What to know before buying

Listing details to confirm

The listing's supported-device details are inconsistent: its title names iPhone 17 and Galaxy S25, while its detailed compatibility list names iPhone 16/15 and Galaxy models through S24, without confirming those title models. Call and control functions are also limited on some phones that already have a 3.5mm jack and on iPad Pro 2018. Customer feedback reports mixed call compatibility, durability, and connection retention, so these remain practical points to consider rather than confirmed outcomes for every unit.

Who is it for?

A good fit for

People who want to connect standard CTIA 3.5mm headphones or speakers to a compatible USB-C device.
Buyers who mainly need wired audio playback and can verify their device and headset combination.

Less suited to

People who need guaranteed microphone or call support across devices or with Apple 3.5mm EarPods.
Users with OMTP headsets or microphone-only TS or TRS devices.
