Title: Sent them back
Review: I tried these and sent them back. For years I've been using Sony in-ear earbuds and got used to the sound quality. The Etymotic ER6 does an ok job at sound isolating but no more than most in-ear ear buds and they have a low sound quality when compared to the others. The frequency response for the Etymotics is 20 Hz to 16 kHz. For the Sony it is 23Hz to 6Hz. This is a big difference in sound quality especially bass. Remember these aren't noise cancelling headphones they are noise isolating. All in-ear ear buds are noise isolating. I also can't figure out why they cost so much more.
Is the review positive or negative?
