Why it may suit you
Practical benefits based on documented specifications.
HiFi sound quality
Built-in smart DAC digital-to-analog converter delivers studio-grade audio through any standard wired headphones. No compression, no Bluetooth latency — just pure, uncompressed sound that matches the original recording.
Multi-function connectivity
Designed to extend your device’s connectivity while maintaining signal integrity across all connected accessories.
Premium aluminum alloy construction
The precision-machined aluminum alloy housing provides dual benefits: it dissipates heat efficiently (preventing the warmth many plastic adapters develop) and shields internal components from electromagnetic interference for cleaner audio and data transmission. Gold-plated contacts ensure long-lasting, corrosion-free connections.

Common buying questions
Clear answers to important compatibility questions.
Does it support microphone input for calls?
Yes. This adapter includes built-in microphone and in-line control circuitry, allowing you to take phone calls, adjust volume, and activate Siri or Google Assistant directly from the inline module — no need to touch your phone.
Is the sound quality better than Bluetooth?
HiFi-grade audio through a wired 3.5mm connection delivers significantly higher fidelity than Bluetooth at any bitrate. You get full dynamic range, stereo separation, and zero latency — ideal for music production monitoring or audiophile listening on the go.
Will it work on all USB-C phones and tablets?
Yes. Any device with a USB-C port that supports audio-out (which is nearly all modern smartphones, tablets and laptops) will work with this adapter immediately upon plugging in.
Does it generate heat during normal use?
Minimal warmth may be felt after extended use — this is normal for any active DAC-based adapter. The aluminum alloy body actively dissipates this heat to prevent overheating, which is an advantage over plastic-bodied adapters.
