How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a replacement cable that brings a pair of Bose headphones back to life, choose Aquelo Replacement QC35; if you need a lightweight, retro-styled pair of portable on-ear headphones you can actually listen through, choose ydzqdxzz 2. These two listings share a "portable on ear" label but solve completely different problems, and mixing them up is the single most common mistake buyers make here.
• Aquelo Replacement QC35 — biggest strength: an angled 3.5 mm to 2.5 mm male-to-male AUX cable, 4.6 ft long, built as a direct replacement for damaged or lost cords on a long list of Bose models.
• Aquelo Replacement QC35 — biggest trade-off: it is a cable, not a headphone. Nothing in the box plays audio on its own, and you need a compatible Bose headset to use it.
• ydzqdxzz 2 — biggest strength: two complete wired on-ear headphones in one pack, with a retro orange finish, a foldable frame and an adjustable headband.
• ydzqdxzz 2 — biggest trade-off: it is wired only, with no battery, no charging and no active noise cancellation — just sound isolation and push-button inline controls.
• Who each pick is for: Aquelo Replacement QC35 is for someone who already owns Bose QC35 / QC35 II / QC45 / QC25 / OE2 / SoundLink / SoundTrue / NC700 headphones and needs a fresh cable. ydzqdxzz 2 is for someone who wants an inexpensive, casual, retro-looking pair of headphones — or two of them — to plug into a cassette player, laptop or portable player.
Aquelo Replacement QC35 is a fix, not a purchase you make for fun. Its whole reason to exist is the 2.5 mm socket on the side of a lot of Bose headphones — a narrower jack than the 3.5 mm plug on most phones and laptops. This cable bridges that gap with a 2.5 mm stereo male end for the headphone and an angled 3.5 mm stereo male end for the source. The angle matters more than people expect: a straight plug sticking out of a laptop or a pocket-sized player catches on things, and an angled one lies flatter and snags less.
Compatibility is where this cable earns its keep. The listing names Bose QuietComfort 35 (Series I), QC35 II, QC45, QC25, the OE2 / OE2i / SoundTrue line, SoundLink around-ear wireless, and the Noise Cancelling Headphones 700. It also mentions Apple, Android and Microsoft devices on the other end, which simply means the 3.5 mm side is the standard jack those devices use. Length is 4.6 ft (140 cm), which is a practical middle ground — long enough to reach from a headphone on your head to a laptop on a desk or a player in a bag, short enough that it doesn't turn into a coil of spaghetti.
The honest trade-off: if you don't own a compatible Bose headphone, this does nothing for you. It's also a single cable with no inline remote or microphone mentioned in the specs, so don't buy it expecting call controls. In my opinion, this is the right pick if your Bose cable has frayed, gone missing, or developed a crackle, and you'd rather replace a cord than replace the headphones. If your headphones themselves are dead, skip it.
ydzqdxzz 2 is a different animal entirely. This is a two-pack of complete wired on-ear headphones in a retro orange finish, and the listing leans hard into that vintage identity — cassette players, portable audio devices, that whole aesthetic. The earcups sit on your ears rather than around them, the earpiece shape is round, and the 40 mm dynamic drivers are the kind of size that gives you a full-bodied, casual listening experience rather than a clinical one. Impedance is 32 ohm, sensitivity is 105 dB, and the frequency response figure listed is 20 — all of which points to a set that's easy to drive from a phone, a laptop or a portable player without needing an amp.
The real selling point is convenience and cost-per-pair. Because you get two, you can leave one at a desk and one in a bag, or hand one to a friend or a kid. The headband adjusts, the frame folds, and the whole thing is built from plastic, foam, metal and synthetic leather — lightweight materials chosen for portability rather than tank-like durability. There's an inline control with push buttons, and the noise control is sound isolation, which is the passive kind: the cups block some outside noise simply by covering your ears. There's no active noise cancellation, no battery and no charging, so it never runs out of power — but it also never works wirelessly.
Who should buy it: someone who wants a cheap, cheerful, retro-looking pair for casual listening, cassette deck nostalgia, or a spare set for a teen or a guest. Who should skip it: anyone who needs Bluetooth, active noise cancelling, or studio-grade build quality. The 0.59 g item weight figure in the listing is clearly a data-entry quirk rather than a real weight, so don't read anything into it — judge the portability from the foldable design instead.
• Best for repairing existing Bose headphones → Aquelo Replacement QC35. It's the only one of the two that connects to a Bose headset at all.
• Best for getting a working pair of headphones in the box → ydzqdxzz 2. The Aquelo item is a cable only and explicitly does not include earphones.
• Best for two listeners or a backup pair → ydzqdxzz 2. It ships as two headphones with a cable.
• Best for travel and folding storage → ydzqdxzz 2. The compact, foldable frame is designed to be tossed in a bag.
• Best for reaching across a desk or a couch → Aquelo Replacement QC35. At 4.6 ft, the cable gives you real slack between your head and your device.
• Best for retro style and cassette-player setups → ydzqdxzz 2. The orange vintage look is the entire point of the design.
• Best for a teen-to-adult casual listener → ydzqdxzz 2. The listed age range is teen to adult, with a one-year warranty description.
• Best if you already own Bose and just need a cord → Aquelo Replacement QC35. Buying a whole second headphone to fix a cable problem is money wasted.
If I had to pick one for myself, I'd buy the Aquelo Replacement QC35 — but only because the scenario I care about is keeping a good pair of Bose headphones alive instead of replacing them over a frayed cord. That's the entire value of this cable, and at 4.6 ft with an angled plug, it's a sensible everyday length.
If you don't already own a compatible Bose headphone, my recommendation flips completely: buy the ydzqdxzz 2. It's the only one of the two that gives you something to actually listen through, you get two of them, and the foldable retro design is genuinely handy for portable use. Check the current price on Amazon before you decide, since both are budget-friendly categories where a small difference can tip the scales.
what are the best open ear headphones
Neither of these is an open-ear design. The Aquelo Replacement QC35 is a replacement cable, not a headphone, and the ydzqdxzz 2 is a closed on-ear headphone with sound isolation. If you specifically want open-ear headphones, you'll need to look at a different category entirely.
are on ear headphones good
On-ear headphones like the ydzqdxzz 2 can be very good for casual listening. They're lightweight, they fold up for travel, and the on-ear fit with sound isolation blocks some background noise passively. The trade-off is that on-ear cups rest against your ears rather than surrounding them, which some people find less comfortable over very long sessions than over-ear models.
are open ear headphones good
Open-ear headphones let in ambient sound, which is useful for awareness when you're walking or cycling, but they leak audio and offer little isolation. The ydzqdxzz 2 takes the opposite approach — it's an on-ear closed design with sound isolation, so it's better for focused listening and worse for staying aware of your surroundings.
what are the best in-ear headphones
In-ear headphones sit inside the ear canal and are the most compact option, but neither product here is in-ear. The Aquelo Replacement QC35 is a cable, and the ydzqdxzz 2 is an on-ear model with round earcups and 40 mm drivers. If in-ear is what you want, keep looking — but if you want something light and portable that doesn't go inside your ear, the ydzqdxzz 2 fits that brief.
