Customer Ratings & Reviews

Great product for traveling. I usually use wireless headphones but don't want to use them on a plane to not drain my battery and this product allows me to use regular headphones and still charge my phone, like the good ole days when we had headphone jacks in phones. Fast charge seems to still work and the sound isn't hindered in any way.

I just got a iphone 15 pro and i needed something i could use to play music in my car while my phone charges. It works. Music, charging. No problems.

This is a simple product it does the job it’s suppose to and haven’t had any issues after all this time1

It does what is says it does. Nothing crazy to write home about.

I got this because i have a vehicle with no Bluetooth and my phone has no headphone jack. So this works great. Just plug into your c charging port.

The product itself works as intended. I purchased one last week as an experiment to see if it could be connected to the front USB-C port of a PS5 to transmit both sound AND charge the remote simultaneously. The short answer? No. However, when it comes to the intended use of the products it does its job and it does it well! I was able to test this out on my iPad Pro and the product enabled me to both charge my iPad and listen to it using my plug in headphones. I don't feel that the charge slowed down in any way which is a plus!

Worked well for about two weeks and then the wires inside were sever from constant movement so it was probably meant more for use in a car audio quality was alright but notably worse than the adapter that I didn't know was in my phones box The ability to charge my phone while listening to music with this was nice though

This unit works well, allowing use of a headphone stereo plug while charging an iPad. There is one small issue I noticed worth a comment. If used with the original Apple power supply, the unit works properly and allows for charging of the iPad through the unit. However, if used with a generic power supply, especially one with a lower power, the unit does not charge the iPad. This may be why some reviewers say the unit doesn’t work. It appears to need either a higher power supply current (like from an 18 watt Apple charger) or perhaps there is some special protocol required of the power supply. So, just to summarize, it works as advertised with the original Apple charger, but not with other, lower power chargers.

This is a very niche product. I use it because my vehicle (2013 gmc terrain sle) does not use bluetooth to play music. Newer phones ditch the digital to analog converter as is the case with my new galaxy s23 ultra, so an aux cord with a normal usb c adapter will not work in my car. Luckily this product has a built in dac chip. Plugging both the aux cord and usb cable from my car into this product and then into my phone allows me to play music off my phone through my car and charges it simultaneously. Im sure some people here are trying it with just one of the cables which will never work. This product works fine but loses a star because it is pretty wildly overpriced.

worked perfectly for what we needed it for, saved the wedding!!

Works fine, but not worth the price. I'm using this in my car to charge and play audio with a Samsung S21+. Someone using it for more would likely have a better cost analysis. There's a USB C and an aux, not much else to use this piece for. It feels like good quality.

Works great and exactly what I needed. Small and compact.

I got this to replace a simple usb-c to headphone adapter I have been using since I damaged my 3.5 mm headphone jack on my phone. I don't use it a lot but it comes in very handy when I need it. I have two vehicles without bluetooth and I prefer just to use a wired connection. This lets me charge my phone and use headphones or the auxiliary input in my car at the same time. The sound is clean when it is charging and without any interference. I also like that it is small and simple and does exactly what I need it to.

After upgrading from an iPhone X to a 16, my 2012 BMW stopped charging my phone through the USB port in the center console. I needed a way to send audio to the Aux port in the center console, but USB power to a separate charger that hooked up to the 12V DC outlet under the glovebox. This worked perfectly.

It works well when using it. I have it in my car to play my music or audio books through my aux in. It plays well when the sound is on, but I’ve noticed that if I don’t leave it hooked up to my phone it has a horrible buz that plays through the speaker. Probably a grounding issue? It may be just my car, but the last model I had didn’t do that.

Works fine; (depending on which phone case brand is used), DOES NOT always fit phone's USB-C female phone port, making it completely useless. Before purchasing it, CHECK if it'll work with your particular phone case style/brand. (The problem is that its USB-C male plug design has its plastic casing a few mm wider than some phone case cutouts are; my compostable phone case, for example--though it works with all other USBC-type male plugs--will not fit right, as a consequence the phone won't play or charge).

It apparently has some built-in software or firmware. I saw that load up on my iPad screen when I first connected the Belkin device to it. I saved the printed matter that came in the box with the Belkin device. I have not yet read that. I did have a problem when the sound momentarily stopped coming out of my large Brookstone speaker to which I have my new iPad connected. At the present time, the Belkin device works when connected to the new iPad and the Brookstone speaker. After I disconnected the Belkin device and connected my cell phone to the Brookstone speaker, no sound came out of either the large speaker or the cell phone's speaker. It had previously worked. My TCL cell phone does have a 3.5 mm headphone jack. It has previously worked just fine with the big speaker. I hope that the next time I try to connect my cell phone to the big speaker, it works. I was not using the Belkin device the last time I connected my cell phone to my big speaker. It was not necessary to do that. I won't be returning my new Belkin device because I know that I definitely cannot hear any sound coming from my Brookstone speaker through my new iPad without it.

Awesome buy! BELKIN 3.5mm Audio& USB-Usb-C Adaptor allows my Galaxy two fold phone for my ear buds connection and has charging capability while diriving long distance, home and car stereo usage.

It’s what I needed and does precisely what I need it to do. Since my car doen’t have wireless pairing, needed this adaptor to stream audio through my car speakers from my iPhone. Allows me to also charge my phone at the same time.

My new Motorola Razr+ 2024 (like most ne phones does not have a 3.5 mm audio jack. I have Audio technica Quiet Point wired headphones so I am not about to fork ou another $250 plus to replace them. This adaptor solves the problem. The built in DAC maintains the pristine audio quality and so far I have had no problems.
