USB C to 3.5mm Headphone and Charger Adapter, 2-Pack Type C to Aux Jack Dongle Cable Cord with PD Fast Charging for iPhone 15/16 Pro/Max/Plus, iPad, Samsung Galaxy S22/S23/S24 Ultra, Note 20

Just got these and am extremely pleased with them. I was concerned whether they supported a full-fledged trss headset and they do. So YAAY !i am using these splitters on a chromebook and doing duolingo with it so i need both the ability to speak (microphone function) and to hear (headphone function.) And i wanted to be able to use the charger on the same (USB type C) port at the same time i am using the headset. And this Criello splitter does exactly what i need. (I tested both of the Criello splitters that i received and both worked fine.)Now as to longevity, i indeed plan to return if these splitters don’t last very long. But even then - if one were to fail - since there are two of them (and for very good price i should mention) at least if one fails i can still function by using the second one. (By the way - the chunky block part of the splitter does get a little warm but not probably above about 120°F. So not too worrisome at this point.)(NOTE: a trss headset has four connectors not three like a headphone connector. If the fourth connector is not present, the microphone does not work so that’s why i wanted a full-fledged trss connection.)“A trss headset utilizes a 3.5mm audio jack with four conductors (tip, ring, ring, sleeve), allowing for both stereo audio output and microphone input.”

Apple's no headphone jack approach - designed to force you to buy expensive airpods - is not for me. I wear my headphones at work and the batteries run down after a few hours. I regularly had to switch to my backup wireless headphones while the airpods were charging - not anymore!Now, I can use my superior sounding wired headphone while charging the phone - a win-win situation. My phone stays charged and my wired headphone never need charging.To make the deal even better, there are two adapters and they're inexpensive. These adapters are plug-and-play so insert it into the USB-C port, hook up your charger and headphones and everything works.

These worked out of the box. I ordered different formats (small one part dongle, a cord based one, and this one). Functionally, this one seems to work well, especially if I want to charge while listening. I would take a pic of it plugged in, however I only have my phone and it can't take a pic of itself with this plugged in. I went through all the ones I ordered listening to a song each before unplugging and plugging in the next. I was using my gaming headset with the cord attachment (4 conductors, BTW with the extra mic connection). This ignored the mic connection like it should.The charging ability worked, although I don't know if it's slow or fast, I was already in the 90% range but my iPhone 16 Pro Max indicated it was charging when it was plugged in. The audio is mediocre however. I come from a former professional audio background (former broadcaster/audio production career) and I can recognize a good audio range when I hear it. This connector seems to produce mostly mid-range but no rich highs or lows. This could be related to the chipset because the USB-C connection is actually data into the phone itself. For the price and what I was able to test after receiving it today, I rate it 4 stars.

I love these adapters and you really can't have too many. It was frustrating when headphone jacks started to disappear from phones, but this product makes it all OK. I love that it has a charging port so that you can listen on headphones even while the phone is plugged in to charge. The 2 pack is great so you can keep one in the car or your purse and the other at home.

I got two adapters and both of them stopped working within a week. Very poor quality.I have to add that the seller contacted me of their own accord and refunded me for the cables so that showed integrity on their part. Thank you to the seller for addressing this.

I tried many adapters to connect my MacBook Air to my external (non-Apple) monitors, this one worked with ZERO issues! 100% satisfied!

Bought to connect my phone to the aux on my radio in the truck. My phone doesn't have the 3.5 mm jack so I needed to use the USB C plug. This allows me to charge my phone and play music at the same time. Very easy to use and functions great.

Audio: The audio is okay. No highs, no lows. It could also be a function of the cheap earbuds I am using also.Power: Charging rate is slower but it keeps up with phone usage.The problem I am having with this adapter on a Oneplus 7T Pro is that I can't charge and use headphones at the same time. When I plug in a charger, the headphone icon disappears and the headphones disconnect. The headphone icon and audio returns only when the charging cable is removed.If I can't find a resolution, I will likely return them.Seller reached out to me to but we were not able to resolve the issue. Seller was super helpful and did everything they could to resolve before the return. Ultimately we're were not able to get it to work on my phone and seller was understanding. They were extremely quick in answering questions and concerns returning my messages the same day.An additional note, I actually bought 2 sets of these adapters. My daughter's iPhone 15 works perfectly with it charging and using the headphones at the same time. Due to this and great customer service, I am changing my review to 4 stars as I think it is just a phone compatibility issue and not a faulty adapter.
