Brainwavz S5 IEM Headphones Review - Page 21

post #301 of 578

Yeah Luke found the same thing when going between different sources.  That's why I'm a big proponent of everyone having their input, and simply acknowledging different set-ups, preferences etc.  The easiest thing we can do for others is (when describing what we're hearing) list gear and any personal bias we know about.

 

The next thing is to check any ego in at the door (hard to do) - but it leads to some interesting discussion when things don't get heated.

 

I'd be curious about the output impedance on the Geek Out 450 - is it listed?  Just wondering if that is a contributor - the X5 output impedance is really low (well under 1 ohm).

post #302 of 578
Just did some research and the GeekOut appears to be under 0.5 ohms - so that shouldn't be the reason.  Strange ....

More research - and it seems there are 2 impedance settings- 0.47 ohms and 47 ohms. Did you check to see what was being used as it would explain the missing bass?

Yes that's right!  GO 450 has 2 outputs, 0.47 ohms for headphone output, and 47 ohms for line out (also can be used for headphone output).

From what I observed so far, output impedance affecting multi drivers the most, less on single dynamic driver, since there is no crossover circuit.

Btw DACport has 10 ohms output impedance, it is one of my best portable DAC so far.

I guess it is not due to output impedance, but more of the characteristic of the amplifier.

 

If you're interested, here is a table of my own measurement of some gears that I have or ever tested:

 

Brand Model Output Z Avrg
Apple iPod Clsc 6th 80GB 4.69
Astell & Kern AK100 - I 21.57
Astell & Kern AK100 - II 25.16

Astell & Kern AK120 Titan 3.47
Audioquest Dragonfly 1.0c - I 0.40
Audioquest Dragonfly 1.0c - II 0.40
Centrance DACport 9.78
Fiio E12DIY (LoG) 0.19
Fiio E12DIY (HiG) 0.14
Fiio X3 0.46
Fiio X5 (LoG) 0.47
Fiio X5 (HiG) 0.43
Hifiman HM-901 0.54
Hifimediy UAE23 - I 203.26
Hifimediy UAE23 - II 222.95
Light Harmonic Geek Out 450 0.47 out 0.40
Light Harmonic Geek Out 450 47 out 43.36
Mytek Stereo 192-DSD 5.25
Nexus Nexus 7 2013 38.15
Samsung Galaxy S2 50.75
Samsung Galaxy S4 0.96
Sony NWZ-ZX1 1.56
Sony NWZ-F887 3.89
Yulong DA8 0.26

 

Measurement was using Velleman PCSU200 USB digital oscilloscope, comparing Max Vpp without load and with 33 ohms load.

Thanks - guess it's just how we interpret what is too much or too little bass then :smile:.

Yes. Varied greatly :-)
But with DACport, S5 bass is much better than when played using GO 450.
Toasting S5 now, will try again in the next few days.

The DACPort has considerably much more output impedance than the GO...  Which can lead to the different sound.  It could be the amp and DAC as well, we'd need an impedance curve for the S5 to know for sure.

That's right!  Would be great if someone has it and can post it here :normal_smile :

Can anyone do a head to head comparison to a much higher end can? Maybe some CIEM's or something close?

I could compare to the IE800, but what would be the point?

Please elaborate (bearing in mind my pair is a review sample) as to the merit of this...

FWIW I've already intimated re treble differences...
post #310 of 578

I just wrote this comparison in the Pioneer DJE1500 thread. Since it is a comparison against the S5 I thought I would post it here as well.

 

OK, I did an A/B comparison between the S5 and DJE1500 using my LG G2 at 50% volume, in both IEM's I used the stock tips that fit me best. But have put some notes in the text where I know different tips will change the sound.

 

Breathe (in the Air) - Pink Floyd

 

DJE1500 - The bass for this song is the right strength with good decay and texture and good impact. The midrange sounds very full and detailed, there is no sense of hollowness or anything missing, the midrange simply blends in perfectly with the bass. The treble is fully present in the lower registers and possibly slightly rolled off in the upper registers. The sound stage and imaging is large and extremely well placed.

 

If I switch to UE tips the treble becomes extended more to the upper registers and the upper midrange also becomes stronger. Sony tips make the bass on this track much heavier losing some of the texture. The midrange also becomes warmer and a bit more intimate. The treble looses some of it's shimmer and detail as well.

 

S5 - Bass is about the right strength for the song but lacks a bit in texture while having good impact. The midrange sounds sucked out and a bit hollow. The midrange has this issue from the lower mids straight up through the upper mids. Treble is bright and sparkly with a stronger emphasis in the upper treble registers. It is as if the midrange and lower treble all are a bit laid back in the song. This give the vocals and instruments a distant almost feel and causes the cymbals to sound very bright and tinny. The sound stage and imaging is average with instruments not sounding as well placed.

 

If I switch to UE tips the treble becomes even more clearer but the midrange also become a bit clearer, it does not remove the sucked out feeling of the song but reduces it a bit. Sony hybrid tips make this song sound much better! The cymbals sound more natural and the midrange becomes more cohesive but you will lose some of the detail in the process.

 

Using stock tips I think the DJE1500 handily wins with this song. But the UE tips sound the best to my ears with the DJE while the Sony tips really helped out the S5.

 

I will a similar comparison on Patricia Barber's Code Cool and one classical selection when I have time.

Guess I just wanted some benchmarks to give me an idea of overall sound compared to higher priced 'phones.  Guess I'll just wait for [joker]'s review.

I've promised Brainwavz to review S5. I will do some comparison for readers to get the idea of the differences with other IEMs (not to praise / hype one IEM and condemn the others).

Thanks for the review!  Looking to read more impressions from you.

If possible, test with other player as well. And if you have this album: Chesky 'The World Greatest Audiophile Vocal Recording', let us hear your impression for that album :normal_smile :

 

Thanks a lot!

My only players are my laptop and desktop (desktop I have a little dot Dac1 with Ocean tube amp and Audioengine D1). I am working on a full review of the DJE1500 and am a busy family man so will fit in any other comparisons as I have time. I don't own that Chesky album mentioned but will check it out and may buy it.

that's fine smily_headphones1.gif

Just seems strange to want to compare a $100 IEM to a $1000 IEM / CIEM, but I think I sort of get you now...
