If you want a simple USB-C adapter with two ports for listening and charging, choose SZAWINLI Type C Distributor; if you need dual 3.5mm headphone jacks for sharing audio on flights, choose Vcddom USB C. For travel, the Vcddom’s clearly stated headphone-splitting design makes it the more useful pick for two listeners, while SZAWINLI is the simpler option when you only need to connect one USB-C audio setup and charge at the same time.
SZAWINLI Type C Distributor vs Vcddom USB C at a Glance
• Vcddom USB C: Combines two 3.5mm headphone jacks with a USB-C charging port, making shared listening straightforward. Its trade-off is that its headphone connections are 3.5mm, so USB-C headphones are not what those jacks are designed to connect.
• For one USB-C audio connection plus charging → SZAWINLI Type C Distributor.
• For two people using wired 3.5mm headphones while a device charges → Vcddom USB C.
• Who should pick SZAWINLI: Someone whose headphones and device fit its USB-C arrangement and who wants a basic two-port adapter.
• Who should pick Vcddom: Someone bringing standard 3.5mm wired headphones and wanting to share audio on a flight or road trip.
The SZAWINLI is described as a two-port USB-C adapter for audio and charging. Its listed charging capability is up to 60W PD. That combination points to a practical everyday role: keep a USB-C device charging while using a compatible USB-C audio connection, rather than giving up the port entirely.
The listed compatibility includes a range of older Galaxy S and Note phones, Google Pixel models from the Pixel 2 and 3 generations through Pixel 4 variants, and iPhone 15 and 16 models. It is gray and comes with a one-year warranty. Those details may help narrow the fit, but compatibility should be checked against your exact device and headphones before choosing it.
I’d consider SZAWINLI if I wanted two USB-C ports and already knew my audio gear worked with that connection. I’d skip it if I specifically needed two 3.5mm headphone jacks for sharing music or a movie. The available product information does not spell out support for that kind of setup, so it would be a mistake to assume the two ports mean the same thing as Vcddom’s dual headphone outputs.
Vcddom is the more explicit choice for wired 3.5mm headphones. It has two 3.5mm audio jacks and a USB-C port for charging, with a stated maximum charging capability of 60W. For a flight, that means two people can connect compatible wired headphones to the same adapter while the phone or tablet remains connected to charging.

Its compatibility list covers many models across iPhone, iPad, Galaxy, and Google Pixel families. It is white, and the listed warranty is 12 months. I’d choose it for two 3.5mm listeners or for a traveler who wants the audio connection spelled out. I’d look elsewhere if my headphones use USB-C and I need a matching USB-C audio port rather than 3.5mm jacks.
Side-by-Side: Which Should You Choose?
• Best for sharing wired audio with another person → Vcddom USB C. It has two 3.5mm headphone jacks, a clear advantage when two passengers want to listen together.
• Best for a USB-C audio connection plus charging → SZAWINLI Type C Distributor. Its design is described as a dual USB-C adapter for audio and charging.
• Best for standard 3.5mm headphones → Vcddom USB C. The two audio sockets are specifically 3.5mm, with CTIA and OMTP support listed.
• Best for a two-person movie on a flight → Vcddom USB C. Two 3.5mm connections are made for sharing, and the product details also describe travel use.
• Best if you need the simplest stated port arrangement → SZAWINLI Type C Distributor. Its two USB-C ports may suit someone with USB-C audio gear, but check the exact device and headphone compatibility.
• Best for listed audio specifications and controls → Vcddom USB C. Its product details specify a DAC format and inline controls for compatible headphones; comparable details are not provided for SZAWINLI.
• Best fit for a device not named in the compatibility details → Check carefully before buying either. The Vcddom sheet names a broader range of devices, but that is not a guarantee for every USB-C device or headset.
The big decision is not which adapter promises more charging power: both list up to 60W. It is whether you want USB-C ports or two 3.5mm headphone sockets. If your headphones already have a 3.5mm plug, Vcddom’s configuration is easier to understand. If you need USB-C audio, SZAWINLI’s port layout may be more relevant, but the available details leave more unanswered about the precise audio setup.
For shared listening, the difference matters even more. A single headphone connection means taking turns or using a separate splitter. Vcddom already provides two 3.5mm sockets, so it is the more direct option for a parent and child watching a downloaded movie, or two travelers listening to the same playlist. That does not make it automatically suitable for every headset: your headphones need a 3.5mm plug, and the device itself should be among those supported.
People searching for the best bluetooth earbuds for flights may not need either adapter if their earbuds connect wirelessly. But if the plan is wired listening, these products serve different setups. The phrase best head phones for flights often gets tangled up with adapter choice; here, the connector on the headphones is the first thing to check. For earphones for flights with a standard 3.5mm plug, Vcddom’s two jacks are the clearer match.
My Verdict
That is a more useful combination for me when two people may want to watch or listen together.
I’d choose SZAWINLI instead if I needed two USB-C ports and had confirmed my audio gear was compatible.
For the specific job of sharing wired audio, Vcddom is my pick.
It has two 3.5mm headphone jacks, so it is designed to connect two compatible 3.5mm headphones. Check that your device and headphones are compatible before relying on it for a particular setup.
The listed design is a two-port USB-C adapter for audio and charging. The available product details do not specify 3.5mm headphone jacks, so don’t assume it provides them.
Both are described as supporting audio while charging and list charging capability up to 60W PD. Actual compatibility depends on the device and setup; Vcddom also recommends using a PD wall charger for faster charging.
Vcddom is the clearer fit because it provides two 3.5mm audio jacks. SZAWINLI is described as using USB-C ports, so verify that its connection matches your headphones before choosing it.
