Hi, I'm trying to get the Dt 770 pro but I do not have an audio interface/amplifier. Hence I have to get the 32ohm version which I am wondering if it's gonna be any better than the ath m40x. It seems the 32ohms are not as good the 80 and 250 ohm versions or ?

 

get an mdr7506 instead. beasts!

 

My DT770 250ohm is loud enough on ANY source. Even small MP3 player.
And yes, 250ohm version is better.
DT770 are very durable too, with ALL parts online to repair them.
You can buy them second hand with confidence (serious seller, of course).

mdr7506 is good too. But totally different beast.
A little less sturdy AND a little less "accurate".

Some REAL numbers (and not biased views) :

Nothing to say about ath, no experience.

 

will check them out, but are they as comfortable as the dt 770s? I'm really keen on comfort

 

really ? can anyone else confirm this?

 

I pretend ppl saying 250ohm is "hard to drive" are already deaf

 

haha, so are you able to get a point where you think its too loud on ur mobile devices? if so then that'll be enough for me cos I don't intend to listen at that kind of volumes

 

Slightly off topic, am I the only one who found the dt770 extremely brilliant with a rather average frequency response in the low mids and a rumble in the sub which is not the most pleasant either? Fortunately there are tools like realphones...!

I also prefer the 250ohm to the 80ohm for closed headphones, the 250ohm is less tiring on short and long term composition or mixing sessions, the 80ohm is more dedicated to recording on my side!

 

Lots of people say this about the 770's and the 990s. About 250 ohm Beyerdynamics, a post above mentions the 770s working with "anything" driving them without a headphones amp. That is not my experience with the DT990 Pros anyway. My interface shows headphones outputs (x2) being 55ohms, and it does not drive the 990pro @ 250 ohms. A good way to make them sound abrasive and overall bad is to crank the interface outputs into brittle distortion, due to the impedance. Using them plugged directly into Macbook is the same thing. I would just expect to need a headphones amp with them.

 

Correct me if I'm wrong, but wrong impedance not only means 'not that loud', it also means not enough juice to make low frequencies work. So an 250 ohm headphone on some weak output might lack low frequencies.

 

meaning the 32ohm would actually sound way better than the 250 on a laptop?

 

I'll let you in to a secret. Get whichever sounds the best to you for the simple reason when you enter production/ mixing / mastering you are going to be wearing them for hours on end and even if they give you a better finished article, you will HATE them before long. I know this first hand. I also know that when you have cans that sound pleasing to your ears you will very soon adapt.

I had a pair of Dt770 a long time ago and wanted so badly to like them that I ended up hating them. I sold them for silly money just so I could get anything for them.
I have a pair of M50x now and I can wear them from night until night again. I have never been happier with the way my mixes are coming out now, playing on ANY system!

When people say they are bass heavy, they aren't completely wrong, but what they fail to understand is, you learn very quickly to adapt to how the bass frequencies fit nicely in the mix

 

Possibly off topic... I have the 80 ohms. I only use them for vocals, but at the weekend I was using them for like 6-8 hours on an online meet, doing vocals live etc. The closed back pressure gave me a massive headache... I've generally only used them for 30 minutes at a time before then. Never more than 90 minutes, which I think is about the limit for closed back... Other people might experience differently but that was my experience.

I'm using a Samson C Que 8 headphone unit off Apollo. They can get seriously loud with that setup. I couldn't push all levels to the max, my head would blow off.

I use open back for making music and have them on for 10 hours or whatever with no issues really.

 

are you talking about the m50x?
i have a pair too, always thought they're pretty flat, even in the lower frequencies.

personally i try to avoid mixing in headphones (it tires my ears really fast). use my speakers most of the time

 

The DT990 are meant to be considered flat, but compared to them, m50x are most definitely bassier, but I wouldn't hesitate to replace them should I need to!

I know also, people talk about soundstage and the 3d effect is better on the DT990, but they literally started to drive me insane.

I think I noticed the difference more because I went straight from one to the other!

 

7506: They are not comfy for extended use. I usually wear regular listening headphones to make music/sounds, then switch to the 7506's for more technical stuff.
I am looking at the Beyerdynamics also (like you) as an upgrade.
This video helped:

 

i have DT990 250ohm and love them nice flat response if i have to mix at night and dont want to disturb my roomates i also have m50x and they are comparable the DT990 are way more comfortable on my fat head

 

Huh. It's been about 35 years now that i found out, about 3/4 of the people buying headphones are driving them with the wrong output.
I usually avoid these threads as they always end up in debates. But what is this i am reading.

Generally you shouldn't buy the 250Ω model. Not without the proper pre amp. Read on please.

Lemme start by stating that the DT 770 Pro 250Ω vs the 32Ω aesthetically is better but also about 20% heavier. It will have a slightly better dynamic range as well. And without any proper pre it is mostly dead quiet haha. But what's this you 're saying.
You claim that when you hook your 250Ω 770s to a low impedance source like an i-pod's 32Ω headphone out, it's loud enough. Err it can't be. Simple science says you are either wrong or 50db (mild conversation volume) is loud enough for you.
But let's pretend for a sec volume isn't everything.
It will still be playing kinda wrong because the much lower impedance will not be able to produce adequate bass on the 250Ω headphones. Unless you crank it all the way up and then you find it still ain't loud enough haha. If it was there would be no reason to make a 32Ω model. And a 80Ω as well. Beyer engineers can be many devious things but they 're definitely not stupid. Neither is Apple when they recommend the 32Ω version for their low impedance outs.
Let's see wtf am i saying:
I will forget your mp3 player as they 're mostly 32Ω. And these are the good ones like an Apple Ipod.
A typical best seller interface is the Scarlett 2i2, now in gen4. Max impedance on headphone out is 50Ω.
When driving a 250Ω pair, it will produce approximately 24-25mW on its hp out.
When driving a 32Ω pair it will produce 32mW. At the expense of the differences i wrote in the beginning.
Finally and most important, talking about db and loudness in the real world, the DT 770 Pro 32Ω version is about twice as loud as the 250Ω.
Now you can pretend i am deaf. This cannot change the math which is against your claim mate, which is also a bit like saying a 2 ton truck can be driven just fine with a Fiat 500 engine. Hehe.
Cheers

People often mistake impedance with sensitivity. High impedance does not mean low sensitivity. The issue with high impedance is that even though you might get it loud enough even with a phone, it will lack a bit of the punch or energy of an amp. Usually the only thing you lose is some of the "fun" of the headphones, but not really the overall sound signature. The biggest change I see from a 150~350 ohm headphones in and out of an amp is that without an amp, synths don't feel like they're sucking your brains out and bass doesn't kick as hard. The overall sound does not usually change unless the headphones are really badly designed (those you mentioned should be okay).

Check this for a better understanding of how much power the headphones need: https://www.headphonesty.com/headphone-power-calculator/

Edit: just for the sake of clarity, usually high impedance is done to eliminate noise. That's really it. Some headphones will change the frequency response slightly because R&D has to design different drivers and tune them to match the design, but the point is that they shouldn't be better or worse than each other.

Ohms is a measure of resistance. This is the easiest way to explain it to someone who is buying headphones, to make sure they do not buy the wrong thing. If the person has no idea about electronics for audio (or Algebra), explain signal flow and voltage using the analogy of water and plumbing and they will get it.
