Fully Wireless & Waterproof

Ready for all your workout and travel needs, the TFZ X1 IEM boasts Bluetooth 5.0 lossless transmission and an IPX7 waterproof rating. It doesn’t skimp on sound, either: each channel features a balanced armature driver, a rarity among fully wireless IEMs. The smooth, glossy housing is lightweight at just 4.6 grams per side, and the built-in battery gives you up to 7 hours of playback or call time. It’s no surprise this IEM comes from TFZ: a company that’s gained a reputation on Massdrop for offering stylish products at an attractive price.
