So I like a warmish, fuller bodied sound with a bit of impactfuly bass.


The HD650 are my first open headphones. And when listening to them via the DragonFly, I find they sound underwhelming. The sound seems flat compared to the IE80. Detail is there, as I am hearing things on familiar records that I didn't hear before, and I do like the sound, as I am reluctant to take them off when listening. Just that sometimes, the sound isn't very impactful.


I know amps are recommended for the HD650, however, the DragonFly drives the HD650 to a level loud enough for me at the volume at about 45 out of the available 65 steps.


So, will and amp improve the sound? Does the HD650 need the amp to provide good current rather then volume to drive it properly? Or is it just about getting "used" to the sound or a reference type headphone?

Every once in a while I feel like the 650s sound is really "flat". Not in frequency response but sound signature, like "dry" and like vocals are just really bad, recessed pieces. I don't know what causes this, but I need a better amp (eyeing the Lyr for when I can afford it). I'd like to ask the same thing too, well not exactly, but to some extent.

taylor, your ears are not playing tricks on you, Senns have an odd dynamic-flatness to them for my ears as well. Although, Linear might be a more precise word though since flat has neg connotations and for some music genres it's probably heard as a redeaming quality (electronic in particular). It's almost like a sheet of sound whereas a grado style phone is more dynamic in the traditional sense...... The recessed vocals on some recordings may be understood as well. Senns have a wicked midrange 'affectation' that sounds awesome on some material and not so on others. That's the tradeoff of anything that sounds extra-ordinary on some material. When it jives it's great and when it doesn't, it swings just as far in the opp direction........The amp search is unlikely to dramatically fix either of the flaws ime.

Just because it can drive it to unbearably high volumes doesn't necessarily mean it's a good enough amp.  The HD 650s are known to scale well with better amps.  So chances are, a USB thumbstick drawing power from the USB port won't get the juice needed to make these babies sing.  Don't get me wrong... the dragonfly is a very capable amp/DAC... just maybe not enough to drive 300Ohm cans on it's own.

As others may point out, loudness and sound quality aren't the same. I've heard way too many junk car amps which are deafening in both volume and noise.

 

Will an amp improve the sound? Possibly, but I don't know the DragonFly. The HD 650's are an reasonably easy-to-drive load but they tend to be revealing. They don't do much at all to hide or smooth out a bad DAC, amp, or recording. Some people call this "scaling". They'll respond well to a good amplifier.

 

Your concerns may just be breaking in your ears to the '650 sound. But, perhaps they just aren't for you. As popular as they seem to be, they're not for everyone ... but I have no plans to stop listening to mine full-time at home.

Ok I am going to need some guidance here. I know it's probably been covered before but I have a limited time frame to make a decision and I don't want to spend money for no benefit. 

 

I have my HD650's and a Asus Xonar STX Sound Card. I am told it's a good dac/amp. I am trying to decide if I should ante up for a better amp and dac or combo. 

 

Right now I am considering:

 

O2 Amp and Dac

Bottle Crack Amp (Can you buy these assembled?)

Asgard + Bifrost Combo.

 

I listen to mostly pop music from my PC/Laptop. It would be bonus if it could work with my RX-Z7 Home Theatre Amp, but it's not something I would pay significantly for. Portability isn't really interesting to me, unless I could get equivalent sound from the portable option.

 

I am not sure how to measure everything against potential. If we said that the HD650 was a factor of 1, and the STX was a fact of say 5 (if that's the case) and 10 is the best that the HD650's could ever sound, then where would the options listed above rank? I know it's a little opinion based, and I would prefer no hysteria, but I am happy to spend some money if there is perceptable differences. I am not really interested in spending $500 for a 1-2% difference that it would be questionable I'd notice.

 

Any advice gratefully accepted. 

 

One Final Question;

 

Do you think the HE400's are different/good enough to buy to try against or to complement the HD650's?

Yes. Your amp is the biggest issue at the moment. When purchasing headphones, and their accompanying headphone amps, one of the biggest things to look for is headphone impedance.

 

If you look at the specifications in page 4 of the Dragonfly brochure: http://www.audioquest.com/wp-content/uploads/2012/08/DragonFly-4pg-Brochure-EN-R1.pdf

 

"Maximum headphone driver out power" is listed at 32 ohms. This is way too low for your Sennheiser HD-650, as they have an impedance of around 300 ohms (I don't know the exact number; I suppose someone else can chime in). So you must find a headphone amp that has a power output of at least 300 ohms.

 

Hope that helps. Don't give up on the Sennheisers just yet!

I'm surprised that there are a lot of people improperly driving their Sennheiser phones. I'm seeing people say they're using cheap ~$100 amps, like the Fiio's, or Pico's, and then in the same post, complain about their headphones not sounding good. Well, it's no wonder - they're using the wrong amps!

Couldn't agree more!

Well, tonight's listening session is really great. These phones are excellent. The detail is the best I've heard yet. Better then the Shure SE535ltd I had.

I've been running in the HD650 for maybe 16 hours and I'm not usually a believer in these things, but I'm starting to understand the 650 is pretty faithful to the recording. If there is deep bass in the song, it'll be there.

I have a little dot mkIII on the way. So hope that will scale things up even more.

I'm liking these a lot. Just had to give them some time.

I have to agree with that Ive still got the 535's and enjoy them but the detail on hd650's is pretty amazing.

post #8803 of 19746
Just to be clear, the Dragonfly pairs up beautifully with the HD650's. I have had the DF for several months now and using the MBPro>AIFF Lossless files>Amarra>DF>HD650's combo is terrific with plenty of (rational) volume.

I think keevs wants some more volume, the official dragonfly spec maximum headphone impedance 127mw/32 ohms which would give just over 13mw/300 ohms which is very low.

post #8805 of 19746

You can SPEC all you want , but the DF drives the HD650's to a very nice level with the MBPro. As a metal fan, I have not been disappointed in their max level. Of course long term hearing is optional....but, as always, YMMV....wink.gif
