after some google ![Red Eyes :red_eyes:](https://board.marlincrawler.com/Smileys/marlin/red_eyes.gif)
im 95% sure its TG
but all in all they last iv had buds that have been using them with no issues they use "A special retainer ring securely stabilizes the main bearing to prevent bearing play" instead of the double bearing setup
The bearing cage doesn't move in any adapter, it's the single row bearing that has play and develops more play as time goes on.
