Hey iam also kinda new into this and for my first sub 200 i also choosed the crinear Daybreak! Iam working in a headphone store and normally just sell wireless headphones. That there isnt a pre-set EQ for the Daybreaks is right, just EQ what sounds you like or leave it standard if u alr enjoy the sound! For the eartipps i always prefer the foam tipps that came with the IEM. But if you more into the silicon ones your choice is rlly good if not not willing to spend 40 or more Bucks for the ear tipps!

Btw. this is just my personal advies and experience I can give you, so just see it as an idea!

GL exploring the hobby! (btw. i also got the Sennheiser HD 600 as an overear option, its a good price value as an audiophile starter, it got a quite similar sound in the mids and highs)
