If you want to keep using your favorite wired 3.5mm headphones while fast-charging your phone, choose Eusbote Type C; if you need to split one USB-C port into two USB-C connections so you can charge and listen through a USB-C headset, choose KINDRM USB C Splitter.
• Eusbote Type C — biggest strength: it splits your USB-C port into one 3.5mm audio jack plus one 60W PD charging port, so classic wired headphones and charging happen at the same time.
• Eusbote Type C — biggest trade-off: it is built around the 3.5mm analog jack, so if your headphones end in a USB-C plug, this is not the adapter for you. It also does not pass data.
• KINDRM USB C Splitter — biggest strength: it gives you a 1-in-2-out USB-C split, letting you charge at 60W PD while feeding audio to a USB-C headset, and it lists PD, QC, AFC and PPS protocol support.
• KINDRM USB C Splitter — biggest trade-off: there is no 3.5mm jack at all, so traditional wired headphones need their own adapter. It is also not compatible with Amazon Fire Max.
• Who each pick is for: Eusbote for the 3.5mm holdout who wants one small dongle; KINDRM for the USB-C-headset user who wants a two-port splitter with a stated one-year manufacturer warranty.
The Eusbote Type C is a 2-in-1 dongle with a very specific job: it takes one USB-C port on your phone and turns it into two useful things — a 3.5mm female audio jack and a USB-C port that supports up to 60W PD 3.0 charging. That combination is the whole point. You plug your wired headphones into the 3.5mm end, plug your charger into the other end, and you can listen to music, take calls, or watch video while the battery keeps climbing. It is plug-and-play, with no drivers or apps to install, and the 3.5mm port works with both CTIA and OMTP standard headsets.
Audio is handled by a built-in DAC chip rated at 24-bit/96kHz stereo, and Eusbote describes the signal path as stable and lossless with no current noise, plus HD voice call support. Volume control works through the adapter. The physical build is a purple aluminum alloy shell with a nylon-braided cable, and the whole thing runs about 18cm — short enough to leave attached in a pocket or bag without tangling into a knot. It weighs roughly 3.5 grams, so you will genuinely forget it is there.
Who should skip it? If your headphones end in a USB-C plug rather than a 3.5mm plug, this adapter will not help you — you would need a USB-C-to-USB-C split instead. Skip it too if you need data transfer, because the Eusbote does not support it. And one honest caveat straight from the spec sheet: it may not support QC charging on some newer phones, so a PD wall charger is the recommended pairing to get the faster charging speed.
KINDRM USB C Splitter: Who It's For
The KINDRM USB C Splitter is also a 2-in-1, but it is aimed at a different listener. Instead of a 3.5mm jack, it splits one USB-C port into two USB-C connections — one for a USB-C headphone or headset and one for a charging cable. That means you can listen through a USB-C headset while pulling up to 60W of Power Delivery into your phone, tablet, or laptop. KINDRM states support for PD, QC, AFC and PPS protocols, with an intelligent chip that identifies the device and adjusts voltage and current to keep charging safe and efficient.
On the audio side, KINDRM leans hard into the "studio-grade" pitch: precision signal pathways, advanced noise suppression, and a claim of distortion-free, static-free sound for calls, music and streaming. It is plug-and-play, with no drivers or apps, and KINDRM walks you through the order of operations — connect the headphone plug and the charging cable to the splitter first, then plug the splitter into your device.
The compatibility list is broad and skews toward larger devices as well as phones: iPhone 15/16/17 series, Galaxy S25 Ultra/S25+/S25, Pixel 9 Pro/9, MacBook Pro and Air 2024, iPad Pro and Air 2020–2025, XPS 17/15/13, Dell, HP Chromebook x360, Surface Book 3, Samsung Tablet S9, Note 20, LG V40, Valve Steam Deck and Switch 2. The color is black, and it carries a one-year manufacturer warranty with a stated 24-hour response window for customer service questions.
Who should buy it? If you have already moved to a USB-C headset and you want a single small splitter that keeps both charging and audio flowing — especially on a laptop, tablet or handheld like a Steam Deck — this is the more natural fit. The protocol coverage (PD, QC, AFC, PPS) is also broader than what Eusbote advertises, which matters if you want flexibility across chargers.
Who should skip it? Anyone committed to 3.5mm wired headphones, because there is simply no analog jack here. Skip it if you own an Amazon Fire Max, which KINDRM explicitly lists as incompatible. And as with Eusbote, data transfer is not supported.
• You own 3.5mm wired headphones → Eusbote Type C. It has the actual analog jack; KINDRM does not.
• You own a USB-C headset → KINDRM USB C Splitter. Two USB-C ports, one for audio and one for power.
• You want the widest charger-protocol support → KINDRM USB C Splitter. It lists PD, QC, AFC and PPS; Eusbote lists PD 3.0 and warns that QC may not work on some newer phones.
• You want the smallest, lightest thing to leave in your pocket → Eusbote Type C. It weighs about 3.5 grams with an 18cm braided cable.
• You want to charge a laptop, tablet or handheld while listening → KINDRM USB C Splitter. Its compatibility list explicitly includes MacBook, iPad, XPS, Surface Book 3 and Steam Deck.
• You want a stated warranty → KINDRM USB C Splitter. It carries a one-year manufacturer warranty.
• You care about audio spec transparency → Eusbote Type C. It names a 24-bit/96kHz DAC and CTIA/OMTP support, which is the more concrete audio spec of the two.
• Best for a phone-only setup with legacy headphones → Eusbote Type C. Best for a mixed-device, USB-C-native setup → KINDRM USB C Splitter.
In my opinion, the deciding question is not which adapter is "better" — it is what is already in your bag. If you have a drawer full of 3.5mm headphones and you want one tiny dongle that keeps them alive while your phone charges, I would buy the Eusbote Type C. The 24-bit/96kHz DAC, the CTIA/OMTP support and the 60W PD passthrough cover that job cleanly. If your headphones are USB-C, or you want to charge a laptop or handheld while listening, I would buy the KINDRM USB C Splitter for its dual USB-C ports, wider protocol list and one-year warranty. Pick based on the plug on your headphones, and you will not regret either one.
FAQ
Yes — that is exactly what its 1-in-2-out design does. You connect your USB-C headphone and your charging cable to the splitter, then plug the splitter into your device, and both audio and up to 60W PD charging run together.
No. Both product data sheets state that data transfer is not supported. They are audio-and-charging accessories only.
Value here comes down to your connector type, not the number on the page. Match the adapter to your headphones and your device, then check the current price on Amazon before you commit.
