    2 of 5 uses a lot of battery Saturday, July 05, 2008
    A Customer from Salt Lake City, UT  

    has on/off switch to activate noise cancelation. If you forget to turn it off after using: the battery will be gone within a few days: Very inconvenient Furthermore, in my package was do description included how to change the batteries which are essential to use the headphone, I had to search on the internet for 20 min

    4 of 5 Sounds great, a little cheap on headset Monday, May 12, 2008
    William J Swartz from Brentwood, TN  
    This Koss headset sounds great. I can hear minute details of intstruments (and I don't hear real well). There were no instructions as to how to open the unit to install the batteries. I had to go to the website to find out. The structure of construction is a little cheap. (plastic) it makes me think that I might break it sometime if I am not careful. Overall for the price this unit works very well.

    5 of 5 Koss QZ-pro Thursday, April 12, 2007
    A Customer from Chicago, IL  
    Great sound. Dramatically reduces external sounds. Buy.com was fast and reliable in filling my order. I would recommend both.

    5 of 5 Excellent Sunday, February 11, 2007
    Strykyr from Millville, NJ  
    Looks good. Sounds better. Koss makes good stuff and these prove it. Noise canceling drowns out computer fan noise and automotive heater noise. Good bass response. Was listening to a song last night and actually heard the guitar pick striking the strings. I couldn't have done better for my buck.
