• Bywulanda Upgrade USB Type — biggest strength: a hard 94dB volume ceiling plus a USB-C wired connection that needs no adapter, aimed squarely at protecting young ears during school, tablet time and travel.
• Bywulanda Upgrade USB Type — biggest trade-off: it is wired only, so there is no Bluetooth freedom, and the Type-C jack means older devices with a 3.5mm socket are out of the question.
• HAOMUK Replacement Earpads — biggest strength: a tool-free, seconds-long swap that restores an existing pair of Bose on-ear headphones with thicker foam and protein leather for better noise isolation.
• HAOMUK Replacement Earpads — biggest trade-off: it does not produce a single sound on its own. It only fits specific Bose models, and if your headphones are a different brand, it is useless.
• Who each pick is for: choose Bywulanda if you are buying headphones for a child or student who uses USB-C devices; choose HAOMUK if you already own compatible Bose on-ear headphones and the cushions are worn out.
The Bywulanda Upgrade USB Type is, at its core, a safety-first on-ear headphone for kids and students. The headline spec is the 94dB volume limit, and that number is the whole point. For parents, 94dB is the difference between a child who can listen at a reasonable level and one who can crank a movie soundtrack to ear-ringing volumes on a long car ride. The headphones also list sound isolation as their noise control approach, which means outside noise is dampened passively rather than cancelled electronically — a simpler design with fewer things to break or charge.
On the audio side, Bywulanda uses 40mm dynamic drivers with a 30 ohm impedance and 94dB sensitivity. In plain terms, that combination is easy to drive from a phone or tablet over USB-C without needing a separate amplifier. The connection is wired Type-C with no USB converter required, so it is genuinely plug-and-play on modern smartphones and tablets that have dropped the old headphone jack. If your household has moved to USB-C devices, this removes one small daily annoyance.
Comfort and portability are where this headphone earns its place in a school bag. The headband is adjustable and stretches to fit heads from kids up to teenagers, the earcups are on-ear with a faux leather and plastic build, and the whole thing folds down compactly for travel. Controls are simple: a button-based volume control, no touch gestures to fumble with. It ships in Light Purple with a two-year warranty and a user manual in the box.
Who should buy it? Parents and students who want a wired, durable, volume-limited on-ear headphone for school, tablet use, movies, gaming and travel — especially in USB-C households. Who should skip it? Anyone who wants wireless freedom, anyone with a 3.5mm-only device, and adult listeners who want an unregulated volume ceiling or a more premium audio experience. It is a purpose-built product, not an all-rounder.
The HAOMUK Replacement Earpads are a maintenance part, and they are honest about it. They fit three specific Bose on-ear families: On-Ear 2 (OE2 and OE2i), SoundLink On-Ear, and SoundTrue On-Ear. If your headphones are not on that list, stop here — no amount of clever installation will make them fit. HAOMUK explicitly asks buyers to confirm their headphone model before purchase, and that is the single most important step in the whole process.
Where these pads shine is the swap itself. You pinch the edge of the old cushion, pull it out, take the plastic insert out of the new pad, tuck the rubber lip into the groove around the earcup, work your way around with your fingers, and twist slightly to seat it. No tools, no adhesive, no trip to a repair shop. The whole job takes seconds per side, and the result is a headphone that feels close to new again rather than one headed for a drawer.
Materials matter here too. HAOMUK uses high-quality foam wrapped in protein leather, with the leather and webbing fabric matching the original pads. The brand states the fit is tight after replacement and that the new cushions are slightly thicker than stock, which adds a bit more noise isolation. That extra thickness is a real, practical benefit for anyone who uses their Bose on-ears on commutes, in open offices, or while studying.
Who should buy them? Owners of compatible Bose on-ear headphones whose cushions are flattened, cracked, flaking or simply uncomfortable. Who should skip them? Anyone with a different headphone brand, anyone hoping for a full headset rather than a part, and anyone who wants a warranty-backed purchase — the warranty field for this product is listed as not applicable, unlike the Bywulanda's two-year coverage.
Side-by-Side: Which Should You Choose?
• Best for reviving headphones you already love → HAOMUK Replacement Earpads. It is a repair part, and it does that one job well.
• Best for USB-C devices with no adapter hassle → Bywulanda Upgrade USB Type. Wired Type-C, plug-and-play, no converter needed.
• Best for better noise isolation on existing Bose on-ears → HAOMUK Replacement Earpads. The added thickness over stock pads is a genuine upgrade.
• Best for travel and school bags → Bywulanda Upgrade USB Type. The foldable, compact design and adjustable headband make it easy to pack.
• Best for a tool-free five-minute fix → HAOMUK Replacement Earpads. No tools, no adhesive, no skill required.
• Best for a complete listening setup out of the box → Bywulanda Upgrade USB Type. The HAOMUK pads make no sound on their own.
• Best for long-term value on an existing pair → HAOMUK Replacement Earpads, assuming your headphones are one of the three compatible Bose models.
If I were buying for a child or student in a USB-C household — for school, tablet time, travel, or a work-from-home study setup — I would buy the Bywulanda Upgrade USB Type. In my opinion, the 94dB volume limit, the adapter-free Type-C connection, the foldable on-ear design and the two-year warranty make it the more complete, more protective purchase for that specific buyer. I would only choose the HAOMUK Replacement Earpads if I already owned Bose On-Ear 2, SoundLink On-Ear or SoundTrue On-Ear headphones and just needed to refresh worn cushions. For work from home, that means the Bywulanda for a young listener's own setup, and the HAOMUK only as upkeep on a parent's existing Bose pair.
On-ear designs generally suit smaller ears better than bulky over-ear cups, and the Bywulanda Upgrade USB Type is built around an on-ear, adjustable-headband format that fits kids through teenagers. Its 94dB limit and lightweight foldable build make it a sensible pick for younger listeners. Just confirm your device has a USB-C jack, since that is the only connection it offers.
Yes — this is essential. HAOMUK states the pads fit Bose On-Ear 2 (OE2 and OE2i), SoundLink On-Ear and SoundTrue On-Ear headphones only, and asks buyers to confirm their model before purchase. If your headphones are a different brand or model, these cushions will not fit.
No tools are needed. Pinch the edge of the old cushion and pull it out, remove the plastic insert from the new pad, tuck the rubber lip into the groove around the earcup, then work the rest of the lip into place with your fingers and twist slightly to seat it. HAOMUK says the whole swap takes seconds per side.
They work differently. The Bywulanda Upgrade USB Type lists sound isolation as its noise control method, dampening outside noise passively. The HAOMUK pads add thickness over the original Bose cushions, which HAOMUK states improves noise isolation on the headphones you already own. Neither uses active noise cancellation.
