Audio Adapter Satechi Type-C to 3.5mm — Satechi Hoco LS33

Satechi Hoco LS33 is a compact Type-C to 3.5mm audio adapter that enables devices with USB-C ports to connect to standard 3.5mm headphones and external speakers. The adapter provides a plug-and-play connection for audio output and supports hands-free calls on compatible smartphones, tablets and laptops that lack a dedicated headphone jack. Its small form factor and simple design make it suitable for portable use and quick audio conversion without additional software.

Advantages

The adapter converts a USB-C port to a 3.5mm analog audio output, allowing use of existing wired headphones and in-line microphone headsets. It requires no drivers or setup on most devices and supports inline remote controls where hardware compatibility exists. The compact cable and molded connector deliver a minimal footprint in pockets or bags while maintaining a straightforward connection between device and audio accessory.

Suitable for

• Smartphones and tablets without a dedicated 3.5mm headphone jack
• Laptops and ultrabooks with USB-C audio-capable ports
• Connecting wired headphones, earphones and portable speakers
• Hands-free calls using headsets with inline microphones (when the device supports analog mic input)

When it may not be suitable

The adapter provides analog audio conversion and may not support advanced digital audio features such as high-resolution audio over USB-C or device-specific digital signal processing. It may not function with devices whose USB-C ports do not expose analog audio or require a manufacturer-specific adapter. Compatibility with in-line remote controls and microphones depends on the host device and headset wiring standards, so functionality is not guaranteed for all combinations.

Key specifications

• Connector: USB Type-C (male) to 3.5mm TRS/TRRS (female)
• Function: Analog audio output and headset microphone pass-through where supported
• Compatibility: Works with devices that support USB-C analog audio output
• Design: Compact adapter with short cable and molded connectors for portability
• Plug-and-play: No driver installation required on most platforms

How to use

Insert the USB-C connector of the Satechi Hoco LS33 into the device's USB-C port. Plug a 3.5mm headphone or speaker jack into the female 3.5mm socket. Audio should route automatically to the connected headphones or speakers. For headsets with an inline microphone, test call functionality to confirm that the microphone and any inline controls operate with your device. If audio does not route, check device settings for output selection and verify that the host port supports analog audio over USB-C.

What to consider before purchase

• Confirm your device's USB-C port supports analog audio output (not all USB-C ports do).
• Check whether your wired headset uses TRS or TRRS wiring if you require microphone or remote control support.
• Be aware that advanced digital audio features or higher-than-analog quality are not provided by an analog adapter.

Usage recommendations

For reliable operation, use the adapter with devices known to support USB-C analog audio and test headset microphone and remote control functions before extended use. Store the adapter in a protective pouch when carried with other accessories to avoid cable strain and connector wear.
