Big Bass, Tight Seal

A solid IEM for bassheads on a budget, the TFZ Series 1 delivers a pleasant, non-fatiguing sound signature with a strong low end. The housing is large enough to accommodate the dual-chamber dynamic driver within, and shaped to fill your outer ear for a secure, comfortable fit and commuter-friendly noise isolation. The 4-foot-long cable ends in a 3.5-millimeter gold-plated plug, and the included accessories—over-ear hooks and ear tips aplenty—allow you to personalize your listening experience.

Note: At checkout, you’ll have your choice of finishes between Army Green, Black, Black Reddish Violet, Carbon Fiber, Gray, Purple, Red, Reddish Violet, White, and Wooden Lubricious.
