Do earbuds like these: http://www.aliexpress.com/item/2016-New-Original-****-PK1-15mm-Driver-Speaker-Unit-With-Shell-MMCX-Connector-In-Ear-Earburd/32653345463.html use the actual PK1 driver or are they just trying to sound the same?
That earbud doesn't use the PK1 driver as far as I know. It's bass light with decent mids and highs, but didn't impress me. I'd use it for classical music.
