Apple USB-C to 3.5 mm Headphone Jack Adapter

If you are thinking about saving a couple of dollars on buying an aftermarket 3.5 adapter for your iPhone, then do not. I have already tried. Although they work, mostly. Some have issues with microphone, on some volume control of your headphones does not work. Buy this original Apple adapter instead. Everything works as it should. The sound quality is the best. If you connect it to your windows laptop, it also works (including volume control buttons). There are three sound profiles supported by this device (CD, DVD and Studio) quality. On the aftermarket adapters I have tried, there is only one - DVD quality.

This might be a little expensive, like most Apple products, but it's the only adapter I've tried that doesn't suck for audiobooks. I wasted time (and $10) on inexpensive Chinese brands (KUXIYAN, OITYEUF) which all had static noise and a poorly designed auto-mute function. The auto-mute in the cheapo DAC is designed to make static less noticeable but it actually cuts off sound at the wrong time. The DAC mutes if the speaker takes a breath for 2 seconds, then it doesn't turn on in time so words seem randomly cut-off. In the last novel I was listening to, this kept happening on new chapters so I had no idea perspectives and locations were changing. That was a terrible experience.This doesn't apply to music which has constant noise in the background. So if you're just listening to music and dont care about minor static then you can just buy a cheapo one.The Apple adapter had NO problems at all. Just plug and play. No more micromanaging bluetooth earbuds(carry a bulky storage case, remember to charge, turn it off in settings if you want to switch device) and I can use my expensive IEMs. I wish I had simply started with this one instead of troubleshooting with different adapters, different phones, etc. It's shorter and thinner than my other adapters but that doesn't matter to me. This is the only time I've ever recommended Apple.

Truly it is weirdly good for how small and cheap it is. I’ve run $200 and $500 IEMs on it and had quality almost as good as, if not akin to, other portable DAC makers such as Fiio and Kiwi Ears. I cannot speak for its ability to power headphones as I do not own any high powered audiophile headphones, but for IEMs, this is perfect.

I bought this adapter to plug in my USB-C into a line for a cassette pickup for my 2000 Honda Accord. It fit my apple 16 pro and the cassette pickup. Just what I needed to get sound out of an old car stereo with a new apple phone.

Works as advertised

First I was looking for same if not better ear bud for conference calls than my old but worn Sony MDREX38iP, of which I had two sets. Then as the newer phones only have USB-C, I was also looking for USB-C dongle.I really like Logitech G333 (not the VR), however even at the lowest sound setting it's still too loud to be used in conference calls. So then I look for ear buds without USB-C and buy separate USB-C dongle (one of the reason why I liked Logi G333). After searching hi and lo, I searched no further, the Apple USB-C dongle is the best. It doesn't reduce sound output, i.e. it does not lower my voice in recording, it just make my voice sounds natural. And then considering the price of this, it's really a no brainer, I bough a handful of these so every time I misplaced them, I always have spares.

These dongles work great you so you can plug in wired headphones to your iphone or ipad, or so you can connect your iphone to a set of external speakers. The only issue that I have with this product is that I keep misplacing them. I think I've purchased a total of three or four by now because I keep losing the darn thing. No issues otherwise works as intended, and you can get losslesss audio out of these that you can't with bluetooth.

Believe the hype about the better sound with the Apple certified sound chip, the difference is noticeable and sounds great. Simple to use, but seems a little flimsy at times, though it keeps working fine.
