How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a low-cost way to keep a pair of portable wired headphones comfortable and hygienic for long office shifts, choose YDYBZB KPH7; if you need to protect and carry a set of kids' wireless headphones — plus their cables and small accessories — choose Lebakort Hard Case Compatible.
• YDYBZB KPH7, biggest strength: five pairs of soft, breathable foam cushions that fit the Koss KPH7 portable wired headphone, so you can refresh worn pads instead of living with flattened ones. Best for office use.
• YDYBZB KPH7, biggest trade-off: it is a consumable accessory, not a headphone and not a case. It only matters if you already own that specific Koss model.
• Lebakort Hard Case Compatible, biggest strength: a hard EVA shell with nylon and a goose-down lining, built to fend off dust, knocks and light moisture while holding iClever HS19 / BTH12 / BTH26 kids headphones in place.
• Lebakort Hard Case Compatible, biggest trade-off: it is storage only — the headphones and accessories shown are not included, and it will not fit a Koss KPH7.
• Who each pick is for: YDYBZB KPH7 for the Koss KPH7 owner who wants fresh, comfortable ear pads; Lebakort for the parent who wants kids' wireless headphones to survive the school bag.
This is a small, unglamorous product that solves a very specific annoyance: foam ear pads that go flat, get grimy, or stop sitting comfortably after months of daily wear. The YDYBZB KPH7 is a set of replacement foam cushions made for the Koss KPH7 portable wired headphone. Each cushion measures roughly 2.16 x 2.16 x 0.39 inches and is made of black foam. You get five pairs — ten pieces in total — in one package. The whole package weighs about 4.54 grams, so this is genuinely tiny stuff, the kind of thing that disappears into a desk drawer until you need it.
The feature that actually matters day to day is the foam itself. It is described as soft and breathable, conforming to the shape of your ear rather than pressing hard against it, which reduces pressure over long listening sessions and cuts down on the stuffy feeling you get from dense, non-breathing pads. That combination — light pressure plus airflow — is exactly what makes a headphone wearable through a full workday rather than for twenty minutes. If you wear the KPH7 for calls, background music, or focus blocks at a desk, tired or compressed pads are the main reason it starts to feel worse over time. Swapping the foam is the cheapest way to reset that.
Who should skip it: anyone who does not own the Koss KPH7. This is not a universal pad, not a headphone, and not a carrying solution. It also will not help if your problem is broken drivers or a damaged cable — foam only fixes foam problems. And if you want something to protect headphones in transit, this is the wrong product entirely; that is what the other half of this comparison is for.
Lebakort Hard Case Compatible: Who It's For
The Lebakort Hard Case is a purpose-built storage shell for iClever HS19, BTH12 and BTH26 kids headphones. The interior compartment is shaped specifically for that family of headphones, so they sit snugly instead of sliding around — the point being to prevent shifting and the scratches that come with being tossed into a backpack. On the opposite side there is a double-layer mesh pocket for cables and small peripherals, with a design intended to keep those bits from falling out. Everything stays in one place, which is the whole job.
The protection story comes from the material stack: nylon for durability on the outside, hard EVA for impact resistance, and a goose-down lining for gentle cushioning against the headphones themselves. In plain terms, that layering is meant to handle dust, everyday collisions and accidental drops. Lebakort also describes the case as semi-waterproof, dustproof and shockproof, which covers the realistic hazards of a kid's commute — rain, crumbs, and the inevitable drop off a chair. The black-and-red colourway makes it easy to spot inside a bag, and the hard shell keeps its shape so it does not crush down onto the contents.
Practicality is clearly the design priority. There is a sturdy exterior hand strap for carrying, and a smooth zipper that opens and closes quickly so a child can get to their headphones without a fight. It is light enough to drop into a larger bag without adding meaningful weight.
Who should buy it: parents of kids using iClever HS19, BTH12 or BTH26 headphones who are tired of tangled cables, scratched plastic and lost dongles. It is a sensible fit for school runs, car trips and holidays.
Side-by-Side: Which Should You Choose?
• Best for long office listening → YDYBZB KPH7. Breathable foam that reduces pressure is the difference between comfortable all day and uncomfortable by lunchtime.
• Best for keeping headphones clean and hygienic → YDYBZB KPH7. Ten pieces means you can replace pads periodically instead of tolerating grubby ones.
• Best for protecting kids' wireless headphones → Lebakort Hard Case Compatible. Hard EVA plus nylon plus goose-down lining is built for drops, dust and knocks.
• Best for travel and school bags → Lebakort Hard Case Compatible. The hand strap and quick zipper make it easy to grab and go.
• Best for keeping cables and small accessories together → Lebakort Hard Case Compatible. The double mesh pocket is designed to hold wires and peripherals without them escaping.
• Best for a specific headphone model → depends which one you own. Koss KPH7 → YDYBZB KPH7. iClever HS19 / BTH12 / BTH26 → Lebakort Hard Case Compatible.
• Best if you own neither headphone → neither. Both are accessories tied to particular models; check compatibility before buying.
• Best for a quick, low-commitment upgrade → YDYBZB KPH7. It is a small foam part that refreshes something you already have.
For office use, I would buy the YDYBZB KPH7. In my opinion, comfort is the spec that actually decides whether you keep a portable wired headphone on your desk, and five pairs of soft, breathable foam cushions address the single part that degrades fastest. It is a straightforward, low-risk fix for anyone who already owns the Koss KPH7 and wants it to feel fresh again.
The Lebakort case is the better buy if — and only if — you are protecting iClever kids' headphones. It is well thought out for that job, but it does nothing for comfort, and it will not fit a Koss KPH7. Match the accessory to the headphone you actually own, and check the current price on Amazon before you commit.
FAQ
how to connect mobile headphones
how to connect c port headphones
USB-C headphones are typically plug-and-play on devices with a USB-C port — you connect the cable and the device recognises them. Bear in mind that the YDYBZB KPH7 is foam cushions only, with no connector of any kind, and the Lebakort case is storage only. Neither product connects to anything.
how to pack headphones
For kids' wireless headphones, the Lebakort case is designed for exactly this: the iClever headphones sit in a shaped compartment, cables and small accessories go in the double mesh pocket, and the hard shell with nylon, EVA and goose-down lining protects against dust, knocks and light moisture. The hand strap makes it easy to carry.
how to use external headphones on mac
Plug a wired headphone such as the Koss KPH7 into your Mac's headphone jack, or select a Bluetooth headphone in your Mac's sound settings. If the pads on a wired pair have gone flat and uncomfortable during long desk sessions, that is the problem the YDYBZB KPH7 replacement foam is intended to solve.
