  • They're called Pro for a reason

    I am a retired radio engineer. These phones are the updated version of phones I used for years on air and later doing sound reinforcement professionally.They sound precise, are heavy and good at sound isolation.What they ARE NOT, is consumer phones for use with an Ipod. The Ipod nominal impedance is low, 32 ohms. These are professional grade 250 ohms. Many higher end consumer products like Harman Kardon are designed for higher impedance earphones, Ipods are not.

  • Buy them!

    I bought these for my husband who watches movies/tv/videos online - to all hours of the night. Would definitely buy them again - especially after reading reviews on another site that says Koss warranties them for a lifetime and these have been around for years.

  • Studio Sound

    The frequency response is great on these headphones. They look great and are built tough. The only downside to these is the weight. At about 2 pounds, they are a bit heavy for someone with a small head; but for the value, I absolutely recommend them.

  • Koss Headphones

    This is a great product, extremely comfortable when wearing and the sound quality is excellent. Even though they are meant for the studio they hold up well when plugged into a computer or ipod. The audio is crisp and outside noise is blocked out 99%. Highly recommend!
