Objective2 ODAC with Battery? or similar?

[teeshirtguy5]

Hi all
 
I'm a music producer of electronic music, it's what i do for a living and i'm working on music most of the day, most days.
 
I have access to a treated studio with great monitors that i can take stuff to mix / re run through hardware but I generally work best quite informally at home. I get most of my rough ideas out here and take it to the studio later to finish up. I like that setup and i really prefer working from my kitchen vs working from a formal studio situation
 
With that in mind, I have ok studio monitors at home but i have a bit of a phobia of annoying my neighbours / of people hearing so i tend to work either very very quietly or just on headphones (hd25 / shure se215)
 
I'm looking to commit to a better headphone, i find the hd25 super boomy and closed and the se215 super fatiguing
 
After reading around on here, general consensus seems to be the least fatiguing headphone in my rough price range is the hd650, nice and open, light etc
 
I am quite settled on that as a phone, and am looking now for an amp to match it 
 
an important thing for me is that i can move around the house easily without having to trapse around a bunch of wires so i think i want an amp/dac combo with a rechargeable battery so i don't have to move my interface round the house too
 
again after digging though this site, the objective2 seems to be a favourite for the 650's and looks to be pretty perfect for my needs
 
so to get down to the point
 
where can i get hold of an objective odac2 with a rechargeable battery?!
 
It seems the only ones around are ones people have made themselves, or the ones with batteries have no odac
 
is there an amp similar with the battery and odac?
 
and how much difference does the odac make here? could i potentially use my rme interface into the amp when im sitting at my main desk but then just use the laptop headphone out into the amp when im upstairs / moving around the house? how noticeable would that change be. could a decent solution could be just to get the straight up amp + battery w no dac?
 
 
thanks in advance

With the combined ODAC and Objective 2, the ODACs circuity goes where the battery would be in the Objective 2. So if you want battery operated Objective 2, you need ODAC and Objective 2 separates. Here you go:

now there's a nice solution
 
would you say jds odac is the best to go in terms of standalone portable dac's?
 
i'm in the UK so it's impossible to get hold of them without importing
 
i can get a standalone objective2 (not JDS) but cant find an odac here
 
just wondering if there are other options in terms of standalone battery dac's that pair well wtih o2 + hd650
 
thanks for your help

The ODAC does not have a battery. It runs off the USB port it is plugged into. Not sure what the comparable alternative would be.

I use and ODAC and O2 and Ive got no complaints with the 650. For my music production I use DT 880s, though.

Check headnhifi, they're Swiss-based

You could grab a used apex glacier for around $200 with a DAC and battery... or for that matter a headstage arrow with DAC cable.
