“I bought these becuse they seemed high tech and were 75% off. They were strangley not comfertable or user friendly enough for me to put more than 30 hrs on them.

“Looking at the picture of the PK3's I wasn't expecting much. They look and feel cheap using a generic case for the drivers making them easy to fake.
