If you want a simple wired volume-control setup for Switch, choose Koss 155954; if you need child-focused, foldable headphones for Switch, choose ONTA Kids Headphones. The key distinction is that the Koss is a volume-control cord, not a complete headset, while ONTA is a pair of wired headphones.
If you want a simple wired volume-control setup for Switch, choose Koss 155954; if you need child-focused, foldable headphones for Switch, choose ONTA Kids Headphones. The key distinction is that Koss is a volume-control cord, not a complete headset, while ONTA is a pair of wired headphones.
For Switch use, that difference matters: Koss needs headphones of your own, while ONTA supplies the headphones but has no volume control listed. Neither product offers Bluetooth or noise control.
Koss 155954 vs ONTA Kids Headphones at a Glance
• Koss 155954’s biggest strength: a wired volume-control accessory with a clip and a 39-inch cord. Trade-off: it is not a headset, so you must supply compatible headphones.
• ONTA Kids Headphones’ biggest strength: adjustable, foldable, child-focused headphones with removable padding. Trade-off: the listed controls do not include a dedicated volume adjustment, and the cable is wired.
• Choose Koss if you already have headphones with a 3.5 mm plug and want a physical volume control positioned nearby.
• Choose ONTA if you need a complete over-ear headphone set for a child and value portability and an adjustable headband.
• For Switch, both products connect through a 3.5 mm headphone jack; neither is a multipoint headset or a wireless option.
The Koss 155954 is the VC20 volume-control cord. It connects between compatible headphones and a device’s 3.5 mm headphone output, giving you a separate control for adjusting listening level. That can be useful with a Switch when you want to change volume without reaching for the console’s own controls. The 39-inch cord gives the accessory some reach, and its pocket or belt clip lets you position the control where it is convenient.
This is a practical choice for someone who already owns wired headphones they like. The connector works with 3.5 mm plugs, and the product information describes compatibility with portable music devices and cell phones. The stated lifetime warranty is another relevant detail for buyers considering a small accessory they may keep with their headphones over time. It is not a wireless adapter, however: the connection is wired, and the product’s job is volume adjustment rather than sound reproduction.

The biggest limitation is easy to overlook if you are shopping for a headset: Koss 155954 does not include headphones. You need a compatible pair, and the available information does not describe a microphone, noise control, or a headset-style headband. It may suit someone searching for a volume-control accessory for Switch, but it is not itself a neckband headphones for Switch option or a complete open-ear headphone system.
Who should skip it: Skip Koss 155954 if you need a complete headphone set, wireless listening, or an included headset microphone.
ONTA Kids Headphones are a wired, over-ear set designed for children. The headband adjusts, so it can accommodate a range of head sizes as a child grows. The headphones fold for storage, and the padding is removable for cleaning. Those details suit everyday situations such as carrying a pair in a school bag, putting them away after a game, or packing them for a trip.
For Switch, ONTA provides the headphones themselves and connects through a 3.5 mm jack. The listed audio specifications include a dynamic driver, a 20 Hz–20 kHz frequency range, and 103 dB sensitivity. These figures describe the audio hardware; they do not establish how comfortable a particular child will find the fit or how loud the headphones will seem in every situation. The product information also lists media control, but does not specify a separate volume-control feature, so do not assume it offers the same adjustment function as the Koss cord.
Its child-oriented design is the main reason to consider it over an accessory. The flexible headband and adjustable fit are meant to suit children, while the foldable construction and removable padding are useful features for storage and upkeep. The trade-offs are that it remains a wired headset, and its listed noise control is none. The product description discusses child-focused materials and design, but it does not provide a Switch-specific feature set or establish that the headphones limit listening volume.
Who should skip it: Skip ONTA if you need a separate inline volume control, Bluetooth, or noise control.
• Best for a volume control placed on the cable → Koss 155954. It is specifically a volume-control accessory and includes a clip for positioning it on a pocket or belt.
• Best for a complete child-sized headphone set → ONTA Kids Headphones. It includes adjustable over-ear headphones rather than just a cord.
• Best if you already own wired headphones → Koss 155954. Its purpose is to add convenient level adjustment to compatible headphones with a 3.5 mm connection.
• Best for folding and packing away → ONTA Kids Headphones. The headphones fold, and their padding can be removed for cleaning.
• Best for a Switch user who wants a wired setup → Either, with a caveat. Both use a 3.5 mm connection, but Koss requires your own headphones and ONTA does not list a dedicated volume adjustment.
• Best for long-term fit as a child grows → ONTA Kids Headphones. Its adjustable headband is intended to accommodate children of different ages.
• Best for someone seeking the best multipoint headset for Switch → Neither. Both are wired, and neither product’s listed features include multipoint connectivity.
• Best for a neckband headphones for Switch search → Neither. Koss is a clip-on volume-control cord, while ONTA is an over-ear headphone set.
• Best for a best open ear headphones for Switch search → Neither. ONTA is over-ear, and Koss is an accessory rather than an open-ear headset.
In my opinion, I would choose ONTA Kids Headphones for a child who needs a complete wired headset for Switch, because the adjustable headband, folding design, and removable padding serve everyday use directly. For a setup built around headphones you already own, Koss 155954 is the more focused tool: it adds an inline volume control and a clip.
For Switch, my pick is ONTA if the child needs headphones; I’d choose Koss only when adding volume adjustment to an existing wired pair is the main goal.
Start by checking what you already have. If you have comfortable headphones with a 3.5 mm plug and want a separate control for adjusting volume, Koss may fill that specific gap. If you do not already have headphones, it will not complete your setup on its own. ONTA is the more straightforward choice when the goal is to get a wired, child-focused headphone set in one product.
Next, decide whether a physical volume control is essential. Koss lists volume control as its function. ONTA lists media control, but the supplied information does not specify a dedicated volume adjustment. If you want a control on the cable, that distinction should guide your choice rather than assuming both products work the same way.
Fit and portability point in a different direction. ONTA has an adjustable headband, folds for storage, and has removable padding. Those features may be useful for school bags, travel, and cleaning. Koss is far smaller in purpose: its clip helps place the control within reach, but it does not provide the headband, earcups, or padding of a headphone set.
Finally, neither product is described as wireless or as having noise control. Both use a wired 3.5 mm connection, so consider whether that matches the way you plan to play. If you want Bluetooth, multipoint connections, or an open-ear design, these two products do not offer those listed characteristics.
