How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to fix a pair of premium headphones you already own instead of buying new ones, choose Komsunma Headphone Speaker Replacement; if you need a complete, ready-to-wear wireless headphone with active noise cancelling out of the box, choose Sxhlseller Headphones. These two products sit in completely different categories, and that single fact decides the answer for most shoppers.
• Komsunma Headphone Speaker Replacement — biggest strength: It is a purpose-built repair kit. Two 40mm 32ohm dynamic drivers plus a Phillips screwdriver and a prying tool let you restore crackling, distorted or silent earcups on a long list of popular over-ear models.
• Komsunma Headphone Speaker Replacement — biggest trade-off: It is not a product you listen to on its own. It only makes sense if you already own compatible headphones and are comfortable opening them up.
• Sxhlseller Headphones — biggest strength: A finished, wearable pair of over-ear headphones with active noise cancelling, up to 40 hours of playtime with ANC on, and 40mm dynamic drivers.
• Sxhlseller Headphones — biggest trade-off: It is a single self-contained unit. If one driver fails years down the line, there is no repair kit behind it — you replace the whole headphone.
• Who each is for: Komsunma for the tinkerer or the owner of a trusted pair of Sony, Beats or Bose cans that still fit well but no longer sound right. Sxhlseller for someone who wants to unbox and start listening today.
Think of this as a spare-parts box, not a gadget. Inside you get two 40mm dynamic drivers rated at 32ohm, running a 20 Hz to 20,000 Hz frequency range — the standard full-range span for over-ear audio. The kit also ships with a Phillips screwdriver and a prying tool, which tells you the intended workflow: open the cup, lift the old driver, drop in the new one, close it up. No soldering iron is mentioned, and no professional bench equipment is required.
The compatibility list is the real selling point. Komsunma names Sony WH-1000XM4, XM3 and XM2, Beats Studio3, Studio2 and Solo3, Bose QC35, QC25 and QC15, Razer Kraken, and "similar 40mm driver headphones." That covers a huge slice of the popular over-ear market from the last decade. If your daily pair has developed a rattle, a crackle at higher volumes, or one side that has gone quiet, this is the cheap path back to balanced sound rather than retiring the whole headphone.
Buy it if you own one of those models, the earcups and headband are still in good shape, and you have basic DIY patience — the kind of person who has already replaced a phone battery or a laptop fan. Skip it if your headphones are a different driver size, if the problem is a snapped hinge or worn pads rather than the speaker itself, or if you have zero appetite for disassembly. The brand lists a one-year warranty and a 30-gram shipping weight, so it is a small, low-commitment package. One more note: the sheet lists Bluetooth, wired and infrared connectivity along with touch controls and a 10-meter Bluetooth range — that is clearly inherited from the host headphones this driver is designed to fit, not a feature of the bare speaker. Treat it as a drop-in part for a headphone that already has those electronics.
This is the opposite kind of purchase: a complete, finished over-ear headphone in Apricot, with faux leather ear cups over memory foam and a foldable frame. The headline feature is active noise cancellation that the brand says reduces up to 90% of ambient noise — a meaningful claim for commuters, open-plan offices and anyone who flies. The 40mm dynamic drivers are the same size class as the Komsunma replacements, but here they arrive already mounted, tuned and ready.
Battery life is the second pillar. Sxhlseller states up to 40 hours of continuous playtime with ANC and Bluetooth both running, and up to 50 hours for standard wireless use. That is genuinely long by over-ear standards and means you can take a week of commutes without hunting for a cable. The memory foam and protein leather padding are aimed squarely at long sessions — the sort of fit you want on a transatlantic flight or a full workday.
Buy it if you want one box, one charge, and noise cancelling without touching a screwdriver. Skip it if you already own a premium pair you love and only need a driver swap, or if you specifically want a wired-only connection — the spec sheet lists connectivity as wired, which is worth clarifying with the listing before you commit if Bluetooth is essential to you. It is a single item, 0.35 kg, and it is what it is: a self-contained headphone with no user-serviceable parts documented.

In my opinion, most people searching these two names together should buy the Komsunma Headphone Speaker Replacement — but only if they own one of the listed models and the rest of the headphone is still healthy. A crackling driver is a cheap fix, and the kit's two drivers plus tools give you a spare for later. If you do not own a compatible pair, or you simply want something new to wear, the Sxhlseller Headphones is the better call: ANC, long battery life and a comfortable folding build in one box. Two different problems, two different answers. Check the current price on Amazon for whichever one matches your situation.
No. It is a repair kit containing two 40mm 32ohm dynamic drivers, a Phillips screwdriver and a prying tool. You install it into compatible over-ear headphones you already own.
Komsunma lists the WH-1000XM4, XM3 and XM2 as compatible, along with Beats Studio3, Bose QC35 and similar 40mm driver headphones. If your model is not on that list, verify the driver size before buying.
The brand states up to 40 hours with ANC and Bluetooth both active, and up to 50 hours for standard wireless use.
It depends on what you already own. If a compatible pair just needs a new driver, the Komsunma kit is the economical route back to good sound. If you need a complete headphone with ANC, the Sxhlseller is the one that stands on its own.
