Frequently Asked Questions
Q. How long do the batteries last on my Total AirHead?
A. The AirHead and Total AirHead can be powered for approximately 40 hours on 4 AAA
batteries.
Q. Can I run my AirHead without batteries by plugging it in?
A. Yes! A power supply is available as an accessory to the AirHead. Visit www.headphone.
com to purchase an AirHead power supply.
Q. Does HeadRoom recommend using rechargeable batteries?
A. For the best sound quality, we do not recommend using rechargable batteries.
Q. What's the difference between the AirHead and the Total AirHead?
A. The Total AirHead uses exactly the same circuit board as the standard AirHead except it
is upgraded with many of the same parts as we use in our Premium and reference electron-
ics modules used in our high end amps. Resistors in the audio chain have been replaced
with super-low temperature and voltage coefficient thin-film resistors and output coupling
electrolytic capacitors have been replaced with very fast organic electrolyte Os-Con caps.
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. Can I upgrade my AirHead to a Total AirHead, or change my AirHead into a BitHead?
A. No. If you purchase an AirHead and would like to exchange it for a Total AirHead, Bit-
Head, or Total BitHead (or vise versa) within the first 30 days of your purchase, you can
exchange it for a full credit towards the other unit.
Q. What headphones are my AirHead able to drive?
A. With the exception of AKG K-1000's and electrostatic headphones, your AirHead can
drive any pair of headphones.
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
quality. 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.
