We at Head-Fi are no strangers to 1MORE, having covered both their E1001 Triple Driver and iBFree wireless IEMs in our buying guide. It's clear the community enjoys them as well because every month we see more and more reviewers talking about 1MORE's products. Today 1MORE announced their newest product, the Quad Driver In-Ear headphone. 1MORE says that the Quad Driver's housing was styled after a jet engine, but mercifully the sound doesn't appear to follow suit. Inside the slipstream body we find a diamond-like carbon dynamic driver and three balanced armatures, each dedicated to their own independent frequencies. As the icing on the cake, the Quad Driver - like its siblings - was tuned by the Grammy Winning sound engineer Luca Bignardi. "1MORE believes there should be nothing between you and your music – with the Quad Driver our goal of having our technology disappear leaving nothing between you and your music - is realized." They'll be available at the end of January for $199 USD. For more information be sure to check out the official press release here.
