The MasterPulse Over-ear headset conveniently delivers high-quality sound in two distinct modes. It’s a headset that allows you to tailor your own listening experience, whether you’re gaming, traveling, or gaming while traveling. Imagine Bass FX as an easy-to-use voice changer for your ears. When the side panels are removed, sound opens up and the quality of lower frequencies is significantly enhanced. This can be seen, or heard, through the noticeably enriched bass tones. When the side panels are on, the MasterPulse will provide you with crystal clear and balanced sound.
