USB C to 3.5mm Audio Adapter 3Packs, USB Type C Headphone Adapter Hi-Fi DAC Chip, USB C to Headphone Jack Female Aux Adapter for iPhone 15, Samsung Galaxy S22 S21 S20 Plus/Ultra Note 20/10

The AuxLink Hi-Fi pro is a HUGE bang for the buck. This adapter is such a great deal! It is easy to use, tiny, and sturdy. It may be small, but it can handle digital-quality audio. The high quality DAC allows up to 384Khz/32bit just as advertised. There is no static sound when using this adaptor. The sound is crisp and loud. I am also very pleased with how secure and tight the fit is when connecting my 3.5mm earphones into this adaptor. I had purchased a cheap $5 adaptor and my major complaint with the cheaper adaptor is how loose the fit is when connecting my earphones into the adaptor. Sometimes causing the audio to stop in one side until I pushed the 3.5mm aux end into the adaptor again. A very annoying problem and which is why I decided to purchase this higher quality adaptor. I highly recommend this adaptor and for the price it is a good buy. Do not be fooled by the cheaper 3.5mm/type-c adaptors as you will not be satisfied as I wasn't.I also want to explain why you need an USB C adapter. Following Apple’s ‘brave’ move to ditch the headphone jack, many rivals have done the same. This means USB-C is a common connection for headphones, but how does it compare to the traditional 3.5mm jack? Ok, so Apple wasn’t the first tech brand to remove the physical headphone port from a phone, but those that went before - the likes of Oppo and Motorola – but they didn’t make the same impact.Let’s tackle the fairly obvious first. If your phone (or other device) doesn’t have a headphone jack then you’ll need to plug in via USB-C (assuming that’s the port of choice). We’re ignoring the existence of Bluetooth here, but you can, of course get wireless headphones.Plugging into USB-C means you’ll either need an adapter to use a traditional headphone jack, or get a pair of USB-C headphones like the Oneplus. Often, one or the other will be included in the box. The down sides here are that you might lose or break the dongle, or you want to charge your phone and plug headphones in at the same time.Having a 3.5mm headphone jack makes this simple as the DAC needs to be inside the phone so that when the signal reaches the 3.5mm port, your headphones can read it. Headphones can’t turn binary ones and zeros into audible sound without a DAC. However, USB C audio is better if we just look at the details of the digital audio on offer then you should get a better result. This is due to things like moving the DAC away from components inside your phone that can interfere for starters.The basic difference between 3.5mm port and USB C port is how both systems send out signals to external audio output devices such as earphones. The 3.5 mm outputs analog audio waves preprocessed by smartphone’s internal DAC and pre-amp. In this case, all a headphone/earphone needs to do is pass the wave directly to the diaphragm. The analog audio wave will drive the speaker.When it comes to USB Type C, they transmit digital audio data out from the port. Your normal earphones will not understand the audio data and cannot be used with this. In this scenario, the earphone which connects to the USB Type-C port should have A DAC (Digital to analog converter) and a pre-amplifier before passing the sound to the diaphragms.In fact, the Type C port is still able to output analog audio through its SBU pins. Here, the users can attach an adapter which will connect to the Type-C of smartphone and to the 3.5 mm headphone on the other end. The drawback is obvious, you need to carry an adapter with you whenever you need to listen to music which adds up to the inconvenience.Moreover, with a USB C port, things get a lot more tricky because the DAC can either be inside the phone or tucked away in the dongle. This lack of consistency means that you can’t just plug any dongle into any USB-C port and assume that it will work. If it doesn’t have a DAC inside and the phone doesn’t either, then you won’t get any sound. The simple solution is to stick with the supplied USB-C dongle or headphones. You might not want to do that though, since many other companies make better USB C dongle with more advance DAC. So make sure to check compatibility before purchasing.To sum up:Advantages of USB Type-C audio• Improvement in music qualityIf you are using a Type-C earphone with a good quality DAC, the sound quality will be improved. This is true when we talk about listening music in a budget smartphone.• Noise reductionProcessing the digital data inside a smartphone can be cause noise to be picked up and affect the music quality.• Top quality DAC’s can be used in earphonesA smartphone in the budget range usually houses an average quality DAC where pricey smartphones uses the high quality one’s. If your earphone has a high quality DAC installed, you should get a better sound.• More than just audioType-C audio can be enhanced to send more data than just audio.• Makes smartphone thinnerDisadvantages of Type-C audioThere are some practical compromises and drawbacks of having the Type-C USB port on you smartphone.• Audio quality largely depends on earphone manufacture• You won’t be able to charge your phone while listening to music• You will need to carry an extra device

I bought this in 2021 and still use it today in 2025. Easy to use and haven't had any problems with the connection.

Simply put, these enable you to connect your newer USB-C only phones/devices to all those things that you used to use (& more now) when you had a 3.5mm port on your phone/device.I have been reliably using these for streaming music, podcasts & youtube, etc. to a quality soundbar, a Pulse Bluetooth speaker (wired w/ Bluetooth off) &, a vintage 2+1 powered stereo PC speaker set all at the same time using 3.5mm splitters from this adapter. Yes, I know it seems silly w/ all those wires BUT, it does sound really great with this adapter's built in DAC chip using a variety of decent sounding equipment I already own from many years ago to recently.I do also use this adapter w/ an Anker 6 in 1 adapter to connect newer cellphones to my large TV via HDMI and to a seperate vintage HiFi stereo system (this adapter to double male ended cable & 3.5mm to 1/4" phono adapter plug), while charging phone & not casting to my smart TV (that's not connected to WiFi often) for web browsing, shopping, photos, music, video content &, movies, etc.These also work great for those gazillion wired earbuds laying around you can use/carry again as backup to your wireless earbuds or, your older "High End" wired stereo headsets. A caveat being that, depending on the power requirements of those really expensive headsets, there could be a lower max volume output, such as with a pair of older Oppo cans I tested. Haven't had an issue w/ smaller & recent headset models tested yet.NOTE: To help minimize wear of the USB-C ports, I utilize magnetic USB-C connectors which, do work with this adapter without compromising the sound quality (to my ear). Magnetic connectors make connecting from device to device quick & easy while protecting that only USB-C port you have from dirt, water (water resistant), & excessive wear occurring from repeated and or fumbling attempts to insert USB-C connectors on the go, in poor weather or light conditions, etc.I've tried other brands that failed, these havent failed in months & are a great value for the $$. Buy with confidence!

That's all I have to say for now. I think I'm going to order another as back-up. For fourteen bucks it's a bit ridiculous. I'm using on a Windows 10 laptop for Qobuz listening. It detected the device and automatically installed the driver in 20-30 seconds. As far sound quality, not the most sparkling detail and not the most amazing drive for larger headphones, but it powers a pair of Sony MDR-7506 absolutely just fine and will be *more* than adequate for IEMs with volume to spare (in both cases). Great value here. Reserving a star for future reliability.UPDATE: I'm not sure what the deal is with the many overheating reports but mine has never done so. I've used it, quite literally, each and every day for multiple hours at a time and it has never gone much above the ambient room temperature (confirmed yet again as I type this - it's cool to the touch at the 3.5 end and barely above room temp at USB end). I use it to directly power several IEMs as well a pair of Sony MDR-7506 and more recently a pair of Fidelio XR2HR. These are all very efficient headphones. Sounds like a possible build defect in some of them but luckily one mine seems to have avoided.
