Subynanal 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 for iPhone 17 Iphone16, iPhone 15, Galaxy (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.

This has worked well for several devices (Apple and Google phones, Samsung tablet), and with different headsets (both TRRS plug for stereo headphones with microphone, and TRS plug for stereo headphones without a mic). Another dongle made by another company was flaky when used with audio-only TRS plugs, so I'm sticking with this one because it just works. Audio and charging are both fine independently or together.

I use this to listen to podcasts while I go to sleep. Several nights ago, my Pixel 7 started turning off in the middle of the night and got into a constant loop on the boot screen. It wouldn't charge while doing this. After spending a few (6?) nights experimenting, I determined conclusively that it was this dongle causing the issue. The phone would not boot normally until this dongle was removed from the USB port, regardless of having power or headphones plugged in. I tried to begin my Amazon return to it exchange it, and realized I missed the return window by hours... Bad timing on my part! Edit: The issue went away by itself over the last few days! The seller also contacted me and offered a refund, which I no longer felt I needed since it was working as intended. I only wish I could identify what the root cause was.... Raised rating to 5 stars based on my experience. Good job, seller!

If you expected it to charge and listen to music at the same time, it doesn't. Much to the dismay of my boyfriend, who likes to be able to listen to music from his phone on roadtrips, but can't if his phone runs low on battery. For separate functions, it works great! Just not a dual function item.

Unfortunately, I can not recommend this item because, when I plugged it into the USB-C (located on my Samsung Galaxy Smartphone) absolutely NOTHING happened?! My phone did not display that there was any thing to connect to? This item does not work at all. Buyer beware! Thankfully, I purchased 3 different brands when I placed my order--and I highly recommend the brand UGREEN! Plugged it into my phone and it immediately started working (no additional instructions needed!) Honesty is best policy --so I'll pass it forward via posting a verified purchase review and hopefully this will save you a lot of wasted time, disappointment, money, and any extra hassles.

Excellent solution to switching cables

Mine is still working great at over 5 months of use. I use at night when I listen to old radio shows, with my old earbuds) to fall asleep to and I can wake up with a fully charged battery. It gets slightly warm were the charger plugs in when the battery is very low, but it never gets alarmingly hot. I'm using it with Motorola Edge 2024. Yes, plugging in the charger pauses audio, but after pressing play again you can charge and listen at the same time.

Perfect if you need this configuration, I however had rather stupidly bought this twice and realized that it wasn't actually the configuration I needed. The person I gave it to loved it and said it worked great.

Used it on my Motorola Razr+ 2024. Works wonderfully with my DJ headphone to listen to music, and my headphone with mic to talk on the phone. But the second you plug power to charge, it cuts the headphones off. Only one can work at a time, which defeats the purpose of the product. If you wish to use both ports at the same time, it may not work. Not a recommended buy ... Sorry

Used on iPhone 15 pro max. Crackles and distortion when used in car with charging - original “lower quality” equivalent does not have these problems. The problems didn’t show when used indoors with headphones and charger connected. However, it was purchased for car use, so returned.

Era exatamente o adaptador que eu queria e carrego meu celular enquanto uso o fone de ouvidos ao mesmo tempo. O vendedor , T. Paine, foi muito correto e recebi antes do prazo o produto . Muito satisfeita com a experiência de compra

Sometimes activates Google assistant while driving, gets in the way. Audio quality and volume on the jack are way better compared to the Apple adapter I used to use. Charging seems to be the around same as without the adapter

Al fin encontre un conector para usar el puerto C para conectarlo auna mezcladora y extraer tdo el mejor sonido de mi Tableta Samsun Galaxy A8, aunque este modelo no venia incluido en la descripcion del vendedor, me arriesgue y si es compatible com mi Samsung
