If you want to restore a pair of aging Bose on-ear headphones with better bass and stronger noise isolation, choose SOULWIT Earpads; if you need thirty wired on-ear headphones ready for a classroom, testing lab or library cart, choose Gaosen Bulk Class Set.
• SOULWIT Earpads — biggest strength: high-density foam paired with soft protein leather, which the manufacturer says improves bass and noise isolation while keeping the original sound signature intact. Biggest trade-off: it is a replacement part, not a product — it only fits specific Bose on-ear models and does nothing for any other headphone.
• Gaosen Bulk Class Set — biggest strength: thirty complete wired on-ear headphones in one set, with adjustable headbands, flexible plastic brackets and 40 mm dynamic drivers. Biggest trade-off: it is built for shared, supervised use, not for critical listening — no noise control, a fixed 4-foot cord and plastic construction.
• Who SOULWIT Earpads is for: someone who already owns Bose OE2, OE2i, SoundTrue On-Ear or SoundLink On-Ear headphones and wants them to feel and sound new again.
• Who Gaosen Bulk Class Set is for: teachers, tutors, school IT staff and program organizers who need a stack of cheap, durable on-ear headphones that students can pass around.
The SOULWIT Earpads exist for one job: replacing worn-out cushions on a specific family of Bose on-ear headphones. The compatibility list is narrow and clearly stated — OE2, OE2i, SoundTrue On-Ear and SoundLink On-Ear. The listing also warns that these do not fit the Bose On Ear Generation 1, so check your model number before you order. That narrowness is a feature, not a flaw. A pad cut for one shell shape seats properly, seals properly, and does not shift around while you wear it.
The materials are where the real upgrade lives. SOULWIT uses high-density foam wrapped in soft protein leather. In practice, that combination is what gives you a tighter seal against the ear, which is exactly what a collapsing, flaking stock pad can no longer do. The manufacturer's claim is that this restores bass response and improves noise isolation — and that logic holds up, because a pad that seals is a pad that keeps low frequencies in and outside noise out. The company also states that the pads are modeled precisely so they will not alter the sound performance of your headphones, and that they'll make the headphones look new again. For a $100-plus pair of headphones with disintegrating cushions, that is the whole point.
Installation is meant to be quick. SOULWIT includes a user guide and estimates roughly five minutes for the swap. That is realistic for a press-fit or peel-and-stick style replacement — the guidance matters more than the tooling, and having written steps in the box removes most of the guesswork. Two practical notes worth flagging: the pads ship in black leather only, and the warranty description is listed as "No," so there is no stated coverage to lean on. This is a straightforward consumable part, priced accordingly.
Gaosen Bulk Class Set: Who It's For
The Gaosen Bulk Class Set is a completely different animal: thirty complete on-ear headphones, model GS857, in mixed bright colors. The pitch is institutional, and the spec sheet backs that up. You get soft foam ear cushions, a lightweight frame and an adjustable headband designed to fit a wide range of head shapes — the manufacturer specifically calls out long-term comfort so kids can wear them through a class period without fidgeting. The cups swivel, which helps them sit flat and pack down neatly.
Durability is the other half of the story. The bracket is flexible plastic that the maker says can be bent at a large angle without snapping, and the cord is thickened to survive repeated handling by students. That matters enormously in a shared setting, where headphones get yanked, dropped and stuffed into bins. Thirty pairs that survive a school year beat five pairs that sound great and break in a month.
On audio, Gaosen lists 40 mm dynamic drivers, a 32-ohm impedance, 115 dB sensitivity and a frequency range of 20 Hz to 20 kHz. Those numbers describe an easy-to-drive headphone — 32 ohms and high sensitivity mean almost any phone, tablet or laptop can push it to a usable volume without a headphone amp. The 20 Hz–20 kHz range is the standard full-bandwidth claim, and the maker describes the tuning as balanced and clear, aimed at spoken-word content, studying and video. There is no noise cancellation or noise control of any kind, so these are not for a noisy bus or a loud cafeteria.
Connectivity is a fixed 4-foot 3.5 mm wired jack, listed as compatible with Chromebooks, iPads, laptops, PCs, Android tablets, MP3 players and fitness equipment. A 4-foot cord is a sensible length for a desk or a testing station — long enough to reach, short enough not to tangle into a mess. Gaosen backs the set with a one-year warranty and says support replies within 12 hours. Realistically, the most common frustration with any classroom headphone is a failed cable or a snapped band, so having a stated warranty on a thirty-pack is genuinely useful.
Side-by-Side: Which Should You Choose?
• Best for restoring sound quality on existing Bose headphones → SOULWIT Earpads. The high-density foam and protein leather seal is the mechanism that brings back bass and isolation.
• Best for outfitting a whole room at once → Gaosen Bulk Class Set. Thirty complete headphones in one purchase, in mixed colors.
• Best for noise isolation → SOULWIT Earpads. Gaosen lists noise control as "None"; SOULWIT's design is explicitly built around a tighter seal.
• Best for durability under rough handling → Gaosen Bulk Class Set. Flexible plastic brackets, thickened cord, and a frame designed to be bent without breaking.
• Best for kids and students → Gaosen Bulk Class Set. Adjustable headband, lightweight build, swivel cups and bright colors aimed squarely at younger users.
• Best for adults who already own quality headphones → SOULWIT Earpads. You are upgrading a headphone you like rather than buying a new one.
• Best for spoken-word, testing and study audio → Gaosen Bulk Class Set. 32-ohm impedance and 115 dB sensitivity make them easy to drive from a Chromebook or tablet.
• Best for guaranteed coverage → Gaosen Bulk Class Set. A one-year warranty is stated; SOULWIT lists no warranty.
If your Bose on-ear headphones still work but feel flat, loose or scratchy, I would buy the SOULWIT Earpads. In my opinion, a well-sealed foam-and-protein-leather pad is the single highest-impact fix for that specific problem, and the five-minute install and included guide make it a low-risk one. If you are stocking a classroom, lab or library, I would buy the Gaosen Bulk Class Set instead — thirty wired on-ear headphones with a flexible frame, a one-year warranty and a 4-foot cord is the sensible unit of purchase for shared student use. Two different jobs, two different answers. Neither one substitutes for the other.
how to wear over the ear headphones
On-ear models like these sit on the ear rather than around it, so the cushion rests against the outer ear. Slide the adjustable headband until the pads press gently but evenly against both ears — the Gaosen set's adjustable band and swivel cups are designed for exactly that fit. Too loose and you lose bass and isolation; too tight and it becomes uncomfortable after a while.
how to clean on ear headphones
Wipe the ear cushions with a soft, slightly damp cloth, and avoid soaking the foam or the leather. On the SOULWIT pads, the protein leather surface cleans easily with a light wipe; on the Gaosen foam cushions, keep moisture to a minimum so the foam doesn't degrade. Unplug the 3.5 mm jack first, and never submerge any part of the headphone.
how to clean over the ear headphones
If your headphones have replaceable pads, the deepest clean is often a swap rather than a scrub — which is precisely the case SOULWIT Earpads are designed for. Once a pad is cracked, flaking or permanently flattened, wiping it won't bring back the seal or the bass. For everything else, a dry microfiber cloth on the headband and a barely damp one on the cups is enough.
The spec sheet lists 40 mm dynamic drivers, 32-ohm impedance, 115 dB sensitivity and a 20 Hz–20 kHz range, and the maker describes balanced, clear sound. That is a workable, easy-to-drive headphone for study, video and casual listening. What it is not built for is isolation — noise control is listed as "None" — so a loud room will bleed through.
