High-Resolution Audio, Wherever You Go

The KZ AM03 is more than a standard USB-C audio adapter. Its built-in DAC converts digital audio with greater clarity and precision, allowing you to connect your favorite 3.5mm earphones or headphones to compatible USB-C devices.

Supporting audio decoding up to 24-bit/96kHz, the AM03 delivers detailed sound, clean separation and a more immersive listening experience for music, movies and gaming. 

Four Selectable Sound Modes

A dedicated sound adjustment button lets you switch between four carefully designed listening profiles:

Balanced Music Mode
A natural balance of bass, mids and treble for everyday listening and a wide range of music genres.

Bass Boost Mode
Adds greater weight and impact to low frequencies while maintaining clear instrument definition.

Standard Gaming Mode
Improves positional detail and enhances important in-game sounds for a clearer and more precise gaming experience.

Immersive Gaming Mode
Emphasizes footsteps, environmental details and action effects for a more engaging sense of space.

The integrated multiband tuning system adjusts the tonal balance directly through the adapter, so you can quickly select the profile that best matches your content. 

Dedicated DAC for Cleaner, More Detailed Sound

The AM03 uses an independent digital-to-analog conversion system designed to improve audio resolution and preserve subtle details that may be lost with basic passive adapters.

With a signal-to-noise ratio and dynamic range of 105dB, plus a rated output of 27mW at 32Ω, it provides efficient and controlled performance with compatible earphones and headphones rated at 16Ω or above. 

Convenient L-Shaped USB-C Design

The low-profile, right-angle USB-C connector sits closely against your device, reducing obstruction while holding a phone horizontally. This makes the AM03 especially practical for mobile gaming, video playback and everyday portable use. 

Premium Aluminum Construction

Both connector housings feature an integrated, CNC-machined aluminum-alloy shell with a finely sandblasted finish. The result is a lightweight, refined design with improved resistance to everyday scratches and wear. 

Reinforced Braided Cable

The short cable uses a high-strength Kevlar-braided outer layer designed to withstand pulling, bending and repeated daily use. According to KZ laboratory testing, the cable endured more than 20,000 bending cycles. 

Plug-and-Play Compatibility

Connect the USB-C plug to a compatible device, attach your 3.5mm earphones or headphones and start listening—no additional setup is required.

The AM03 is designed for USB-C smartphones, tablets, laptops and other devices that support digital audio through USB OTG. Device compatibility may vary, so confirm that your USB-C port supports OTG audio output before purchasing.
