JSAUX USB Type C to 3 5mm Female Headphone Jack Adapter USB C to Aux Audio Dongle Cable

This USB-C to 3.5 mm adapter is a solid buy. The charging speed remains consistent when used with supported devices, and I haven’t noticed any drop in performance while listening. It’s very portable, small enough to keep in a pocket or bag without getting in the way. The durability is impressive for such a compact adapter—the connection feels sturdy and not flimsy like some cheaper options. I also like that it handles both audio and charging smoothly from a single power source, which makes it extremely convenient for everyday use. Overall, this adapter is reliable, well-made, and perfect for travel or daily carry. Highly recommend. Read more

Analog headset adapters used to be 1/4" in diameter. We put those on our heads to listen to the "record player". Then they were replaced by 3.5mm jacks that also included a microphone signal. Those were used by the original cellphones, everything from AMPS to CDMA, TDMA, GSM. With smaller technology and slimmer LTE and 5G phones we now use the USB-C connector. If you still have a 3.5mm audio headset, wired earbuds, etc. and upgraded to a phone without that jack you can use this adapter and not have to buy a new headset. In my case I have a Bose Quiet Comfort 20, with automatic noise cancellation, amazing sound quality, and $195 to replace. Instead of replacing the Bose QC20 I picked up this adapter, plugged the QC20 into the 3.5mm female jack, plugged the USB-C male on the other side of the short cable into the phone. I can now use the headset just fine. It truly is plug and play. It comes with printed directions in a clear vinyl bag, but you really just plug it in between the headset and the phone. No configuration required, no settings changes. It works with iPhones, Android, Linux, etc. Pretty much if your USB-C device supports audio out and in (TRRS) this will work. Troubleshooting? It's impossible to have trouble, so no need to go shoot any. Plug in both sides. Done and done. Read more

Works perfectly as expected. No static noise, and it’s just plug and play. The cable is braided so it is very strong, and it’s the perfect length. Read more

UPDATE: I have changed my review from two stars to four stars. I will note that JSAUX offered me a full refund for my order but I did not accept the refund. I ordered an official SAMSUNG adapter DAC that had verifiable measurements online for quality and found that this hiss was also present to a similar degree. While this continues to annoy me, the hiss is inherent to using a small form factor dongle DAC and does not reflect the quality of this JSAUX product which is functional in all other aspects. I recently upgraded phones and lost my 3.5 mm port so I was looking for a durable adapter with decent audio quality. This adapter certainly works as my IEMs run well off them with enough power/volume without any significant coloration of the sound. The build quality is quite good with the braided cable, solid housing, and secure 3.5 mm port. But the HISS. There is a low grade hiss constantly present in the background whenever the DAC is enabled. It is not particularly noticeable when music is actively playing but when a song stops, you can clearly hear the hiss. Then since the DAC doesn't detect any audio output, it shuts off, and you then hear complete silence so I know it's the DAC causing the issue. This means every time a song ends and new one begins, it's hiss -> silence -> hiss -> music. There are no other devices around that could be causing electrical interference causing a hiss like this. It is not ignorable for me and really impairs my listening experience. I suppose if you have low grade hearing damage, it might be tolerable but for high quality listening? This is not it. I will be shelling out more money for a better engineered DAC dongle and would recommend any potential buyers do the same. Read more

This is the only headphone adaptor I will use. It is extremely durable and lasts a long time. I always keep several on hand because they are small and easy to misplace, but they are high quality. They do work for phone calls as well as long as you buy headphones with a microphone. If the headphones don’t have a microphone you will be able to hear the other person, but they won’t be able to hear you. The size is perfect and I typically just leave it connected to my headphones for easy use. I use headphones constantly so this is a must have for me. Overall, I will continue buying these because they are exactly what I need and I know they work well and last a while. They are also a great price for something that works. I have bought some in the past from a different brand that was half this price but they broke after 1-3 uses, where I use each of these for months to years before typically misplacing it. I’ve never actually had one stop working. I will say that as they get older that they get picky and prefer to be inserted in one way, so sometimes if it isn’t working, pulling it out, flipping it over, and inserting it the other way can be beneficial.

I initially thought the adapter didn't work! I bought it to connect my Galaxy S24 with my Bose Wave III (which is not bluetooth enabled). I connected the AUX in cable that came with the Bose to the adapter cable and to my phone. I selected AUX IN on the Bose, then opened Prime Music and pushed play - No sound!! Thanks to a little sleuthing I found that you need to turn up the volume on your phone to over 90% before you'll hear any sound coming from the Bose. Then adjust the volume directly on the Bose. Worked like a charm. I love a simple solution. Wish I had bought the adapter a long time ago. Read more
