Bass on my HD650's seems to be lacking..? - Page 3

I can walk through a couple calculations if you like, to show you how much current and power it actually needs to reach high volume (I like to use 110 dB for that).


I would agree on some point. On calculation that seems to be very true but in the end it's the circuit and components' job to deliver the actual sound. For things to perform ideally we need quality caps, transformer, circuit etc. A budget cut in cost would definitely diminish the performance in some way. I am lying to you if I claim a $5 steak taste the same or even close to a lovely prime rib.

 

On the other hand, I must emphasize that one must listen to the actual sound and if possible, investigate the interior built of the DAC/Amp. Pay more and pay smart when investing in this accursed hobby.

It depends, All props color the sound in some way, some swore with neutral and some embrace colored interpretation (like tubes). As long as one enjoy and know what he is doing I think that's fine. For pros as long as they know their system well and how their hard work would be translated into other systems, that's also fine.

That sort of stuff can hurt performance, sure. But the E9 measures pretty well too, especially into high impedance loads. Expensive isn't always better, and not in every application either. Paying more is silly after a certain point (not saying the E9 is that point, but it's not objectionable at all for the HD650). I can send you a review of it if you'd like, the site itself is banned here because of objectivity or something.

Now that's silly, why would a whole site be banned from being displayed on a forum such as this?

I was wondering the same thing this morning. Forgot my speakers EQ setting on (-4dB ~100hz), then after two hours of listening and wondering noticed it, ahh the bass was back. Ok enough of trolling,

 

I listen to alot of electronic music, dubstep, house, drum and bass etc. and I'm fine with the bass amount my HD-600 gives, I was actually surprised by the amount of sub-bass when I first heard them. I have the older version with black drivers though, which supposedly is known for slightly bloated bass.

 

I tried to compare these with my Portapros (both straight out of my phone, unamped) and these have quite similar amount of sub-bass imo. The Portapros have a bump in upper bass, which sounds very annoying in comparison.

 

But anyways, these are not going to satisfy a basshead, they lack the the slam that you get from some 'phones. I would like the deepest rumble (below 50hz) be slightly louder too, maybe I will try boosting it with EQ for my electronic music needs.

 

It could be that, once you get used to your HD650 sound, you will notice the HD25 bass to sound bloated, or boosted, who knows.

i love the bass on my hd 650s. its strong enough and very textured and goes down deep. there is roll off in the really low bass, but not enough to notice on most songs.

I have been comparing my HD650s with my beloved HD495s and W5000s. Amps used were an AT-HA5000 (very handily has two outputs for easy comparison!) and a Kasuga KA-10SH (tubes). The HD650s do seem a bit weak, it has to be said. They are well known for being laid back and there is no way I'd say they have any real "punch". The volume of bass is low. It is detailed and controlled really well, there just isn't that much of it.

 

Rock suffers the worst, but electronic stuff has a hard time too. Since mine were second hand I don't know exactly how many hours they have one them so am going to do 100 hours more burn in and have another listen. I was just surprised as the 495s are open. The W5000's bass is legendary, once you get them to fit right.

Example, the beginning to Pet Shop Boys 'West End Girls' (ok, go ahead laugh! - actually I'm more of an orchestral fan but was using more rock and pop songs for testing) has an electronic kick drum during the intro, on the HD650's it sounds very flat and there is no weight behind it at all almost just a slap sound where as on the HD25-1's, there is a real oomph behind it and you get a sense of feeling the impact in your chest. It's the same for bass guitars, like the bass in Phil Collin's 'Easy Lover', it sounds all well balanced on the HD25's but unnatural on the HD650's as it is quite bass light.

 

If anyone knows the track 'Desert Search for Techno Allah' on Mr Bungle's Disco Volante, at the 1:50 mark there is an awesome weighty bass percussion effect in the background which is my usual go to passage to test bass on head phones and of course you can hear it on the HD650's but it has real impact on the HD25's...wonder what's going on with the HD650's...?

Sorry to necro an extremely old thread but I was seconds away from grabbing a pair of HD650s when I read this. I started with AKG 701s then to the JVC SZ2000's because I'm searching for that sense of feeling the impact bass in your chest. I'm at this point willing to spend upwards of 500 on a pair and sell my JVC's that I've owned for a month. I've got a Cayin C5 amp to drive whichever phones I end up with.

 

Can you tell me what you eventually settled on?

Hi! Yes old thread but advice never gets old! I kept the HD650's and am extremely happy with them and the bass, sounds more realistic, less boomy which is what I was used to with the HD 25 ii's. A substantial improvement on the HD25 ii's (though they are still excellent for portable use) and if anything the HD25's sound a tad too bass heavy. Though if you are looking for real impact, they may be a good choice.

Many thanks for the reply! I'm definitely going for realism. Not muddy, boomy, or over the top though. I tend to watch a lot of action movies and play a lot of PC games. There was a certain bass impact I felt in my chest when watching a movie trailer on my uncles home theater system I've been chasing for years now. I know I won't get that from headphones but a "sense" of it is the most promising I've heard so far here. Alas, it was on your "cheaper" headphones. Still torn, but at least I'm onto something.

IME part of the issue with the HD 25 1 ii's is the steel cable.

I replaced mine with a copper cable (made by Oyaide) and they sound

substantially better.  Cleaner, more dynamic, more open...
