Summary: The noise isolation is great! You can barely hear anything else when the headphones are on. I was a tad disappointed with the sound of the bass. Usually, noise canceling/isolating headphones have great sound and bass. The sound from these headphones is pretty average, but not bad. I use these headphones every day for about 2-3 hours, so I'm very pleased with their durability. I'm happy with this purchase.
Summary: I like rich deep bass and this didn't have it. My stock Sony mp3 headphones were way better. When I pulled the rubber earpiece (to change them) the speaker came with it. The slider on the volume control did not slide smoothly. Go ahead and pay more for the better ones is my advice.
Summary: Since my local Walmart doesn't seem to be carrying this product anymore, I tried a different one but was sadly disappointed. So I ordered this one online and it was sent to my local Walmart with no charge for shipping. It is just what I wanted and I love it. It cuts out static and other noise on my radio and is very comfortable in my ears.
Summary: Most ear-bud type headphones don't work well for me, as they often fall out and are sometimes irritating. I already a couple pair of over-the-ear models, but they aren't as practical for work. The sound quality of these is also extremely good, which is what I've always gotten from this brand. In addition, the Koss brand has always appealed to me because of their lifetime warranty, which they've always made good on....
Summary: I really like this product. It helps cancel out noise, is pretty loud, and doesn't hurt my ears. The only things I don't like are the volume control and shorting out in the cord. The volume control is obtrusive, and the cord tends to short out after awhile.
Pros: Fantastic sound, great bass, almost noise-cancelling
Summary: I was hoping for something of a better quality having owned Koss products before. While these are not terrible earbuds, they certainly did not live up to my expectations. My biggest complaint is that the bass is a little too heavy and quite muddy. I regret purchasing these.
