Sennheiser is a brand made by audiophiles and for them. That’s why to launch their new line of earphones (IE 300 and IE 900)for this category we changed brand’s strategy. No more models, no more fake bs. Only real audiophiles will be spokespersons for the line of high-fidelity products. We invited three sound aficionados to test and talk about why hi-fi sound is the only sound they accept.
