I first buy a pair of the Koss Titanium Portable Headphones back around 6-7 year ago . that same pair have last I all this time until a week or two ago when they finally give up , I quickly order another pair and be hope for the same result 's . I also have other 's in my family that use they aswell , they really come in handy when I be work at a computer and need to be able to hear outside of the headphone . other than that , I like the volume control , how they feel , they lightweight design , the clarity of the sound , they have a nice bass sound to they , and more . but the best part of they be the price ! with shipping , they $ 20 , it be insane ! if there be anything bad about they , it would be that after 7 year they croak , but consider the price , and all that you get out of they , it be worth it . EDIT : I recieve my new Koss Port . headphone in and they fit and sound perfect , the only complaint I have about the new one be that they do not have a l-plug , but for the price , I 'll get over it . pro : Long Life Price Sound quality volume control how they feel how they look con : no l-plug if you need cheap headphone for listen to a mp3 Player or use on a computer , I would highly recommend the Koss Titanium Portable Headphones .
