Pros:As comfortable as a set of whole ear headphone will ever be.
Cons:Thudding, indistinct Bass with no character...washed out Upper range.
For $15.00 to $20.00 more you can get a set of headphones that actually have some dynamic range to them.
The KOSS UR20 headphones are comfortable but that's about the only recommendation I can give them.
Otherwise they completely lack any real Low Or High Dynamics.
