The amazing sound quality to the previous speakers have already omitted accurate detail. This opinion I can join without restriction. A lack I yet discovered: One should sit as still as possible if you want to enjoy music with the SONY XBA4, jogging this part is only conditionally suitable. Rub the cables when moving to clothing, the transfers to the earplugs, which leads to unpleasant noise. This circumstance has struck me in any of my previous in-ear headphones (Bose, Sennheiser, Koss) so blatant.
