Audiophile sound UNDER $100. (Old school Sony)

now just because you can spend a lot of

money on a headphone it doesn't mean

that you should I've got three

headphones here today two of which you

can get for under $50 that are truly

High Fidelity let's talk about it here's

the three headphones the first one is

the Sony cd900st the second is the

7506 and the third one is the V6 now

something you'll notice is that all

three of these don't have the stock pads

I went through yak catalog and actually

purchased this set of pads myself Yaki

sent me these other pads this video is

not sponsored but these pads do improve

the frequency response of these three

headphones the cd900st here well it's

using the yxi St Pad 2 it's definitely

the most spacious of the three and we'll

talk about sound in just a second the

7506 is using the deluxe Yi St pad not

two the one and the mdrv6 is using the

St pad ad micro suede I tested a ton of

pads on these three headphones to find

out which ones would measure and sound

the best so let's get into a subjective

sound we'll talk about frequency

response and measurements in just a bit

first off is the cd900st now I already

did a full video on this headphone you

can check it out on the headphone show

I'll have it linked in the video

description I'll also have all these

pads and everything down there just so

you can find out what it is that I'm

talking about and what pairs best more

or less the cd900st is an honest

headphone it's very truthful it does

have a fair bit of trouble but it

doesn't extend past diffuse field but

more than anything it tends to level out

around a diffuse field curve so a pretty

honest headphone just relatively similar

to how the human ear responds it has

some dips and Peaks throughout the

response but it's not insane overall

it's just a good headphone to use for

things like video editing but I also

enjoy it the MDR 756 is the closest

between the three to a true neutral

headphone it's very similar to if you

take diffuse field and add a 10 DB

downward slope from 20 to 20K which is

pretty close to what you see in line

with the Harmon research though with a

bit less of a base shelf these still do

have very deep extended base it's punchy

it's Dynamic it's just all around very

balanced very good then the

mdrv6 well it's a bit less Airy than the

7506 despite having well similarly

measuring trouble you'll see that in a

bit but what it does have is notably

more subbase so more Harmon like subbase

this one is very deep very punchy very

extended it's not overwhelming base but

it's enough subbase to uh definitely

have some kick to it and much more out

the three so you'll see the way I have

them lined up from left to right it

basically is the same way they sound

leaning towards treble neutral leaning

towards base it's as simple as that and

as far as technicalities are concerned

well they all sound basically the same

they all have similar Sound Stage detail

Imaging all of those things and those

faculties are not wowing they're not

going to blow your mind but they are

good all these headphones are decent at

sound localization so they're very good

at Imaging pinpointing the direction the

sound is coming from but also feeling

out the mic so if you have a microphone

placed in a room you can really tell how

far that microphone is from the

instrument from the singer and so on but

they don't have the stage to make it

quite as immersive as some of your more

audio file focused headphones but in a

sense that also keeps them honest

they're not insanely overwhelmingly

euphoric but basically every song is

going to get a fair play on them versus

some of my audio file headphones some

songs really Excel and some not quite so

much on these I feel like everything has

an even playing field and at their price

well that's really nice to have these

the 76s and the v6s you can both get on

eBay for under $50 the pads are another

20 to 30 which makes this a sub $100

headphone the same with the mdrv6 the

cd900st they're a little bit more

expensive than that but they're also not

insane any of these I would by used

because they basically last forever the

downside is they do have hard attached

cables but the cables are pretty durable

and if you really need to you can

replace them I replaced it on my cd900st

for a shorter one I would say all these

headphones are very good for someone who

just wants something that is neutral

leaning with one of those three flavors

either dead- on neutral a bit more bass

a bit more treble a Clos back something

good for monitoring definitely something

for work or for video editing now let's

look at frequency response I'm going to

start off with the cd900st and we did

this one with multiple output impedances

tested now I also have the raw

measurements up here for you it's

showing a diffuse field curve for the

4128 that's what I'm compensating to on

these compensated measurements and then

the actual Target line for the

compensated measurements is a 10 D

downward tilt something to note the bnk

4128 the measurement rig I'm using for

this does tend to show a trouble Peak on

most headphones somewhere in the

ballpark of 10 KZ now I'm not going to

say that these don't have some elevation

in that region because they definitely

do but it's not as severe as the peak

we're seeing seeing in these

measurements a lot of that is the rig

itself on the cd900st here we can see

that it has decent base so it does start

to roll when it gets really deep and it

basically likes to ride the line around

diffuse field and diffuse field without

much of a slope just straight up diffuse

field we see a bit of a recess at 2K we

see it Peak back up around 3.2k which is

a little bit farther up than the natural

peak of ear gain but pretty close it's a

region that people shouldn't be too

bothered by it recesses around 6K which

is actually a fre range I know a lot of

people are bothered by which is nice so

that kind of dip back in makes it a

little bit more tolerable for things

that are treble heavy and then we start

to roll off after say about 15 16 khz

probably about 15 khz now in this the

red line is normal Alid impedance the

blue line is high output impedance I'm

not seeing a difference in frequency

response realistically between output

impedance for this headphone despite it

having a nonlinear impedance let's move

on to the

7506 now we see more subbase we see more

extended base overall the mid-range is

really solid we do have a little bit of

a bump around 400 HZ and then levels

back out we don't see nearly as much of

a recess around the 2K region again we

start to peek around 3K subtly another

dip at 6K which is nice and then we go

back into the Resonance of the rig which

still again there's definitely some

elevated frequency there but it's not

quite as severe as what we're seeing

overall the 7506 well it's really

similar to diffuse field with 10 D slope

that's a really good result this is a

very neutral overall headphone

especially at its price makes it very

hard to beat and that also means it

would take very easily to things like EQ

now on a high output impedance which is

the blue line here you do see a bit of a

change so we see maybe a 3 D difference

between the base and the absolute center

of the frequency response around 1 khz

so you'll notice a little bit more base

a little bit less mid-range and treble

if you're using this on a high output

impedance amp um or or a tube amp or

anything like that but you could also do

that with an impedance adapter so you

can plug up a 40 Ohm resistor to this

headphone in line and get the same

frequency response effects and the

higher impedance of resistor you plug in

the more of that kind of Base shelf

you're going to start to get and then

the mdrv6 you can kind of see the trend

now here I imagine even more subbase we

have a little bit of a recess around 200

Hertz pretty solid mid-range throughout

we have that dip a little bit again

around 2K less recession around 6 khz

but it's still there and then back up

into the treble now overall this looks

like it would have more treble than the

mdr7506 but because that base elevation

it doesn't sound like it the 7506 sounds

more Airy than the V6 does it sounds

more full and the treble despite the V6

also being very close now the V6 is

really good it's the most harmonik of

the three headphones and I have a really

hard time picking between these which

one I like the most I pull up all three

of them side by side for you there we go

and you can see the trend more treble

leaning straight on NE neutral a little

bit more bass leaning and that's why I

have all three in my collection because

some days I want one or the other but

they're all a very similar overall sound

I use the cd900st the most for things

like playing escape from tarov or

listening to records or things like that

for almost all my other listening when

I'm using one of these three I prefer

the sound of the 7506 with these yxi

pads but there are also times when I'm

listening to something that is

electronic or very cinematic with deep

rumbling bass but I want to pull out the

mdrv6 just to get my bass fill but it's

nice having a headphone with capable

bass that doesn't sacrifice the rest of

the frequency response to do it which is

a Cardinal S A lot of headphones make

when you get really good base sometimes

you lose out on everything else and all

three of these headphones do balance in

their own unique way but also without

making major sacrifices now again

they're not as exciting as as stagy as

immersive as some other things like some

focals and whatnot but it's also a

headphone that you can get both the

headphone the pads the TXS the shipping

all that stuff for less than 100 bucks

and at that price well it's basically

impossible to beat in fact I would take

the 7506 in many cases over the AKG K

361 and 371 but it really depends on

what you're after the 361 371 are also

fantastic um but the build is better on

the 7506 it's a more kind of time tested

design and the akg's have had a little

bit more of a mixed history with their

build reliability despite being great

sounding headphones so maybe one of

these is for you maybe it's not but

there are three headphones that I

purchased that I went through measured

all the various pads on and found these

pads that work best for them I really

enjoy them personally and they're going

to stay in my collection in fact

recently I moved and for 2 weeks the

only headphones I had out were these

guys I'm still using them a lot the

reason I'm not wearing them for this

video is cuz I have my 6xx on but I

think we're going to wrap it up here if
