DT 770 Pro / 250 -- where's the bass?

post #1 of 39

Thread Starter 
I bought the DT 770 Pros because of the crazy huge [insert superlative here] bass that they have. However, I have been kinda disappointed in the subbass extension.

Take this sound clip (bass freq sonogram for it). The lowest notes in the bassline are pretty much missing -- that's approx 35hz. The 2nd lowest note sounds faded. I tried EQing to compensate, but I don't have very precise EQs, so I just tried turning up the 31hz band on a digital EQ plugin for Winamp. Didn't really seem to help, was a stretch.

What am I doing wrong?

The DT 770 Pros are being driven by the Echo Indigo PCMCIA soundcard... it has a built-in headphone amp.. maybe this amp is not powerful enough? Normal headphones get really loud off that amp.

Any suggestions are appreciated!

Isn't it the 80 ohm model thats the bass-monster.... not the 250?

Yep. The 250 ohm might find trouble getting driven properly by the dinky headphone amp in that laptop soundcard there. Don't get me wrong, it can still do the but you'll just have to get a beefier amp that you usually would. Pimeta, anyone?

so is it just the amp that's a problem, or is it that I got the 250ohm version and not the 80ohm version?

Which amp should I get? I'm looking for deep bass, low cost, and midrange/clarity is not as important.

Even the 600 Ohm can give you the monster bass - you just need a BEEFY amp for it. I think the 250 is perfectly fine with something like a Portaphile or Supermacro, which you can find under 200 used easy, or even a DIY portable pimeta for 150 or under if you are lucky. a sub 100 Cmoy? hmm, dunno...

The 250 is a bass monster when properly powered. I had great results with the supermacro amps, the emotion+, and the mpx3...

Oh this sounds great on my 3000s - almost created a vacuum in the ears from that low frequency. Yes I heard the 80s are far better but cost around $50 more, although are easier and cheaper to power. Also make sure your source can do that range, not all sound cards can.

BTW, what album is this from? I need some good drum and bass!

Sounds clear on my Super.fis.

Bigger amp!

Not a fan of DnB though.

I have a friend w/ a headphone amp.. I shall bring the track to him and try it there.. he has a DIY kit, forget which one.

this track is CLS & Wax - October Star off the Rubik Records "Lost Language" EP RRT010. the track came from my december '05 liquid drum'n'bass mix... you can download an mp3 of it if you like this type of thing.

anyways, i am hoping that it's the amp. if so, i can go find a better amp and see whether i can hear the bass extend lower.

thanks for your suggestion folks, I may still be convinced that the DT 770 is a bass king

Interestingly, I can't hear the bottom bass on that track through my DT770/80s out of SM3 without putting the bass boost on the SM3 on. In a hearing test, however, this setup got me down to about 17Hz, so I can definitely hear sub-35Hz with these cans. Weird...

I owned the 250 ohm version driven by a Headsave Classic/627's and believe me - they can do bass , to the point of almost lifting the damn cups off your ears! You really need to get them an amp to feel that legendary rumble!

Could also be the quality of the MP3, in combination with a sound card source, making for a less than ideal listening experience.

Try listening to them out of a quality source with decent amplification and you will have plenty of bass.

I feel almost cruel for saying that, but I can hear it at a moderate volume with my K501. :-) But yeah, the lowest notes sound very thin in comparison with the higher bass notes.
Most good headphones should let you hear *something* but I don't know any that will reproduce such low notes properly. The best phones I have on hand for that stuff are probably the HD25-1.

You need an amp. It can be a low-cost one but you need a decent power before the 770/250 wakes up. If you power it from the Indigo it is going to sound like a bad DT880.
