"Noise cancelling is good"4.0 starson by JKJacksonMD
Pros: They are small, light and cancel noise
Cons: Don't lose an earbud, replacements are expensive
Summary: I found these to be effective at noise cancellation. I was quite satisfied in that effect. However, my ear buds tended to slip off rather easily. When I lost one, I found that you could replace them at $6.50 for EACH EARBUD (not a pair of replacements but EACH). Let me tell you, I am very careful now when I put them in my jacket pocket. Maybe I'm being a tightwad, but, I would think that after spending $150.00 for earphones, they should feel less inclined to shaft you for the replacement parts that, at least for me, fell off so easily.
Outside of this problem, I have been very satisfied. The sound is clear and I am quite satisfied with the range of sound.
