1.Basic Knowledge of Waterproof and Dustproof Features

About IP Ratings: Key Points for Assessing Waterproof and Dustproof Features

The "IP Ratings" that indicate waterproof and dustproof performance are important criteria for assessing the environmental resistance of earphones and headphones. IP Ratings (Ingress Protection Code, International Protection Rating) are international standards that specify how well electronic devices and equipment are protected against water and solid materials (such as dust).
They are based on the standard "IEC 60529," established by the International Electrotechnical Commission (IEC). Waterproof performance ranges from IPX0 to IPX8, with higher numbers indicating superior water resistance. Similarly, dustproof performance is rated from IP0X to IP6X.

The following table outlines the indicators for each numerical rating.

Situations Where Dustproof Features Are Necessary and Their Importance

Dustproof features are critical when using earphones or headphones in environments with a lot of sand or dust, such as windy outdoor areas. For instance, in outdoor settings, fine sand and dust can enter the device and potentially cause malfunctions. Products with high dustproof ratings, such as IP6X, offer the advantage of stable use even in harsh conditions.

Moreover, dustproof features are also helpful in everyday life. For example, dustproof products are recommended to prevent earphones from becoming dusty inside bags or pockets during commutes, ensuring long-term comfort and usability.

How to Accurately Understand the Difference Between Waterproof and Water-Resistant

Understanding the difference between "waterproof" and "water-resistant" is essential for choosing the right product. "Water-resistant" refers to the ability to withstand minor exposure to rain or light splashes. In contrast, "waterproof" indicates a higher level of water resistance, capable of withstanding immersion at specific depths without damage. For example, IPX4 indicates water resistance, suitable for activities like running in light rain or sweat exposure, but not for submersion. On the other hand, IPX5 or higher is considered waterproof, and IPX7 or IPX8 can even be used underwater (specific conditions vary by manufacturer).

When selecting earphones or headphones for sports or outdoor activities, it is crucial to choose a grade that matches your activity. Understanding this difference ensures prolonged and comfortable product use.

2. What Earphones or Speakers Meet Actual IP Standards?

Understanding terms related to waterproof and dustproof features is vital when selecting earphones or headphones. These terms serve as indicators of product performance and are a benchmark for verifying the extent of waterproof or dustproof capabilities. In practice, products with low ratings like IP22 are rare. This section provides detailed examples of products rated IPX4 and higher.

IPX4: SOUNDPEATS Air3 Deluxe HS

IPX indicates no dustproof performance, and IPX4 refers to resistance to water and splashes. It is suitable for enduring sweat during running or light rain but is not intended for submersion.

IP55: Edifier X5 Pro

IP55 earphones are designed with both waterproof and dustproof capabilities. Specifically, they are suitable for outdoor use in environments with rain or dust and for light washing, such as rinsing off mud. They can handle everyday water exposure, such as light water flow from a shower, without any issues.

IP55: audio technica ATH-CKS30TW

These are also IP55-rated, offering both waterproof and dustproof capabilities. An IP55 rating provides sufficient water resistance for daily life, making it a highly functional choice for earphones intended for regular, everyday use.

IPX7: EarFun Free 2S

Although it does not provide dustproof capabilities due to the IPX rating, IPX7 offers waterproof protection against temporary submersion.
Specifically, this means it can handle being dropped into a puddle, as long as it is retrieved promptly. It is resistant to shower splashes and rain exposure. Temporary use underwater (up to 1 meter depth, within 30 minutes) is also possible. IPX7 provides a high level of water resistance, making the EarFun Free 2S, available for around 5000 yen, a great choice with excellent sound quality.

IPX67: EarFun UBOOM L

IP67 provides protection against temporary submersion in water and complete protection against dust, making it one of the highest classes of waterproof and dustproof performance.
Products with an IP67 rating are often speakers or bone conduction earphones, which may reflect the specific requirements of these devices.

3. Tips for Choosing: How to Find the Right Product for You

Consider Both Waterproofing and Fit

While waterproof performance is an important factor when selecting waterproof earphones or headphones, the fit is also an essential element. If you plan to use them for long periods, a poor fit can put significant strain on your ears, compromising comfort. For activities like running or sports, models with ear hooks that stay in place or those with adjustable ear tips are recommended.

Additionally, if you are looking for true wireless earphones, it's a good idea to choose brands that offer a variety of sizes to match your ear shape. By considering both waterproof performance and fit tailored to your usage scenario, you can enjoy a more comfortable experience.

How to Choose Waterproof Models by Budget

Waterproof earphones and headphones come in a wide range of prices, depending on the performance and brand. In the lower price range, models with basic waterproof performance, like IPX5, are common and suitable for commuting or daily use. In the mid-range, models with IPX7 or IPX8 ratings offer enhanced waterproofing along with better sound quality and longer battery life.

In the higher price range, you’ll find models with more convenient features such as noise cancellation and multi-point connectivity. It’s important to clarify your needs based on your budget and choose the best model accordingly.

Evolving Waterproof Standards to Watch for in New Models

Waterproof standards for earphones and headphones are constantly evolving, and new products are expected to offer even better waterproof performance. Models with high waterproof ratings like IPX7 or IPX8 are designed to be used confidently even in rainy conditions or while swimming. However, it’s important to check for "IPXX" markings to ensure they also have dustproof performance, as the IPX standard may not always include it.

Furthermore, many new models offer improvements not only in waterproofing but also in sound quality, connection stability, and ambient sound modes. If you're looking for multi-functionality in addition to waterproofing, be sure to check out the latest models with advanced features.

4. Conclusion

This article has covered waterproofing, dustproofing, and their respective standards. These features are becoming increasingly necessary for daily use, so consider the cost-performance ratio and sound quality when choosing earphones that suit your needs.
