Decoding the IP scale: What Bluetooth speaker waterproof ratings really mean
New guidance from Engadget clarifies the Ingress Protection standards for portable audio, distinguishing between basic splash protection and the deeper submersion capabilities of high-end devices.
As consumers increasingly rely on portable audio for outdoor and aquatic environments, understanding the technical specifications behind waterproofing has become essential. Engadget has published a detailed breakdown of the Ingress Protection (IP) scale, a standard metric used to quantify how resistant hardware is to both dust and water. The publication notes that the first digit of an IP rating indicates dust resistance on a scale of 0 to 6, while the second digit denotes water resistance on a scale of 0 to 9.
For most high-quality Bluetooth speakers, the IP67 or IPX7 ratings are the industry standard. The inclusion of an "X" in a rating such as IPX7 simply indicates that the manufacturer did not conduct a specific test for dust protection. Devices carrying these ratings are designed to withstand not only droplets and powerful jets of water but also brief periods of submersion. Engadget points out that swimming headphones typically fall within this same range, suggesting that a 7 rating is generally sufficient for most recreational water activities.
While IP69 represents the highest feasible protection level, Engadget observes that this rating is seldom seen outside of a few hyper-specialised examples. For the average consumer, the IP68 rating offers a more potent alternative to IP67. Speakers with an IP68 rating, such as the JBL Charge 6, can withstand submersion under harsher conditions and for longer periods of time. However, the article cautions that even an IP68-rated device is not fully waterproof, a distinction that is critical for buyers to understand before purchasing.
For those with more specific usage requirements, the lower end of the scale provides sufficient protection for everyday weather. Engadget advises that an IPX6 rating is the minimum recommended for shower use, though a 7 rating is preferable for greater peace of mind. For simple rain exposure, an IPX5 rating is adequate, while even an IPX2 rating can survive brief contact with rain. The guidance suggests that for most users, a 7 rating on the waterproof end will provide sufficient protection for the majority of real-world scenarios.
