Everything functions properly, and I’m pleased with my purchase.
【For DIY/Unused】Knowles SWFK-32625 (1 Pair) *Resale prohibited
Product Details
This is a pair (2 units) of Knowles dual balanced armature drivers, model SWFK-32625, for DIY earphone creation and repair.
■ About the Origin of This Product
These are real deal spare parts I had in stock for hybridizing 1DD (single dynamic driver) earphones.
Currently, they are difficult to obtain due to rising raw material costs, but I am listing them as I organize my workshop, hoping to pass them on to fellow makers who truly need them.
■ Condition and Honest Disclosure
These are unopened and unused, but no special selection (pairing) process has been performed.
As shown in the second image, they were cut from a bulk pack with a label from a legitimate source (Soundlink).
I have no intention of embellishing this with flowery language. Please consider this only if you are looking for the real thing and are familiar with the specifications.
■ For Search and Compatibility
These have virtually the same specifications and size as the popular SWFK-31736 for DIY projects.
I confidently recommend these as an option for those who know the real thing, whether you are looking for the 31736 or considering enhancing the high frequencies of your hybrid earphones.
■ ⚠️ Response to Reselling and Hoarding ⚠️
Please limit your purchase to one set (one pair) per person.
I will cancel transactions for multiple purchases, accounts that appear to be for reselling purposes, or if I determine from transaction history that you intend to relist at an inflated price.
I would like these to go to experienced individuals who are familiar with handling balanced armature drivers, including heat management during soldering.
■ Shipping
I will ship them quickly in a padded envelope.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
