If you want simple, foldable wired headphones for work at a shared computer, choose ELECDER i37; if you need wireless open-ear listening for work while staying aware of your surroundings, choose Micool Open Ear Headphones. For an office day built around a laptop or tablet, the Micool’s Bluetooth connection and open design make it the more flexible everyday option, while the i37 is the straightforward pick when a 3.5 mm jack and a cord suit your setup.
ELECDER i37 vs Micool Open Ear Headphones at a Glance
• Micool Open Ear Headphones’ biggest strength: wireless, clip-on open-ear listening with up to 8 hours of use per earbud and 36 hours total with the case; its trade-off is that Bluetooth and charging are part of the routine.
• Choose the i37 for a child or teen who needs a simple connection to a Chromebook, tablet, laptop, or other device with a headphone jack.
• Choose Micool for an adult who wants open-ear wireless headphones for work, calls, commutes, or workouts.
• Neither design fully covers the ears: the i37 sits on them, while Micool leaves them open. The fit and listening style are different enough that neither is a universal substitute for the other.
The ELECDER i37 is a wired, on-ear headphone designed with children and teens in mind. Its foldable headband makes it easier to pack in a school bag or travel bag, and the adjustable fit and cushioned ear pads are intended for everyday listening. The 4.9-foot cord gives a child some room to move while connected to a nearby device, whether that means doing schoolwork at a desk or listening during a car ride.
Its 3.5 mm plug is the key practical detail. The i37 can connect directly to a compatible Chromebook, laptop, tablet, or smartphone without Bluetooth pairing or charging. That can make it a simple choice for school devices that have a headphone jack. The on-ear design is described as reducing ambient noise while still allowing some awareness of the surroundings, a useful balance for a child who needs to hear nearby activity. The listed lead-free and BPA-free materials may also matter to parents choosing headphones for a younger listener.

Who should skip it: Skip the i37 if you need Bluetooth, a wireless case, or an adult open-ear fit for hands-free work calls.
Micool’s open-ear clip-on design is aimed at adults who want to listen without sealing the ear canal. Soft silicone memory ear hooks hold the earbuds in place, while the open structure is intended to keep the wearer aware of surrounding sounds. That makes this design a plausible fit for workdays that include walking between rooms, commuting, or listening while remaining attentive to nearby people. It is also described for running and gym use, with a sweatproof and breathable design.
For office use, Bluetooth 6.0 connects the headphones wirelessly to a smartphone or laptop. Dual microphones with noise reduction are intended for hands-free calls, and the listed low-latency audio feature is relevant to video and games. Opening the case triggers auto-reconnection, so returning to listening does not require plugging in a cord. Touch controls handle playback, calls, and volume adjustments.
Battery life is a meaningful part of the choice: the listed figure is up to 8 hours of music per earbud, with 36 hours total using the charging case. The case uses USB-C fast charging. Those details suit someone who wants to get through a long day with the option to recharge between listening sessions, but they also mean keeping track of a case and charging it. Micool is wireless and adult-oriented; it does not have a headphone jack.
Who should skip it: Skip Micool if your device needs a wired 3.5 mm connection, or if you specifically want headphones that cover the ears to reduce surrounding sound.

My Verdict
For work, I would choose Micool Open Ear Headphones if I wanted wireless calls, an open-ear fit, and the flexibility to move around without a cable. The Bluetooth connection, dual microphones, and up-to-8-hour per-earbud listening figure make it the more work-oriented choice of these two. I would choose the ELECDER i37 instead for a child or teen using a compatible school device, where a foldable wired design is the more straightforward match.
Think first about the device you will connect. The i37 needs a 3.5 mm headphone jack; Micool uses Bluetooth and has no headphone jack. If your work laptop or phone does not have a compatible jack, the i37 may not fit your setup as supplied. If you want to avoid wireless pairing, the reverse is true: the i37 keeps the connection simple and direct.
Next, consider how much awareness of your surroundings you want. The i37’s on-ear cushions are described as reducing ambient noise while allowing awareness, whereas Micool’s open-ear structure leaves the ear uncovered. Neither is described as a fully isolating, over-ear design. For people who need to hear nearby colleagues or sounds while listening, Micool’s open design is the clearer fit; for a child who needs some reduction of classroom chatter while retaining awareness, the i37 is designed with that balance in mind.
Fit and audience matter, too. ELECDER presents the i37 for kids and teens, with an adjustable headband and cushioned on-ear pads. Micool is described for adults and uses silicone ear hooks to clip onto the ears. If you are searching for “comfortable sleep headphones for work,” these two products are not specifically described as sleep headphones; the i37 is an on-ear school model, and Micool is a clip-on open-ear design. For “earbuds for work,” Micool is closer to that use case because it is wireless and includes call-focused features, though it is open-ear rather than an in-ear design.
Finally, factor in charging and support. Micool provides a charging case and USB-C fast charging, but its wireless use depends on keeping the earbuds and case charged. The i37 requires no battery charging, but its cable can limit movement and needs a compatible jack. ELECDER lists a one-year warranty and 24/7 email support; Micool lists a six-month warranty. If current price matters to your decision, check the current price on Amazon rather than assuming either model is the better value from its features alone.
