How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired in-ear monitor with a balanced, audiophile-style tuning and a metal build, choose SoundMAGIC E50; if you need to restore a pair of Sony MDR-M1 studio headphones with fresh ear pads, choose SOULWIT Earpads Replacement. These two products do not compete for the same job, and that is the most important thing to understand before you spend anything. One is a complete pair of wired earbuds. The other is a maintenance part for headphones you already own.
• SoundMAGIC E50 — biggest strength: A genuinely balanced, high-resolution sound signature in a full aluminum housing, with a 10 mm dynamic driver and a tangle-resistant twisted cable.
• SoundMAGIC E50 — biggest trade-off: It is wired, has no microphone, and relies on a physical 3.5 mm jack, so it will not work with phones that dropped the headphone port without an adapter.
• SOULWIT Earpads Replacement — biggest strength: High-density memory foam wrapped in soft protein leather, cut specifically for the Sony MDR-M1, which is exactly what worn-out pads need.
• SOULWIT Earpads Replacement — biggest trade-off: It only fits the MDR-M1. If you own any other headphone, this product is simply not for you.
• Who should buy the E50: Listeners who want accurate, natural sound for music, monitoring or critical listening on a wired connection.
• Who should buy the SOULWIT pads: Sony MDR-M1 owners whose original cushions have flattened, cracked or lost their seal.
The SoundMAGIC E50 is a wired in-ear monitor built around a single 10 mm dynamic driver. The spec sheet lists a 20 Hz to 20,000 Hz frequency range, 51 ohm impedance and 102 dB sensitivity. Those numbers describe a headphone that wants a bit of clean power rather than a featherweight signal, and that rewards a decent source. In practice, that means a portable player, a laptop, a DAC dongle or an audio interface will get more out of it than a weak onboard output. This is not a bass-cannon tuning. The design brief here is balance: strong but differentiated low end, tidy mids and clear highs, with no single range pushed forward.
What stands out to me is the physical build. The housing is full aluminum, not plastic dressed up to look like metal, and the plug is angled at 60 degrees to relieve bending stress at the cable joint. The pins are gold-plated, and the cable uses a twisted multi-strand core with an anti-tangle design and shielding against radio frequency interference. For a wired in-ear, that combination matters more than almost anything else, because cable failure is what usually kills earbuds first. The in-ear shape is a rounded tip that seats into the ear canal, and SoundMAGIC ships a real accessory set: two types of S/M/L silicone tips, a double-flange silicone tip, a medium foam tip, a cable clip and a hard carrying case.
Who should skip it? Anyone who needs a microphone for calls, since the E50 has no mic. Anyone who lives on a phone without a 3.5 mm jack and does not want to carry an adapter. And anyone who wants a thumping, bass-first signature — this is a balanced earphone, not a party earphone. It also carries a 1-year warranty, which is worth noting for a wired product that will see daily use.
SOULWIT Earpads Replacement: Who It's For
The SOULWIT Earpads Replacement is a single-purpose product, and I mean that as a compliment. It is made exclusively for the Sony MDR-M1 Professional Reference Closed Monitor Headphones. SOULWIT is explicit about this: verify your model before purchasing. That is the whole ballgame. This is not a universal pad that "kind of fits" a range of headphones — it is cut for one model.
The materials are the story. High-density memory foam covered in soft protein leather. Memory foam is the right choice for headphone pads because it recovers its shape instead of staying compressed, and density is what keeps the pad from collapsing into a thin pancake after months of use. Protein leather is the standard synthetic covering for this job: it is soft against the skin, easy to wipe down and holds up to regular wear better than cheaper vinyl alternatives. The color is black, matching the stock look of most studio headphones.
Installation is described as straightforward, with a clear guide included. That matters because pad swaps on closed-back studio headphones are usually the moment people give up. If you have ever fought a stretched lip around a plastic ring, you know the frustration.
Who should buy it? Sony MDR-M1 owners whose pads have flattened, cracked, flaked or started shedding. That is the classic failure mode for any headphone pad, and it changes the sound more than people expect: a collapsed pad shortens the distance between driver and ear, which typically tightens the soundstage and shifts the tonal balance. Replacing worn pads is one of the cheapest ways to make a headphone feel and sound new again, and SOULWIT frames this product exactly that way — revitalizing the headphones and giving them a fresh look.
Who should skip it? Anyone who does not own the Sony MDR-M1. There is no version of this that works on another model. Also note there is no stated warranty on this item, so treat it as a consumable part rather than a long-term covered purchase. If you are unsure about the current price, check it on Amazon — the page has a button for that.
Side-by-Side: Which Should You Choose?
• Best for repairing what you already own → SOULWIT Earpads Replacement. It exists to bring a worn MDR-M1 back to life.
• Best for build longevity → SoundMAGIC E50. Aluminum housing, 60° angled plug, gold-plated pins and a twisted anti-tangle cable all target the parts that fail first.
• Best for a specific headphone model → SOULWIT Earpads Replacement. Made exclusively for the Sony MDR-M1, so compatibility is guaranteed only there.
• Best for comfort over long sessions → tie, for different reasons. The E50 uses ergonomic in-ear tubes and multiple tip types; the SOULWIT pads use high-density memory foam and soft protein leather.
• Best for calls and voice chat → neither. The E50 has no microphone, and the SOULWIT pads are not electronics at all.
• Best if you need isolation → SoundMAGIC E50. The sealed in-ear design excludes ambient noise when you get the tip fit right.
• Best if you want a complete product, not a part → SoundMAGIC E50. It arrives with ear tips, a cable clip and a hard carrying case.
In my opinion, most readers searching this comparison should buy the SoundMAGIC E50 — because it is an entire, self-contained product with a purpose-built aluminum body, a balanced tuning and a genuinely useful accessory kit. It is the only one of the two that stands on its own. But if you own a Sony MDR-M1 and your pads are shot, the SOULWIT Earpads Replacement is the smarter purchase, since no amount of new earbuds will fix a worn-out headphone pad. Buy the E50 if you need sound. Buy the SOULWIT pads if you need to restore the sound you already have.
No. The E50 is listed as a no-mic model, so there is no built-in microphone and no inline control for calls. It is a listening earphone, not a headset. For calls you would need a different product with a mic.
No. SOULWIT states the pads are made exclusively for the Sony MDR-M1 Professional Reference Closed Monitor Headphones and advises verifying your model before buying. Assume they will not fit anything else properly.
They are not comparable in that way. The E50 is a complete earphone with a 10 mm dynamic driver, 20 Hz–20,000 Hz range and a balanced signature. The SOULWIT pads produce no sound themselves — they restore the seal and cushioning of an existing MDR-M1, which affects how that headphone sounds.
It depends entirely on what you already own. If you need a working pair of earphones, the E50 gives you a complete product with tips, a cable clip and a hard case. If your MDR-M1 pads are worn, the SOULWIT pads are the cheaper way to avoid replacing the headphones. Check the current price on Amazon for both before deciding.
