Paid £19.50 with free postage. I use them with an iPod Nano.
Good: Excellent sound on the move at an entry-level price. Comfy ear pads. Robust, low-tangle cable. Bad: Head band hinge digs into scalp. Fairly flimsy. Noise reduction is a gimmick – expected at the price.
Sound Quality: Bass 8/10, Mid 3/10, Treble 7/10. The bass has rolling clout rather than punch but is not boomy and overpowering. Good for electronic music so good for me. I also own a pair of similarly priced Sennheiser HD202’s. An audiophile might tell you that the 202’s are a better balanced unit but for listening on a train or plane the NC150’s are able to deliver more of the sounds I like.
Comfort: The over ear cups are very comfortable; I can wear them for at least 2 hours without aching lugs. The only major gripe I have with the product is that the hinge on the head band digs into my balding nut. This can be fixed with a hat, probably with good hair too.
Build Quality: They feel flimsy. Cheap plastics on the head band and hinges, the focus must have been on sound quality rather than build. I’m going to buy a carry case (£6.99) because if I don’t they’ll probably get damaged in transit. If a hard case had been included at a higher price it would have made an excellent package. The included imitation leather carry pouch is a good to keep everything tied together but won’t stop them getting crushed in a bag. The cable quality is very good and it doesn’t tangle easily.
Noise Cancelling: Uses one AAA battery. The description on the box says ‘Ultra effective active noise reduction technology filters out external noise to improve audio quality’. They must have a different understanding of ultra effective than me. The effect is minimal, the sound of keyboard typing is successfully suppressed but a knock on a door only has the edge taken off it. I’m inclined to believe that the mechanism works more like a loudness button found on an old hi-fi. When the noise cancelling is turned off bass and treble are simply reduced so noise cancellation is essentially achieved by making the music louder. Ultimately I don’t care because I didn’t buy them for this function, but it is clear that there is less electronic noise reduction than the mechanical effect of the closed-cup design. A gimmick I’d say.
