Review title: Sony MDR-NC6 Noise Canceling Headphones
Product review: Do not buy these phones for noise cancelling - they are ineffective, both in the passive mode (just phones on your ears) and with the noise cancellation turned on. They are supposed to cancel low frequencies only, which means that all noise of conversations, PA announcements and so on come through as if you had no phones on. In the low frequencies, such as airplane engine noise, they are ineffective as well.I have no opinion on their performance as headphones per se, since I bought them for airplane travel noise cancellation.I was forced by the review form to give this product one star, but in my opinion it is worth zero stars.They also take up quite a bit of room, which these days of restricted carry-on on airplanes, is another disadvantage.
