No matter what I knew custom was better. And its not my first custom iem so I know how it feels and what it does. The good thing is once you get your ear impressions you cane reuse it and save on ear impressions!
My biggest suggestion to you would be a diy hybrid. I had final type e tips and I have torn out the comply foam out the inside bore. Then I simply place it between the slime silicone and the bore. It has best sound isolation and comfort. Cause final type e are very soft. Next thing is maybe stick with little bit of glue underneet the iem. Place a 1 or 2 mm thick foam pad there it will cushion your ears ).
Mine did hurt underneath the iem sooo
Yea going custom is also big step and not always work from first trie. Ussualy for me it take 2 or 3 tries and then they are perfect. Adv almost made it in first shot.
Ier-z1r are heavy its true and not very easy to get accustomed from first week. Try them and if it dont work guess last resort is custom.
For me it was last chance so if custom aint working then bye bye.
Ilisten 5 to 7 hours a days 5 days in a row. So yea it can ve painful as in hell cause the sore spots they build up with time
I am still playing around with them. And while they are definitely not what I would call super comfortable, I seem to be able to get a couple hours out of them without any real major discomfort. But they are definitely not the type so far that I can just put in my ear and forget about. Currently running LL final e tips. I have made the occasional hybrid type before, but I do happen to have some comply isolation around that I will never use, so I may cannibalize them and see if the hybrid foam silicone improves comfort. Personally dont care too much about isolation though because my normal usage is in a quiet office or at home. It was odd too because it seemed proper rotation of the cable actually helped. Angling the earhook away from my ear seems to have helped relieve a bit of the pressure, which was slightly counter intuitive for me, and definitely a shallower fit with larger tips seems to be how its gotta be for these, otherwise, just too many pressure points on my ear.
But, going to keep at them as the sound is really just about right for me. Highly detailed, but not even remotely sharp. Only thing I can say so far that could use some slight slight improvement to my preferences are male vocals which sound just ever so slightly thin. But they definitely are a very nice rich full sound, and the subbass emphasis here is exactly what I was missing from my more recent andromeda golds. And the pairing with the n6ii is quite good, but then everything I have played out of the n6ii sounds wonderful. One nice thing with the z1r though is that they are not super super sensitive. I get a bit of hiss with the andromedas, and there are some wifi interference issues when using the 4.4 balanced output, but they are not audible on the z1r. While I dont necessarily believe that balanced by itself is any better than a well implemented 3.5 SE, I have it available and obviously the 4.4 cable is included with the z1r so I figure I might as well.
