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)

Works good my phone even noticed output of the dac in it . I'm using old school style to connect to tape adapter in my beloved old Lexus and sounds amazing way better than any fm transmitter at any price range

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.

Very useful adapter. Since the newer iPads come with USB-C port and no audio jack, I assume it’s expected that everyone uses wireless buds. I have both and sometimes prefer having the cabled earphones (like when you’re on a long flight and your wireless ones die on you). This adapter allows you to plug in your headphone and charge the iPad at the same time.

I have a van with no Bluetooth but has AUX input. Ugh! So I found this item and it works really well for me to get the Bluetooth off my Samsung Galaxy phone and also be able to charge my phone at the same time, which is crucial for us Nomads. Just be sure you have a good AUX cord for it!

Was exactly what we needed for to hook up and old car with a 3.5 mm plug for the aux. Now we can power the phone and listen to music.

Used this to connect my new iPhone 16 to the Audio jack in my car so I can play music through the “line in” feature. It also allows me to charge my phone at the same time. My car is pretty old so I don’t have Bluetooth. This works perfectly.

This plugs into a usb-c port and allows recharging and listening to music simultaneously with mini plug headphones or as an auxiliary input from iPad to amp via a mini plug.

Works fairly well
