If you want a simple wired headset for a child or a shared device, choose noot products K11; if you need wireless open-ear listening with a call-focused microphone for webinars, choose RICHJOY Open Ear Earbuds. For webinars, RICHJOY is the more suitable pick because its ENC microphone is designed to reduce wind and background noise during calls; the K11 has no built-in microphone.
The trade-off is straightforward: the K11 uses a 3.5 mm cable and an adjustable on-ear fit, while RICHJOY connects by Bluetooth and clips around the ear. Neither is a conventional noise-canceling headset, so the better fit depends on whether you value wired simplicity or wireless calls and open-ear comfort.
• noot products K11: Its wired 3.5 mm connection, padded on-ear cushions, adjustable headband, and foldable design suit straightforward listening. Its biggest trade-off is that it has no built-in microphone.
• RICHJOY Open Ear Earbuds: Its Bluetooth 6.0 connection, open-ear clip-on design, ENC microphone, and stated 40-hour total playtime favor wireless calls and everyday movement. Its trade-off is that it does not plug into a headphone jack.
• Choose the K11 for a child-friendly wired headset, a compatible device with a 3.5 mm jack, or a foldable option for travel.
• Choose RICHJOY for Bluetooth listening, open-ear wear, and webinars where a built-in call microphone matters.
The K11 is a wired, on-ear headset with a 3.5 mm jack, padded cushions, an adjustable headband, and a foldable construction. That combination makes it a practical option for straightforward listening on a compatible tablet, laptop, Chromebook, or desktop computer. There is no pairing process or charging routine to manage: connect the cable to a 3.5 mm socket and use the headset. The supplied information also lists volume control, which is useful when the listener needs a direct way to adjust sound.
Its lightweight design and adjustable band are intended to fit children and can also accommodate adults. That makes the K11 a reasonable shared headset for household devices, schoolwork, or entertainment during travel. Foldability helps when it needs to be packed away, and the 24-month warranty is a relevant ownership detail for someone buying a headset for regular family use. Its 5-foot cord gives the listener some room to sit back from a device, although a cable is still something to manage at a desk or in a bag.

The defining limitation is important: the K11 has no built-in microphone. A listener may be able to speak through the microphone on the connected device, but that is not the same as having a mic on the headset. I would not choose it as a noise canceling gaming headset for webinars or as the best with microphone in ear earbuds for webinars. It is for listening, not for a headset-based conversation. Some newer devices also need an appropriate adapter to use its 3.5 mm plug, so check the device connection before choosing it.
Who should skip it: Skip the K11 if you need a built-in microphone, wireless listening, or a headset that connects without a 3.5 mm jack.
RICHJOY takes a very different approach. These are wireless, open-ear clip-on earbuds with a C-shaped design, Bluetooth 6.0, and touch controls. The open-ear placement avoids putting an earbud tip inside the ear canal, while the clip-on shape is designed to sit securely around the ear. Each earbud is listed at 4.8 grams, so the design is aimed at lightweight wear during activities such as commuting, working from home, or exercising.
For calls, the feature that matters most is the built-in ENC microphone. The product information describes it as using environmental noise cancellation to reduce wind and background noise during calls. That makes RICHJOY the more relevant of these two products for webinars and online meetings. It is not a guarantee that every call will sound clear in every room, but it does include a call-focused microphone; the K11 does not. If you are searching for noise cancelling wireless headphones for webinars, note the distinction: ENC is described for microphone calls, not as active noise cancellation that silences what you hear around you.
The earbuds have no headphone jack, so they rely on Bluetooth pairing with a compatible phone, tablet, PC, or other Bluetooth device. They are listed with up to 40 hours of total playtime with the charging case, and the case has a screen that displays battery levels. That can be helpful for planning use between charges, though the stated total includes the case rather than describing a single uninterrupted earbud session. IPX5 protection is listed for sweat, rain, and splashes, which supports use during workouts or in wet conditions without making them a general-purpose waterproof device.
Who should skip it: Skip RICHJOY if you need a wired 3.5 mm connection, prefer an on-ear headset, or want strong isolation from surrounding sound.
Side-by-Side: Which Should You Choose?
• Best for a simple wired setup → noot products K11. Its 3.5 mm plug avoids Bluetooth pairing and charging, provided the device has a compatible jack.
• Best for open-ear wear → RICHJOY. Its C-shaped clip-on design sits around the ear rather than over it or inside the ear canal.
• Best for a child-focused, adjustable headset → K11. Its on-ear padded design and adjustable headband are described as suitable for children and adults.
• Best for a foldable travel headset → K11. The foldable construction is useful when packing it with a tablet or laptop; the 5-foot cord is the main cable to manage.
• Best for wireless movement and workouts → RICHJOY. Bluetooth connection, clip-on fit, and listed IPX5 sweat and splash protection make it better suited to active use.
• Best for knowing the case battery level → RICHJOY. Its charging case has a display for real-time battery levels, alongside a stated total playtime of up to 40 hours with the case.
• Best for listening without a built-in mic requirement → K11. For calls, however, consider whether the connected device’s own microphone is suitable for the way you plan to use it.
I would choose RICHJOY Open Ear Earbuds for webinars because a built-in ENC microphone gives them a clear advantage for calls over the K11, which has no microphone. The open-ear design, Bluetooth connection, and case battery display also make RICHJOY the more flexible option for moving between meetings and everyday listening. I would choose the K11 instead for a child or anyone who wants a simple wired headset for listening on a device with a 3.5 mm jack.
Before choosing, check how you plan to connect. The K11 uses a 3.5 mm plug; some devices require an adapter, and the product information specifically notes adapter needs for certain iPad Pro and iPhone models. RICHJOY uses Bluetooth, so confirm that the device supports Bluetooth audio. Its listed compatibility includes iPhone, Android, iPad, and PC.
Think about whether a microphone is essential. The K11 has none built into the headset, while RICHJOY includes an ENC microphone intended to reduce background noise on calls. If your webinars involve frequent speaking, that difference is more consequential than the K11’s foldable design or the RICHJOY case display.
