If you want a premium, noise-canceling over-ear experience with deep bass and long battery life for immersive listening, choose CMF BY NOTHING Headphone Pro Active; if you need lightweight, open-ear comfort that keeps you aware of your surroundings while running or studying, choose LC-dolida Open-Ear. This isn't about which pair is "better" in a vacuum, but which design actually fits the specific way you listen. One is built for total immersion, while the other is engineered for safety and all-day wear without blocking out the world.
• CMF BY NOTHING Headphone Pro Active: Delivers 40 dB of adaptive noise cancellation and Hi-Res audio via LDAC, but its over-ear design blocks ambient sound entirely. Best for commuters, gamers, and anyone seeking studio-quality sound isolation.
• LC-dolida Open-Ear: Offers an open-clip design with zero ear fatigue and a smart LED case for controls, but lacks active noise cancellation and has a lower frequency range. Best for outdoor runners, cyclists, and those who prioritize situational awareness.
• The Verdict: If you are looking for the best gaming headset for children who need to focus on game audio without distraction, the CMF model wins. If you need in ear headphones for children that allow them to hear traffic or teachers, the LC-dolida option is the safer choice.
The CMF BY NOTHING Headphone Pro Active is a powerhouse designed for those who demand high fidelity and total control over their audio environment. At its core, this is an over-the-ear device built around a custom 40mm dynamic driver that supports LDAC and dual Hi-Res certification. This means it can reproduce audio frequencies ranging from 20Hz up to 40kHz, capturing details that standard Bluetooth codecs simply miss. For a parent shopping for the best on ear headphones for children who love video games or music production, the clarity provided by this driver size and frequency response is significant. The soundstage is optimized for cinema and concert modes, offering a width and depth that makes virtual environments feel real.
Beyond the audio quality, the standout feature here is the 40 dB of Adaptive Active Noise Cancellation (ANC). This hybrid system actively filters out background noise, allowing the user to immerse themselves completely in what they are hearing. Whether it is a noisy classroom, a busy household, or a loud commute, the ANC creates a quiet sanctuary. There is also a Transparency Mode if you need to hear your surroundings instantly, but the primary design intent is isolation. The battery life backs up this heavy-duty usage with up to 50 hours of playback with ANC enabled, or a staggering 100 hours if you turn the noise cancellation off. A quick five-minute charge provides four hours of listening time, which is crucial for long study sessions or marathon gaming.

However, this level of performance comes with trade-offs. The physical design is an over-ear enclosure made of faux leather and plastic, weighing 283 grams. While it features memory foam earpads and a cap-friendly headband for comfort, it does cover the ears entirely. This makes it unsuitable for activities where hearing ambient noise is critical for safety, such as jogging near traffic or cycling in a city. It is also not designed for kids who might be sensitive to the pressure of clamping force over the ears for extended periods. If your child needs headphones that stay on during rough play or require them to remain fully aware of their immediate environment, this model is too isolating. It is strictly for stationary or low-movement listening where sound quality and silence are the priorities.
The LC-dolida Open-Ear takes a completely different approach, prioritizing comfort and situational awareness over raw power. These are clip-on earbuds that sit outside the ear canal rather than inside it. Constructed from liquid silicone, they offer a pressure-free fit that eliminates the ear fatigue common with traditional in-ear models. Because they do not seal the ear, users can hear traffic, conversations, and environmental cues while still enjoying music or taking calls. This makes them an ideal candidate for in ear headphones for children who are active outdoors, ensuring they never lose contact with their surroundings. The open-ear design prevents the buildup of heat and moisture, making them comfortable for all-day wear during school, commuting, or workouts.
What sets these apart from most open-ear competitors is the integration of the charging case as a smart control hub. Instead of relying on a smartphone app to adjust settings, the case features a built-in LED display that acts as a remote control. You can check the battery percentage, adjust volume, switch EQ modes, set timers, and even trigger your phone's camera directly from the case buttons. This removes the friction of downloading software or managing permissions, which is a practical advantage for younger users or parents who prefer simplicity. The connectivity relies on Bluetooth 5.0, providing a stable wireless connection with a range of up to 10 meters. While the frequency response is limited to 20Hz–20,000Hz compared to the extended range of the CMF model, the sound remains balanced and clear enough for voice calls and general media consumption.
The trade-off is clear: there is no active noise cancellation. The "None" rating in the noise control section means you cannot block out the world. In a quiet room, this is fine, but in a noisy environment, the audio will compete with background noise. Additionally, the battery life is rated at 30 hours total, which is decent but significantly less than the 100-hour potential of the over-ear alternative. The clip-on design ensures a secure fit for movement, but some users might find the sensation of having hardware resting on the outer ear different from a traditional headphone. It is also worth noting that long hair can occasionally activate the sensors, requiring careful positioning. This product is perfect for someone who values freedom of movement and wants a device that stays on their head without causing discomfort, but it sacrifices the deep, immersive bass and isolation of a closed-back system.

In my opinion, if I were buying headphones specifically for a child, the decision would hinge entirely on how they plan to use them. For a child who spends hours gaming, studying in a busy house, or traveling, I would choose the CMF BY NOTHING Headphone Pro Active. The combination of Hi-Res audio, spatial sound, and 40 dB noise cancellation creates an environment where they can truly focus and enjoy high-quality media without distractions. It is the superior choice for the best gaming headset for children because the isolation helps them tune into the game world completely. However, if the child is active, runs to school, or needs to hear their parents calling them from another room, I would pivot to the LC-dolida Open-Ear. Its open design is safer and more practical for an active lifestyle. Ultimately, the CMF model wins on pure performance and features, while the LC-dolida wins on versatility and safety.
Both products list an age range description of "Adult" in their technical specifications, so parental discretion is advised regarding fit and durability for smaller heads. However, the LC-dolida's open design is often preferred for safety, while the CMF offers better noise isolation for focused tasks.
No, the LC-dolida Open-Ear is designed to work without an app. Volume, EQ, and timer settings can be managed directly through the buttons on the smart LED display case.
Yes, the Hybrid Noise Cancellation on the CMF model helps filter out background noise, improving call clarity in loud settings, whereas the LC-dolida has no noise control.
The CMF BY NOTHING Headphone Pro Active is the winner with up to 100 hours of playback when ANC is off, compared to the 30-hour average life of the LC-dolida Open-Ear.
