You will not have any trouble from Etymotic ER4s/p.

So...pretty much everyone thinks that I should get ER4P(or S with P adapter) with custom mold instead of UE4 pro?

Thanks guys! Jason.

no one?! Any input is greatly appreciated...! Jason

Could you please help me choose between the two? If I am getting ER4S, I will be getting the custom ear mold. Just for your reference, I have not tried any of the ultimate ears series, but I do own ER6 and just love the sound signature of it and I thought the time has come for me to upgrade...

I just purchased d2+ boa and is on its way to Canada. But, I am just wondering, if d2+ boa is op amp swappable?! Any comment on that would be awesome! Thanks

I placed the order yesterday, and its been a day, and I still have not gotten any replies from them... should I be worrying?? I live in Canada...do you think it will take a long time for it to get here?! I REALLY hope it arrives soon.
