"Superb sound and comfortable to wear"4.5 starson by citizen_can
Pros: I loved my three pair of Sennheiser PX100's scattered about the house but decided to give the PortaPros a try. I still love the PX100's but find myself using the PortaPros most of the time, especially for the bass response and comfort.
Cons: The hair-snagging snafu is real but was solved through high-tech application of one piece of Scotch tape to hold the top slider in place. This might not work for those needing to pack and carry, but it works well for me.
Summary: As noted, the bottom line is these small wonders sound superb! I had my doubts when ordering them, but for $35 at Amazon, I figured I couldn't go wrong. From the first listen, I knew I had winners. I'm no audiophile, but I expect excellent sound, and these phones delivered. Once the hair-pulling problem was solved, I noticed they are the most comfortable headphones I've ever worn. They sit so lightly I almost don't notice them at all. I love the retro look and find the cutaway design just above the pads makes it easier to don them and to get left-ear/right-ear placement perfect every time. They are so small they don't look nearly so clunky as they appear in the pictures. The article and commenters have said enough about the sound that I have nothing to add. But I do plan to add one or more two more PortaPros s to my collection. BTW, the only reason I didn't give them a full 5-star rating is because of the hair-pulling thing. I still have a bald spot from that first depilation. (j/k) This seems like a defect Koss could somehow correct.
