If you want to keep using one wired headphone while charging and moving data at the same time, choose Pubiohs USBC Splitter 1; if you need a compact 20W wall charger built around Beats earbuds and headphones, choose zonbto 20W. These two accessories solve completely different problems, and the "versus" framing only makes sense once you know which job you actually have. One is an audio-and-charging splitter with a DAC inside. The other is a plug-and-go power adapter. Below I break down what the spec sheets actually tell a buyer.
• Pubiohs USBC Splitter 1 — biggest strength: it splits one USB-C male connector into a 3.5mm audio jack, a USB-C headphone/data jack, and a USB-C charging port, with a built-in DAC rated up to 32-bit/384kHz for HiFi-grade audio and data transfer alongside charging.
• Pubiohs USBC Splitter 1 — biggest trade-off: it only works with digital headphones, and you can only use one audio jack plus the charging jack at a time — two audio jacks at once means silence. It also won't handle 100W fast charging, so laptops and iPad Pro are off the table.
• zonbto 20W — biggest strength: a 20W USB-C wall adapter with overcharge, high-voltage, current-regulation and temperature protection, in a lightweight 2-ounce body with a standard North American two-pin plug.
• zonbto 20W — biggest trade-off: it's a charger only. No cable in the box, no audio passthrough, no data-transfer function, and one USB-C port total.
• Who each pick is for: Pubiohs for someone who wants to listen and charge (and move data) from the same USB-C device with a wired digital headset; zonbto for someone who owns Beats earbuds or headphones and just wants a small, safety-focused 20W charger for the wall.
This is a 1-in-2-out splitter — the male USB-C end fans out into three female outputs: a 3.5mm audio jack, a USB-C headphone jack that also carries data, and a USB-C charging port. The point of the design is that you keep your wired headset plugged in while the phone or tablet tops up. It supports microphone function and volume adjustment, so calls and voice chat work, not just music. There's also a dual-input design — USB-C and Lightning — which is why the compatibility list stretches across iPhone 7 and 8 up through the iPhone 17 family, plus most USB-C Android devices.
Who should buy it: anyone with digital USB-C headphones who wants one adapter that handles listening, charging, calls and file transfer at the same time. Who should skip it: anyone with analog headphones. The compatibility note is blunt — if your headphone isn't recognized as an external USB audio device on a digital-audio-only device like a USB-C iPad Pro or MacBook, it won't work here. Also skip it if you expect to run two headsets at once, if you need 100W laptop charging, or if you want to power a speaker through it. And budget a minute for setup: on iPads, tablets, laptops and MacBooks you have to manually select "USB Audio 2.0" the first time, because these devices default to their own audio output.
zonbto 20W: Who It's For
The zonbto 20W is a single-port USB-C wall charger with a Type A two-pin North American plug, finished in black, and it weighs about 2 ounces. That's the whole product — and for a lot of people that's the whole point. It's built around Beats audio gear specifically: Powerbeats Pro 2, Solo 4, Solo Buds, Studio Pro, Studio Buds and Studio Buds +, Fit Pro (including the Kim Kardashian edition), the new Flex, and the Pill 2024 speaker are all named in the compatibility list. If you own any of those, this is a matching power source rather than a guessing game.
The safety package is the most substantive part of the spec sheet. zonbto lists overcharging protection, high-voltage protection, current regulation and temperature control as a combined system. For earbuds and headphones that sit on a charger overnight, that combination matters more than raw wattage — it's the difference between a charger you leave plugged in without thinking and one you unplug every time. At 20W it's sensibly matched to small-battery audio devices rather than laptops.
Who should buy it: Beats owners who want a small, pocketable 20W adapter with a named-device compatibility list and a multi-layer protection system. Travelers will like the 2-ounce weight. Who should skip it: anyone who needs to charge a laptop, anyone who wants multiple ports, and anyone expecting a cable in the box — it doesn't include one, so you'll need your own USB-C cable to actually use it. If you were hoping for audio passthrough or data transfer, that's not this product; that's the Pubiohs.
• Best for listening while charging → Pubiohs USBC Splitter 1. It's the only one of the two with an audio path at all.
• Best for audio quality → Pubiohs USBC Splitter 1. The DAC is rated to 32-bit/384kHz, above the 24-bit/96kHz ceiling the brand calls out as typical.
• Best for data transfer → Pubiohs USBC Splitter 1. Moving files while charging or listening is a stated core function; the zonbto has no data feature.
• Best for charging speed on small devices → zonbto 20W. A focused 20W output versus the Pubiohs's 10W charging port.
• Best for safety features → zonbto 20W. Overcharge, high-voltage, current regulation and temperature control are all listed.
• Best for Beats owners → zonbto 20W. The compatibility list is built around Beats earbuds, headphones and the Pill 2024.
• Best for travel weight → zonbto 20W. About 2 ounces and pocket-sized; the Pubiohs is a cable-format adapter, not a plug.
• Best for iPhone and Android flexibility → Pubiohs USBC Splitter 1. Dual USB-C and Lightning input covers a very wide phone range.
• Best if you own analog headphones → neither, honestly. The Pubiohs requires digital headphones, and the zonbto doesn't do audio at all.
In my opinion, most people searching this comparison should buy the Pubiohs USBC Splitter 1 — but only after checking one thing: that their headphones are digital. If they are, you get HiFi-grade audio, mic support, data transfer and charging from one adapter, which is genuinely hard to find in a single product. If your headphones are analog, or if your real need is simply a small, safe 20W wall charger for Beats gear, then the zonbto 20W is the cleaner, simpler purchase and I'd recommend it without hesitation for that job. Two different tools. Buy the one that matches the problem in front of you, and check the current price on Amazon before you commit.
For iPhone users with digital USB-C or Lightning headphones, yes — the compatibility list runs from iPhone 7 and 8 up through the iPhone 17 series, and the adapter supports mic and volume control. Just remember it won't do 100W charging, so don't expect it to power a laptop.
Yes, that's its main purpose — one audio jack plus the charging port together. What it can't do is run two audio jacks simultaneously; if you connect two headphones at once, you'll hear nothing. It also doesn't support charging speakers.
No. The package is the 20W USB-C wall adapter only, and the spec sheet states a charging cable is not included. You'll need your own USB-C cable to use it, and it's designed around Beats earbuds, headphones and the Pill 2024 speaker.
The Pubiohs USBC Splitter 1, as long as your headphones are digital. The zonbto 20W has no audio or data function at all — it's a single-port wall charger. If you want both capabilities, the splitter is the only one of the two that can do it.
