The JVC HAS400 sounds much better than the Portapro. The Portapro sounds murky and lacks treble. The HAS400 has great detail, and sounds very balanced.
Does the JVC HAS400 provide good isolation and is good for library/work use? I am worried about the leakage. Thanks!
The HAS400 doesn't isolate outside noise that well even though it does seem to be closed, however sound leakage is not a problem.
