IE 800 review is up on InnerFidelity for anyone interested: http://www.innerfidelity.com/content/sennheiser-ie-800-dynamic-ear-monitor
I’ll add it to this thread in due time. For what it’s worth, I prefer its sound to the Ultrasone IQ slightly but still like the K3003 better.
Interesting. Looks like the GR02 BE.
Is that the best of the Zero Audio IEMs?
I tried contacting them once about one of their old single BA models but I think the language barrier was an issue. IIRC their website was all in Japanese back then.
You can go to the interactive table and select “With Mic/3button remote” to see everything I’ve reviewed with a 3-button. I’ve done that filtering here.
The UE900 becomes one of the top choices in that case.
