[PA] - Looking for IEMs - Replacing my Rock Zircons.

Hey reddit,

Since my Rock Zircon's cable is broken I am looking for a nice new pair of IEMs.
Here is what I'd be looking for:

Budget:
100€ - hard limit

Source:
iPhone 6 (Huawei P10 in the future maybe) and my laptop
Maybe my PS4 if I can't find my gaming earbuds xD

Requirements for Isolation:
I will use them on public transport most of the time and at work -
when I'm at work i only have one of them in so good isolation would be nice.

Preferred tonal balance:
Well i have Rock Zircons which tend to have a little too much treble but the bass was fine.
So i guess V-shaped with lower highs or bassy..?

Preferred Music:
Pop Electro Chillstep Ambience

What would you like to improve on from your set-up?
I'd like Rock Zircons with less treble and a wider soundstage..
They should give a nice grin on my face when I first listen to them :)

Location: Europe - Austria.

Kind regards
