The IE 900 — goodbye to tradeoffs
The IE 900 reveals the true potential of any recording. If it’s a masterpiece, you’ll hear it. Brilliant, sparkling treble — with no trace of sibilance.
A new level of clarity
A single dynamic driver only — of the highest quality, of course.
An acoustic back-volume establishes balance
To ensure accuracy across this critical frequency band, we’ve employed what is known as an acoustic back volume.
The sound of manufacturing expertise
We build the IE 900 at our state-of-the-art audiophile manufacturing plant in Ireland.
A precise fit for precise sound
We took the comfort and secure fit of these professional solutions as inspiration for the IE 900.
It pays to have good connections
In addition to outstanding sound, audiophiles appreciate durable products that are made to last. Here as well, the IE 900 excels.
