1MORE Quad Driver In-Ear Headphones

The 1MORE Quad Driver In-Ear Headphones are the original THX® Certified Headphones. The diamond-like carbon dynamic driver and 3 balanced armatures deliver unsurpassed dynamic power and definition. It's the equivalent to having 4 speakers in each ear, exclusively dedicated to silky highs, detailed mids, or deep bass.

The streamlined aluminum sound chamber ensures exceptional comfort and noise isolation, while conveniently located in-line controls allow you to effortlessly change volume, skip songs, and make crystal clear calls with the MEMS microphone. The built-in chip even automatically identifies your device's operating system, optimizing the controls for best use.

These headphones are meant to go with you anywhere. They included 9 sizes of ear tips, an airline adapter, a shirt clip, a carrying case, a cord made with oxygen-free copper wire, a Kevlar® core, and a braided sheath for extreme durability and freedom from tangles.

Each pair of 1MORE headphones is also custom-tuned to perfection by Grammy winning sound engineer Luca Bignardi, for a fully balanced and ultra-realistic soundstage.
