Revolutionary driver technology

High-Resolution DualCoil™ Dynamic Driver

The T20i features the revolutionary DualCoil™ driver, a reimagined dynamic driver engineered to offer high-resolution sound reproduction. DualCoil™ technology features two independent voice coils, each responsible for producing part of the frequency range for refined, high-resolution audio.

Customisable sound signature

RHA's T20i features a choice of three pairs of tuning filters for sound signature customisation. Bass filters emphasise low frequencies for genres such as rock, hip-hop and EDM, while treble filters bring out upper frequency detail in classical, acoustic or jazz tracks. The silver reference filters offer neutral, balanced sound reproduction.

  • Bass (Effective max +3dB below 200Hz)

Made in metal

Injection moulded stainless steel construction

The T20i's ergonomic driver housings are constructed using the metal injection moulding process. By using this advanced manufacturing technique for the headphone's housing, RHA's T Series products combine the durability of stainless steel with a natural, contoured shape which sits comfortably in the ear.

Take control

3-button remote and microphone

An in-line remote and microphone offer convenient control over calls, music and volume with compatible Apple® devices including iPad, iPod and iPhone models. The remote is found on an oxygen-free copper cable finished with a high durability outer which offers minimal tangling.

Perfect fit

Patent pending, mouldable over-ear hooks

The T20i features unique, patent pending over-ear hooks designed to hold the headphones in position with the cable running over and behind the ear. The over-ear hooks are fully mouldable, ensuring the headphone offers a comfortable, secure fit and effective noise isolation.

"A great example of harnessing engineering and materials with a purpose."
