B. DT770 M's Compared to Pro's?

post #1 of 7
Thread Starter 
Hey guys I'm new to the forums. This is my first post actually. I recently bought a pair of Beyerdynamic DT 770 Pro's, or so I thought. The seller sent me a pair of DT770 M's. I've been researching the difference and at first glance, the DT770 Pro's seem to be geared more towards studio/stage use and the DT770 M's seem to be more for drummers. I'm not a drummer or even in a band, I'm just wondering if I should return them for the Pro's; if there's any difference. Thanks.

I'm afraid it is more complicated than just the M vs Pro. Beyerdynamic has produced a whole pile of headphones all with the DT770 model number. I don't know all the combinations, but I know they have models with different impedance: 32, 80, 250 & 600 ohms

They do all sound a little different - similar, but different. The higher impedance 'phones will require an amp. I think the currently sold DT770M is 80 ohms, and I think beyer claims it has slightly more bass and more isolation - hence the idea that it is good for drummers.

I've heard that the M version for drummers doesn't sound good at all. But I have no clue as I haven't heard it. I would just return them and get the regular Pro version, if it's not too much hassle for you.

Oh yes i forgot to add that. I have the 80 ohms 770 M's and wanted the 80 ohms 770 Pros

The 770M are woeful and have no bass in comparison to the regular DT770 Pro 80ohm.

I have had both, and still have the DT770-PRO. 

 

The key is a small (about 4mm=1/4inch) hoole behind one of the yokes on each cup. The "M" does not have this hole, and provides better sound isolation at the expense of frequency response. The "PRO" has this hole, and provides less isolation but much wider (better) frequency response. 

 

The "M" also comes with vinyl pads, where the "Pro" comes with velour pads. 

 

The 2 headphones sound VERY VERY different. 

 

If you got the "M" version, I would return them.

As the others have said, spring for the PRO version and don't look back.  The 250ohm are quite balanced.
