Excellent does the job

Bought for someone with tinnitus and they work really well at cancelling traffic noise.

Good product and service

Bought these headphones (NC-40) as they were a good price and active noise cancelling. They work really well in a fairly loud office, giving some peace and quiet to concentrate :)
