Summary: Terrible build quality by AKG. Had the upper version of these the 495nc...twice. The headband is very easily broken. Just sent my second pair back to Crutchfield. Sound quality is good and noise canceling is ok, nothing great.
Summary: I tried a few different sets of headphones before settling on these for the overall range of sound - not too much bass but a robust sound overall. I was very happy with them at first, the noise cancelling was a god send on the morning and evening train commute and was very effective in to office...
Summary: These are the first noise-cancelling headphones I have ever used. I bought them to listen to my ipod when commute/walk to work, I like their small size and got them on sale. My walk happens to be on very busy roads with lots of traffic.
Summary: It was my first experience using a noise cancelling headset, therefore might have unrealistic expectations ... but it is good to know that this headphone is doing a great job on low frequencies like airplane noise, not good with high ones.
Summary: The sound when playing music is excellent. Totally excellent. I am an audiophile and trained classical musician. It's also great with house, tecno, Hip Hop as the bass is excellent. They are comfortable too. It's great that they work when the battery's empty, or without a cable.
Summary: I read numerous reviews before buying, and now I've owned the K490 for several months, I wonder if the 'expert' reviewers actually tested this kit in all 'noisy' scenarios. As a regular traveller I needed good noise cancelling headphones, and initially the AKG K490 did the job.
Pros: usb charging , function when not charged , integrated battery in headphones , nc is good when it works
Cons: hear external noise when nc is activated , headphones can get uncomfortable , not the most durable kit , maybe a design fault in headphone drivers?
Summary: I truly love the sound of these, I used them for my daily commute. The noise cancellation works well but I felt it could be further improved, they let in more external noises (like train doors shutting noise) more than i would have anticipated.
Summary: The noise canceling is impressive. The sound quality average,better quality sound can be had by cheaper headphones, but not noise canceling ones. On closer inspection I noticed that the joint where the headphone attaches to the headband, making it able to swivel 90 degrees, looks quite weak and will...
Summary: I really miss an in-line microphone option, so no calls with these; a big omission. If you think noise cancellation is like the Bose in store demo, think again. I bought years ago some Sony in ear NC headphones and hoped the tech had moved on, the white noise has gone but the dynamic cancellation of...
