The Good: The terrific-sounding 1More Triple Driver is attractively designed, with nicely finished aluminum ear pieces and a Kevlar-reinforced cable. It has a three-button inline remote and microphone that's compatible with both Android and iOS devices, comes with a variety of eartips, and includes a nice carrying case. The Bad: You can lose the tight seal if you're walking around (not the best headphone for more active users). The Bottom Line: The 1More Triple Driver is a great-sounding in-ear headphone for its relatively modest price point. You probably haven't heard of 1More, a Chinese company based in Shenzhen, but its Triple-Driver is one of the best sounding in-ear headphones we've heard for $100. It seems well built, with nicely finished aluminum earpieces and a Kevlar-reinforced cable that's designed to limit cord noise when it rubs against your clothing. The headphone comes with a variety of silicon and foam eartips to ensure that you get a tight seal and the inline three-button remote and microphone are compatible with both Android and Apple devices (the volume controls work with both). A hard carrying case is also included. Each earpiece hosts a single dynamic driver, plus two balanced armature drivers -- thus the name Triple Driver. The impedance is listed at 32 ohms. Typically, a 32-ohm headphone would be harder to drive than a more typical 16-ohm headphone, but we didn't have a problem getting ample volume from a smartphone. Clean, rich soundThe Triple-Driver's sound is not only full and warm but nicely detailed. There's plenty of bass oomph and definition is decent enough. The midrange sounds clear and natural; this is a headphone that will appeal to audiophiles.
