Our team works hard to respond to all inquiries as quickly as possible. We pride ourselves on the best customer service in the industry. That said, we are a small business run by humble humans who can only work so many hours in a day; therefore, we are prone to disappointing customers from time to time, particularly due to delays in after-hours responses.

All ISOtunes products come with a micro-USB charging cable, allowing them to be recharged wherever you have access to a USB port, such as through a computer, wall outlet, or adapter. 

After plugging the USB end in to a USB port, locate the charging port on the battery module of your ISOtunes product, remove the safety flap, and insert the micro-USB end into the charging port. The light on your battery module will turn red to indicate the product is charging and it will turn blue when charging is complete. 

Please note, however: do NOT recharge your ISOtunes product using a "high power" or "fast" adapter or power source above 5V or 2 Amps. This may short-circuit the product and create a defect. 

Chances are you're not doing anything wrong!

ISOtunes microphones have been designed specifically to block out steady state background noise, thereby allowing for phone calls in many loud environments, such as with vacuums, engines, machines, or saws running in the background. 

However, ISOtunes microphones are not designed to eliminate impact noises, such as gun shots, so these will still come through loud and clear on calls and are likely to make conversations difficult. 

A general pointer for increasing call quality: please ensure the control module (which houses the microphone) is not tucked around the back of your head, but rather under your right ear or otherwise not blocked from access to your mouth.

Press and hold the power button until you see the indicator light on the control module flashing red and blue. This means your product is in pairing mode. 

A Noise Reduction Rating (NRR) is a measurement of the ability of a hearing protection device to reduce sound exposure for its wearer. Measured in decibels (dB), the NRR of a hearing protector must be determined in a lab approved by the American National Standards (ANSI) in accordance with the Occupational Safety & Health Administration (OSHA). A higher NRR corresponds with a greater noise reduction ability.

All ISOtunes products are tested  in NVLAP labs to ANSI and EPA hearing protection standards and issued Noise Reduction Ratings (NRRs) accordingly. Additionally, all products are OSHA compliant, meeting both hearing protection and hearing conservation standards for a full day of use in the workplace. 

That said, each workplace may have its own specific rules and restrictions on what hearing protection devices can, cannot, or must be used to ensure prevention of hearing loss. For most facilities, the main requirement is that the Noise Reduction Rating for the devices is sufficient.

If you're unsure, simply ask your manager or company’s Safety Official to determine whether or not ISOtunes products are suitable for your workplace. And when using ISOtunes products, please abide by the rules established by your place of employment. 

Contact us if you would like more information about getting ISOtunes approved for your workplace.
