Koss QZ 77

Advantages: many- sound, comfort, looks, durability
Disadvantages: can`t think of any

...Some interesting facts: the Koss Portario headphones were first introduced in 1984. Over the years the company preserved their original design but improved their performance. I have been using the koss products for years now, mainly buying it from koss.com as sometimes it is difficult to find them in the shops. Once I got a pair of headphones on ebay but was disappointed as it said that they were brand new but they obviously weren`t. The porta pro head phones deliver exceptionally deep bass and wide frequency response from 15 - 20,000 Hz. The main advantage is that most elements are constructed from mylar which minimizes the distortion of the sound.

Advantages: great bass, stays in ear better than most and great price
Disadvantages: wire gets tangled, may not fit everyone's ears

Don't worry, cushioned rubber ear pads make this design comfortable. Basically, before you place them in your ear, you scrunch up the ear pads. Once inside, they expand to fit your ear and provide the seal that aids the quality sound. Some reviewers have reported discomfort, but I find them comfortable enough.Tthe other major advantage of The Plug's design is that they stay in your ear. Every few months, the ear pads wear out, but Koss provide a number of spares in the same pack which should last for a number of years. One word of warning - the sound isolation provided by The Plug really is effective, so watch out for traffic as you probably won't hear... Read review
