Jul 20, 2008 at 2:07 PM Post #2 of 2
PRO 550
Freq. Resp.: 10Hz - 22kHz, 64 Ohm; DB: 102 dB; Driver: 1.97" Mylar; ULE: 98%

PRO 650
Freq. Resp.: 10Hz - 25kHz, 75 Ohm; DB: 95 dB; Driver: 1.58" Mylar, Gold Plated; ULE: 98%

The 550 has an all-plastic outer ear cup, the 650 has a diamond-cut aluminum plate on the outer ear-cup.

Both come with a hard carrying case, extra ear pads and 2 cables (1 straight, 1 curled).

Hope this helps.
