audiophiles studio-quality playback from digital sources.

• One-Piece CNC Aluminum Body: A precision-machined aluminum shell offers a sturdier, more refined build than typical molded or welded dongle amps.

• Drives Up to 600 Ohm Headphones: With 70mW of output power, the AP7 can power a wide range of high-impedance headphones and IEMs cleanly.

• Sampling Rate Indicator Light: Changes color based on the audio format being played, so you always know what resolution you're listening at.

• No Battery, No Setup: Powered entirely through USB-C, the AP7 works instantly with no charging or app configuration needed.

• Broad OS Compatibility: Works with Windows 7/8/10/11, Android, macOS, iOS, and iPadOS without extra drivers.

Why Choose the JCALLY AP7 DAC Amplifier

Most phones and laptops compress or limit their internal audio processing, which flattens detail and dynamic range. The AP7 bypasses that limitation with a dedicated AK4377ECB DAC chip capable of true hi-res decoding, while its aluminum build and compact size mean it's easy to carry as a daily audio upgrade rather than a bulky desktop unit. For anyone who wants noticeably better sound from wired headphones without investing in a full desktop DAC/amp stack, the AP7 is a practical, portable step up.
