DT 770

You are gonna get the best luck with the 32 ohm sans amp (lower the ohms = more efficiency, usually).

As far as I know, there is little difference in SQ between the different impedances.

I just upgraded from the DT 770 Pro 80-Ohm to the DT 770 Pro 250-Ohm, the 80-Ohm is the bassy one and the 250-Ohm is more balanced,

So I like the sound of the 250-Ohm over the 80-Ohm.

I use an Indeed 6922EH hybrid tube amp. ($88, from China, bought off eBay), the 250-Ohm really needs the tube amp. to get loud.

The small single tube headphone amps from China are small enough to be call "portable", as long as you stay near an AC outlet.

As my Asus Xonar DX is pushed to it's limit for the 250-Ohm.

Anyway, the 250-Ohm is a lot cheaper then the 32-Ohm version, so that gives you more money to spend on a headphone amp.

I can also see a 250-Ohm headphone draining batteries faster then some 32 Ohm headphones.

Someone has posted a comparison of Beyerdynamic headphones

Also might consider saving a few dollars and getting some CALs (Creative Aurvana Live).

i have and love the 770/80's, and they can be driven from an iphone. volume-wise, a computer/iphone/ipod can drive them just fine; an amp will help tighten up the bass a bit and improve the soundstage, etc... i'd highly recommend the 770/80s and the Fiio E7, as well as the E3 LOD cable. the E7 is a truly awesome amp/dac for the price, as you can connect it to your iMac via USB and make your 770/80's really live up to their potential (and drive them much louder than the computer can) and when you're on the go, you can use the E3 cable from your iPhone with the E7 acting as an amp to drive the 770's. overall a great combo. it does depend on the type of music you listen to though, as it has been pointed out, the 770/80's are bassy cans which i love as an electronica listener, but if you're in search of more balanced sound the 770/80's probably aren't for you.

I have the DT 770 pro80s and they sound very good coming out of my Samsung Captivate. The iphone 4 should be enough to power the 80 ohm version (the bassiest of the beyers) without an amp and fyi if you want an amp to boost power, don't get the E7. That thing is a very weak amp, but a good DAC I've heard. 

Yea I've heard the 32 ohm is noticably less bassy than the 80 ohm. I was going to get the DT-770 Pro's in this bundle but they didn't specify which version they were at first (kind of fishy). So I e-mailed support and they told me this.

"Thank you for your email. Ouch, we made a little boo-boo.

 

The 770 pro is available in two versions 80 and 250 ohm.

 

You can have either one.

 

Many thanks, rgds, Wilson"

So I am guessing I am the reason they changed the description on the site lol but now it says available in 250 and 32 ohm... Grrr. They told me they had the 80 ohm version available and the description says otherwise. What to do, what to do.

I would guess the "32-Ohm" is misprint, normally the DT-770 32-Ohm sells by it's self for more then the price they are asking for the bundle.

Also the picture does not match the 32-Ohm version, but looks like the 80 and 250 Ohm versions.

  my suggestion for you is that you can buy a 32ohm dt770 and a portable amp to connect u ip4 .  but there  is question ,the 3m cable of dt770,  for outside is not convenience

Ah, I thought that was weird also. The 32 ohm selles for nothing less than $250 with the 80 ohm being found for around $170.

My whole experience with Jaben thus far hasn't been the greatest. Filling out a basic report to customer service gets you no reply, I had to search around for an e-mail address that would actually respond. This Wilson guy from the Jaben brother site has been the most helpful.

I just wonder what would've happened if I didn't tell them about this. Did people just order the bundle and Jaben sends them whatever version they feel like? Even at this point in time, there is no way to tell them prior to the purchase what version you want, no drop down boxes, no optional message during checkout. Just the support ticket I can fill out at the site that doesn't respond... I suppose I will shoot them another e-mail about this. Thanks for the help.

Oh, I almost forgot, if you go on the Jaben site for that bundle and click on the picture they have for it, you can see the part where it would normally say "80 ohm" is obviously blurred. Yet another thing I find fishy.
 

So they emailed me back and said they had a typo. So now the description reads "80 ohm and 250 ohm" and they added a nice little drop box to choose which version. Problem solved.

I've got a set of DT 770 80 ohm.  They sound fine on my iPhone, my android phone can't push them loud enough.  They sound best when used with my Fiio E7.  The E7 is a great DAC and the amp has plenty of power to run the DT 770, it's really not an issue in my humble opinion.  Not that's its a big deal, but I have to have the volume on the E7 turned up louder with the DT 770 compared to my ATH-50, but the E7 has plenty in reserve.  Both sets sound great through the E7 and are drastically different when used without the amp.  The ATH-50 are more forgiving when the amp isnt in the mix.  I honestly rarely listen without the E7 and never spend any quality time without it.  The bass on the DT 770 is a bit deeper/more responsive than the ATH-50, to me the rest is close enough to be called the same.  The DT 770 are comfortable and I can wear them longer than the ATH-50.

I have just gotten the 32 ohm Premiums.  they are much better served with power.

Random question.

Just got the pair of DT 770 Premiums.  They were stated to be new but "open box".

so i open em up and inside the carrying case is 4 extra little screws, that appear to not fit in anything..

wtf are these for?

or did i get screwed into some refurbs?

Even the 32ohm version needs an amp, However it still sounds excellent out of my sansa fuze or clip.  Its my favorite full size budget closed back set.  

I just purchased an upgraded model of the dt770 32 ohm, its a Luke Skybeyer, Dual entry, headphile recable, rosewood cups and old DT770 style headband with velour pads and terminated with a standard mini.  Its awesome. :)

Just wanted to state that the DT 770 Edition are now discontinued by Beyer. I just go a confirmation via Facebook, and the T70 are their official successor :

"Hi Florent,
your salesman is correct: the DT 700 premium (or as we call it DT 770 Edition) has been discontinued. If you search for something similar we recommend the DT 660 or the T 70 which is the official successor to the DT 700 Edition."

It is actually not correct that a higher impedance headphone is draining batteries more, unless it also has lower efficiency (dB/mW). Battery usage is a function of current drawn, and to produce the same power, a lower impedance headphone needs more current and less voltage, and more power is dissipated (wasted) as heat in the output stage of the device powering the headphones. Therefore, the most battery-friendly headphone is actually one with high impedance and high efficiency.

Also, I have the 250 Ohm Pro version, and it can get very loud directly from my sound cards, one of which is a Xonar D1 (basically the same as the DX, but with PCI interface instead of PCIe; it has ~1.94V maximum RMS output voltage, and slightly more than 100 Ohm resistance). Of course, everyone's definition of what is loud enough is different, but I found that even the 250 Ohm headphones need only a few tenths of a Volt (RMS) to sound sufficiently loud.

Note that the 32 Ohm version is the "Premium" one, and it sounds quite different (not as bass heavy), looks different, and has a less clamping headband than the two "Pro" versions.
