"This earphone set has sound beyond anything I had expected. The quality and price is exceptional. My wife uses the set while working out at the gym and they are so light she does not know she has them on. Would recommend to a friend!"

"I bought these for use with my laptop at my desk. They are a bit bulky for travel, but won't break easily. The sound is great, and I like the volume control they have as well. Price was good, and I used my coupon :-)"

"I am a student with a shared study space that is convenient, but less than quiet most days. The noise cancelling on these headphones is phenomenal. People have to be positively screaming for me to hear them with these on. Sound quality is excellent as well and the volume knob on one of the earshells is really convenient."

Koss-Great Sound/Blocks Outside Noise,
January 26, 2008
By MichgK
from Michigan
"I bought these headphones to use at work where other noises are often distracting. I absolutely love the sound quality and their ability to block ambient noise. They are a little heavy/bulky but I'd definitely recommend them. I'll probably buy a backup set."

"I think I got better sound quality from the El Cheapo small headphones I was using. I like the noise cancelling of these - but the sound is not very bright, it's pretty muddy.
And they are heavy - I wanted to turn them so the headpiece was on my neck, so save my hairdo. But they are too heavy for that. I hope I get used to them and to the sound."

"I'm not a musical professional.
Quality is just ok. I'm not so impressed or dissapointed.
However there are two major problems.
One is it's noise cancellation function make me dull. It's like I am in the airplane.
second is I can feel heat in my ear when I use over 30 min.
Other than these, It is ok."

"No regular earphones stay in/on my ears or head, so I wanted good ones that allowed me to hear my audiobooks above the noise of street traffic, background talking, or a loud boombox. These 'phones are heavy, but when you put them on, it blocks everything. You are in a quiet world! Sound is not distorted. However, if you use these at work, beware--someone may sneak up on you. I'm thinking about getting another headset for home use."

"When I put these headphones on, I can look right at someone talking to me & not hear one word! I ordered them for work, where the noise & chatter is a distraction. THESE ARE PERFECT!
The audio quality is not stellar. As suggested by the details page, where it says "Ideal for use with racing scanners and metal detectors" (not music). Don't get me wrong, the sound is fine for music, but nothing to brag about. For awesome sound AND awesome passive noise cancellation, you'll have to upgrade.
I had a pair of Audiology headphones that were about the same price, and they broke after 4 months. Koss is good quality; I hope to enjoy these for a long time!"

"Hey all, I am a professional drummer who is always looking for quite ways to practice. I currently have an electronic Drum Set that I use to practice with while at home. These head phones work great with it. It cuts out the tapping sounds the sticks make on the rubber pads. I will also wear them an hour at a time and there is never any discomfort.
Bass and treble come through really well and the volume adjustment on the headphones themselves come in handy when I need that extra boost of volume.
The only downside is the cord, its coiled but it can stretch out. Its not really an issue, I'm just not a fan of coiled wires."
