If you want a simple wired headset for a child listening on dry land, choose noot products K11; if you need tiny, wireless earbuds for sleep and everyday wear, choose wedoking Smallest Invisible Sleep. For swimming, choose neither: the Wedoking earbuds are explicitly not for swimming or diving, and the K11 has no stated water-resistance rating.
These products solve very different problems. The K11 is an adjustable, foldable on-ear headphone with a 3.5 mm plug. The Wedoking is a small Bluetooth earbud set built around a low-profile fit and passive noise blocking—not active noise cancelling.
• noot products K11 strength: Simple wired audio, a 5-foot cord, adjustable on-ear fit, and foldable storage. Trade-off: it is not wireless, and no water-resistance rating is provided.
• wedoking Smallest Invisible Sleep strength: Compact wireless earbuds with three sizes of tips and caps, plus a design intended to sit comfortably for side sleepers. Trade-off: IPX6 is for the earbuds only, and the product is specifically not for swimming or diving.
• Noise handling: Wedoking forms a passive seal rated to block outside noise by up to 24 dB; it does not have ANC. K11 lists sound isolation but provides no comparable decibel figure.
• Battery and connection: Wedoking offers up to four hours from the earbuds and up to 20 additional hours from the case, using Bluetooth. K11 runs through its 3.5 mm wired connection and needs no earbud charging.
• Who each suits: K11 is the more straightforward pick for a child using a compatible device on land; Wedoking is for an adult who wants tiny wireless earbuds for sleep or daily listening.
K11 is a wired, on-ear headset with a 3.5 mm jack, a 5-foot cord, padded cushions, and an adjustable headband. Its foldable construction makes it easier to stow for travel than a rigid headset. The listed frequency range is 1 Hz to 20,000 Hz, with a 32-ohm impedance and a dynamic driver. It also includes a volume control.

For swimming, skip the K11. Its wired, on-ear design is not presented as water-resistant, so there is no basis to treat it as swim gear. It may suit ordinary listening on an airplane or during a dry commute, but it does not offer the wireless, low-profile fit that makes the Wedoking more appealing for sleep.
Wedoking’s earbuds are designed to sit close to the ear, with soft silicone tips and ear caps in three sizes. That gives shoppers some room to adjust the fit, which matters for a product intended for side sleeping. Each earbud weighs 2.0 g without its tip and wing tip, according to the product details. The set connects over Bluetooth and includes built-in microphones.
Its noise blocking is passive: the earbuds form a seal, with the stated blocking figure reaching up to 24 dB. That is not active noise cancelling. Someone specifically searching for the best active noise cancelling true wireless earbuds for swimming should note both limits: these earbuds do not have ANC, and their IPX6 rating is not a swimming or diving rating.
The claimed battery life is up to four hours per earbud charge, with up to 20 additional hours from the case. IPX6 protection applies to the earbuds, for sweat and splashing—not immersion. That makes them more relevant to sleep, office use, or a workout than to swimming. If your main goal is the best extra bass earphones for swimming, neither product’s supplied information establishes a bass-focused tuning or suitability for pool use. And while the Wedoking has a stated case-assisted listening duration, it is not a bone-conduction design, so it cannot answer a search for the best long battery life bone conduction headphones for swimming.
Side-by-Side: Which Should You Choose?
• Best for a child using a wired tablet or computer → noot products K11. It has a 3.5 mm connector and an adjustable on-ear headband. Check whether a device without a headphone jack needs an adapter.
• Best if you want to avoid charging earbuds → noot products K11. It uses a wired connection, while Wedoking relies on its earbuds and charging case.
• Best for a wireless connection → Wedoking Smallest Invisible Sleep. It connects by Bluetooth and includes microphones; K11 is wired and has no built-in mic.
• Best for stated passive noise blocking → Wedoking Smallest Invisible Sleep. The listed figure is up to 24 dB, but that is passive isolation, not ANC. K11 lists sound isolation without a comparable measurement.
• Best for a foldable travel headset → noot products K11. Its on-ear headphones fold for storage and have a 5-foot cord.
• Best for a workout involving sweat or splashes → Wedoking Smallest Invisible Sleep, with limits. The earbuds are rated IPX6, but the rating does not make them suitable for swimming or diving.
• Best for swimming → neither. Wedoking explicitly excludes swimming and diving; K11 has no water-resistance information.
I would choose the Wedoking for sleep and everyday wireless listening, because its low-profile fit, adjustable tip options, and case-assisted battery life match those uses better.
I would choose the K11 for a child who needs a simple wired headset for a compatible device.
For swimming, I recommend neither: the Wedoking is not intended for it, and the K11 has no stated water protection.
If swimming is the priority, look for a product whose specifications explicitly support that use.
No. They have an IPX6 rating for the earbuds, but the product information says they are not for swimming or diving. Treat the rating as protection against sweat and splashing, not immersion.
No. They use a snug fit to provide passive noise blocking, stated as up to 24 dB. That is different from electronic active noise cancelling.
The K11 is wired, so it does not have a rechargeable earbud battery. Wedoking lists up to four hours for the earbuds and up to 20 additional hours from the charging case; those figures describe different parts of its battery setup.
The K11 connects through a 3.5 mm jack. Devices without that port may require a compatible adapter, and the adapter type depends on the device’s connection.
