These are NOT light, NOT small and not the most comfortable.
BUT they are the absolute best noise blocking headphones I have ever used. They are Noise blockers first, headphones second.
I use mine to listen to music while I mow my lawn, I also wear them during target practice. I would not use them for travelling or in the office but thats ok.
Every one who mows their own lawn, works in a machine shop, or works around very loud areas should own a pair of these. Protect your hearing and listen to music at the same time.
Now for the bad news - the sound quality from these headphones is mediocre at best and they can be uncomfortable to wear. Bass response is very poor - and if you try to accentuate the bass, you'll get an annoying rattle in both earpieces. Since the sound elements can't keep up, I really don't believe they would hold up long with boosted-bass settings. The treble also seems just a bit clipped... I'd characterize the sound as slightly "muddy" in general. These are by no means "audiophile" quality headphones - I've had inexpensive headphones from discount stores that could easily match - and, in some cases, exceed - the sound quality of the Koss QZ-99's.Read more ›
They look tough but I doubt they could handle a weekend at NASCAR, for which I bought them for. I was using them for music and radio when they shorted out on me.
However, the warranty on them says "Lifetime, No Questions Asked!" ...So I will check that out, send them in, and see what happens. If Koss can get them back to me in a quick turnaround, I'll knock my rating back up to a 3.
I sent them in to the company and got an extremely quick turn-around, back and working good. Next test - NASCAR.
I'm not saying KOSS isn't a great headphone maker, but if your looking for something soundproof avoid these headphones. If your looking to block out ambient noise and the majority of sounds then these are definitely yours all the way. Very comfortable and well made, KOSS is an amazing company I was looking for total soundproof protection though. In the end I kept them and still use them for my music. I very much enjoyed this product and highly recommend it to anyone out there.

I've bought nine of these and every single pair leaks mineral oil. I also noticed that the last three I bought didn't block noise as well as the older ones. Read morePublished 1 month ago by C. G.

A little heavy for the home use. A tight fit on my head made them a little uncomfortable. Sounded great but sent them back.Published 1 month ago by Dan Koehler
These are high-quality. From the packaging to the product, i was impressed. Durable. The cord is long but curly so it doesnt get in the way. I use these at NASCAR races. Read morePublished 2 months ago by Matthew L Croft
