Multi-IEM Review - 352 IEMs compared (Pump Audio Earphones added 04/03/16 p. 1106) - Page 625

Sounds like a plastic soda bottle being dented as you push into it with your finger, tho somewhat more muted... At a high level it's basically the same thing, a concave enclosed surface being reversed or flexed against it's natural shape by outside pressure. Should only be happening as you adjust them in your ears but it's a sign of build quality.

Yes, the 232 is a little v-shaped which is my complaint with it as well. 

 

I don't know what you mean by brassy.

i read its something about the housing pushing on the driver

but what does it actually sound like???

or...what are the symptoms?
 


It's not the housing, it's the air pressure in your ear canal (with a good seal) that flexes the driver.

You some IEM produce very thin treble like Sennheiser CX300. I believe PFE 232's treble sounds thinner than K3003.

I wasn't happy with the transparency of PFE 232, I eventually eq'ed it to sound similar to FX700 with less mid/upper bass. But it's still not as transparent no matter how I eq'ed it and falls slightly behind of the timbre of FX700.

 

For EX1000, I believe that it has less mid/upper bass than FX700. But is there impact on the drums, like does the drums hit hard at all?

 

Thanks

CX300 treble is anything but thin. It's veiled and soft. No high end IEM produces treble like that.

What CX300 has going for it there is low magnitude high order harmonic distortion in the treble. (unlike some BA)

 

Thin treble would be something that's produced by e.g. Etymotic ER4S. Perhaps too crisp even.

 

EX1000 hits relatively hard, but not as hard as FX700. Only Atrios hit as hard.

Are you sure you're getting correct seal with PFE232? These have plenty bass and ok subbass... in fact a bit too much high bass.

K3003 has TWFK treble - it is very thin, much thinner than PFE232.

I've been spoiled and slowly turning in a basshead. I can't really complain about PFE 232 bass.

When I say thin, I meant like the cymbals are almost as if they were hit with pencils instead of drumsticks.

Therefore, there are less brassy feeling/sound on the sennheisers than AKGs (thats what someone else described, I don't own K3003)

Probably different interpretations of "thin".

 

In terms of note weight, the K3003 are quite balanced across the FR to my ears, whereas the PFE232 have an imbalance towards the lower half, with rather weighty bass and rather light/thin/feathery treble.

Reminds me of something I've read somewhere. wink.gif

K3003 are not neutral, they're V-shaped, with major bass boost at midbass and highs. The bass timbre is good, yes, but these did fail the drumstick test similar to the one above, because the highs are just TWFK and sound identically (in terms of timbre) to ones by my Brainwavz B2.

SE-5 and RE-ZERO (both equalized) do way, way better.

 

SE-5 accentuates brass, too near soundstage for some reason (phase artifacts?), sounds like instruments were recorded separately

B2 drumsticks sound like plastic, accentuates plates and slightly brass too, very slightly too wide soundstage (feels like a hole or a wall in the center)

RE-ZERO accentuates nothing in particular, but is a tiny bit too smooth, has narrowest, most laid back soundstage. (pretty nice presentation all in all)

Mids detailing is best on SE-5, closely followed by TWFK (slightly too fast, less rich), RE-ZERO is worst, slightly resonant, bell-like. (residual shoutiness? kinda like RE-272 from memory, but less)

 

Unequalized signatures: SE-5: warm and rolled off (more than GR07); RE-ZERO: neutral with mid focus; B2: v-shape with treble slant.

Best pairings: SE-5: something very analytical, like O2 or Leckertons; RE-ZERO: anything not too rolled off; B2: mid forward thicker amp like FiiO E10.

Like I said, I was talking about balance in note-weight, not frequency response. rolleyes.gif

I found the K3003 treble to sound nothing like the DBA-02 but did have similarity to the CK10, which IMO have great cymbals but can get a little hot at times.  The K3003 treble was not thin to me and has some of my favorite and most realistic cymbals to my ears without ever getting hot.  Not all twfk's are the same.

Guys what do you think of the sony MDR ex220lp? Are they any good?

Actually, these are exactly the same kind of hotness - the 4-8k kind and something 12-14k too. (Both B2 and K3003. K3003 reference filter slightly tames the 4-5k component.)
