Manufacturer description
The Oxsubor AUX to USB Adapter is a narrow-purpose 3.5mm male to USB 2.0 female converter built for one job: feeding MP3 files from a flash drive into a car stereo that has an AUX-in port with built-in MP3 decoding. Plug the 3.5mm end into your dash, load a USB 2.0 drive with MP3 files, and the head unit handles playback. Read the compatibility rules before you buy, because they are strict. Your car radio must decode MP3 through the AUX port on its own; a passive AUX input that only accepts line-level audio will not work. The drive itself must be USB 2.0, under 8GB, and hold MP3 files only…
SpecPicks Verdict
SpecPicks scored Oxsubor AUX to USB Adapter using a rating × review-volume × price-fit model applied to published specs and reviews across the joysticks & game port category. Oxsubor's joysticks & game port lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for joysticks & game port of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Will this adapter work with my car?
Only if your car stereo has a 3.5mm AUX-in port and decodes MP3 files through it. Passive AUX ports that accept audio input only will not work with this adapter. Some factory radios do not support the function, so check your head unit before buying.
What kind of USB drive do I need?
A USB 2.0 flash drive with a capacity under 8GB. USB 3.0 drives and other versions are not supported. Store MP3 music files only, with no videos, no folders, and no other file types on the drive.
Can I use this to connect headphones or a speaker?
No. Oxsubor states the cable is not compatible with headsets, speakers, phones, computers, cameras, microphones, monitors, game consoles, or MP3 players. It does not transmit audio or data for those devices.
What is included and is there a warranty?
You get one AUX to USB adapter cable. Oxsubor lists a 24-month replacement warranty and lifetime support, and asks that you contact them if the adapter does not work with your vehicle.
