The KZ AM02 is a compact USB-C DAC amplifier designed to connect wired 3.5mm earphones, IEMs and headphones to compatible USB-C devices. It combines a high-performance DAC, 27mW output at 32Ω, up to 96kHz/24-bit decoding and four built-in EQ modes, including dedicated gaming modes for positional detail and footsteps. Its aluminum alloy body and Kevlar-braided cable make it practical for everyday portable use.
KZ AM02 Portable DAC Amplifier
If your phone, tablet or laptop uses USB-C but your preferred earphones or headphones still use a 3.5mm plug, the KZ AM02 provides a compact way to bridge the two. It works as a USB-C DAC and headphone amplifier, converting digital audio from a compatible source into analog audio through its 3.5mm output. KZ specifies support for USB-C devices with OTG functionality.
Four EQ Modes for Music and Gaming
One of the main reasons to choose the AM02 over a basic USB-C-to-3.5mm adapter is its built-in four-stage EQ system. The EQ can be changed directly from the device rather than relying on an app or computer software.
The four modes are:
-
Music Balanced Mode – a balanced presentation of bass, mids and treble for general music listening.
-
Bass Boost Mode – emphasizes the low frequencies for a fuller bass response.
-
Standard Gaming Mode – tuned around positional cues, gunshots and layered details for gaming.
-
Immersive Gaming Mode (Deep Dive Mode) – emphasizes footsteps, gunfire and environmental details for a more immersive gaming presentation.
High-Resolution DAC and Amplification
KZ lists DAC decoding capability of up to 96kHz/24-bit, with a specified 105dB SNR, 105dB DNR, -85dB THD+N and frequency response of 10Hz–44kHz. The rated output power is 27mW at 32Ω, while KZ specifies an impedance range of 16Ω or higher.
These specifications make the AM02 particularly relevant for portable IEMs and other relatively easy-to-drive wired headphones. Actual volume and sound results will still depend on the headphones or IEMs being used and the source device.
Compact Aluminum Build
The AM02 uses an aluminum alloy housing with a frosted finish. KZ states that the housing is CNC-machined and designed to resist fingerprints while providing a durable, compact construction.
The attached cable uses a high-density Kevlar braided outer layer with a reinforced core. This construction is intended to improve resistance to everyday bending, pulling and wear.
USB-C Connectivity
The AM02 uses USB Type-C as its input and provides a 3.5mm audio output. KZ describes it as plug-and-play for compatible USB-C devices, including smartphones, tablets and laptops, provided the USB-C port supports OTG functionality.
This makes it useful for modern devices that no longer include a traditional 3.5mm headphone jack while allowing the customer to continue using wired audio equipment.
No Battery or Charging Required
The KZ AM02 is a wired USB DAC/amp rather than a wireless or battery-powered audio device. KZ specifies a USB-C input and does not list an internal battery or charging specification. It therefore receives its operating power from the connected USB-C source.
Battery capacity, charging time and battery life are not applicable to this model.
