The Good The Monster iSport Immersion In-Ear Headphones offer a very secure fit and impressive sound, as well as a sweatproof design and flat, tangle-resident cord. They also have an integrated iPhone-friendly ControlTalk inline remote with volume controls, and come with a nice carrying pouch.
The Bad For some people, these earphones' noise isolation may shut out too much of the outside world. Also, if you can't get a tight seal, bass response won't be as good.
The Bottom Line The iSport Immersion headphones rank among the best wired in-ear sports headphone models out there in terms of fit and sound quality.
Headphones for athletes
In recent years Monster has been known more for its celebrity-endorsed headphones and other products, including a now-defunct partnership with. But Monster has also made a quiet push into the wired sports-headphones market with its iSport line, which is set to expand this fall with a couple of new models.
The model reviewed here, the iSport Immersion In-Ear with ControlTalk, comes in a couple of different colors and flavors, including a higher-priced yellow LiveStrong version and a significantly more expensive limited-edition USA model that Monster released around the time of the 2012 Summer Olympics.
I tested both the standard $99 blue-colored iSport (it also comes in black) as well as the USA model ($199). Both rank among the best wired sports headphones I've tested, with the USA model offering a slightly superior fit and slightly better sound.
