1More Quad Driver earphones use 4 drivers to achieve their fantastic sound for the money: 1 dynamic driver (round) for bass and three armature drivers (like tiny boxes with reed-like device inside) for the high frequencies, to provide awesome clarity, power and value. 1More are using each type of driver for the frequency range it excels at. The Quad Driver is a 3 way design, with a woofer, 2 tweeters and the 4th driver a super-tweeter.
The housings are aluminum, there are Kevlar core cables for durability and oxygen free copper wire for a high sound quality connection. There is an inline mic and controls, fully functional including volume, with both IOS and Android phones. Nice black, hard shell leather case, 6.5mm adaptor, airplane adaptor and 9 sets of ear tips are included.
People are getting great sound from their phones in store and the curved shape fits a wide variety of people well. *if you have tiny ears, try these on first, otherwise, go for it!
"I choose these earphones because of their amazing comfort and great sound. They handle a variety of music with authority, and when paired with my Oppo HA-2SE they really shine. The all-metal housing feels very premium and durable, and the Kevlar cable is tangle resistant. Also nice that the in-line control has cross-compatibility as I might jump Apple's ship soon. I listen to these Quads for extended periods at work and they never leave my ears feeling fatigued or sore. Excellent comfort! Sound isolation strikes a perfect balance for my use case. They block the white noise of the office, but still allow me to hear the phone ring or someone call my name. Overall, they are terrific IEMs. I also recommend trying the Triple Driver version for even more insane value."
"Very fast shipping to Toronto, and my husband loves this earphone. We even don't need to go to USA to buy it!"
