I was in a similar situation as you a few months ago. I'm also from Canada (Toronto)
I was looking for a CIEM or Universal IEM that would be well suited to a wide variety of genres.
The main reason I decided against CIEM is bc of the risk. First there's a risk that the impressions may not be good and also you run the risk of not having a perfect fit. Shipping back and forth from Canada to US/Asia is not cheap and can add up quickly. Also we get hit pretty hard by customs/taxes.
I ended up going with the 1plus2. Ordered from Musicaaccoustics in Japan. Best part is shipping is included (trackable) and was received in 3 business days. Absolutely no tax or duties to Canada.
Fitear TG334 would be another good option for universals.
May I know how you managed to get the 1plus2 from Japan, do you have a Japanese address? Which company did you buy it from? Thanks
