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.
