YOUR BUYING COMPANION
Get the right fit for your setup.
Three useful checks before you order. Work through them at your own pace.
01Check compatibility and fit
Match plug gender, socket size, signal type and direction. A passive adapter does not add a digital converter, microphone function or device support that is not specified.
02Choose the right configuration
Review the pack, color and other options. The selected configuration and price identify what goes in your cart; the photograph does not establish pack quantity.
03Plan the first use
Read the setup and care guidance below. For a larger supply order, check one item against the actual fit and intended task before distributing the rest.
Use these checkboxes to track your review. Confirm the selected contents and any fitting or care requirements before ordering.
WHAT IT IS · HOW IT WORKS
Make the connection your setup actually needs.
Connect a compatible 3.5 mm audio plug to equipment with a 2.5 mm socket. Match both connector size and audio wiring before use; this is a physical audio adapter.
A 3.5 mm socket for the accessory
The female end accepts the matching 3.5 mm plug from your audio accessory.
A 2.5 mm plug for the device
The male end fits compatible equipment with a 2.5 mm audio socket. Check your equipment manual for the required wiring.
Check the actual audio setup
Start at a low volume and test playback. Microphone function depends on the wiring and device support; connector size alone does not establish it.

How to use it.

Map the connection
Identify the device port and the accessory plug. Note which end is male or female and whether audio, microphone, data or charging is required.
- 2
Match the exact option
Check the selected connector arrangement. Read the device or equipment instructions for the required signal and direction. Matching connector shapes alone do not establish support for audio, microphone input, charging or USB data.

Connect and select the device
Seat the plugs gently and select the intended input or output in your device or application when required.
- 4
Test the required functions
Check playback and, if applicable, microphone input, charging or data transfer on the actual equipment.

BEFORE YOU ORDER
Useful answers.
What is included in my order?
One audio adapter. Other equipment shown in setup illustrations is not included.
Will any matching plug work?
No. Physical fit does not establish signal compatibility. Check TRS/TRRS wiring, digital audio support and the required input/output arrangement.
Does this work in both directions?
Use only the direction and function specified for the selected adapter.
What if the microphone does not work?
Check port wiring, input selection and application permissions. A headphone-only output cannot accept microphone input.
How do I confirm a larger order?
Choose the required configuration and pack quantity, then review the cart. Contact MaeLine Corp before ordering if you need help with fit, set contents or larger quantities.
