British headphone company Reid Heath Audio (RHA) introduced the new T20 in-ear headphones position above the T10i.  T20 is the first in-ear headphone 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 is an ultra-efficient performance driver capable of delivering refined, high resolution audio.

“We’re incredibly excited to bring a brand new technology to the High End show 2015. The T20’s DualCoil™ driver uses micro annular magnets and two voice coils, completely reimagining the conventional dynamic driver to create an in-ear headphone that is able to achieve the highest quality sound reproduction,” said Lewis Heath, Product Director at RHA.

As with the T10i, the T20 features ergonomic, stainless steel housings created using metal injection moulding (MIM) for outstanding durability, comfort and sonic properties. A custom tuning filter system permits sound signature adjustment; in addition to a balanced reference filter, the T20 also includes filters to adjust emphasis on bass or treble frequencies.


Other features include a multicore, 1.35m, oxygen-free copper cable and 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.
