Yamaha RH5MA headphones are the undisputed professional choice in many studios across the globe.
Like Yamaha's universally accepted NS10M monitor cabinets, think of the RH5M as as a standard reference monitor. They are that good. Their audio performance includes 98dB sensitivity, ultra-low 32 ohm impedance (so you'll never have a problem hearing them) and 20Hz - 20kHz frequency response.
The ultimate in comfort, Yamaha RH5MA headphones have a semi-open design with urethane leather earpads and they weigh less then 6 oz. Their 8 foot oxygen free copper cord has a 1/4" end and includes a 1/8" adapter.
