The IE-20 XB professional reference earphones use the same revolutionary Ultimate Ears technology trusted by top touring artists and their sound engineers - and feature enhanced bass designed for music that is normally monitored on systems with a subwoofer. The IE-20 XB benefits from a dual-speaker design with integral crossover: The dynamic low-frequency driver delivers full, punchy bass while the precision-balanced armature driver provides crystal-clear mid-range and high frequencies. This results in a high-performance reference monitor system designed for critical listening during mobile recording/production of bass-enhanced music such as dance and urban genres - not to mention transforming the way your personal music/DVD/game player sounds. Other features include 16dB of isolation, professional over-ear loops, detachable/replaceable cable and universal fit kit. Simply put, you won't find a finer set of earphones for delivering the bass you love.
