Know Your Sound Tool: MW07 GO, Its IPX6 Rating And TR90
April 8, 2020
In our ongoing series featuring the design and technical aspects of our wireless earphones, headphones and bluetooth speaker, we speak with members of our Product team to learn more about what goes into the engineering of our premium audio products. In this feature we discuss the unique properties of the MW07 GO True Wireless Earphones, including the TR90 composite from which the bluetooth earbuds are crafted, and the IPX6 water resistance rating they earned.
What are some of the key features of the MW07 GO that make it perfect for workouts and training?
The MW07 GO True Wireless Earphones are designed to be lightweight and also maintain a stable fit and comfort due to multiple sizes of Fit Wings and ear tips offered with each pair. The earphones are durable and have an IPX6 water resistance rating (more on this later), while tactile buttons make it easy to control playback, even with sweaty fingers. The MW07 GO have a long battery life (boasting 22 hours total listening time), which allows you to throw a pair in your gym bag for the entire week, without needing to recharge between workouts.
Explain what TR90 is and why it is used as a core material for the MW07 GO.
TR90 is a Swiss-designed high performance polymer, used frequently in sport sunglass frames. This material is perfect for an active earphone because it’s incredibly light, durable and has excellent chemical resistance plus good biocompatibility. Interestingly, the inspiration behind the design of the MW07 GO True Wireless Earphones came from this material. Our products often evolve this way as we are always looking for and learning about interesting materials to incorporate into and improve our products. It also set us down a path of knowing that the material will ultimately enable us to create the best product in its category. That’s true of TR90 and ultimately the MW07 GO.
What measures were taken to ensure the MW07 GO can handle the demands of the consumer it was designed for?
All our products are put through dozens of tests during their development to ensure they can withstand the rigors of repeated use. We test every part of the earphone. The list is long, but some of the things we test include thermal shock, chemical resistance, humidity, salt fog, electrostatic discharge, vibration, rubbing, pulling and various kinds of drop and mechanical tests. In fact, many of our testing procedures follow US Military specs, which are significantly more demanding than industry standards.

Tell us about IPX6 and IP ratings in general. What kind of water / sweat resistance can the MW07 GO really handle?
IPX6 is part of the IP Code, or Ingress Protection Code. It’s a standard to represent how much a product can resist ingress (stuff getting in). The specific test for our level IPX6 has set parameters, including basically taking a wide-nozzle hose to spray the product in any orientation, from 3 meters away for at least 3 minutes. Ultimately the MW07 GO can endure almost any environment, short of taking them for a swim.
Which authority sets the IPX standards?
IP standards are set by the International Electrotechnical Commission, an international standards organization headquartered in Geneva, Switzerland, and led by James Shannon. The EIC fulfills a vital role in producing protocol and standards for the millions of devices containing electronics or producing electricity worldwide, ensuring products and systems perform, fit and work safely together.
