Hello everyone!
I'm back and I'm VERY happy to report that my fit/comfort problem has been 100% solved and I've been enjoying these IEMs how it was intended
For those that don't know, I couldn't really get any good fit with the provided tips and tried alot of others untill I found a pair of random medium sized ones (I think it was the tips from the RE0 but I'm not sure) that got me a good seal but the comfort was still pretty horrible in long listening sessions. I ended up ordering a pack of original Sony EP-EX10A (aka Sony Hybrids) in hopes of better comfort. Well, I just got them this morning and after a day of trying them out I couldn't be happier!
Both the Medium and the Large ones fit very well and are extremely comfortable for me. The medium ones give me a more clear sound with less bass and the large ones a warmer overall sound (not by much) and with more/better bass, specially sub-bass. I liked them both alot but ended up sticking with the Large ones, the sub-bass is amazing... The large ones provide a tighter seal improving the overall impactness of the music
I won't say these will be the solution for every problem because everyone has different ears but if you're having problems with fit and comfort like I was I can definitely tell you to look into these and try them out if you can. It made ALL the difference for me.
Tips aside these IEM are amazing in pretty much every sense. With the right source/music these shine like no other IEM i've tried out (my experience is not that vast anyway). I still use my EPH100 more because they adapt better to different kinds of music (I usually have a big playlist with all sorts of music) but there are moments when I just want to sit back, relax, and listen to a specific album or artist and the GR07 are just PERFECT.
I'm listening to Fourplay as I type this and I can't seem to get rid of this stupid smile on my face
(Sorry for the bad audio quality from youtube, couldn't find better)
On a side-note, I think i'm going to order some counterfeit Sony Hybrids from
this ebay auction. I can order a bunch of pairs of medium and large only and from what i've read in another topic these are pretty good counterfeits and very similar to the original ones. I'll just keep them as a backup and use them on other IEMs
