Do u guys have any suggestion about its Impedance?
Do you relaly think it is 30 Ohm as according to Philips?
I ask that, beause my DT 990 Pro 250 Ohm need less power to drive comparing them...
my Xperia Z utra could get DT 990 Pros lot louder
Philips X1 ist very quiet with my phone
and My Creative soundcard with "integrated amp 600 ohm" gets 250 ohm Beyer also lot louder then philips
whats wrong there?
I get my Fiio E12 next days and would try with it
i suppose X1 will sound lot ...loot better with E12
But how the hell to understand that...
I think Beyer Gives worst case Impedance as Data and Philips gives just its best case
Impedance should be depended on Signal frequency and according to mesuring moment freq , you could get different values
AFAIK...and awaiting for comments from guys who know more...
p.s. according to comparison and lil calculations philips should be somewhere 300-350 Ohm Impedance
I also tested its Cable
power input is also a factor. X1 has a maximum capacity of 500mW even though it's rated @ 30ohms. while DT990 which I happened to own before has a capacity of 100mW @ 250/80/600 ohms. tbh my AKG Q701 is much harder to drive with just a 45 ohms but requires 200mW power input. even though. I would pick the Q's over the DT's any day.
