Regardless I’ll try Mobius out when I receive it and ignore the hissing if it’s present in my unit while posting impressions

Why the hell would you do that?

Why the hell would you do that?

To fairly evaluate the sound quality/features while Audeze sorts it out. Of course I’ll let you guys know if my Mobius unit has a noticeable hiss but won’t let it cloud my impressions too much unless it makes it too annoying to use the headphones.

This is concerning. 35dB of hiss is unacceptable. Why create such a high-quality headphone if it’s just going to be ruined by a loud hissing that is not representative of active headphones in 2018? I assume this is a defect and not within acceptable spec.

Regardless I’ll try Mobius out when I receive it and ignore the hissing if it’s present in my unit while posting impressions. It will be inconvenient to ship back two units but it’s entirely possible it’s isolated or fixable via firmware. I’d give Audeze the benefit of the doubt.

35DB of hiss? Where did you get this number?

@Kazekeil’s estimate.

So with 2 kids, 3 parrots, 2 large dogs and my pc set up being in the living room with the wife watching tv or playing games (and my tinnitus) how much of this “hiss” do you think I can expect to hear when I sit down to a gaming session? Mind you it isn’t always loud in my house, though you can always expect constant noise until the later hours

I used 35db as an example, most room noise being 35db. But for me personally, the hiss is about as loud as my room ambience. We would need that chart to know how much the hiss actually is. I updated my post to use X instead of a number, that was my bad.

 

[MICHAELSD]

If it’s found to be within spec and as annoying as you guys find the hiss to be, then yeah I’ll fairly criticize it. For now though we don’t know whether it is to Audeze’s QC spec or some unforeseen production issue/defect.

 

[AlwaysForward]

@AlwaysForward Could you post the graphs Audeze sent you? The noise specs are absent on the Mobius page. This could help prospective buyers make a more informed decision

I don’t have them.

 

[RamSpencer]

Hmm..... If it is this amp and not something otherwise resolvable, maybe they could add some kind of ANC to the design of the headset only to control the hiss, with inverted phase. I'm confused. People at Audeze have the ears. To many people are noticing this hum and are finding it disturbing. I'll have to give it a listen for myself if it's within spec. I'm definitely confused. I actually wasn't quite expecting a totally black background because of the power of these amps, but I was expecting a very well controlled and non distracting noise floor.

Eh. It’s acceptable. It’s not loud. The music & movies sound great! I think the commentary is chasing a criticism which is probably not a deal breaker for most and is not for me. As I stated PAGES ago. It’s not a deal breaker for me.

Guys. These things sound really good.

Is the background black as the pit of death? No.

Do they sound better than the PX & QC35? Yes.
(isine is still the best portable sound)

Are they comfy as heck? Yes.

Are they sexy? No.

Are they amazing for surround? Absolutely, you already know this.

Are you ok with this trade off for this performance at this price? If mine is working as intended, I’ll be fine.

Though everyone should temper expectations around it. If mine are indeed working as intended, They’re not a zero compromise solution & will probably dash @MICHAELSD’s hopes of One Ring to Rule Them All.

 

[AlwaysForward]

If, and it’s an if, mine are working as intended; I think we can assume the voices who chirped about the target market being gamers were correct.

Yes, this is an Audeze product and sounds like it. It has spectacular Audeze sound!

I talk a lot about product design optimization, as @MICHAELSD knows very well. You’re always optimizing for the perfect pro/con sheet on your target.

Eh, I could get over the hiss if it’s within spec and the sound quality is as good as the early impressions indicate. Momentum 2.0 has always-on ANC and my expectations are more or less for Mobius to sound as good or better than my EL-8 with better wireless performance than the Momentum. I’m sure I could justify a bit of a hiss to use Mobius over Solo3 or AirPods . Then again at this point we just don’t know whether the hiss will be a perpetual issue or addressed and fixed. Maybe some users won’t be bothered by it as you had pointed out.

Hmm. Got a delivery status update; Returned to Shipper
Not sure what happened but potential heads up.

 

[m8o]

So much for balanced amps having higher noise rejection so less susceptible to noise. J/K ... N/K.

Me too. I'm calling DHL right now to see what's going on.

EDIT: I just got off the phone with DHL and was told it was set back because the package contains Li-Ion batteries. DHL doesn't ship anything containing Li-Ion...
