Using Your realtone Headphones

There are “L” and “R” markings on the headphones. When 

worn properly the headphone cable will be on your left side 

and the volume control will be on your right side. The two ear 

cups may be adjusted up or down for most comfortable fit.

Connect the headphone plug to the headphone jack of your 

music player. Be sure that the plug is fully inserted into the 

jack. If the plug is not fully inserted you may only hear sound 

from one side of the headphones.

If you are using this headphone with an older stereo receiver that has a larger size 

headphone jack, attach the supplied 6.3mm headphone plug adapter to the 3.5mm 

headphone plug.

To protect your hearing, always start listening with the headphone Volume Control set 

to a low level and gradually increase the volume to a comfortable listening level. 

Note: You may have to adjust the volume control on your music player as well as the 

built-in Volume Control on your headphones to find the most satisfactory sound level. If 

one control is set too low and the other is set too high, the sound may be distorted. Try 

setting the volume control on your music player halfway between the Min and Max 

settings, and then use the built-in Volume Control on your realtone headphones to 

make final adjustments.

IMPORTANT! Listening at high volume for long periods of time can result in long-term 

hearing damage. For your safety, do not use headphones if they would prevent you 

from hearing warning sounds, such as while driving a car or motorcycle, riding a bike, 

etc. Remember that on-the-ear style headphones such as the RT62 may block outside 

noise, including warning sounds. Always be aware of your surroundings and do not use 

these headphones in situations that require you to hear warning sounds.
