Does the job!
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 ti...

Aux
Absolutely terrible, literally lasted a month and then started making a buzzing noise everytime the aux cord was plugged in. Very disappointing after I spent 40 dollars on this product.

Defective, does not charge, by design
Belkin is trying to trick you into buying a defective product. It DOES NOT CHARGE.
It does "slow charge" on my Pixel 7a when plugged directly into power. On my 2024 iPad pro, it says "not charging". When I called Belkin, they claimed neither the new iPad Pro nor the Pixel 7a are on their list of compatible devices for this product. Where is this list of "compatible dev...

Works fine, but note that the plug body is fat enough not to fit through the hole in some device cases.

Great adapter!
Compact, effective, and allows the kids to use their wired headphones. Exactly what we needed. Very pleased! Highly Recommended!

Disappointed
It does what it was designed to do. However, I have several problems with it. First, when I'm only using the headphone jack, my phone's battery is drained at an alarming rate. I have a brand new Iphone, which I assume many people looking at this product are buying it for. If I leave it playing audio through the 3.5mm jack without plugging it in, with the screen off, it ...

Charge time is doubled with adapter
Using this adapter with my "MY PHONE" doubles the charging time compared to just using the same power source and cord without the adapter. This was without even using the headphone port. For the price it should be able to do better than this. I'll really only use this now when I need to keep some power to my phone but also have to keep using my 3.5mm headphones (such as...

Will NOT transfer DATA - and that's a GOOD thing!
Works well, but the best thing about it is that the USB port will NOT xfer DATA, will NOT SYNC, and CANNOT be used for Backing Up the phone. It ONLY charges the battery. It is for POWER ONLY -- not DATA. When I plug it into my computer, the computer does not recognize the phone as a "connected device". (Also verified on the Belkin Website). And that is a GOOD THING - re...

Great 2 in one dongle
Great and affordable replacement so you can plug in a charging cable AND a pair of non Bluetooth headphones @ the same time.
Works great, no drivers needed on the IPad (pro or not,,,)
I suspect that both their usb-c and lightning models work equally well.

Not usable when charging port is plugged in
The adapter works ok with our Pixel 6 as long as the charging port is not used. Plugging in the charging port creates a lot of noise, so it is not usable to play and charge at the same time. After failing with this adapter I bought a Bluetooth to audio adapter and it works much better and was much less expensive.

Works great for what is does
This is great to have when you need to plug into your headphones phone jack and charger. Especially if you have a phone case that mashes using standard headphones plug. The bulkier cases make it impossible to use. Also good for AUX access if you can't use Bluetooth. I feel the use of this will become obsolete at some point with wireless capabilities being more and more ...

Fast Charge
I like that device is small and convenient to carry around in your pocket or purse. I use it on laptop that has a USB-C charging port. It charges my exterior speaker quickly. I wish the thick cable was a little bit longer, but it serves it's purpose.

Great for the office or traveling
I carry this little guy with me in my work bag and it's come in so handy over the past few work trips I've taken. It's small, and works well with my macbook air, and Google phone. It's perfect if you want to charge and listen to music or share music with another headphone.

Does the job and nice size to carry around
This is just what I been waiting for to release, I use my iPad pros for my graphic arts and rendering. Many times I always have a problem with other products taking a way the 3.5 audio jacks as a compromise. These new ones solves that problem and can trust this brand for being reputable.
