"Amazing Sound. Extremely Comfortable. Very Portable."5.0 starson by menotquilty
Pros: See Above, and add CHEAP
Cons: Minor Sound Leaking
Summary: I purchased these headphones at the same time that I purchased a pair of Sennheiser HD280 Pros. The Koss PortaPros sound better, are more comfortable, much cheaper, and more portable. If you demand sound-isolation, the HD280's are still a good choice. But, these PortaPros don't leak as much sound as my old Grado SR-60's, which I learned the hard way are not really meant for public use (too long of a cord, and way too much sound leakage). The Koss' strike a perfect balance of price, sound, comfort, and general use.
