* Design and specifications are subject to change without notice.
* Avoid an extended use at high volume levels as your hearing may be permanently impaired. You are advised never to use headphones in such situations as driving vehicle and cycling as your ability to react to emergencies will be considerably reduced.
* On rare occasions, noise may occur when the headphone plug is connected and turned 90 degrees to lock it. Unless noise is heard with the plug in the locked position, it is not a problem. However, if noise or uneven reproduction volume occurs, there is a possibility that the headphone plug has become dirty. In such a case, wipe the plug with a dry cloth.
