I’m loving these so far. I was in the market for a great set of in-ear headphones and extensive research suggests these are really tough to beat. I got mine for $50 on eBay but their normal price is $79.
I’m no audiophile but the sound is phenomenal and it’s amazing the difference between my old Apple earbuds and pretty much any other in-ear drivers I’ve ever tried.
1More does make a Quad Driver, but the reviews, especially on www.rtings.com, don’t make it seem that the extra cost justifies the extra driver.
