I have listed a few popular earbud models in the $100 range (some higher, some lower) that are well rated and favorably reviewed. Noise isolating earbuds are a good option if your aim is to block out things like conversation or less constant but nonetheless unwelcome sounds. Noise isolation can also deal with low frequency constant sounds provided the fit of the earbuds in the ear is really good.

The sound quality in this price range is generally better than lower priced earbuds. Still they are not up to par with the reproductive quality of pricier models. If you want really superb sound you need to invest at least a few hundred dollars in a pair of great earbuds (and you could check out Shure E5c Sound Isolating Earphones, Klipsch Custom-3 In-Ear Noise Isolating Earphone, Phiaton PS 200 Sound Isolating Earphones and Shure SCL5-CL Sound Isolating Headphones).

The most important feature of these kind of earbuds is their fit. Most of the models that work well come with numerous types of tips. To find the best fit you generally have to switch out the tips to find the set that works best. It may also be somewhat tricky to get this earbuds into your ear just right. By design, noise isolating earbuds fit deeper into your ear than conventional earbuds. Some people do not like this and simply cannot tolerate wearing them.

Many reviewers, from various websites, report that sound quality of noise isolating earbuds are strongly influenced by fit. A nice fit means can you cannot hear anything when they are in your ears and there is nothing playing through the amplifiers. Without a good fit you can hear more environmental noise and do not get as good a reproduction of the sounds being played.

Finally it should be noted that there are no one-size-fits-all earbud design, so in trying to get a tight fit not everyone will find the perfect match between their ears and every earbud. If you look at reviews realize that there will be some complaints from a few folks that are mad the earbuds would not fit well. This may well mean that these people were simply not compatible with that particular model’s design.

Ultimate Ears has a short video that explains how to use their earbuds video (it should be noted their .Fi5 does not shop with a case like the one shown in the video). This provides some idea about why there is such an emphasis on fitting the earbuds just right to get both the best sound and the optimal noise isolation.
