When it comes to the 1MORE Quad Driver, there's a lot to like. These are truly excellent IEMs, crafted with exceptional attention to details and beautifully tuned acoustically. They are by no means cheap - $200 can get you all sorts of great traditional over-ear headphones - but 1MORE went out of their way to make sure you forget their cost. Just look at the way they're packaged and the sheer number of accessories that are included in the box. You get everything from a clothes clip and an in-flight entertainment system adapter to a sturdy carrying box and a grand total of nine different ear tips. They need a great seal for maximum performance, and said number of ear tips will definitely enable you to find a pair with just such a fit.

Nevermind the bundle, anyone can pack a lot of stuff into the box. Let's talk about the build quality. 1MORE went with an all-metal construction for both the headphones and the in-line remote control and a Kevlar-coated cable. Thanks to that, the Quad Driver looks and feels luxurious, as if it cost even more than it does. Someone also obviously took exceptional care not to go overboard with the design, which is why these IEMs will suit you perfectly regardless of what your daily outfit consists of.

Finally, there's the most important aspect - the sound quality. These are honestly the best IEMs I listened to this year and a definite reference for the $200 price bracket. Their acoustic presentation is best described as rich, lively, and exciting. No matter what genre of music you prefer, the 1MORE Quad Driver will offer you endless hours of joy. The built-in microphone, affixed to the in-line remote, sounds surprisingly good as well, so you won't have to take these off when you want to answer a phone call.

The only "problem" with these, if I can even call it a problem, is that 1MORE's very own $100 Triple Driver offers much of the same for half the price. If sound quality is the only thing you're interested in, you should know that the Quad Driver doesn't sound twice as good as the Triple Driver. It does, however, offer some audible improvements across the frequency spectrum and sports a better, more luxurious build quality. To put it simply, even though the Triple Driver has a better price-performance ratio, the Quad Driver is the better of the two. I wholeheartedly recommend it.
