Hmmm.... so my EHP-O2 amp arrived yesterday and I had a play around it. I initially thought that the 598s being only 50ohms would be easy to drive. But without turning on the gain settings, I had to turn the volume knob to to about 2 oclock to match unamped volume and 3-4 oclock to have a nice amped sound. I was wondering if this was normal. I think the default gain settings for the EHP model are x1 and x5.
 
Any 598 users with O2 amp can shed some light?

That sounds odd. I keep the gain switch turned off at all times (even with HD 600s), and the HD 598 get loud enough with the volume knob sitting at around 10 o'clock. I have the O2 with the ODAC inside (EHP-O2D), and I have noticed that I have to turn the volume knob higher if I plug another source into the amp.

What's your source?

Line out from Xonar DGX
 
I did a comparison of plugging the headphones straight to line out and through the amplifier. The volume definitely only becomes at the same levels when the volume knob is at around 2 o'clock without the gain switch on

Headphones react oddly to different things, and everyone has different hearing. For me, I have cans with 32 ohms impedance and I have them on high gain and 2.75/8 volume on an FiiO E11, and at that point they sound their nicest to me. Just mess around with them, and find the settings you like the most.

Headphone impedance indicates the load the amplifier sees (and must drive). It's sensitivity that determines how loud it will be with 'X' amount of power.

You cannot necessarily predict sensitivity based on impedance.

hi, does anyone one with small head knows if this ok to wear?

 

[BillsonChang007]

It fits fine IMO

Yes, it's ok.

 

[BenXiaoHai]

Ahhh i see... because I read that the 598 should work fine at no gain settings, and I am slightly concerned that I have to turn the volume knob to about 4 o'clock to get good volume.
 
I'm still trying to find a good fit for extended periods of listening to be honest. It is definitely not Audio Technica AD700 comfortable, which was the previous one I had.

It would fit smaller heads better i feel.

Fits like a glove. It's really awkward on larger heads.

Dunno about that. I have a fairly bigger head than most and I feel they're pretty comfortable.

Sorry, it looks awkward, since I have a smaller head I wouldn't know.

Hi,
 
I bought my HD598's a year ago and they were my first good headphones. At first I thought the sound was jaw dropping and it amazed me to no extent..
However  recently they've been sounding dull and making my music sound boring and I could also do with a little more bass for some of the genres I listen to such as jazz
 
Whats a good budget amp(below 200US) for these cans.
 
Thanks!
