Phone Battery was draining fast

 
Started the phone
Started the OPUS by plugging in headphone...then connected both after both turned on.
Seems to have fixed that issue.

Excellent review, thanks a lot for sharing!

I've got a couple of questions if you don't mind (I'm seriously considering getting one of these) :

1. Does it also work with streaming services like Spotify etc.?

2. It's OK with me that it's low in power as long as it's also low (very low) on hiss, is that the case?

3. What would you say are the biggest difference in sound between this and the Mojo? I'm not expecting any detailed comparison but just from the top of your head to get some idea.

hey bro.
Thanks!
 
#1 Not sure? I am not a streamer but i will join one just to check.
 
#2 The e18 by FiiO is a big hisser and the iDSD is not a black back drop either (even using the IEM switch..). Compared to those 2 directly it is in fact pretty quiet which is part of the appeal.
**using Sony EX1000**
 
#3
I have received several items from vendors that will be and have been returned. I will not review them. None of them were new and un-boxed so it may be an inconvenience but nobody is out any money (They paid to ship to me and me to them...+/- = "0".)
I cannot rec items to folks that follow me or trust my word if I am not going to offer to buy and use them myself. It's my own view on the whole matter.
This thing was made by a company that was selling a plastic $600 DAP  ....I was expecting...not much with the hope of being surprised and was kinda blown away.
Was actually totally blown away.
 
I am on an Android
Use Neutron
 
The Mojo is outstanding. Will not work directly with my Note 4. Generic driver yes but direct it sounds and plays back at 4x normal speed. iDSD? generic yes but direct and it sound like an A.M. radio station in mono...out of range...horrible. I know that UAPP and ONKYO among others are options but it always bugged me that the one app that ID's the CPU and audio driver would not play back if i selected the option described as being the one to bypass ALSA and audio finger (Android).
 
Using an Android and Neutron and using the direct driver (the OPUS #11) v.s. the Mojo and a generic patch sounds so close it made me do the video, do the review on Head-Fi and offer to buy it from them.  The tracks I listened to while comparing the 3 (OPUS,Mojo,iDSD)
 
 

 
 

 
 
Played the Floyd track in all it's multi layered masterfully mastered glory like a ******* BOSS!!
 
Thick as a COZOY, has battery that runs 8 hours and has enough power for a IEM basshead (with some EQ).

Thanks for your answers. If you could be bothered to test 1 when you get the chance I'd really appreciate it.

I'm not a big streamer myself (I use UAPP as my player) but I find myself using Spotify more and more but the lack of support for external dac's in most cases (just like you I've tried a lot of different devices) has started to irritate me but if this works natively with Spotify as well it does indeed look like the perfect Android partner for me as well.

If Spotify works but the signal is processed by Android it honestly wouldn't be the end of the world for me as I wouldn't use Spotify for critical listening anyway.

If you're not able to test it it's of course ok but if you do get the chance I'll be very curious to read your findings.

I will let you know.
I get it.
Most everyone has a phone and the # of devices designed to work with them directly is really few and it annoys me to no end.  That little micro-b to micro-b cable got me stoked and it should be automatic. For any Android user that has scoured the internetz for a short micro-b to micro-b (we are an army of folks) they will smile as soon as they see that and the winning keeps on going from there.
 
Spotify is still not available in Japan
 
I may not be able to give you that info. Hit em up on FB and ask directly. Pretty responsive group over there at Audio Opus.
 
 
 
From the review comment section:

 Found the details of the Opus #11 in French. Here's the translated version: 
Portable audio DAC Thebit Opus # 11 is compatible with the reading of PCM 32/384 and DSD audio stream 256 via its USB input, has an auxiliary input and a battery of high autonomy.It is also compatible with iPhone, iPod and iPad, which it can support the conversion of audio files as well as the flow of online music services (Deezer, Spotify, web radio, etc.). The USB DAC Thebit Opus # 11 can thus be used with any computer and even Android smartphones and tablets that supports USB OTG audio protocol.

 
 
In a court of law that would be dismissed as heresay. It has been said though

Thanks again!

No FB for me but I'll shoot them an e-mail and ask.

OPUS has a winner on their hands.
 
Once enough folks who use their phone as their primary transport have a listen it will sell itself.

Does this need the CCK to work with an iPhone?

 If the guy in the post above you doesn't answer fire him a PM. He used it with an iphone at the London CanJam

Thanks for that. I just received a reply from a dealer I emailed. Unfortunately the 2 needs the CCK. Seems a serious limitation to me. Negates the neat form factor.

It should work as it worked for me with my dacs but I don't know for sure if it will work with the opus. Its a true lightning cable with the proper chips and stuff so it wont be messed up after an iPhone software update.
