Pros Flex-i-bend metal frame, allowing you to bend the koss to shape to your ear. Open headphones for more ambient sound, and a more spacious bass. Incredibly cheap in price for such amazing sound.
Cons Very tacky finish; may be uncomfortible to some if the metal frame clip isnt bended.
Summary The Koss KSC-75 are basically the standard for those who don't wish to spend a lot on headphones but want to take a taste in the audiophile world. Granted the KSC-75's are amazing set of headphones, they are not monitor quality due to there more pronounced bass. They are really just a fun sounding headphone. A problem with them to some is that they are open headphones so people can hear what you are listening to, and are no way noise cancelling, so if you don't care if people hear your music or you want don't want to be isolated from the outside world go ahead and get them. The KSC-75 can rank up with some other more expensive headphones to when paired with a headphone amp, which is pretty insane considering they cost from 9.95 to 19.99. Another plus is Koss's famous no questions asked lifetime warranty. If you plan on just plugging these to an ipod or other mp3 player just do yourself a favor and get them.
Pros Comfort, price
Cons Sound quality
Summary For the money these earphones are a great value. The are comfortable to wear for long periods and while the sound isn't top notch, neither is the price. I have had these for six months and have tried to find a replacement that might have better sound, but haven't found any that are as comfortable and still affordable.
