TH-300X Studio Headphones. TASCAM's TH-300X provides the clear, uncolored sound that musicians demand in the studio, while providing plenty of power handling and isolation for tracking and live use. The closed-back design isolates the musician, preventing microphone bleed and feedback. The plush leatherette ear pads and adjustable headband make the TH-300X comfortable enough for hours of wear. No matter how soft or loud you monitor, the TH-300X can handle plenty of power without distortion. The large-diameter drivers provide plenty of bass response, with treble that's accurate without being harsh for extended recording sessions. The included 1/8"-to-1/4" adapter makes them compatible with consumer or professional gear, and gold-plated connectors won't corrode and crackle after a few years of use.
