Designed from the critically acclaimed ATH-M50x, the ATH-M50xSTS StreamSet is equipped with the same 45 mm large-aperture drivers with the addition of two sets of distinct interchangeable earpads– M50x earpads that stress audio quality and sound isolation and mesh and leatherette to emphasize breathability and comfort. Experience studio-quality articulation and intelligibility thanks to the StreamSet’s cardioid condenser microphone, adopted from the iconic 20 Series studio mics. The microphone’s design places it at the end of a flexible boom arm, keeping the mic in close proximity to your mouth, helping to reject background noise and deliver crystal-clear audio. The microphone can be easily muted quickly and efficiently simply by flipping the boom arm into the up position.
