If you want a simple, durable, wired pair built specifically for kids and school use, choose ELECDER i37; if you need wireless freedom, long battery life and a mic for calls, choose GREAT SAGE Headphones Over Ear.
These two headphones get compared a lot because they look similar in photos — both fold, both sit on the ear, both come in bright colors. But they are built for completely different people. One is a school-age, cable-tethered workhorse. The other is a wireless all-rounder for teens and adults. Here is how I'd split them.
• ELECDER i37 — biggest strength: Purpose-built for kids and school, with a foldable adjustable headband, a 4.9 ft tangle-free cord, and a low 160 g weight that suits small heads.
• ELECDER i37 — biggest trade-off: It's wired only. There is no Bluetooth and no microphone, so it's tethered to whatever device it's plugged into.
• GREAT SAGE Headphones Over Ear — biggest strength: Bluetooth 5 wireless with up to 20 hours of playtime, a built-in mic, FM radio and a TF card slot for music without any paired device.
• GREAT SAGE Headphones Over Ear — biggest trade-off: Heavier at 0.3 kg with a bigger over-ear cup, and a shorter 6-month warranty versus ELECDER's 1 year.
• Choose ELECDER i37 if you're buying for a young child, a classroom or a school bag.
• Choose GREAT SAGE if you want one wireless pair for commuting, work calls, travel and general listening.
The ELECDER i37 is not trying to be a do-everything headphone. It's trying to be the pair that survives a school year. The design brief is obvious from the spec sheet: foldable and adjustable headband, cushioned on-ear pads, and a 4.9 ft tangle-free cord with an L-shaped 3.5 mm plug. That cord length matters more than people think — it's long enough for a kid to shift around in a car seat or hand a tablet to a sibling without yanking the plug out of the jack.
The safety angle is where it earns its place. The materials are lead-free and BPA-free, and the on-ear cushion design reduces surrounding noise without blocking it out completely. For a child walking through a hallway, a parking lot or an airport, that partial awareness of what's going on around them is genuinely the right call. Full isolation is a feature for adults on a plane; it's a liability for a nine-year-old.
Sound-wise, the numbers are modest and honest: 32 ohm impedance, 93 dB sensitivity, dynamic drivers. That 32 ohm figure is the useful one — low impedance means easy to drive, so a Chromebook, a tablet, a Kindle or a cheap MP3 player can push it to a decent volume without a headphone amp. It will not deliver audiophile bass, and it isn't meant to.
Who should skip it: anyone who wants wireless. There's no Bluetooth here, no microphone, so no Zoom calls and no phone conversations. It also won't satisfy someone chasing deep bass or a wide soundstage — it's a practical kids' headphone, not a listening headphone. And if you're an adult with a large head, the on-ear fit will likely feel tight over long stretches.
GREAT SAGE Headphones Over Ear: Who It's For
The GREAT SAGE is the opposite philosophy: throw everything in. Bluetooth 5 with a 10 m (about 33 ft) range, a 20-hour battery that charges in 3 hours, 360 hours of standby, a built-in microphone, FM radio, TF card playback, six EQ modes, and a 3.5 mm cable included so it keeps working after the battery dies. That last detail is the one I appreciate most — a wireless headphone that becomes a wired headphone when it runs flat is a genuinely useful bit of redundancy, especially on a long trip.
The audio hardware is a step up on paper: oversized 40 mm dynamic drivers with a 20 Hz – 20 kHz frequency range, which is the full span of human hearing. The six EQ modes — bass, jazz, rock, pop, classic — let you nudge the sound toward whatever you're listening to, and for casual listeners that's more useful than a flat, purist tuning. Note the sensitivity figure of 70 dB, which is notably lower than the ELECDER's 93 dB. In practice that means this pair leans on its own amplification (which the battery provides) rather than on your phone's output.
Comfort is where the trade-offs show up. It's an over-ear design with leather-and-plastic construction, a big cushioned earcup and an adjustable headband, so it spreads pressure around the ear rather than pressing on it. But at 0.3 kg it's roughly double the ELECDER's weight, and GREAT SAGE itself recommends taking it off every 1–2 hours so your ears can breathe. That's an honest note, not a flaw — it's just what a wireless over-ear with a battery inside weighs.
Who should buy it: teens and adults who want one pair for music, podcasts, calls and travel; anyone who hates cables; people who want music on a plane or train without draining their phone; and gift buyers who need something that fits "all ages" rather than specifically kids.
Who should skip it: very young children. The wireless mode, the touch and voice controls, the FM and TF functions — that's a lot of complexity for a small kid, and a 6-month warranty is a shorter safety net than ELECDER's 1 year. If you're buying for a five-year-old, the wired i37 is the more sensible purchase.
• Best for young kids and school → ELECDER i37. Kid-and-teen age range, foldable, lightweight, tangle-free 4.9 ft cord.
• Best for battery life and wireless freedom → GREAT SAGE. Up to 20 hours of playback, 360 hours standby, 3-hour charge, Bluetooth 5 with a 10 m range.
• Best for calls and meetings → GREAT SAGE. Built-in microphone and voice control; the ELECDER has no mic at all.
• Best for long listening sessions → ELECDER i37. At 160 g versus roughly 300 g, the lighter pair wins on a two-hour homework or gaming stretch.
• Best for travel with a child → ELECDER i37. It folds flat into a school bag or suitcase and plugs into a seat-back screen or tablet with no pairing step.
• Best for travel as an adult → GREAT SAGE. Foldable, wireless, with FM radio and TF card playback so you can listen with no phone at all.
• Best for durability coverage → ELECDER i37. A 1-year warranty and 24/7 email support beat a 6-month warranty in my book.
• Best for sound flexibility → GREAT SAGE. Six EQ modes and 40 mm drivers across a 20 Hz – 20 kHz range, versus a single fixed tuning on the ELECDER.
• Best for a device you never want to charge → ELECDER i37. Pure wired, plug and play, nothing to remember.
I'd buy the ELECDER i37 if the person using it is a child, a student, or anyone who mainly listens on a Chromebook, tablet or PC and doesn't want to think about charging. It's light, it's built around kid-safe materials, the cord is the right length, and the warranty is twice as long. In my opinion it's the more honest product for that specific job.
I'd buy the GREAT SAGE Headphones Over Ear for myself or any teen or adult who wants one pair to cover music, calls and travel. The 20-hour battery, mic, FM radio and wired fallback make it the far more versatile of the two — you just pay for that with weight, a shorter warranty and more complexity. If versatility is the priority, this is the one.
No. It's a wired on-ear headphone with a 3.5 mm jack and a 4.9 ft cord. There's no Bluetooth and no battery, so it works instantly with anything that has a headphone port — Chromebooks, tablets, laptops, phones, Kindles and DVD players.
Yes. It has a built-in mic for calls and voice control, which the ELECDER i37 doesn't offer. It also supports FM radio and TF card playback, so you can listen without connecting it to a phone at all.
For a young child, the ELECDER i37. It's roughly half the weight, designed for a kid-and-teen age range, made with lead-free and BPA-free materials, and its on-ear cushions reduce noise while still letting your child hear what's happening around them — which matters near roads and in crowds.
They solve different problems, so I wouldn't frame one as strictly better. If you want wireless playback, calls, EQ modes and a 20-hour battery, the GREAT SAGE is the only one of the two that does those things. If you want a light, simple, corded pair for school and don't care about Bluetooth, the ELECDER does that job better and carries a longer warranty. Check the current price on Amazon for both and match it to how the headphones will actually be used.
