Music professionals know well designed earphones shouldn’t compete with outside noises. High listening volumes not only distort sound, they’re not healthy. A superior seal to block out ambient sound is critical. Once that’s achieved, only the highest definition micro-speakers will do. BackBeat Pro earphones deliver both. Super flexible SnugFit™ neoprene ear tips, plus dual flange technology, conform to your ear for superior noise isolation. The balanced armature speakers – essentially full-range miniaturized speakers with built-in amplifiers – are professionally tuned for musician-grade sound. The result is true high-definition, ultra-low distortion audio that rivals recording studio reference speakers. Carry case and eight-piece fit kit included.
