  • Best passive I have had

    Hey all, I am a professional drummer who is always looking for quite ways to practice. I currently have an electronic Drum Set that I use to practice with while at home. These head phones work great with it. It cuts out the tapping sounds the sticks make on the rubber pads. I will also wear them an hour at a time and there is never any discomfort. Bass and treble come through really well and the volume adjustment on the headphones themselves come in handy when I need that extra boost of volume. The only downside is the cord, its coiled but it can stretch out. Its not really an issue, I'm just not a fan of coiled wires.

  • Amazing quality for a great price!

    I am a student with a shared study space that is convenient, but less than quiet most days. The noise cancelling on these headphones is phenomenal. People have to be positively screaming for me to hear them with these on. Sound quality is excellent as well and the volume knob on one of the earshells is really convenient.

  • GREAT HEADPHONES

    THESE ARE GREAT HEADPHONES. GREAT ISOLATION AND TONAL QUALITY. ALSO A GREAT VALUE.

  • New Stereo Headphones

    My husband and I just got new headphones for our stereo, and now when we listen to our cassettes and CDs, they sound so clear! This is the best thing we ever bought, and I'm so glad we got it from O.

  • Noise Cancelling is Right!

    When I put these headphones on, I can look right at someone talking to me & not hear one word! I ordered them for work, where the noise & chatter is a distraction. THESE ARE PERFECT! The audio quality is not stellar. As suggested by the details page, where it says "Ideal for use with racing scanners and metal detectors" (not music). Don't get me wrong, the sound is fine for music, but nothing to brag about. For awesome sound AND awesome passive noise cancellation, you'll have to upgrade. I had a pair of Audiology headphones that were about the same price, and they broke after 4 months. Koss is good quality; I hope to enjoy these for a long time!

  • Bulky, heavy

    I really should have returned these, but I am just too lazy. They feel too heavy on my head and I want to take them off after several minutes. They look great. But if you love bass like I do, forget it.

  • Awsome

    These headphones have great sound. They have a switch for stereo or mono so the sound is premiere for both music and just voice. The volume control on the side of the headphone is very useful when you need to here someone talk to you or to control when you are not in a loud situation like mowing. I am truley satisfied with everything about these headphones.

  • Great for the price

    Product came exactly as described. Work well, maybe a little larger than you might think, but definately get the job done.

  • Heavy

    These headphones are heavy and bulky. You can't rest them on your neck when you need to take them off for a short period; they're too big to do this. That may not be a problem for everyone, but I work with headphones on and need to remove them often for just a second. The sound quality is good, as well as the noise canceling aspect. They are not adjustable. My head is average sized and I get a slight headache when using these. Hopefully I can break them in and they'll loosen up a little.

  • great!

    I bought these headphones for a recent trip to Japan. It was the best decision I ever made. Although they aren't the quality of Bose, they're great for the price. Good sound and excellent noise cancellation really helped me out. I would suggest these for travel or for real music lovers who don't want any distractions.
