Sennheiser breaking the mould

ETNow.com: Since their official debut at NAMM last year, Sennheiser’s IE 400 PRO and IE 500 PRO in-ear monitors have turned into essential companions and can be found in the pockets of audio lovers and musicians all over the world. They are choosing the single dynamic principle of these in-ears because of their distortion-free, detailed and accurate sound reproduction, as well as their comfortable fit that comes as close as possible to custom ear-moulds. Sennheiser asked four industry professionals to share their thoughts and experience of using in-ear monitors.
