Tin Audio T2 Pro. Comes out Monday for pre-order on Massdrop. Packaging is the same. Cable 3.5mm barrel is bigger. There are still vents inside and outside. The only noticeable difference is the ear canal screen is now inside at the bottom of the canal and larger holes.
If you look closely, regular T2 has this same cover inside - visible through the mesh on top of the nozzle.
