Syncwire Headphone Extension Cable, 3.5 mm Male to Female, 3.3 ft
A braided 3.5 mm extension with a slim step-down plug. Sits between a thick-cased phone and an aux cord so the cord's fatter plug never has to reach the jack, and adds 3.3 ft of reach. Store price checked 2026-11-06.

Caveats
- It is an extension, not an aux cord: you still need a male-to-male cable or headphones.
- Every extra joint is a possible spot for crackle; keep the plugs clean.
