I'm curious as to how deep people typically insert these? I typically opt for a slightly bigger tip and get a seal that isn't as deep for most of my IEMs.. but considering the success i had with the DBA-02/Comply deep insertion.. I tried it on all my IEMs last night and was really surprised at how much more I like the sound.. mids are more forward across the board and treble is less harsh.. the HJE is included in this.. I used the smallest silicone tips from the Silver Bullet tip set so I can insert the Panny quite deep, getting a seal about as close to my ear drum and love how they sound.. soundstage narrows slightly but the mids came forward, treble sounds better textured and the bass is more balanced.. I'm definitely feeling this kind of sound.. and lord only knows how good the custom will sound if this is the kind of fit I can expect!
