Headphones Review: JM Audio Editions R9 and Custom Open Backs by GTW Grand Theft World Producers

 

head-fi member review:

"R7DX JM Stealth Edition Mid-Fi Endgame"


"Astonishing Soundstage"

"Incredible control across Frequency Range, Dynamic Bass, Invalidates closed back headphones below $500..."

 "Absolutely blows my other closed back headphones out of the water"


"R7 JM headphone manages it's entire frequency range with an astonishing level of control way above its price bracket."

"Hats off to John Massaria for taking a "low-fi" headphone and elevating it to end game territory. "
