Beyerdynamic DT 270 PRO

[solderdude]

Interesting linearity from 200hz to 10khz for the the H200.
Did you feel the bass was too much below 100 hz ?

A little bit on some recordings but not in an annoying way.
Very impressive when watching movies.

I lightly modified my H200 as the upper treble is audibly rolled-off in stock form.
The bass also shifted a bit lower and got 1dB lower in level, treble now extends to 15kHz.

For a closed headphone in this price class the tonal balance is really nice.

The ADAM Audio H200 is a good alternative for the DT 270 PRO.
It is similar priced but has oval memory foam pads and comes with a plug-in for a DAW.

Which one has better sound insulation?

 

[solderdude]

The H200 marginally.
Both headphones have internal ported +sealed enclosures in their also ported cups.

Very easy to improve the sound quality of this cheap (€ 32.-) Thomann exclusive headphone.

This seems to be the same headphone as the Soncie Meory G50 tested by @Jeromeof

Hi,

I tried the Adam H200 and they are interesting headphones.
First the build quality is very good to me and the cable is flexible and non microphonic.
The clamping force is high but at least they stay on the head.

In the audio part they didn't put aside on the road the K371 once more.

First, the extra sub-bass (under 100 Hz) is not annoying and like Solderdude wrote, it doesn't bleed into the mids.
They have no big dip in the mids like the AKG but, on a track like "Tell me something I don't know" from Celeste, I felt the electric guitar is too prominent and fatiguing.

I think it is very subtle but, if we look at the FR graph of Solderdude, I think it comes from the bit elevated ~2,8 kHz. There are 2-3 dB more and we know +3 dB is doubling the volume.

In direct comparison the K371 was more dark and it was welcome (still about this fatiguing electric guitar).

To me they have close sound signature and they are both great headphones, depending of the individual variations around 3 kHz.

@solderdude Hi man, honestly thx for your work, you're a legend, I have a question if you can answer, do the dt 270 pro have more low end than dt 770 pro, on this measurment graph https://gadgetrytech.squig.link/hea...dynamic_DT_270_Pro,beyerdynamic_DT_770_80_ohm , it seems like they don't, I am trying to make a decision between these 2 as I am looking for a closed back under 200, and I don't really like too much boosted bass that bleds into low mids, prefer more neutral, and some decent sound isolation, thx.

 

[solderdude]

I have never measured the 80 ohm version.
DT270 pro bass levels are too much but no piercing treble.

With modifications or EQ the DT270pro sounds very good.
Pad diameter is a bit on the small side for people with larger ears.

I think my Shure 440A are better. The oval earcups are comfortable, they don't touch anything, the sound is good, they're lightweight, and don't pinch.
Especially if you need to adjust the 270 with an equalizer.

The manufacturer probably wanted pocket/portable headphones, so they saved on the earcup size. Initially, I was only interested in them because the driver is in a separate capsule.

This headphone is likely a mess tonally. You can tell looking at the response curve.

This is a neutral headphone response curve.

And the beyers (I should stretch this so they are the same but I'm on my phone)

The beyerdynamic DT270 has a downward tilt from 100hz to 20khz, except for when it matches bass at like 14khz. No. This is all wrong.

I had a pair of DT990s for years and I enjoyed them because I got used to how they sounded. I liked them way more when I tuned them with corrective EQ.. But After moving to Sennheiser HD650s, I'd take the 650s unturned over the tuned Beyerdyanmics every time. Transitents are better, imaging is solid, and the mid range on the HD650 is very accurate.

These 270s I bet sound boomy and shimmery. Look at the roll of the preference curve. The beyers do the exact opposite even in a broad sense.

 

[solderdude]

This headphone is likely a mess tonally. You can tell looking at the response curve.

That preference curve you posted is only valid for GRAS 43AG fixture with Harman 2018 Over-ear target applied.
In my plot the reference is a horizontal line and is not to Harman target but my own target and not measured on GRAS fixture.

Thus you are comparing apples to cabbages (not even oranges) which makes you draw incorrect conclusions.
Always best to only compare plots made on the exact same fixture.

FYI below comparisons between DT 270 PRO and DT 990/250, HD 650 and HD 560S

The DT 270 PRO is actually quite comparable to the ADAM Audio H200

Hi,

I received and tried the Beyer DT270. The build quality is good for the price and my ears are tiny enough for being totally in the earcups. The cable is flexible and non microphonic . The included USB dongle is welcomed.

They are surely interesting headphones (better than average I'm mostly sure) but sill a bit too much bass :

I have the same feeling than the Simgot EP5 (I would not be surprised if they measure closely) : high-mids have more brilliance, punch and sparkle than the AKG K371 (with its dip at ~4 kHz) notably on cymbals and electric guitar BUT the upper bass (let's say at 100 Hz and more) are droning, resulting in masking the voices (notably male voice) and the true sub-bass (the AKG have these sub-bass).

I tested on this track among others :

With the Beyer I have to increase the volume to hear better Thom Yorke voice but... it doesn't work of course.
Well, the problem is really the too much upper bass masking other frequencies.

In comparison, the AKG "breathe wider" with this non feeling of too much bass.

It's a shame because the Beyer and the Simgot have good mids and highs, at the right level, but the bass is a no way for me. As usual, I'm looking for headphones that sound good without EQ (when I plug them into my keyboards there is no parametric EQ possible).

Despite its defaults, the AKG is good without EQ, the Beyer and Simgot need bass shelf.
Instead of trying to find better than the AKG, I'll buy a second pair of these as a spare, from now.

For people using EQ, both the Beyer DT270 and Simgot EP5 are good headphones with good build quality and comfort. The Simgot is well made too with its aluminum headband and pretty large earcups + we can find it for 80 €.



Ones of the measurements I trust the most are those from Unheardlab (it fits what I hear). The EP5 would be very improved from JT1...

Beyerdynamic just released a frequency response correction plugin. Will this improve the overall performance of this product? I'm also trying to find a relatively inexpensive mixing headphone with a default frequency response that is as flat as possible and close to a diffuse-field curve to meet my bedroom music production and mixing monitoring needs.

How does this one compare to the DT 700 Pro X without EQ? Which one would you pick overall?

Without EQ the DT 270 PRO would be my preference but... one has to keep in mind the internal diameter of the pads is smaller in the DT 270 PRO (50mm versus 55mm).
My ears simply don't with in 50mm diameter pads and personally require at least 65mm 'height'.

 

[nvtinh94]

Would need to buy one and it appears to be an 'improved JT1'.
I would likely have to sell it afterwards as I hate to return stuff to sellers.

If someone in EU has one as a loaner I could measure/review it.

Thank you for your review. I'm wondering between these and fiio FT1. My main use is to plug it in to a bluetooth dongle and use it around the house doing chores so i would like the headphone to stay sturdy on my head when i move. I'll also EQ it so which one is easier to EQ in your opinion?

 

[solderdude]

It depends on the size of your ears and head mainly as well as preference in comfort, weight, looks and size.
Both are easy to EQ and they aren't that far apart in price and performance and even in sound.

I lowered the bass on mine..

Are the details available?

Does anyone know if Amir is going to be reviewing these? I think it's fair to say that Beyers haven't always been his favouyrite headphones, so it'd be interesting to see what he says.

I'm looking at buying a new pair of headphones in a few months, which need to be closed back, fairly accurate, EQ-able to full accuracy, and relatively cheap. At the moment my shortlist is AKG K261/361, the FiiO FT1s or these.

 

[solderdude]

Adam Audio H200 could also be on that list.

With a small modification the H200 improves a bit:
