For Sale or Trade:
WTS Objective 2 and Headroom Bithead

Will Ship To: US Only

(Reopened want to sample new cans so these have to go)


O2 Price is SOLD, Total Bithead price is 35 dollars shipped. Payment via paypal please add 3% if not sending as gift.


The O2 was built by DIY audio user aerohoff around July of 2011. It's from before Nwavguy amended the design to remove the rapid powering on and off when the battery is low. So when your battery is low it'll sound like it's clipping as it rapidly shuffles between on and off. I mainly bought it for desktop use and it's never had any issues in that respect. I've used it with a bunch of headphones from the Shure SRH 840-Sennheiser HD600 and the Beyerdynamic DT880 and it's performed admirably with all of them.


I recently got the chance to upgrade so these have to go.


With all the parts included you could change the look of the amp. Or use the spare enclosure for an ODAC and stack them.


The O2 comes with it's original power supply and the following.


2x Rubber End Caps

1x WAU16-400 Power Supply

1x Red Aluminum B2-080 Enclosure

4x Additional volume knobs

1x JDS labs front panel

1x Red Button

1x Right Angle power cord extension


The Bithead includes it's instruction pamphlet
