Listen Safely

Enjoy music in moderation. According to the American Speech-Language-Hearing Association, “Use of headphones for an extended time at high volume might cause lifelong hearing impairment.” Although V-MODA makes an effort to provide an enjoyable listening experience, it is also concerned with the health and safety of its customers. We recommend that you use headphones for appropriate lengths of time at an appropriate volume.

Static electricity

If you use this unit in conditions where the air is extremely dry, you might notice slight discomfort in your ears. This is due to an accumulation of static electricity in your body and is not a malfunction of headphones. By wearing clothing made of natural fibers, you can minimize the effect of static electricity.
