• ELECDER i45 biggest strength: a 40mm dynamic driver plus an inline microphone and media controls, so it can actually handle calls and track skipping from the cable.
• ELECDER i45 biggest trade-off: it's wired only, so you're tethered to a 3.5mm jack device with no Bluetooth freedom.
• ydzqdxzz 2 biggest strength: you get two headphones in one pack, with a lightweight adjustable headband and a compact foldable frame.
• ydzqdxzz 2 biggest trade-off: it's built around a retro cassette-player aesthetic and doesn't list a microphone, so it's a listening pair first, not a calling pair.
• Pick ELECDER i45 if your priority is a single, call-ready wired headphone for school, travel, tablets and phones.
• Pick ydzqdxzz 2 if you want a pair to share, a spare to stash in a bag, or a nostalgic look to pair with older portable audio gear.
The i45 is the more "modern utility" of these two. It runs a 40mm dynamic driver, which is the same driver size class as the ydzqdxzz 2, and ELECDER pairs it with a sound-isolation design meant to cut down background noise. For a wired on-ear headphone, that combination is the sensible baseline: enough driver surface for real bass and a clear midrange, plus passive isolation so you're not fighting the room around you.
What separates it is the cable. The i45 has an inline microphone with media controls, so you can take a call and skip tracks without touching your phone. That's the single most important spec here if you're shopping for headphones for calls, or if you've been looking for sleep headphones for calls that don't need charging overnight. The cord itself is nylon-braided, which is the anti-tangle, anti-fray choice — a small detail that matters a lot if the headphones live loose in a backpack.
Comfort and portability are handled the way you'd expect from a portable on ear headphone: padded ear cushions, padded headband, an adjustable size slider, and a foldable frame. ELECDER also states the design protects ears up to 85 dB, which is the kind of detail parents notice when buying for kids and teens. It's wired, 3.5mm, and works with any phone, tablet or laptop that still has that jack. The listed color is blue, with a blue/black style, and it ships with a user guide and a 24-month warranty.
Who should buy it: anyone who wants one reliable wired headphone that does music and calls, students on tablets and Chromebooks, travelers on planes, and parents buying for teens who don't need another battery to charge. Who should skip it: if you want wireless freedom, or you specifically want a pair to hand out to two people at once, this isn't that product. The i45 is one headphone for one listener.
The ydzqdxzz 2 is a different proposition entirely, and the name gives it away: it's a two-pack. You get two wired on-ear headphones in the box, in a classic retro orange, aimed squarely at cassette players and portable audio devices. The styling is the point here — round earcups, vintage vibe, foam-and-synthetic-leather padding over a plastic and metal frame. If you like that look, nothing else in this comparison scratches that itch.
On the spec side it's a genuine headphone, not a novelty. The 40mm dynamic driver matches the i45, impedance is listed at 32 ohm (easy to drive from a phone or portable player), sensitivity at 105 dB, and frequency response at 20. It's a 3.5mm wired connection with no battery and no charging, which is exactly what makes it a good fit for older gear — cassette players, retro handhelds, anything with a headphone jack that you don't want to fuss over.
The practical wins are the lightweight build, the adjustable headband, and the compact foldable design. Two pairs means you can share with a friend, keep one at home and one in a bag, or hold a backup for the day one gets lost. That's a real advantage for families and for anyone who has ever watched a single pair of headphones vanish into a school bag.
Who should buy it: retro-audio fans, cassette-player owners, anyone who wants two cheap-feeling-but-functional wired pairs for sharing or backup, and shoppers who care more about look and portability than about call features. Who should skip it: if you need a microphone for calls. The ydzqdxzz 2 lists inline controls with push-button operation, but no microphone is specified in the data, so I wouldn't buy it as a calling headset. Its warranty is also listed at just 1, versus ELECDER's 24 months.
• Best for calls → ELECDER i45. It's the only one of the two with a listed inline microphone and media controls.
• Best for sharing or backup → ydzqdxzz 2. Two headphones per pack, no debate needed.
• Best for retro style and cassette players → ydzqdxzz 2. The orange vintage design and round earcups are built for that aesthetic.
• Best for kids, teens and school use → ELECDER i45. Padded cushions, an 85 dB ear-protection note, a tangle-free braided cord and a longer warranty all point that way.
• Best for travel and packing → a tie, with a nudge to ydzqdxzz 2. Both fold, but two foldable pairs in one purchase is a lot of portability per box. The i45 still wins on cable durability.
• Best for headphones that just work with a phone or tablet → ELECDER i45. 3.5mm wired, inline controls, no setup, no charging.
• Best for low-fuss listening without batteries → both. Neither needs charging; both are wired 3.5mm.
• Best all-rounder if you only buy one → ELECDER i45. It does more jobs in one product.
If I were buying one pair of portable on ear headphones today, I'd take the ELECDER i45. The driver size matches its rival, but the microphone, inline media controls, braided cable and 24-month warranty make it the more useful object day to day — especially for calls, which is where the ydzqdxzz 2 is weakest on paper. In my opinion, the ydzqdxzz 2 is the better buy only in one scenario: you specifically want the retro look, or you want two pairs to share. Otherwise the i45 is the safer pick for school, travel and everyday wired listening.
what are the best open ear headphones
"Open ear" usually means a design that doesn't seal over or inside the ear canal, and neither of these two is that — both are on-ear headphones with sound isolation, not open-ear models. If you want an on-ear pair for calls, the ELECDER i45 is my pick here because it lists a microphone; the ydzqdxzz 2 doesn't. If open-ear is a hard requirement, neither of these fits and you should look at a dedicated open-ear design instead.
are on ear headphones good
Yes, on-ear headphones are a solid choice for portability and everyday listening — both of these are lightweight, foldable and wired via 3.5mm, so there's no battery to manage. The trade-off is that on-ear cushions rest against the ear rather than around it, so isolation is moderate rather than total. For commuting, studying and casual music, that's a reasonable compromise.
are open ear headphones good
Open-ear headphones are good if you want to stay aware of your surroundings, but that's the opposite of what these two do — the ELECDER i45 and ydzqdxzz 2 both use sound isolation to reduce background noise. If you need to hear traffic or a conversation while listening, an open-ear model is the right category. If you want to block out a noisy room, isolation like these two offer is the better fit.
what are the best in-ear headphones
That's a different category from both products here. The ELECDER i45 and ydzqdxzz 2 are on-ear headphones with 40mm dynamic drivers and 3.5mm wired connections, not in-ear models. If you want in-ear, shop specifically for that form factor; if you want a lightweight wired on-ear pair for music and calls, the i45 is the one I'd recommend.
One practical note before you decide: pricing on both of these moves around, so check the current price on Amazon using the button on this page rather than trusting any figure you see elsewhere.
