The sound is great, but should have included a foam cover for the mouthpiece for clearer recordings. So, I decided to purchase a second pair, but unfortunately noticed that the K490nc model was no longer available. I highly recommend these and promise to update later say a month from now and see how they’re holding up, but construction is done nicely and although I don’t think it matters they take pride in your packaging, which gives you a feeling of a more luxurious product. Then I switched to the Sennheiser. I guess Ill figure out what to do with this, but I found some very strong peg racks in gold at Target. This right shoe became unattached far more quickly than the right one and just last night I heard a muffled pop sound, only to find that the entire front of the sole on the right shoe has separated nearly two inches back from the toe of the shoe! Moral. I expected the noise canceling to be much better although it is good you still here quite a bit of ambient noise. From a person that has spent a lot of money on other types of earphones with little satisfaction, I can honestly say these are the best I have had so far. However, it was raining and package was soaking wet.
