  The SMH-500 Professional Studio Headphones from Senal feature accurate sound, superior comfort, and durable materials. They are designed for studio and light field applications. The over-ear, closed-back design provides ample isolation to block out ambient noise on location, and prevent headphone leakage when recording in the studio. Their soft, replaceable ear cushions, lightweight design and refined sound ensure a comfortable listening experience, even during extended sessions.
  
  Equipped with 40mm neodymium drivers at 58 ohm impedance, the SMH-500 headphones are designed to be loud enough when attached to low-powered devices such as mobile phones and mp3 players, yet robust enough to handle studio headphone amps without distortion.
  
  The headphones are designed with an EQ curve that's been tailored for an enhanced low end that allows engineers to detect rumble and monitor bass frequencies effectively. The excellent high-frequency response has been enhanced to accurately and clearly reproduce spatial detail. There is also a slight bump in the midrange to maintain focus on vocal and dialogue intelligibility.
  
  In addition to great sound, the SMH-500 headphones offer superior comfort with a soft padded headband. The 10' single-sided coiled cable allows freedom of movement for musicians, editors, and engineers.
  
  Whether monitoring in the field, studio or on a portable device, the SMH-500 headphones provide an accurate and comfortable listening experience. UPC: 847628569447
