Frequently Asked Questions
Q. What's the difference between the regular and Total models, in terms of parts and in
terms of sound quality?
A. The Total BitHead uses higher quality resistors and capacitors in the audio signal path.
See headphone.com for more details.
Q. Does the BitHead require software?
A. No the BitHead does not require any software.
Q. Does the BitHead support 24 bit audio?
A. While the computer application you are using may be able to read and play files with
various different sampling rates and word widths successfully on the BitHead, the BitHead
itself uses a good 16-bit DA converter.
Q. Can I upgrade my BitHead to a Total BitHead, or change my BitHead into a AirHead?
A. No. If you purchase an BitHead and would like to exchange it for a Total BitHead, AirHead,
or Total AirHead within the first 30 days of your purchase, you can exchange it for a full credit
towards the other unit.
Q. Why is the volume control scratchy when I turn it?
A. Because we had to make an engineering compromise in order to get the best sound qual-
ity. We could suppress the noise, but only by putting capacitors in the signal path around
the volume control to block the DC offsets. The problem is, capacitors in the signal path
would degrade the audio somewhat. We figure it's better to have a little pot noise when you
adjust the volume, and better audio purity while you listen.
Q. Can I use the line-in and USB at the same time?
A. No. While the BitHead may be powered from the USB connector, connecting an input to
the line-in disconnects the audio from the DA converter of the USB section.
Q. Will I damage my amp or headphones if I plug them in with the volume up?
A. Yes, possibly! The BitHead is a miniature power amp, and is quite capable of blowing its
miniature self up if it has to drive the short circuit of not-fully-inserted headphones. Please
be careful to have the unit off, or the volume fully down, and see that the plug is fully in-
serted when connecting headphones to the amp.
Q. Does it matter what kind of soundcard I have?
A. No. Successfully connecting the BitHead completely bypasses your computer's other
sound devices.
Q. Can the unit drain the batteries even when it's turned off?
A. It will not drain your batteries, but if you are storing the unit for a period of time, it is a
good idea to remove the batteries to prevent accidental leakage.
Q. How long do the batteries last on my BitHead?
A. The BitHead and Total BitHead can be powered for 40+ hours on 4 AAA batteries.
