This is a very true statement

+1. Totally agree.

Not trying to spam the thread, just that we got our own little sub-community in here where questions get a faster response and more attention.  So here it goes.

 

Though I obviously use my headphones for listening to music, sometime I just keep them in my ears like earplugs to isolate outside noise.  Often, they are plugged into my DAP or smartphone or laptop until I ready to start playing music.  That's when I noticed this faint white-noise level coming from probably half of my headphones, and only when they plugged into 3.5mm jack of audio device.  I'm not talking about hissing noise, but rather a faint white "electronic" noise, very low level and typically noticeable when music is not playing.  It was never bothering me much, or I was more immune to it before until recent testing ZA Doppio headphones where the level was louder and I could even hear it during quiet passages of the songs when beat drops and you have less instruments in the background with mostly vocals playing.  Doppio have a very high sensitivity, 113dB/1mW, and I think that's what contributes to it since it "amplifies" the noise floor of the ground connection of the headphone jack.  Then, I started going through my other headphones and noticed it everywhere, where those with sensitivity of 102dB/1mW and below are DEAD quite (like Tenore or RE400), while those above starting to get this faint white-noise which gets a bit higher in level, and those IEMs were in 108dB/1mW and higher sensitivity spec.

 

Is this a correct assumption?  Do you guys hear the same?  Obviously, it's hard to miss, as long as you are not playing music.  I'm pretty sure half of your headphones do that, you can definitely check it out.  Does this bother anybody or becomes a deciding factor when you are looking for headphones?  Obviously, lower sensitivity means also a lower efficiency since you will need to drive them harder to get a louder sound, but perhaps its a trade off to have a quieter noise floor?  I'm sure impedance plays a role in that too, but I wasn't able to find any relationship yet since IEMs I looked at all have low impedance and its all over the place in value.

 

So, any thought on this?

Just posted on-line my review of Zero Audio Tenore and Doppio: http://forum.xda-developers.com/showthread.php?t=2774986

 

I have been flip flopping trying to decide which one is better, etc, but at the end after 20+ hr burn in I think they are both great in their own unique way (not perfect, but very unique!!!).

 

Just a teaser with a few pictures from a full review.

 

Carbo Tenore

 

 

 

 

 

Carbo Doppio

Just pulled the trigger on the Sony xba h3. Ex1000 driver playing the lows, a full BA, and a dedicated armature tweeter, and 40 ohms. All I can think of is how powerful this thing is going to sound through an amp. I'm expecting a v signature that is out of this world. It's just too sexy to not get for the promotional $250 usd shipped asking price. I'm expecting these to be really fun.

@Twister6
Great reviews and great pictures as always!

I really fancy those Doppios. Looks as if they'll be more comfortable for me than the Tenores as well.

@Hisoundfi
I'm very interested in your findings with the H3 since I've read some mixed impressions on them.

I was pretty surprised to see that they can be had for acceptable prices locally in Norway. I could probably get a pair from my company if they're good.

What are the cheapest options for a music player with built in amp?  I see that Fiio X3 and X5 have this, but they're out of my budget.  I'd rather have one device rather than two, such as Sansa Clip + Topping NX1.

Soon, FiiO supposed to have X1, which is a scaled down version of X5 supporting only a single microSD and basic lossless formats, still will have it's signature scrolling wheel, but slimmer and smaller, and according to FiiO - will cost only $100.  You can also check to see what Penonaudio.com has to offer.  They got a bunch of daps under $200, though not sure about the sound quality or selection of DAC/amp.

it's just the sensitivity of your drivers. The more sensitive they are the more they pick up the sound of the device in idle.

Yep, that's what I figured.  Actually its a combination of high sensitivity of Doppios (113dB/1mW) and high output power of AP100 (2.2Vrms for HO!!!!).  Deadly combination lol!!!  BUT, damn, those Doppios sounds better and better by hour.  Got over 25hr of burn in and it keeps improving (especially the bass).

They need 200hrs minimum 😋😍

First it was 100hrs, now 200hrs?  Were you still noticing sound improvement after 100hrs?  I assume bass was getting better, right?  This is a first set of BA multi-drivers where burn-in makes a significant difference.  That wasn't a case in UE900, W40, or IM03...

Got the ED3 and SMSL M2 today. Pics later.

 

First impressions, both are quality, and the M2 works off my Nexus 5 without needing an extra battery.

Do you guys know who makes these headphones, and if you have it - how does it sound?  Someone just told me these are one of the best selling headphones in China (under $10).  I can't figure out brand/model.  I know it looks just like Hisoundaudio PAA-1, but those are $20.  I have been told by a reliable source the one below are $10
