If you want a more compact, lightweight-feeling adapter with clearly stated audio and cable details, choose Eusbote Type C; if you need a broader compatibility list and call controls, choose SIXSIM USB C. For Switch use, I would lean toward SIXSIM USB C when its listed features suit your setup, but neither product sheet confirms Nintendo Switch compatibility, so check your console and headset requirements before choosing.
• Eusbote Type C strength: Its listing specifies a short, 18 cm nylon-braided cable, an aluminum-alloy connector shell, and 24-bit/96 kHz audio support. Trade-off: Its compatibility and controls are described mainly around phones; Switch support is not stated.
• SIXSIM USB C strength: It lists a broad range of compatible phones and says its built-in chipset supports volume control and answering calls on compatible devices. Trade-off: It does not provide cable length or construction details in the available product information.
• Both split one USB-C connection into a 3.5 mm audio jack and a USB-C charging port, with charging support up to 60 W PD.
• Neither adapter supports data transfer, and neither product sheet confirms compatibility with the Nintendo Switch.
• Choose Eusbote if you value its stated cable construction and audio specifications; choose SIXSIM if its wider listed device coverage and call-control feature matter more.
Eusbote Type C is a small USB-C adapter for using wired 3.5 mm headphones while keeping a USB-C charging connection available. That arrangement can be useful when a phone has a single USB-C port and you want to listen through a wired headset without giving up the ability to charge. The adapter also supports volume control, and its listing says it works with CTIA and OMTP headphone standards.
The audio specifications include a built-in DAC and 24-bit/96 kHz stereo support. Eusbote also describes the adapter as supporting high-definition voice calls. For charging, its USB-C port supports up to 60 W PD; the listing recommends a PD wall charger for faster charging and cautions that QC charging may not work with some newer phones. Those details make it a practical phone accessory on paper, but they do not establish how it will behave with a Switch.

SIXSIM USB C has the same basic two-connection purpose: plug a 3.5 mm headset into one side and a USB-C charger into the other. It supports up to 60 W PD charging, and its listing says the built-in chipset can support volume control and answering calls on compatible devices. That could make it a useful phone adapter for someone who wants wired audio and charging through one USB-C port.
Its compatibility list names a wide selection of Apple, Samsung, Google Pixel, and Motorola phones. That is useful if you are shopping for a phone accessory and want to compare your model against the product's listed devices. The list is not a substitute for confirming the exact model, though, and it does not mention Nintendo Switch compatibility. The product information also says that the adapter does not support data transfer.
For audio, SIXSIM lists DAC support at 16-bit/192 kHz or 24-bit/96 kHz, along with ADC support at 16-bit/48 kHz. It also says the adapter supports CTIA and OMTP headphone standards. Unlike Eusbote, the available information does not specify a cable length or describe the cable and connector materials. I would consider SIXSIM if its listed device coverage and call controls fit your needs; I would look elsewhere if you need published cable-construction details or verified compatibility with a particular console.
• Best fit for a phone on the listed compatibility range: SIXSIM USB C has an extensive list covering many Apple, Samsung, Pixel, and Motorola models. Check that your exact device appears before buying.
• Best for a stated compact cable setup: Eusbote Type C specifies an 18 cm cable. That gives you a clearer idea of the adapter's cable reach than SIXSIM's available product information does.
• Best for stated cable and connector materials: Eusbote identifies a nylon-braided cable and aluminum-alloy connector shell. SIXSIM's product information does not describe those materials.
• Best if answering calls through the adapter matters: SIXSIM specifically lists support for answering calls and volume control on compatible devices. Eusbote lists volume control and HD voice calling, but does not state the answer-call feature in the same way.
• Best for keeping wired audio and charging connected together: Both products provide a 3.5 mm audio jack and a USB-C charging port, with up to 60 W PD charging. Neither supports data transfer.
• Best bluetooth earbuds for Switch: Neither adapter is a Bluetooth earbud product; both are designed for wired 3.5 mm headphones. If you want Bluetooth earbuds, these are not the right kind of accessory.
• Best headset for Switch: Either could be relevant only if the Switch supports the particular USB-C audio and charging arrangement you intend to use. The product information does not confirm console compatibility, so verify that first.
• Best long battery life bluetooth headset for Switch: Neither product has a battery. They are audio-and-charging adapters, so battery life depends on the headset or earbuds you pair with your console, not on either dongle.
My Verdict
Neither product's listed information confirms compatibility with Nintendo Switch. Both are USB-C adapters for wired 3.5 mm audio and charging, but you should verify the console's requirements and the specific setup you plan to use.
Both adapters split a USB-C connection into a 3.5 mm headphone jack and a USB-C charging port. Each lists charging support up to 60 W PD. Neither supports data transfer, and the stated charging figure alone does not confirm how fast a particular device will charge.
Eusbote specifies 24-bit/96 kHz stereo audio. SIXSIM lists DAC support at either 16-bit/192 kHz or 24-bit/96 kHz and ADC support at 16-bit/48 kHz. These listed figures describe supported audio formats; they do not establish which adapter will sound better with every headset or device.
Both listings mention volume control. SIXSIM also says its chipset supports answering calls on compatible devices, while Eusbote describes support for HD voice calls. Actual controls may depend on the connected headset and device, so check compatibility if those functions are essential.
