If you want a dedicated USB-C charging set for compatible Sony headphones, earbuds, or speakers for swimming trips, choose FTUINL 6FT; if you need a USB-C adapter for wired headphones and charging at the same time, choose Vcddom USB C. These are not interchangeable accessories: one is a cable and charger block, while the other splits a USB-C connection into audio and charging.
FTUINL 6FT vs Vcddom USB C at a Glance
• FTUINL 6FT’s biggest strength: It comes with a roughly 6.6-foot USB-C cable and a 20W charger block. Trade-off: Its listed compatibility is focused on specified Sony headphones, earbuds, and speakers.
• Vcddom USB C’s biggest strength: It combines two 3.5mm headphone jacks with a USB-C charging port rated for up to 60W PD3.0 charging. Trade-off: It is an audio adapter, not a replacement USB-C charging cable set for Sony gear.
• Choose FTUINL 6FT if you need a longer charging cable and charger for compatible Sony devices.
• Choose Vcddom USB C if you want wired 3.5mm headphones and charging connected to a compatible USB-C device at the same time.
• Neither is itself a swimming headphone. For swimming, confirm that your audio device is designed for the water; these accessories address charging or wired audio connections, not water protection.
FTUINL 6FT is the straightforward option when the job is charging a compatible Sony device. The set includes a USB-C cable measuring approximately 6.6 feet, or 2 meters, and a 20W charger block with one port. That extra cable length can be useful when the outlet is farther from a desk, bedside table, or travel spot than a short cable comfortably reaches.
The listed compatible products include Sony WH-1000XM4 and WH-1000XM5 headphones, CH720N and CH520 headphones, WF-1000XM5 and several other Sony earbuds, and selected Sony speakers. The maker states that the charger can deliver 20W and describes charging earbuds from empty to 80% in 30 minutes. Treat that as a stated charging claim, not a guarantee for every listed device or charging situation.
I would consider FTUINL if I needed a dedicated charging set for one of the specified Sony products and wanted a cable longer than a typical short lead. I would skip it if I needed a 3.5mm audio connection, a splitter for two wired headphones, or broad device support beyond the Sony models listed. It does not add listening features, and it is not a swimming accessory in the sense of being an underwater audio device.
That distinction matters if you are searching for bluetooth earbuds for swimming. FTUINL is a charger for compatible earbuds and other Sony products; it does not provide Bluetooth, audio playback, or water resistance. It may be useful for charging suitable gear before or after a swim, but the charging set itself does not establish that the device you connect is safe to use in water.
Vcddom USB C is built for a different problem: connecting wired 3.5mm headphones to a USB-C device while keeping a USB-C charging connection available. It has two 3.5mm headphone jacks, so two compatible wired headphones can share audio, plus a USB-C port for charging. The product information lists support for inline volume control and call management with compatible headphones.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Its charging capability is specified as up to 60W PD3.0, and the product description recommends using a PD wall charger for faster charging. The adapter also lists a DAC supporting 24-bit, 96 kHz stereo audio and compatibility with both CTIA and OMTP headphone wiring. Those details make it more relevant to phones, tablets, and computers with USB-C connections than to charging a standalone set of Sony earbuds.
The listed device families include selected iPhone, iPad, Samsung Galaxy, and Google Pixel models, along with some computers. Compatibility is not universal merely because a device has USB-C, so I would check the exact device and headphone setup before choosing it. Its main trade-off is also clear: the two 3.5mm jacks do not make it a Bluetooth product, and the adapter does not include a long charging cable or a charger block.
For someone looking for the best rechargeable open ear headphones for swimming or the best ear clip headphones for swimming, Vcddom is not that product. It is an audio-and-charging adapter for wired headphones, not a set of ear clips or open-ear headphones. It can make sense for everyday listening, a commute, or sharing audio, but nothing in its listed features makes it suitable for swimming or establishes water protection.
• Need a USB-C cable and charger block for compatible Sony gear → FTUINL 6FT. It includes both, with a cable approximately 6.6 feet long and a 20W charger block.
• Need two wired headphone connections from one USB-C adapter → Vcddom USB C. Its dual 3.5mm jacks are the defining feature.
• Want to charge while listening through wired headphones → Vcddom USB C. It provides a USB-C charging port alongside its audio connections.
• Want a longer cable for a charging setup → FTUINL 6FT. Its cable is approximately 2 meters long.
• Need an accessory for specified Sony headphones, earbuds, or speakers → FTUINL 6FT. Check the model against its compatibility list rather than assuming every Sony product is covered.
• Want to connect compatible USB-C phones, tablets, or computers to wired headphones → Vcddom USB C. The listed compatibility includes selected products from several device families.
• Need an accessory specifically for swimming → Neither. Neither product is presented as swimming headphones or as water-protection equipment.
• Need charging power specified above 20W → Vcddom USB C, with a caveat. Its charging port is rated up to 60W PD3.0, but actual charging depends on the connected device and charger. FTUINL’s charger block is specified as 20W.
The distinction between a charger and an adapter is more important than the difference between their connector styles. FTUINL is a charging set: plug its cable into the included block to charge compatible devices. Vcddom is a multifunction adapter: plug it into a compatible USB-C device to add wired audio jacks and a separate charging port.
That means the products answer different questions. If your problem is “How do I charge these listed Sony earbuds or headphones from an outlet with a longer cable?” FTUINL is the direct fit. If the problem is “How can I listen through wired 3.5mm headphones while my USB-C device charges?” Vcddom is the more relevant tool.
Neither product should be treated as a substitute for swimming-specific audio equipment. Charging a device before swimming does not make it water-safe, and an audio adapter that supports wired headphones does not make those headphones appropriate for water. For swimming, check the specifications of the actual listening device and use accessories only in the conditions they are designed for.
There is also a practical difference in what comes in the box. FTUINL lists one USB-C cable and one 20W charger block. Vcddom is the adapter itself, with its dual headphone jacks and charging pass-through described as part of the unit. If you need a wall charger or a longer USB-C cable for Vcddom, those are not included among the listed contents.
The audio figures are relevant only to the Vcddom use case. Its 24-bit, 96 kHz DAC specification concerns audio passing through the adapter; it does not tell you how comfortable or durable a pair of headphones will be. Likewise, FTUINL’s stated charging speed is not an audio feature. Comparing them as though they were two competing headphone products would lead to the wrong purchase.
My Verdict
In my opinion, I would choose FTUINL 6FT if my priority were charging a compatible Sony device, because its included 20W block and approximately 6.6-foot cable make that purpose clear. For swimming, I would treat it only as a charging accessory and choose a separate device specifically suited to water use. I would pick Vcddom instead for wired listening and charging through a compatible USB-C phone or tablet.
Neither is a swimming headphone or a product with stated water protection. FTUINL is a charger set for specified Sony devices; Vcddom is a wired-audio and charging adapter. Choose listening equipment based on its own suitability for water.
It has a USB-C charging port alongside two 3.5mm headphone jacks, allowing charging and wired audio at the same time on a compatible device. Its charging capability is listed as up to 60W PD3.0, and a PD wall charger is recommended for faster charging.
No universal compatibility is stated. The listed models include selected Sony headphones, earbuds, and speakers, such as WH-1000XM4, WH-1000XM5, WF-1000XM5, CH520, and CH720N. Check your exact model against the compatibility information before buying.
Choose Vcddom USB C if your device is compatible and your headphones use a 3.5mm plug. It provides two headphone jacks and a USB-C charging port. FTUINL is the better match for charging the specified Sony products, not for adding wired audio connections.
