Just received mine today "Wide soundstage, full-bodied bass".Very good description.  This sounds like big can, I am very impressed. 
Thanks for your review, i saw you were a Tenore owner, so i could not go wrong.
Can't believe Oneplus Icons has only one drive unit inside.

@bonson Thanks for the feedback mate, and congrats on the Icons. They are really something special, still impress me every time I put them in my ears. Please feel free to post your views in the Impression thread here - http://www.head-fi.org/t/794763/oneplus-icons-revews-pics-and-impressions-thread.
