ThieAudio Legacy 5

Sold out

Tuned for serious listening, the ThieAudio Legacy 5 offers a boosted bass and sub-bass, which transitions smoothly into a clear, crisp, and accurate mid-range response.

There is a bit less representation of treble at the upper end when contrasted against the rest of the frequency response. 

However, the treble does not sound blunted or weak, but the boosted bass response makes these IEMs sound more prominent in the lows and mids than in the higher harmonics.

Well suited for long-duration listening, the Legacy 5 offers a clean, warm, and inviting soundscape with a thick and satisfying bass response.
