Noise isolating earbuds are far more effective at blocking out ambient and active noise around a listener due to the way in which they block the sound.

Unlike noise cancelling earbuds or headphones which use electronic means to effectively cancel the undesired noise, sound isolating earbuds block the sound by making a tight seal in the ear canal and not allowing undesired noise to reach the eardrum.  Depending on the brand and quality of the earbud noise isolating models will almost always come with three or more different replacable ear tips to allow the user to select the size that is best for their particular ear canal.  For a more detailed despcription of the difference between noise isolating earbuds and noise cancelling earbuds visit a very informative article on the subject by the electronics manufacturer Shure.
