UGREENMagnetic USB C to 3.5mm Audio Adapter and Charger 2 in 1 Hi-Res 32bit/384kHz Aux to USB C with PD 60W Fast Charging Dongle Cable for iPhone 16 Pro Max, Switch 2, Galaxy S25Ultra, iPad Pro

Overall, this is a fantastic product for those wishing to have an aux port while being able to charge their phone. It works amazing still after having bought this product back in August of 2024. This has survived being unplugged and plugged back in a multitude of times. This will occasionally have a small humming sound due to the charging if not consistent such as in a vehicle having the engine rev up and down you will occasionally hear that. Overall however, this is a fantastic product for the price and delivers audio that I was hoping for while still being able to quickly charge my phone if needed. The other nicety is not having to worry about the what ifs of a wireless headphones. The what if I forgot to charge it or having to pay for that more expensive headphones. Furthermore, it is nice to have just to connect to a car if it does have an aux port. Another use case is using it to connect to a stereo system to play music if you do not have one that has Bluetooth functionality.

So far I've had no problem using this. I'm able to charge my phone while using it as a poor-man's DAC to play music through my old stereo system. The connection is stable and I haven't heard any popping, hiss, etc. I know this isn't an audiophile device, but neither is a smartphone. This sure beats the hell out of Bluetooth though, and you can still charge your phone. I've been thinking of using an old phone as a dedicated media storage device until I get an actual dedicated one.The design is very durable and the components are housed in metal housings. Magnets are built into them which holds the two ends together, which is more handy than I originally thought. Old stereo systems can become a mess of wires pretty quickly and when you include a 2.5mm to 1/4" adapter to connect the old stereo-in plug to the amp it's a lot. This little device is perfect for my needs. I haven't noticed any heating issues but I have a dedicated amp. I'm using this as an adapter and I don't know how it would perform if you tried to power speakers directly.I think the value is great and the shipping was fast enough that I didn't move on to another project for a few weeks. It's a great buy and already paid for itself. I'm using VLC on my phone (free) to play my mp3 files, but you can use whatever you like if you don't care about owning music.

Getting this adapter is an unnecessary necessity if you know what I mean. My old smartphone still had a headphone jack and a USB-C charging port, but hardly any new smartphones in 2025 have the headphone jack anymore -- I knew I was going to have to purchase this when I eventually caved and got a new smartphone. I do like that you can connect the two ports magnetically together, just to keep them more organized. The audio quality from the 3.5mm seems solid, but I'm no audiophile of course. The USB-C port for charging supports the fast charging of my smartphone which is what I was hoping for. Can't speak to the longevity of the device as I've only had it for a few weeks, but it seems to be a solid adapter that does exactly what is advertised.

Whether it is in the car, office, or at home, if you use a 3.5mm dongle for audio these days, the struggle of running on battery because the ONE usb C port on your device is occupied by a dongle is infuriating. Magnetic charging is kind of a solution, but I like to avoid it when I can due to battery heating issues on some phones with cases. This device makes all of that go away. The DAC on this is not going to set the world on fire. It will drive most IEMs or car stereo systems. Don't expect audiophile grade audio here, but the value for money and the lifesaving feature of being able to wired charge and listen to music is amazing. There is no noticeable noise I can hear from the power cord even on sensitive IEMs, and that's what sets this device apart from other cheaper options. Good build quality that doesn't get hot while charging. 100 percent recommend if you're in the market for this type of dongle.

Originally I had purchased the incorrect item for my needs. I realized before delivery, and began return policy. I was refunded promptly and able to reorder the correct item. My correct, this specific style linked with the review, worked very well. Until it didn't. I began noticing issues approximately a week or so after my Amazon Return Window had already closed. I don't know why but it seems to not want to connect to my cell ( Samsung A36 ). On a whim I reached out to UGREEN directly, and they were very polite, prompt with replies, and offered me a viable resolution to my problems. Bottom line, I guess I just got unlucky with my item, but wanted to reassure to all that UGREEN is an excellent, very honorable company to purchase from. I likely will again with no hesitation.

Great Little Device For Those Who Own Late-Model Cellphones That Have Sadly Done Away With The 3.5mm Headphone Jack. I Purchased a Samsung Galaxy Note 10+ About 2yrs Ago and Thoroughly Missed Having a Headphone Jack For Listening To My Hi-Fi Music on My TIDAL Account. I Had To Resort To Carrying Around A Whole 2nd Device (LG V60 Quad-D.A.C.) Just To Listen To My Music. I Purchased Numerous Dongle D.A.C.s But The Downside Of That Was It Would Drain Your Device's Battery While You Were Using The Dongle D.A.C. At Least With This Adapter You Can Still Charge The Device If Needed and Still Listen To Media/Music.

Better than most. Great dual jack for charging and listening to hardwired headphones. I purchased for the dual. I still prefer hardwired headphones when I’m just focusing on the music and want to hear every detail. Hardwired still produces better sound quality for those that value that level of audio detail. Noise levels are great, no discernible problems or glitches that you can get with cheaper versions. Charging speed is very good as well.
