i have cable down but only 3.5mm, i use final audio E tips
i might need to find one with 2.5mm jack
Well before u spend cash on a 2.5 mm straight cable, why don't u try the 3.5 mm one with a cable down position and see if it suits your ear anatomy.
I find Final Audio E tips aren't as "long" as the Spinfits so I still prefer Spinfits to gain some extra grip inside the ear canal by virtue of their nozzle length. But as usual YMMV, eartips are as individual as shoe preferences.
