Tips and Tricks

Connecting your headphones to the AirHead

It’s always a good safety measure to turn the amp OFF (or turning the volume all the 
way down) before connecting or disconnecting your headphones.

Break-In Time

Both headphones and headphone amplifiers require “break-in” (often called “burn-
in”) time before they provide optimal performance. Using your new headphone amp 
and/or  headphones  for  about  40  hours  should  provide  sufficient  break-in  time.  If 
you’d prefer some unattended burn-in, the easiest way to do this is connect your sys-
tem (source, AirHead, and headphones) as described on page 5; turn the AirHead on 
and set it to a normal listening volume; and then place your audio source in “repeat” 
mode and begin playback.

Adjusting the Volume

When adjusting the volume, turn the volume on your portable source from 3/4 to full 
volume if it doesn’t have a line out.  Then use the volume control on the amp to adjust 
the level.  If you do have a line out feature on your source, then you will want to plug 
your mini-to-mini cable in to that; and adjust the volume on your AirHead.  If your Air-
head still seems too quiet, adjust the gain switch to ‘High gain setting’.

Using two pair of headphones with the AirHead

You can run two pair of headphones off your AirHead provided that they are of similar 
impedance levels.  Consult www.headphone.com or your headphone manufacturer’s 
website to confirm your headphones’ impedance level.  (The AirHead is able to drive 
headphones of different impedance levels; however the volume level will not be the 
same between the two pair of headphones.)

Rubber and Velcro Feet for the AirHead

You will find 3 rubber feet included with your AirHead, which you may stick to the cor-
responding divets on the bottom of the AirHead.  You will also find Velcoins made out 
of both hook (the scratchy side) and loop (the softer side).  Attach the hook Velcoins 
to the bottom of your AirHead in the corresponding divets.  The loop Velcoins are to 
be used anywhere that you may want to attach the AirHead, such as the back of your 
portable player, on your computer, or inside a HeadRoom Bag.

Storing the AirHead

As with most electronic devices, we recommend removing the batteries from the Air-
Head when storing the unit for a long period of time. Even though the AirHead will not 
drain the batteries when it’s turned off, batteries sometimes leak, which can damage 
the unit.
