a great choice for those who can’t afford to spend a extra on the company’s more expensive earphones. However, they lack the lighter, more refined touch of expensive earphones. For true critical listening on a budget, though, you can’t do much better. But while the isolation is class-leading and the separation on offer is superb too, the Etymotic MK5 sound can become a little tiring with some types of music.

the Etymotic MK5 Isolator is an extraordinarily good headphone for buyers who prize neutral sound over treble sizzle and plentiful bass. Then add these headphones' class leading sound isolation and affordable price and the MK5 is a tempting buy.
If you’re looking for an affordable and decent sounding pair of earbuds that can really provide solid noise isolation against loud commuter noise then I’d say the mk5 is clearly the best choice. I’m glad this kind of product exists for less than $100 and I have a pair myself that I’ll use for things like plane rides. That said, I wouldn’t say they’re the best sounding earbuds at their price-point, so if isolation isn’t a priority for you I’d recommend considering competitors. The deep in-ear fit might also be bothersome for some people and does take a little getting used to.
