## Summary description

Retoo E405 is a compact adapter that connects a Lightning device to a 3.5 mm headphone jack and a USB‑C port. Designed for devices with Lightning connectors, it provides combined audio output via 3.5 mm and a USB‑C connection for charging or data passthrough where supported. Practical for listening with wired headphones while maintaining USB‑C connectivity.

## Long description

Retoo E405 Lightning to 3.5mm Jack and USB-C adapter is a compact white accessory that enables simultaneous connection of a 3.5 mm wired headset and a USB-C cable to devices with a Lightning port. The adapter provides a standard analog audio output via the 3.5 mm jack while exposing a USB-C port for charging or data passthrough on hosts that support accessory charging or audio routing. Its small form factor and plug-and-play operation make it suitable for travel and daily use when both audio and a wired power or data connection are needed.
Advantages
The adapter combines an analog headphone jack and a USB-C socket in a single Lightning-connected unit, allowing users to listen with wired headphones while keeping the device connected to USB-C power or compatible accessories. Its lightweight design and simple connection require no additional software, and the white finish matches many portable devices. The unit supports common 3.5 mm headsets and standard USB-C cables for broad compatibility where hardware support exists.
Suitable for
Listening to music or calls with a 3.5 mm wired headset while charging the device
Using wired headphones during long trips or in situations with limited Bluetooth connectivity
Connecting to car audio or portable speakers with a 3.5 mm AUX input while maintaining power via USB-C
Users who need a small, portable adapter for occasional wired-audio and USB-C passthrough
When it may not be suitable
This adapter requires a device with a Lightning connector and relies on the host device’s hardware and software to support simultaneous audio output and USB-C charging or data passthrough. Some Lightning devices or specific firmware versions may not route audio or power as expected, so full functionality cannot be guaranteed on all models. It is not a replacement for a dedicated multiport hub with additional features such as video output or multiple USB ports.
Key specifications
Connector A: Lightning (male)
Connector B1: 3.5 mm female headphone jack (analog audio output)
Connector B2: USB-C female (power delivery or data passthrough where supported)
Color: White
Form factor: Compact, lightweight adapter
How to use
Plug the Lightning end of the adapter into the Lightning port of your device. Insert a 3.5 mm headphone plug into the jack and connect a USB-C cable to the USB-C socket if you need to charge the device or connect a compatible USB-C accessory. The adapter functions without additional drivers; check device settings or manufacturer documentation if audio or charging behavior differs. Disconnect by gently removing cables and then the adapter from the device.
What to consider before purchase
Confirm your device has a Lightning port and supports simultaneous audio and USB-C passthrough functions
Ensure your wired headphones use a standard 3.5 mm plug
Check whether your use case requires additional features (e.g., multiple USB ports or video output) that this adapter does not provide
Be aware that compatibility may vary by device model and OS version
Usage recommendations
For reliable operation, use original or high-quality USB-C cables and standard 3.5 mm headphones. If you experience unexpected behavior, test the adapter with another compatible Lightning device to isolate whether the issue is device-specific. Avoid excessive bending of connected cables to prolong the adapter’s service life.
