Summary: These earbuds are good only if you're looking for headphones that specialize in one thing, and one thing only: Noise-cancellation. Beyond that, there's not much here. It's definitely not on the "better than my high price range gear" level. If you listen to music frequently then these headphones are NOT for you. Although they do have clear mids and highs, the lows are extremely lacking. In-fact, the bass sound is almost non-existent!
Summary: PROS: Excellent sound I like the fact that it has a neck chain (the right earbud has a longer cord that goes around the back of your neck CONS: Noise cancellation doesn't seem to make any difference at all for me. I put on a using speakers and then put these earbuds in. Playing around with the ON/OFF, the only difference I note is it sounds a bit faded, but other than that, no noticeable cancellation. With these on, it kind of feels like you are very deep underwater.
Summary: Sony prétend à une "Réduction du bruit ambiant" "Jusqu'à 87 %" : c'est n'importe quoi. Je l'ai essayé dans plusieurs contextes. La différence avec le réducteur de bruit en position "on" ou "off" est INFIME. En revanche, les oreillettes sont bien isolantes.
