I bought these headphones toward the end of January 2010 and I would say that I am impressed. The are a very good value for the price. In my opinion they are much better than than the other 'budget' priced headphones out there. I paid about 13 bucks, maybe 10...(cant remember and dont wanna check). I received black ones with a straight plug not the angled type shown in the Amazon picture.Let me put this out there, I use these mainly for listening to audiobooks. I do not use these for music very often, but when I have, they have sounded very good. Not too much bass as others have said. I really do think that these are good for almost all stuff. I have listened to instrumental (digital variety), to real classical, to Rob Zombie and the RHCP's. I think that it all sounds pretty good. I think that they hit all the ranges in a complete blend, there is not one sound that sticks out more than the other. This could just be my ears though as others have said "too much bass."They have a relatively large body when compared with other newer in ear headphones but are not too heavy. The foam tips are not a standard design that can be replaced with normal silicon tips the way Skullcandys or JBuds or lots of others can. This is about the only negative thing I can find about these headphones. I got used to the silicon from my cheapo skullcandys. I like the foam but since it is not a standard size you either will have to replace the tips by purchasing more or just buying new headphones when they get destroyed beyond use. The tips may last a while but I feel like they are gonna get 'bad' after a few months of use (I am at about 1 month, but I use them 3-5 days a week). I also bought another set of headphones at the same time and these are my choice for everyday use. The others have been relegated to back up duty in case these unexpectedly break or I leave them at home on accident.Since I made the overt comparison, the other came in an electric blue color w/ a free case. They were priced similarly so I think it is fair to compare them. Lets just say the others are not bad but they are a spare set for a reason. Also since I mentioned Skullcandy as well, these Koss The Plug sound better than the 3 Ink'd pairs and probably better than the Titans (older model Titans w/ no inline Vol control...it has been about a year since they broke, but in turn the Titans sounded much much better than the first pair of Ink'd I had and moderately better than the second set). The 3'rd set of Ink'd were purchased for use while these Koss were shipped otherwise I would not have bought them again.Overall I would give these a 4.5 outta 5. But a 5 for the Amazon review since no halves. I think that the wire which is thin (surprisingly little cord noise or maybe it is just easier to tune out than the 'backups') will most likely break at some point. Also the idea of replacement tips detracts a little, but for the price in my opinion these are by far better than the $25-60ish retail price for the Skullcandys I have tried and the $50 MSRP of the spare electric blue set sold on Amazon.Also I did not just opt for these because they were cheap, people mentioned that they were some of the best sub 100 headphones you could get. And I was looking in the 50-100 range but just didnt feel the value was good enough to justify the purchase price. If I am gonna have crazy cord noise and broken wires and faulty speakers why not 'risk it' with these.
