USB c to 3.5mm Headphone and Charger Adapter,2 in-1 USB C PD 3.0 Charging Port to Aux Audio Jack and Fast Charging Dongle Cable Cord (2 Ports-Gray)

Like most modern smart phones, mine only has a single USB-C 'charging' connector, and no place to plug in a set of headphones or an AUX cable to an amplifier or the AUX input of a car stereo. Since I listen to audio books when I drive, especially to occupy myself on long drives associated with vacation trips, I rely on being able to sync/connect my smart phone with a rental car's stereo using Bluetooth wireless.On two recent trips where I had to rent a car at an airport, I ended up with a Chevy Equinox, both of which steadfastly refused to 'play nice' with my smart phone over Bluetooth. They only wanted to connect to Apple phones, and my Android phone was apparently not welcome. Luckily, for many years I always bring along an AUX cable which allows plugging a phone's headphone output to the car's AUX input. But only too late I remembered that my new phone does not have a headphone output. I was able to pick up a small 'USB-C to headphone' adapter at a Walgreens drug store I was driving past, and that got me my desired phone-to-AUX connection, but now the phone was depleting its battery charge on the long drive and even though I had along my car-power to USB-C charger cord, I could not plug it into the phone at the same time as the new adapter. So, I ended up leaving the phone plugged into car power via the charging cable, while listening to my audio book via the phone's tinny little speaker, just barely adequate due to road noise and such.I purchased this "USB-C to 3.5mm Headphone and Charger Adapter", which does the same thing as the little adapter from Walgreens, while also adding another USB-C connector for plugging in my phone's charger cord at the same time. I have tested it on my own car at home, and it works fine with my Android phone, and audio quality is just fine, and I verified that this adapter does allow me to charge the phone through it while listening.There is some information about this device allowing volume control, but there was no manual of guide with it and I don't see how to use that feature, if it actually has it.One caveat I noticed when testing this product with my Android phone and my own car; at first, there was no sound from the car's speakers even when playing my audio book. It seemed that the book was playing through the phone's little speaker and NOT outputting an audio signal via the USB-C connector. I had to go into my phone's settings and turn off the Bluetooth, at which point this product was able to start performing its function. The adapter I bought from Walgreens did not have this issue.Note: If you want to use this product in the way I described above, you will also need to have a suitable AUX extension cable, with the 3.5mm stereo phone plug at each end (one end plugs into the car's AUX input jack, and the other end plugs into the 'headphone' output jack of this product. I suggest that the cable be at least 3 feet long.If you just want to plug a pair of headphones into this product, you don't need an AUX extension cable.This product's 'headphone' output is suitable for both actual headphone use and also for the AUX type connection to a car's AUX input, or a computer's sound card 'line in' jack, etc.

Works great so far! Allows me to both charge my Google Pixel android and play music from my phone through the jack AT THE SAME TIME!The previous model I bought could only so one of the other at once... Lame.

Great I love the color and it works really well and good build quality

Update: Seller refunded the purchase price and is sending a replacement adapter. Hopefully the replacement works this time.Adapter stopped working after less than two weeks. The troubleshooting process was lengthy then the 30 day return window expired.

Works great on quest 3s

I'm still old school when it comes to using a 3.5mm audio jack in my car and this is a saver when it comes to charging my phone and using a 3.5mm at the same time. It plugs in easily, fits nice and snug on all ports, and the sound is still the same. It has quality that rivals Anker and you can feel that it's very similar.

Works for awhile, but then one ear phone will not work. Sometimes no sound and I have to wiggle and move cords.

Will not charge and play audio at the same time. That was the reason that i bought it in the first place to listen to audio while charging my cell phone.
