It depends on the size and shape of head, the bumps don't annoy me unless i'm wearing them for more than 2 albums worth of time.

They are just completely different sounding, get both & be doubly happy

Quote: I think I can help, I have the same equipment as you so its nice to speak to a fellow NJC Audio owner (I thought I was all alone here, it seems most owners keep quiet as its like the best kept secret in the audio world, shhhh!), I also use the NJC Monitor II amp with their...

NJC Audio Monitor II headphone amp & 24 bit reference DAC in depth review   Disclaimer, there is a lot of text below since everytime I thought of something else or something I found really good I added it to my small review which grew & grew, but it seemed a shame to trim it down & it's also...

I thought they sounded ok with the Burson amp, but I could not listen to them for more than an hour without becoming fatigued, I would like to try them again on my new gear but I have so many other headphones I want first

Ah so that's what that is, thanks.   Hope you find what you are looking for, I am starting to believe that the HD650's really want more & more power, I thought they were good on the Burson but better on the latest amp I have which has something like 6 watts output, so look for an amp that...

I just noticed this thread, while i'm not new to the HD650's as I used to have a pair a while ago I have since got another pair & with a whole lot of new gear to go with them.   I think the HD650's are one hell of a headphone once you get the right amp, I can listen to them for hours & hours...

Another headphone amp that has the kind of power you are looking for without having to resort to some kind of speaker amp or reciever is the headphone amp I use, the maker is called NJC Audio & the actual amp is called a monitor II, its a solid state type amp which is hand made in the UK, i'm...

Quote:   Thats a new one on me, whats the speed ball upgrade?   I love the HD650's & if you can get a good amp for them you will see why they are highly regarded by lots of people.

I am now getting back into the HiFi world after having to sell all my equipment for financial reasons which I will spare you the boring details, but here is my story on my quest to rebuild my entire system from scratch.   Just in case you are interested my original system consisted of the...

I have the HD650 too, some people use them on sound cards & ipods, but I have found like many they sound best when you give them a proper amping, but that costs money.

Quote: The Beyerdynamic DT100 have a detachable cable, ive heard of people using these for drumming in the past.  

I think your right, the human ear can be better than any measuring equipment, but I think it can also be led by the brain, thinking of differences that arnt actually there, your brain can be a powerful thing, are you really hearing a difference or thinking you are.

Yes some great information & opinions so far

Quote: Yes for the price they cost it would have been nice having a mini XLR or similar, of course we could retro fit something but who in their right mind wants to mess around with a brand new pair of T1's, thats something you would do on a pair of HD201's, not headphones of this...

Enjoy them.

Thats the trouble with discounts based on "retail" pricing, the suggested retail price is usually far higher than any street price.

I can almost feel your excitement from over here

Quote: When I listened to the Beyer DT880 & T1's I got the same impression, as if the T1 was merely a better DT880, worth the extra price though? well not quite sure, probably not.  

Couldnt agree more with the above post, im ashamed to say I happen to be one of those "picky" types that strive to get that extra 1%

I personally wouldnt pay much for the 598's but thats because I am not that fond of them, but if you can get them cheap enough they certainly would have no problems with comfort, I wear glasses & they were fine when I tried them, for gaming they would be more than enough.

Is it really? wow it looks so lifelike.

Quote: Yes & not to forget the good ole Beyer velour

Also take a look at the Audio Technica ATH-AD700 headphones, those are a gamers choice from what I hear, I had the chance to try them recently & while they are no match for better headphones they are good for the price & comfort is top notch.

Have you also considered anything from Beyerdynamic rather than the Sennheiser ones listed? something perhaps like the Beyer DT770 as a lot of people use those with a PC, they have velour pads & are quite comfortable, or perhaps the Denon D2000 or the model below that if those are out of budget...
