Note Internal Rechargeable Lithium-ion Battery
This device uses an internal rechargeable lithium-ion battery that should last the lifetime of the device. If you suspect your battery may be dead, try charging it several times. If the battery does not recharge, please contact us for repair information.
Use LPS (100W less) power PS2 products
WARNING/DISPOSAL OF UNIT
Please do NOT attempt to change the battery yourself. If the battery has died, you should follow the disposal instructions below:
Never dispose of used batteries/electronics with ordinary solid wastes, since they contain toxic substances.
Always dispose of used batteries/electronics in accordance with the prevailing community regulations that apply to the disposal of batteries/electronics. If there are no local regulations concerning battery/electronics disposal, please dispose of the device in a waste bin for electronic devices.
Many electronics retailers now recycle batteries and other electronic devices at no charge. Check to see which ones in your area do so.
Leak-resistant construction
This product has been manufactured in accord with the leak-resistant standard IPX5* established by the International Electrotechnical Commission (I EC), but it may be damaged if splashed with or immersed in water.
When the unit is sprayed for a minimum of 3 minutes from all practicable directions with a stream of water delivered at 12.5 liters/min from ø 6.3 mm diameter nozzle at distance of 2.5 m, the performance of the unit shall not be impaired (although some water may penetrate).
Other precautions
The cover of the USB port plays an important role in maintaining water resistance performance. Before using the earphones, check that the cover is closed without any gap.
These headphones have been designed to resist the entry of perspiration and water, it is not completely waterproof. If used underwater exposure to large amounts of liquid can result in damage due to leaking into the headphones.
This unit is not designed to resist heat and humidity. As a result, do not use in a sauna, and do not use hair dryers or other heating devices to dry the unit.
In cold regions or other cold places, there is a risk of freezing if moisture is left adhered. This could cause a failure, so be sure to wipe off any moisture after use.
The Safety of Your Ears is in Your Hands
Get the most out of your equipment by playing it at a safe level – a level that lets the sound come through clearly without annoying blaring or distortion and, most importantly, without affecting your sensitive hearing. Sound can be deceiving. Over time, your hearing “comfort level” adapts to higher volumes of sound, so what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.
ESTABLISH A SAFE LEVEL:
Set your volume control at a low setting.
Slowly increase the sound until you can hear it comfortably and clearly, without distortion.
Once you have established a comfortable sound level, set the dial and leave it there.
BE SURE TO OBSERVE THE FOLLOWING GUIDELINES:
Do not turn up the volume so high that you can’t hear what’s around you.
Use caution or temporarily discontinue use in potentially hazardous situations.
Do not use headphones while operating a motorized vehicle; the use of headphones may create a traffic hazard and is illegal in many areas.

Bluetooth
Bluetooth wireless technology can communicate up to a distance of 10 m line of sight, however the effective communication range may differ depending on obstacles (such as human bodies, metal objects, or walls) or radio wave interference.
Radio waves generated by Bluetooth devices may affect the operation of devices such as electronic medical equipment. In some cases, this may result in accidents, therefore when in the following locations turn off the power to Bluetooth devices.
Within hospitals or clinics
Near priority seating on trains
In locations such as gas stations that have flammable gases
Near automatic doors or fire alarms
The characteristics of wireless technologies mean that audio playback on the earphones may be somewhat delayed in comparison to audio playback on the transmitting side. Therefore, video and audio may be out of sync when watching videos or playing games.
These earphones support security functionality that is in accordance with the Bluetooth standard for communications using Bluetooth wireless technology, however depending on settings, security may not be sufficient. Ensure care when using Bluetooth communications.
Be aware that NTT sonority, Inc. will in no way be held responsible for any leakage of information resulting from the use of Bluetooth communications.
