Nowadays (as of 2025), these microphones are often sold on online sales platforms, and the pictures in the shop are correct (the "441" imprinted on the component itself). However, upon receipt, you discover that it's a different type (and upon inquiry, the sellers reply that it's 100% compatible) or one that looks correct but doesn't work at all or only works poorly and is probably a cheap replica. Since you only notice this after soldering the pins, you can't return the item. Therefore, we recommend using shops (e.g. this) or sellers that also offer a soldered/tested version. Then it's more likely that the unsoldered version sold by that shop is also genuine/good.
