Try to get myself to add the Beyer DT990 Pro 250-Ohm ($180) to my collection.
Someone please post some positive reasons for buying the DT990 Pro 250-Ohm.

Take a look at this link, I'm sure it is equally applicable to DT770/880 or 990.  The drivers are the same, the difference is sealed, semi-open and open.

It is a useful link, but not in this particular case, since it compares different impedances of the DT770/880/990 drivers, while the question to be answered here is if a DT990 Pro 250 Ohm is a sufficient upgrade from a DT770 Pro 250 Ohm which the OP already has, and how the sound differs.

Thanks, I already saw that webpage last week.

I'm not looking for an "upgrade", The DT770 Pro 250-Ohm are great for closed headphone and clear sound.
Just like the idea of the DT990 having lots of bass and treble

Go read the very first post in this thread, that will probably answer your questions.
Beyer claims that their higher impedance drivers (600 ohm) are lighter, and therefore respond better to the signal.............once again, two thumbs up for your 336 purchase!
 

 

 
I have read all thread I think i will go with 990 pro's for starters since they are much cheaper and use same drivers.
Thanks for help everyone!

in other words you don't know the answer either.............

I think I worded my answer wrong. I mean the 250Ohm pro and 250Ohm premium use the same drivers. As does the DT770 and DT990. All 250Ohm driver for the DT880 are the same, same goes for the DT990 and DT770. Each DT model has different driver from the other models at the same impedance. I know the Pro 250Ohm driver has the same part number as the Premium 250Ohm driver. Kinda confusing I know. 
 
Any easy way to look at it as all DT880 250Ohm drivers are the same. All DT990 250Ohm drivers are the same. All DT770 250Ohm drivers are the same. So premium and Pro 250Ohm driver are the same within that models line.
 
As you know the DT880, DT990, and DT770 drivers are all constructed differently.
 

1. DT880 32Ohm / 250Ohm / 600Ohm: Having the black felt in front of the driver and mesh over the magnet. The felt tames the highs a bit and the mesh is used to tune the driver somehow, though I am not sure. I suspect the mesh limits airflow and decreases the soundstage. The inside of the cups have small vents that are quite small. The center of the cup is a circular opening. This headphone is labeled as semi-open but I still consider it open, just not as open as say other headphones. On the back, on the inside of the cup, there is a think ring of felt with a opening cut in it so the headphone can vent through the cup. The felt helps to dampen back waves and reduce coloration.
    
2. DT990 32Ohm / 250Ohm / 600Ohm: Not having either of those and thus sounds more open. With the felt gone the sound would be much more open and also brighter. Without the mesh the soundstage, in theory, should be bigger. As with the DT880, there is a ring of felt in the cup on the inside that has a area cut out so the headphone can vent. The DT990 has much bigger vents than the DT880 and thus leaks more sound out. This leads to an arier and more open sound with less coloration due to sound reverberations within the cup.
    
3. DT770 32Ohm / 250Ohm / 600Ohm: The main thing is that the DT770 does not have the mesh nor felt covering the driver, but has a plastic ring with spokes that goes around the entire back of the driver. Well not the entire back of the driver but the main art of it in the center with the diaphragm and magnet. The ring/spokes are lined with a thick ring of felt around the outside of the plastic ring/spokes. This tunes the driver somehow and limits some airflow. The exact specifics I do not know. The next thing is that the ear cups have a bass port on them. This tunes the bass so it won't be as boomy I suspect.
    
4. DT770 / 80Ohm: Has and enclosed/vented magnet area but nothing covering the driver. The enclosed magnet area should reduce the soundstage and lead to having more bass impact. The center of said enclosure is open in the center and has a sort of felt inlay in it. Also this model, as other DT770 models, has the additional plastic ring that goes around the magnet and is covered with felt as well as a bass port on each cup. This model is tuned a lot differently than the other DT770 models.

 
 
No the Premium 250Ohm does not sue the same drivers as the 600Ohm model. It's my bad as I worded my response bad.

I have the DT990 premium 600 Ohm and love them. I think Zombie_X misread your post thinking you were hesitating between the 250 Ohm pro and 250 Ohm premium. I don't think the 600 Ohm premium uses the same drivers as the 250 Ohm pro, maybe someone can correct me?

Well, I did not say that I do, only that the link you posted is not relevant to the decision on whether a DT990 Pro (which I do not have) is worth buying for someone who already has the DT770 Pro 250. However, I do not think it is a bad idea to get it, it will have clearer mids (no notch between 3-4 kHz), punchier bass, a possibly more "open" sound, and most people who have heard both tend to prefer the DT990.

Hey guys - long time Beyer fan here.  Has anyone ever done a comparison between the DT770 and DT150?
ZombieX, ever tried the DT150?

 

[joelpearce]

I have both the 770/600 and the 150. Later, I will do some comparing if you'd like. I've never switched back and forth directly.

Would the DT-990 Pro 250ohm be powered decently with a FiiO E10? 
I'll be ordering both next friday and I don't want to be dissapointed with my first pair of audiophile cans. (coming from un-amp'd XB500s)

I feel the E10 drives my DT770/600 fine- plenty of volume. The bass boost can be fun too.

 

[Zombie_X]

No I have not tried one yet, but I did own the DT250. The DT250 was similar to the DT770/80Ohm in many ways as it was very bass heavy and had shallow mids and slightly rolled treble. The soundstage of the DT250 was also much smaller and the headphone's weren't that comfortable at all.

That would be great.  I used to own the 770/600 with leather earpads.  I've not had the opportunity to A/B them with the DT150 as I'd sold them.  I regret selling them now.  From memory only, I recall the DT770 having better quality bass, but not necessarily more bass.  The DT770/600 was way better with the tube amp vs. the DT150.  It would be interesting to hear your impressions of the two, especially if you're using a solid state amp.  I suspect they'd be very similar with the solid state.
 
Anyway, I love the DT150.  My only complaint comfort wise are the pleather pads for long listening sessions.  The DT100 velour pads fit the DT150.  I plan on purchasing some soon.

 

[Aegir]

So much to love about the Beyers

 
I need open cans.  My next purchase is going to be the DT880 Pro 250 ohm. 
 
I'm a little indecisive between the 600 ohm premium and the 250 ohm pro, but in the end I think the 250 ohm version would be better with my solid state amp - Nuforce HDP. 
 
I'm curious to hear from anyone who is using either the 250 or 600 ohm DT880 with this amp, and if anyone agrees that the 250 Ohm would be a better choice for the Nuforce HDP or a solid state amp in general.
 
I like bass, so I figure the Pro DT880 would give slightly more bass with it's higher clamping force, vs. the premium.  I don't think the HDP has what it takes to drive the 600 ohm to their fullest potential.
 
On a side note, has anyone seen the 88 year limited edition DT770 Pro 32 ohm available this March?  They look pretty sweet.  Pleather pads vs. velours so these should have crazy bass.
