Thieaudio Legacy 4 IEM

Between the budget Legacy 3 and the flagship Legacy 5, Thieaudio’s Legacy 4 IEM gives listeners an attractive middle ground—in terms of both tuning and price tag—with a sound all its own. Driving the Legacy 4 is Thieaudio’s all-new, 8-millimeter poly-membrane dynamic driver for the low ends, a tried-and-true Knowles ED29689 balanced armature for the mids, and a custom Bellsing dual balanced-armature tweeter for the highs. With a less aggressive crossover design than the Legacy 5, the Legacy 4 has a warmer sound while still retaining the smooth trebles of its predecessor. True to their name, the new Bellsing tweeters add airiness and shimmer to the mix, while the new dynamic drivers add definition to the bass frequencies. Tying the design together, an ergonomic shell made of imported German resin provides up to 26 decibels of attenuation, and a 4-core OCC custom cable ensures excellent signal transmission.
