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.

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.

THESE ARE GREAT HEADPHONES. GREAT ISOLATION AND TONAL QUALITY. ALSO A GREAT VALUE.

My husband and I just got new headphones for our stereo, and now when we listen to our cassettes and CDs, they sound so clear! This is the best thing we ever bought, and I'm so glad we got it from O.

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!

I really should have returned these, but I am just too lazy. They feel too heavy on my head and I want to take them off after several minutes. They look great. But if you love bass like I do, forget it.

These headphones have great sound. They have a switch for stereo or mono so the sound is premiere for both music and just voice. The volume control on the side of the headphone is very useful when you need to here someone talk to you or to control when you are not in a loud situation like mowing. I am truley satisfied with everything about these headphones.

Product came exactly as described. Work well, maybe a little larger than you might think, but definately get the job done.

These headphones are heavy and bulky. You can't rest them on your neck when you need to take them off for a short period; they're too big to do this. That may not be a problem for everyone, but I work with headphones on and need to remove them often for just a second. The sound quality is good, as well as the noise canceling aspect. They are not adjustable. My head is average sized and I get a slight headache when using these. Hopefully I can break them in and they'll loosen up a little.

I bought these headphones for a recent trip to Japan. It was the best decision I ever made. Although they aren't the quality of Bose, they're great for the price. Good sound and excellent noise cancellation really helped me out. I would suggest these for travel or for real music lovers who don't want any distractions.

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!

Good external noise rejection and good audio. A little heavy but comfortable.

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 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.

Great headphones. My only complaint is that the volume doesn't quite get quite loud enough to satisfy my loudest mood.

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.

The quality of the sound is remarkably good., but The apparatus itself is very heavy

Great product at a fair price. On time delivery. Recommend this seller.

They are nice but a little on the heavy side. But overall happy with them.
