If you want a compact USB-C splitter that keeps a USB-C headset connected while your phone fast-charges, choose Togconn Dual USB C; if you need a dongle that turns your USB-C port into two 3.5mm headphone jacks while it charges, choose Kemsky USB C Double.
These two adapters look like twins in a search bar, but they solve different problems. One passes USB-C audio through and charges at the same time. The other converts USB-C to analog 3.5mm audio for two listeners and charges at the same time. Pick the wrong one and your headphones simply won't plug in — so let's sort that out before you buy.
• Togconn Dual USB C — biggest strength: a true USB-C-to-USB-C splitter. One male USB-C plugs into your phone or tablet, and you get USB-C audio out plus PD 60W (20V 3A) charging in one tiny space-gray aluminum dongle.
• Togconn Dual USB C — biggest trade-off: it only speaks USB-C audio. If your headphones end in a 3.5mm plug, this is the wrong adapter, full stop. It's also a single-listener device — no second jack.
• Kemsky USB C Double — biggest strength: 3-in-1 design with two 3.5mm jacks and PD 60W charging, plus a built-in DAC rated up to 24bit/96kHz for Hi-Res decoding.
• Kemsky USB C Double — biggest trade-off: it's the opposite limitation. Modern phones without a headphone jack love it, but a USB-C headset won't connect — there's no USB-C audio port on it, and the body is ABS rather than metal.
• Who each is for: Togconn for USB-C headset owners who want charge-and-listen; Kemsky for anyone with traditional wired headphones — and especially two people sharing one screen.
The Togconn Dual USB C is a 2-in-1 USB-C male to double USB-C splitter. In practice, that means you plug the male end into your device, then use one USB-C port for a USB-C headset and the other for a charger. The spec sheet lists PD 60W at 20V 3A, so it's built to pass serious charging power rather than trickle-charging your phone while you listen. It's plug and play — no driver, no software, no setup routine.
Build-wise, this is the more premium-feeling of the two. Togconn uses a metallic aluminum shell in space gray, and the listing says it's passed 10,000+ plug-and-unplug cycles. Aluminum helps with heat dissipation, which matters when you're pushing 60W through a dongle the size of a stick of gum. It weighs in at 0.01 kg, so it disappears in a pocket or a bag pocket. Togconn also backs it with a 24-month warranty and says questions get resolved within 24 hours — worth noting since this is a tiny accessory that lives a hard life in a bag.
Compatibility covers the modern USB-C world: iPhone 16, 16 Plus, 16 Pro and 16 Pro Max, the Galaxy S20 through S22 Ultra line, Galaxy Z Fold 3 and 4, Note 20, iPad Pro, and Pixel 4 and 3. The connector is listed as USB-C 3.1 with three ports total.
Who should buy it? If you already own a USB-C headset — or you're planning to move to one — and you're tired of choosing between charging and listening, this is the clean solution. Gamers who want low-latency USB-C audio while plugged into a charger will like it too. Who should skip it? Anyone whose headphones end in a 3.5mm plug. And if you want to share audio with a friend on a flight, this isn't the tool — there's only one audio path.
The Kemsky USB C Double attacks a completely different problem: your phone has no headphone jack, your nice wired headphones use 3.5mm, and you refuse to buy new headphones. This 3-in-1 adapter gives you dual 3.5mm jacks plus PD 60W charging, so you can listen, take calls, game, or watch video while the battery keeps climbing.
The headline feature is the built-in DAC chip, which Kemsky rates at up to 24bit/96kHz decoding — double the 16bit/48kHz that a lot of budget dongles settle for. Higher numbers here aren't just marketing decoration; a better DAC generally means cleaner decoding, stronger noise reduction and more faithful sound. Kemsky also states it won't harm your hearing, and that the charging chip negotiates the right voltage and current for each device — a sensible safeguard when you're feeding 60W through something this small.
Two 3.5mm jacks is the part people underestimate. That's a shared-listening device: two kids in the back seat on one tablet, a couple splitting a movie on a plane, a language learner and a tutor on one call, a gamer and a friend on the same console output. Very few adapters in this category offer that at all.
The housing is durable ABS rather than metal, which is corrosion-resistant and sturdy but won't feel as dense as aluminum. It's plug and play with no drivers, compact and light, and Kemsky provides a 12-month warranty with support until your issue is resolved. Compatibility is broad: iPhone 17 Pro Max / 17 Pro / 17 down through 16 series, Galaxy S26 Ultra / S26+ / S26 / S25 Ultra / S25+ / S25, Pixel 10 Pro through Pixel 6, HUAWEI Mate 60 Pro, MacBook Pro and Air 2024, iPad Pro and Air 2020–2024, XPS 17/15/13, Dell, HP Chromebook x360, Surface Book 3, Samsung Tablet S9, Note 20, LG V40, Valve Steam Deck and Switch 2.
Buy it if you live in the analog headphone world and want to keep it that way. Skip it if your headphones are USB-C — this adapter has no USB-C audio output for them, and its power plug type is listed as "No Plug," meaning it draws power from the connected device rather than a wall outlet.
Side-by-Side: Which Should You Choose?
• Best for traditional 3.5mm headphones → Kemsky USB C Double. Two analog jacks, no dongle-on-a-dongle stacking required.
• Best for shared listening → Kemsky USB C Double. Dual 3.5mm jacks let two people hear the same source; Togconn has a single audio path.
• Best for audio quality ambitions → Kemsky USB C Double. Its DAC is rated up to 24bit/96kHz versus the 16bit/48kHz typical of budget adapters, with noise reduction called out in the specs.
• Best for durability and feel → Togconn Dual USB C. Aluminum shell, metallic finish, and a claimed 10,000+ plug/unplug cycles.
• Best for long-term coverage → Togconn Dual USB C. 24-month warranty against Kemsky's 12 months.
• Best for gaming handhelds and consoles → Kemsky USB C Double. Steam Deck, Switch 2 and PS5 appear on its compatibility list, and dual analog jacks suit shared play.
• Best for charging power → a tie. Both are rated PD 60W, so neither wins on raw wattage.
If I had to buy one, I'd buy the Kemsky USB C Double — but only because of who I am as a buyer. I own analog headphones, I share a screen with someone else regularly, and the 24bit/96kHz DAC plus two jacks covers more of my real situations. That said, the Togconn Dual USB C is the smarter pick if you've moved to USB-C audio: aluminum build, a 24-month warranty, and a clean single-cable charge-and-listen solution. In my opinion, the deciding question isn't which is better — it's which plug your headphones have. Answer that honestly and the choice makes itself.
Only the Togconn Dual USB C. It's a USB-C male to double USB-C splitter, so one port takes your USB-C headset and the other takes your charger. The Kemsky USB C Double outputs to 3.5mm jacks, so USB-C headphones won't connect to it.
Can I charge and listen at the same time on both?
Yes. Both are rated for PD 60W (20V 3A) charging while audio plays, and both are plug and play with no drivers required. The difference is the audio connector, not the charging behavior.
Not universally. Its DAC is rated up to 24bit/96kHz, which is genuinely higher than the 16bit/48kHz typical of budget adapters and should mean cleaner decoding for analog headphones. But if your headphones are USB-C, the Kemsky can't help you at all — the Togconn is the correct adapter.
The Togconn lists an aluminum shell, a metallic finish, and 10,000+ plug/unplug cycles with a 24-month warranty. The Kemsky uses durable ABS and carries a 12-month warranty. On paper, Togconn makes the stronger durability claim, though both are built for daily carry.
