Eidolic E-STB Modular Titanium Barrel
For 2.5mm, 3.5mm, 4.4mm Eidolic plugs and more
This page is for the barrel only.  For complete plugs, hit the link below.

The world’s first connector barrel to allow true modular functionality – customize appearance, material, and length with a quick twist!  E-STB comes in two parts with two inserts included per barrel purchase.  The upper part features a laser-engraved Eidolic logo and screws securely onto the lower part.  Slip your choice of carbon fiber (10mm length) or metal (5mm length) tubes onto the threaded lower part and the barrel is ready to screw onto Eidolic’s 2.5mm, 3.5mm, and 4.4mm contact pieces.  Sold standalone here if you get the urge to upgrade after buying an Eidolic connector or if you have compatible connectors on hand.  Fits any contact piece with M9P0.75 threading.  Price includes choice of 1 carbon ring plus 1 metal inlay ring.

Also available as an add-on for Eidolic’s 2.5, 3.5, and 4.4mm plugs:


6Al-4V titanium alloy, CNC processed

Fine circular polishing finish

Smooth chamfered edges

Laser-engraved Eidolic logo

Choice of carbon fiber ring (black carbon fiber, silver fiber, and more to come in the future)

Choice of metal trim ring (high polish silver aluminum, high polish bronze)

Use either carbon fiber or metal – the length of the ring you choose makes the barrel longer or shorter.  Or, screw the barrel all the way together for a very short, minimalist barrel – the 3 way design offers short, medium, and full length connector styles to suit any application.

Includes Eidolic gray silicone custom grommet to seal the back opening.

If the threads are not locked with glue, the barrel can be used and re-used and the decorative inserts swapped.  Just seal up the solder contacts area with hot glue, wrap with Teflon tape, screw the barrel on, and insert the Eidolic grommet into the back of the plug.
