If you want a wired on-ear pair you can fold away, plug into almost anything and hand to a kid without worrying, choose rockpapa Grade; if you need a newer on-ear headset with a longer warranty and a built-in in-line remote for calls and track skipping, choose ELECDER i45. Both are corded 3.5mm headphones aimed at the same crowd, and for hiking — where you want zero battery anxiety and a cable that survives a backpack — either one gets the job done. The real split comes down to warranty length, controller type and who the headphones were built for.
• rockpapa Grade — biggest strength: a 40mm dynamic driver, 32 ohm impedance and a 4.9ft nylon-woven, no-tangle cord, plus a 1-year hassle-free protection plan and a folding shell.
• rockpapa Grade — biggest trade-off: it's a wired-only design with no Bluetooth despite the spec sheet listing a wireless technology field, so treat it as a corded headphone and nothing more.
• ELECDER i45 — biggest strength: a 40mm dynamic driver with sound isolation, ultra-soft padded cushions, an adjustable size slider and a 24-month worry-free warranty.
• ELECDER i45 — biggest trade-off: the controller is listed as a media control with touch as the control method, which is less predictable on the move than a physical button.
• Who rockpapa Grade is for: listeners age 10+ who want a simple, durable, foldable wired headphone for school, laptops, airplanes and Chromebooks.
• Who ELECDER i45 is for: adults and teens who want a lightweight folding on-ear headset with in-line call and track control and a longer warranty.
The rockpapa Grade is a foldable on-ear wired headphone built around a 40mm dynamic driver, with 32 ohm impedance, 106±3dB sensitivity and a 20Hz–20kHz frequency range. In plain terms: it's easy to drive. You don't need an amp or a special source — a laptop headphone jack, a tablet, an MP3 player, a game console or an airplane seat socket will all push it to a usable volume. The 1.5m (4.9ft) nylon-woven cord is the spec I keep coming back to, because a braided cable that resists tangling is exactly what you want when the headphones get stuffed into a daypack between trails.
The design details tell you who rockpapa had in mind. It's a folding, lightweight build in black with leather and nylon materials, an on-ear circular earpiece, a volume control and button-based operation. The manufacturer lists it for children age 10 and up, which lines up with the "school head phones" framing — this is the pair you buy for a kid who needs something for Chromebook class work, or for an adult who just wants a cheap, tough backup set for the commute. The 1-year hassle-free protection and the stated 12–24 hour customer service response window round out the pitch.
Who should skip it? Anyone who wants wireless freedom, a longer warranty, or a remote that handles calls and track skipping without reaching for the phone. The rockpapa's control is a volume control — useful, but not a full media remote.
The ELECDER i45 is also an on-ear folding wired headphone with a 40mm dynamic driver, and it competes on the same ground: rich bass, crisp midrange and sound isolation that pushes down background noise. Where it differentiates is in the comfort and control story. The ear cushions are described as padded, ultra-soft foam that helps block outside noise, and the headband has an adjustable size slider so the fit isn't one-size-fits-all. If you've ever had a fixed-size on-ear clamp down on your ears after an hour, that adjustability matters more than any spec number.
The controller is the other headline. The i45 uses a media control rather than a plain volume control, which is what you want if you take calls on the move — the in-line mic means you can answer and skip tracks without pulling your phone out. The cord is a 1.5m nylon-braided, tangle-free cable, matching the rockpapa's approach. ELECDER backs it with a 24-month worry-free warranty, double the coverage of the rockpapa, and lists its target user as adult. The blue/black colorway is the only finish named in the data.
Skip the i45 if you specifically want a kids' headphone with a stated age range, or if you prefer physical buttons over a touch-style control method — on a trail, gloves and touch controls don't always get along.
• Best for warranty length → ELECDER i45. 24 months versus 1 year is a real difference on a headphone that's going to live in a bag.
• Best for calls and track control → ELECDER i45. The media control handles dialing and skipping; the rockpapa's control is volume only.
• Best for a stated kid-friendly fit → rockpapa Grade. It's explicitly listed for children age 10+, which the i45 is not.
• Best for a simple, predictable control → rockpapa Grade. Buttons beat touch when you're wearing gloves or moving.
• Best for adjustable comfort → ELECDER i45. The size slider and ultra-soft padded cushions give it the edge for long sessions.
• Best for a fast-charging Bluetooth alternative → neither. Both are wired 3.5mm headphones; if you specifically want a best fast charging bluetooth headset for hiking, you're shopping in the wrong category.
• Best for a voice assistant headset for hiking → ELECDER i45. The in-line mic and media control make it the more practical of the two for triggering your phone's assistant on the move.
• Best for plug-and-play simplicity → either. Both use a standard 3.5mm jack and a 1.5m nylon cord, so laptop, tablet and airplane use is identical.
I'd buy the ELECDER i45. The 24-month warranty, the media control with in-line mic, and the adjustable slider with soft padded cushions make it the more flexible headphone for an adult who wants one pair to do calls, music and travel. For hiking specifically, the i45's in-line control means I can take a call or skip a track without digging my phone out of a pocket. The rockpapa Grade is the better pick if you're buying for a child age 10+ or you just want the simplest possible button-controlled wired headphone with a tough braided cord. Whichever you lean toward, check the current price on Amazon before you commit.
what are the best open ear headphones
Neither of these is an open-ear design — both the rockpapa Grade and the ELECDER i45 are on-ear headphones, meaning the cushions rest against your ears rather than sitting outside them. If you want true open-ear audio, look for a different category entirely. For on-ear listening, both use a 40mm dynamic driver.
are on ear headphones good
Yes, for the right job. On-ear models like these two are lightweight, foldable and easy to carry, and both use sound isolation to cut background noise. The trade-off is that on-ear cushions press against your ears, which is why the i45's adjustable slider and ultra-soft padding matter for longer sessions.
are open ear headphones good
They can be, but that's a different product type from either headphone here. The rockpapa Grade and ELECDER i45 are on-ear closed designs with 3.5mm wired connections, so they block more ambient sound than open-ear models would. If noise isolation is your priority, on-ear is the better fit.
what are the best in-ear headphones
That's a separate category again — neither the rockpapa Grade nor the ELECDER i45 is in-ear. Both are on-ear wired headphones with a 40mm dynamic driver and a 1.5m nylon cord. If you want in-ear, you'll need to shop a different form factor entirely.
