MTAKYI Lightning/USB-C to 3.5mm Audio OTG Adapter

MTAKYI's compact Lightning/USB-C to 3.5mm & Type-C adapter combines an external DAC, OTG camera support, and a pass-through charging port so you can listen with wired headphones and use USB peripherals at the same time.

This travel-ready adapter converts a single Lightning or USB-C phone or tablet port into a 3.5mm audio jack, a Type-C charging socket, and a USB OTG host connector. It's engineered with a built-in DAC chip for improved audio clarity and supports common headset wiring standards, while offering plug-and-play convenience—no apps required. The adapter is a practical accessory for devices that lack a dedicated headphone port or for users who need to connect cameras, keyboards, thumb drives, or wired earphones while charging.

How does this adapter handle audio and charging simultaneously?

The adapter routes digital audio through its integrated DAC to the 3.5mm output while providing a separate Type-C charging inlet so you can power your device. It does not allow two different wired headsets to play concurrently; the Type-C port is for power or Type-C headphones only.

• Integrated DAC improves sound from digital-only devices.
• 3.5mm female jack supports CTIA and OMTP wiring standards.
• Separate Type-C port accepts charging while audio plays.
• Not designed to mix two wired headphone outputs simultaneously.

Which devices and headphones will this adapter work with?

The adapter is made to be broadly compatible: Lightning-equipped iPhones and USB-C phones, tablets, and computers are supported. It works with standard 3.5mm wired headsets and many Type-C headphones, plus a long list of Android and Apple models is supported for both audio and OTG functions.

• Compatible with iPhone 7 through iPhone 15 series and many iPad models.
• Works with Android devices including Samsung Galaxy, Pixel, Huawei, and more.
• Supports Type-C headphones and 3.5mm wired earphones (single output at a time).
• Also suitable for MacBook, Surface, and other USB-C laptops for audio or OTG use.

What OTG and USB functions can I expect from this adapter?

Beyond audio and charging, the adapter acts as a USB On-The-Go hub to connect peripherals like cameras, flash drives, and input devices. File transfers, peripheral control, and camera import are supported at practical speeds depending on host device capabilities.

• Supports USB OTG peripherals: keyboards, mice, USB microphones, and cameras.
• File transfer support for common formats (MP3, MP4, JPEG, PDF, Office files).
• Transfer bandwidth up to typical USB rates (host-device dependent).
• Plug-and-play with no additional software installation required.

How durable and portable is the MTAKYI adapter for travel?

Designed for everyday carry, the adapter is small, lightweight, and built to slip into pockets or bags without adding bulk. The housing and connector fit a travel use case while aiming for reliable repeated connections on the road.

• Compact form factor that fits in purses, pockets, and backpacks.
• Lightweight construction for easy portability on trips.
