Rolling tips tonight and yet again decided to try stock tips but I've finally rulled them out - triple comfort sit well and no pressure build but they suffocate too much. The hybrids give me an instant horrible pressure build, awful trying to pull them out then, certainly won't try them again!
I tried a number of others and ultimately landed back where I started with the grey DUNU tips (sitting on the Sony case pictured below) - no pressure and sound fantastic. Also, very good results with SendaEarfit Xelastec, have them in at the moment and very nice - a little brighter than the DUNU tips as the bore is wider but still excellent bass response... I'll leave these on for a few days for further testing but happy to have another set with success. Oh and surprisingly, the foam tips with a wider bore (towards the back of the Sony case) also worked well, further testing needed though.
My wife and kids think I'm very strange at the kitchen table with a glass of wine and all these bits around me...
