TFZ Secret Garden & Secret Garden III IEM

When it comes to high-value IEMs, TFZ has established itself as a serious contender in a variety of price ranges. On the higher end sits the Secret Garden II, the second generation of TFZ's flagship IEM. This model features a 12-millimeter double-magnetic-circuit graphene driver, which aims for a strong bass and midrange, along with a smooth treble and a large soundstage. Shaped like a CIEM, this earphone offers a snug, comfortable fit in the ear. It comes in a few different shell colors, all with an eye-catching silver faceplate, and the 0.78-millimeter two-pin connector makes for easy cable replacement in the future. Also available is the Secret Garden III, detailed below.

Moving up the ladder from the popular Secret Garden II, the TFZ's new Secret Garden 3 showcases several new features. This high-end IEM uses three highly regarded Knowles balanced armature drivers: 30095 for the high frequencies, 29689 for the mid frequencies, and 22955 for the low frequencies. Working together, these bring out more detail and better sound separation than dynamic driver configurations. Another unique feature sets the Secret Garden 3 apart: Inside each housing is an adjustable switch with four settings. Use the switch to adjust the sound to favor high, mid-high, mid-low, or low frequencies.
