The T20 and T20i are the first in-ear headphones to feature RHA’s proprietary DualCoil™ driver technology, engineered to produce levels of resolution, clarity and detail beyond the conventional driver.
The new driver technology features two independently powered voice coils situated in concentric formation around an annular magnet. The voice coils collaborate to manipulate a specially engineered diaphragm, with the outer coil responsible for generating upper midtone and treble frequencies, while the inner coil creates lower mids and bass tones.
The result of this innovative driver technology is an ultra-efficient performance headphone capable of delivering refined, high resolution audio. The T20 and T20i carry Hi-Res Audio certification, conforming to the standards defined by the prestigious Japan Audio Society.
The new T20i features a three-button remote and microphone for use with compatible Apple devices, offering full call, track and volume control with most iPad, iPod and iPhone models.
Other features include metal injection moulded (MIM) stainless steel housings, tuning filter system and a multicore, 1.35m, oxygen-free copper cable featuring patent pending mouldable over-ear hooks. Accessories include a premium carry case and ten pairs of silicone and memory foam ear tips in multiple shapes and sizes with holder. The headphone carries a three year international manufacturer's warranty.
