The E1001 aren't the most open-sounding, you will notice that when you listen to tracks which are made to make you feel the spaciousness and openness, such as Coldplay’s “Paradise” and Emeli Sande’s “Heaven”. But the detail is brilliant, I even enjoyed a full hour of American country music on the radio, and I am normally no fan of country. I also did notice some harshness and dryness while playing Drake’s “Hotline Bling” and some old British Rock songs, and there can be some unwanted metallic feel sometimes, but above all, the E1001’s sound is rich, warm, and full of intricate detail.
