## Long description

HERTZ adapter USB-C to 3.5mm jack AK291A, white is a compact audio adapter that converts a USB-C port into a standard 3.5 mm headphone jack. Designed for devices that lack a dedicated analog audio output, this plug-and-play adapter makes it possible to use wired headphones, headsets with microphone support, and other 3.5 mm audio accessories with smartphones, tablets and laptops that provide audio over USB-C. The white casing and minimalist form factor make the adapter unobtrusive and easy to carry in a pocket or bag.
Advantages
The adapter supports simple, reliable analog audio output without requiring drivers, providing immediate connectivity for headphones and external speakers. Its compact size and lightweight construction ensure convenient portability. The white finish offers a neutral aesthetic that pairs well with most devices. The AK291A is intended for everyday listening, voice calls and basic audio tasks where a 3.5 mm connector is required.
Suitable for
Connecting wired headphones to smartphones, tablets and laptops with USB-C only
Using headsets with inline microphones for voice calls and conferencing

How to use
Insert the USB-C end of the adapter into the device's USB-C port and plug the 3.5 mm headphone or headset connector into the adapter's jack. The adapter is plug-and-play: audio should switch automatically to the connected accessory for music playback and calls. If a headset with a microphone is used, check device audio settings to ensure the external microphone is selected when making calls or recording. When disconnecting, remove the adapter gently to avoid stress on the device port.
Usage recommendations
For reliable operation, use with devices that explicitly support audio over USB-C or support analog audio adapters. Avoid exposing the adapter to water or extreme temperatures, and store it in a protective case or pocket to prevent bending or debris ingress in the connectors.
