HiFiMAN HE-300
Owner's Guide
Set-up and Operation
1. Please allow at least 150 hours of constant use for break-in of your new
headphone to achieve best sound quality. Volume during the break-in period
does not have to be loud and you can enjoy the HE-300 as you would
normally.
2. To connect your headphones to an amplifier, please use the supplied
cabling. The mini-coax plug with the red dot goes to the right side marked
with R. (Depending on the cable in use, the cable itself can also show L and
R on the plugs.) Push the connector straight onto the socket and then use
your fingers to tighten the washer. When tightening, please make sure to
move the washer only and not the cable as such. A loose connection can
lead to drop outs and distortion. Repeat the process with the other mini-coax
connector.
3. To clean your headphone, please use a soft, slightly damp cloth only. Do not
use any detergents and since it is an open back design, make sure not to let
any fluid enter the open sides of the headphone. The leather headband can
be maintained using standard leather care products. Should your earpads
become worn and no longer offer a good fit with your head, you can replace
them with new ones which can be supplied from your dealer or from www.
head-direct.com.
4. Note: The internal drivers do not require maintenance. Any attempt to
remove, alter or modify them will void your warranty.
