Still not a big fan of these after almost 2 years of trying. They lack detail by default and when you play with the EQ to "add it back" the result is unpleasant, sibilant and harsh. Thank God they were not expensive.
If you wonder, the less expensive CHU II sounds clean in the same areas. Pristine actually. Bass is also better, especially after a bit of EQ. Should I mention the CHU II is smaller, easier to fit (Comply foam tips for me) and consequently significantly more comfortable to wear than these Zero Blue?
