Audeze LLC. (Odyssey) made remarkable advance in 2015 by introducing a Lightning-connected pair, called the EL- 8 , which integrates an amp and a digital-to-analog converter into the cable. This makes it possible to get the best and loudest sound from a pair of true audiophile headphones while relying on just an iPhone as the music source
The EL-8 has been made beautifully. A thin ribbon headband has a spring-loaded pad at the top of its curve, and they hug the head comfortably with a nice amount of clamp. The metal ear cups are ringed with wood veneer and capped with high-quality leather pads. Inside are the 100mm planar magnetic drivers—if you have the open-backs, the slots in the cups provide a nice visual
EL-8 has been considered as one of the best audio peripheral available currently in the world.
