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.

BEFORE YOU ORDER
Useful answers.
What is included in my order?
The selected product or accessory set. Check the stated components and option before ordering. Other equipment shown in setup illustrations is not included unless expressly listed.
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.
