Additionally, Koss decided to use a really cheap-feeling cable with a stiff plastic covering that never straightens out

But it's not soft pliable plastic

For this price you cannot beat KOSS PP on sound quality, it has crappy plastic material, but so easy and light to take with you on a trip.

I just got my second pair back, and that SAME piece of damn plastic is already SUPER loose on the right only after two hours at the gym.

Upon opening the package the headphones seemed flimsy and fragile being they are made with hard plastic

Inside, the headphones rest in a black plastic shelf, with a clear plastic cover

However, the plastic tends to break on the ear pieces and just hangs

At first glance the plastic and metal seems a little flimsy

since the prices fluctuate, on the website they look like cheap plastic, and would fall apart on

The hinges seem to me made from cheap plastic that wont last long.

These capture some of the issues but its hard to explain the feeling of what appear to be tight manufacturing tolerances and warped plastic.

excellent as before

The only thing I think the Portapro's could improve on are comfort and perhaps a removable/replaceable cable(s

cheap，I like it
