how about comfort for long time listening? (will ur neck become tired because of the weight of the headphone? joking...)

but, that's very important point..

HD650 + HD595 + Headroom Max Amp owner here..

not bad for sennheiser quality headphone

but for me i still prefer audio technica or grado..

no offense ya
*
u prefer sound signature of grado and audio technica cans?
can u briefly compare sound signature of both senn and audio technica?
thx..
( sorry, a noob question )

y dun u jz add a headamp?
it's cheaper and it gonna boost up ur HD595 performance..
HD595 gonna need a headamp to be really really shine..

This is where ur wrong, even a basic CMOY does something, but minimalist style, u get higher the amp chain u get exponential upgrade to the 595 SQ. test n tried with various amps, and un-amped with various sources.

IMHO, better amp first, then get a new headphone, cos witout an amp (note to oneself, not all headfons or all sources need an amp) u wont see exactly how ur headphone performs. U might get a better sound from ur amp+hedfon compared to say upgrading to a hd650 without an amp <-- tis u can ask around, but most lurkers here in lowyat jus dun care to comment, but they know.

However, HD595, get a high current amp. u wont benefit na~da from unbuffered opamp to make u say ooooh-aaahhh.

thx for the input biggrin.gif

may i know y must get a high current amp? because of the high impedence so the amp can drive the hp easily?

my 555 can be drove easily without amp, however, i do think that there is still room for improvement fot this hp..
do u mean that 555 suites better with an high current amp as well?

so far i am very satisfy with the hp.. love the sound although it is still in burn in process.. however, my ears do feel fatigue quite fast, about half an hour of listening.. i dunno y.. mayb my ears cant stand in closed place without sufficient air supply.. haha..

i took half an hour to digest ur post, do a little maths and ohm''s law, still got a little blurry.. nvm.. it takes time to digest..

i am planning to get LD2+, and the worst thing is i am not very good with the specs:

Frenquency response: 10HZ to 35KHZ (-3db)
Distortion: <=1% (50mW, 300ohm)
<=3% (92mW, 300 ohm)
Power handling capacity: 35W (under alternating current situation)
Output terminal: 6.5mm Mic Jack
Input terminal: RCA Jack
Can drive headphones with 30 ohm to 600 ohm

i dont see any statement that shows high or low current, mayb u can teach me how to do the maths a little there.. ( i dunno how i calculate, but looks like i got 31mA running for 50ohm, correct me pls.. )

will it be a wise choice then?

V=IR
P=I^2 * R or P= V^2 / R
I^2=P/R
I^2=0.05/300
I=sqrt(0.05/300) = 0.013A (13mA)

Vrms=0.013*300=3.9

The THD is <=1% when the amp is driving a 300ohm phone (say a sennheiser) at 3.9Vrms.



I^2=P/R
I^2=0.092/300
I=sqrt(0.092/300) = 0.018A (18mA)

Vrms=0.018*300=5.4

The THD is <=3% when the amp is driving a 300ohm phone at 5.4Vrms.

How loud is 3.9Vrms or 5.4Vrms? take a test tone generator and play a 1khz freq @ 0db. Take your multimeter and take the measuremet at that volume then plug in ur headphone and give it a try.
let's say you are listening to a volume of 6Vrms with your 555, your headphone is sucking up:
V/R=I
6/50=0.12A (120mA)
P=0.12^2 * 50 =0.72W (720mW)

50mW, THD <=1%
92mW, THD  <=3%
120mW, THD <= rolleyes.gif

*
if the amp is driving 50ohm senn,
it sucks up 31mA ( 3 times the 300ohm does )
and Vrms = 1.55 Vrms

so, the THD is <= 1% when the amp is driving a 50ohm at 1.55 Vrms?
in other words, the THD for driving 50 ohm phone is quite high although it's in low volume, right?

btw, amps are rated by their power handling capabilities. Current and voltage are components of power. You should already understand by now how much current/voltage a headphone would need by now, and whether the amp could "drive" them.

gonna give ld2+ a try after this, else, gonna look for other choice..
thx a lot.. rclxms.gif

hi there.. i'm using hd555, well the main problem i'm facing is the comfort issue.. it's due to the sponge is too thin.. can i replace it with other sponge?

i heard that senn does provides replacement sponge for some models, which 1 will suits hd555 in term of size with more comfort? any recommendation?

thx..

u can search about EMU0404 or EMu1212 at creative website there. it;s under professional soundcard.

1 thing for sure, 0404 is gonna cost more than 200..

good luck, good hunt

Finally there's someone offering his big help to me.  biggrin.gif  rclxms.gif  What I had in my mind are HD650, 600, 595, AKG701, Beyer DT880, Grado SR325i (or higher grados) but I really don't know what should I choose as I never audition them and I don't know what "kind" of person I am, read a lot reviews but too much will make me more confuse  rclxub.gif  rclxub.gif  rclxub.gif . Up to date I only know mediaplex in KLCC and Music by design at Jalan Tun Razak (which two places are quite near...) selling sennheiser and Grado respectively, but I don't know whether they are they letting you to audition them.
Well, the senn's stocks I could get from Davis later on (if cheaper  biggrin.gif ).
For amp, I already possess Little Dot Micro+. I know it would sooner or later not enough to power them but anyhow just get the phones first (as adviced by Alamaklor).  tongue.gif
*
IMHO,little dot micro is not powerful enough to drive those high end headphone.. even those senn are easily driven phones, but little dot micro is not good enough to bring out the full potential..

i would suggest that u take senn as it's easily driven and the warm sounding phone is more acceptable for most of people.. unless u like bright/up front sound then u should go for grado..

What do u mean by noisy btw?

mayb he 'heavy' he meant was referring to heavier/deeper bass impact?

@sonyman
btw, mind to explain the noisy u mentioned too? rclxub.gif
