Born for precise monitoring, offering studio-grade detail and excellent sound isolation in professional closed-back headphones
The Sennheiser HD 300 PRO is a **professional closed-back monitoring headphone** from Sennheiser, featuring a closed, circumaural ear cup design, a maximum sound pressure level of up to 123dB, and excellent ambient noise attenuation.
