If you want durable, comfortable headphones designed for long listening sessions with a secure fit that accommodates larger head sizes, choose ELECDER i37; if you need high-volume, disposable earbuds for classroom distribution or temporary use where replacement is the norm, choose QIDAIZUOEN 100.
• ELECDER i37: Best strength is its plush on-ear design and foldable durability for personal, long-term use; biggest trade-off is the lack of wireless connectivity or built-in microphone.
• QIDAIZUOEN 100: Best strength is the bulk value of 100 individually wrapped units with extra-small ear caps for various ear sizes; biggest trade-off is the basic in-ear build with no noise isolation and short warranty coverage.
• Who it's for: The i37 is for parents buying a dedicated pair for a child with big ears or an adult needing reliable wired audio, while the 100 pack is for teachers, event planners, or anyone needing instant, single-use solutions.
The ELECDER i37 stands out immediately because of its physical construction and intended lifespan. This isn't a throwaway item; it is engineered as a piece of personal equipment meant to survive the rigors of daily school life, travel, and extended gaming sessions. The defining feature here is the "On Ear" placement combined with plush materials. Unlike cheap plastic earpieces that dig into the cartilage, these utilize soft padding to distribute pressure evenly across the outer ear. This design choice is critical for anyone with bigger ears or a larger head circumference, as the adjustable headband can stretch to accommodate growth without pinching or causing fatigue after an hour of use.
In terms of utility, the i37 is a versatile wired companion. It features a standard 3.5 mm L-shaped stereo plug that fits almost every device from Chromebooks and laptops to tablets and older smartphones. The frequency range of 20 Hz to 20,000 Hz ensures a full spectrum of sound, delivering clear highs and decent lows through its dynamic drivers. While it lacks Bluetooth, the wired connection guarantees zero latency, which is essential for students watching educational videos or playing VR games where audio sync matters. The foldable design also makes it compact enough to slip into a backpack or suitcase, protecting the unit from damage during transit.

However, this product has clear boundaries. It is not for those seeking the convenience of wireless freedom or active noise cancellation. The control method relies entirely on the connected device, meaning there are no remote buttons on the cable itself to manage volume or calls. Furthermore, it does not include a built-in microphone, so it cannot be used for voice chats or hands-free calling. If your primary need is a simple, robust pair of headphones that stays on securely during movement and offers comfort for extended periods, the i37 is a strong contender. But if you need a headset for conference calls or wireless mobility, this model will not meet those specific requirements.
The QIDAIZUOEN 100 serves a completely different purpose in the ecosystem of audio gear. It is a bulk solution designed for distribution, inventory management, and situations where hygiene or loss is a major concern. The package contains 100 pairs of in-ear earbuds, each individually wrapped in plastic. This packaging strategy speaks directly to the needs of schools, camps, or large events where handing out clean, new equipment to dozens of people simultaneously is necessary. The inclusion of smaller earbud caps is a thoughtful detail for users with smaller ear canals, ensuring a tighter seal and better retention than standard one-size-fits-all models.
Functionally, these are basic in-ear monitors. They utilize dynamic drivers with a frequency response of 20 Hz to 20,000 Hz, which covers the audible spectrum adequately for their price point. The material is primarily plastic, which aligns with their disposable nature. They are lightweight and unobtrusive, making them suitable for quick tasks like listening practice, online schooling, or background music during parties. The lack of a microphone and any remote controls keeps the design simple and cost-effective.
The trade-offs here are inherent to the "disposable" classification. These earbuds are not built for long-term durability. With a manufacturer warranty of only three months compared to the one-year coverage on the i37, they are clearly positioned as temporary assets. The in-ear style can become uncomfortable for some users over several hours, especially those with sensitive ear canals or those who prefer the open feel of on-ear designs. There is no flexibility in the headband to adjust for fit beyond swapping the silicone tips. This product is ideal for anyone who needs to outfit a large group quickly without worrying about individual care or long-term wearability.
• Best for battery life → Not applicable, as both products are strictly wired with no batteries involved.
• Best for big ears and comfort → ELECDER i37, thanks to its plush on-ear cushions and adjustable band that prevents pinching.
• Best for bulk distribution → QIDAIZUOEN 100, offering 100 individually wrapped units perfect for classrooms or events.
• Best for noise isolation → QIDAIZUOEN 100 (passive seal), though neither has active noise cancellation; the i37 offers sound isolation via cup shape.
• Best for calls and microphones → Neither product includes a microphone; both require external solutions for voice communication.
• Best for portability and storage → ELECDER i37, due to its foldable design which collapses easily into a bag.
• Best for small ear canals → QIDAIZUOEN 100, specifically because it includes smaller earbud caps in the package.
• Best for durability and longevity → ELECDER i37, built with plush materials and a one-year warranty for repeated daily use.
After weighing the specifications and real-world applications of both devices, I recommend the ELECDER i37 for most individual buyers, particularly those looking for best head phones for big ears. The plush on-ear design and adjustable headband provide a level of comfort and security that in-ear buds simply cannot match for extended listening sessions. While the QIDAIZUOEN 100 is a fantastic logistical tool for schools or events, it lacks the build quality and ergonomic considerations needed for a primary personal audio device. If you are purchasing for yourself or a family member who needs reliable, long-lasting audio that doesn't hurt after an hour of use, the i37 is the clear winner. It delivers the necessary extra bass and clarity for immersive experiences without the discomfort often associated with cheaper alternatives.
Yes, the ELECDER i37 is specifically designed with an adjustable headband and plush ear cups that accommodate larger head sizes comfortably, whereas the QIDAIZUOEN 100 relies on in-ear tips that may not suit everyone.
No, neither the ELECDER i37 nor the QIDAIZUOEN 100 includes a built-in microphone or remote controls, so they cannot be used for hands-free calling or voice chat.
Absolutely, the bulk pack of 100 individually wrapped earbuds with included small caps makes it highly practical for teachers managing large groups of students who need disposable or shared audio gear.
Both utilize dynamic drivers with a 20 Hz to 20,000 Hz frequency range, but the i37 likely offers a fuller soundstage due to its on-ear enclosure, while the 100 pack relies on in-ear passive isolation.
