Are A90 Pro earbuds waterproof? The short answer is that they carry a water-resistance rating meant for sweat, rain and light splashes, not for swimming or submersion. This guide explains how to read that rating, what it does and does not cover, and how to use and care for the earbuds so moisture doesn’t shorten their life.

What the A90 Pro Water Rating Means

Water resistance for earbuds is usually expressed with an IP code, where “IP” stands for Ingress Protection. The first digit covers dust and solids, and the second covers liquids. A second digit of 4 generally means protection against splashes from any direction, while 7 means the device can survive temporary immersion in about one meter of water for around 30 minutes, and 8 indicates continuous immersion at a depth set by the manufacturer.

Before buying or relying on any pair, check the product page or box for the exact rating. Manufacturers’ specifications are the best source here, because marketing terms like “waterproof” are not standardized. If the listing says “water-resistant” or gives only a vague claim, treat the earbuds as sweat- and splash-resistant and nothing more.

Checking Your Specific Model

Because model details and versions change, confirm the following before you assume protection:

  • The IP rating printed on the product page, packaging or user guide.
  • Whether the rating applies to the earbuds only or also to the charging case.
  • The condition you were tested under, such as freshwater versus chlorinated water, or a specified time limit.
  • Whether the rating is for new, unused units. Seals can degrade with age and wear.

If the manufacturer’s documentation is unclear or missing, contact the brand’s support team directly and ask for the IP rating in writing. Don’t rely on secondhand summaries alone.

What Sweat and Splash Protection Covers

Earbuds with a splash-level rating generally handle the situations most people actually face:

  1. Sweat during running, gym sessions or long walks in warm weather.
  2. Light rain while commuting on foot or waiting at a bus stop.
  3. Accidental splashes from a sink, water bottle or a wet hand.

In these conditions, the sealing around the housing, charging contacts and microphone openings is designed to keep moisture from reaching the internal electronics. That said, no seal is perfect over the long term, so occasional drying after a sweaty workout is still a good habit.

What They Are Not Designed For

Splash resistance does not mean the earbuds can be used underwater. Specifically, avoid the following:

  • Swimming and diving: Pool water contains chlorine, and water pressure increases with depth. Unless the rating explicitly covers swimming, keep the earbuds out of the water.
  • Hot tubs and saunas: Heat and chemicals can degrade seals and adhesives.
  • Soap, shampoo and saltwater: These leave residue that can corrode contacts or stiffen gaskets.
  • Charging while wet: Moisture on the charging case contacts can cause corrosion or short circuits.

If you want earbuds for swimming, look for a model rated for that use, and read our guide on Ipx7 Waterproof Earbuds for Swimming: What to Know Before You Buy (2026) for what to check.

How to Use and Dry the A90 Pro Safely

Before Exposure

  1. Make sure the earbud tips and case lid are fully seated and closed.
  2. Confirm the charging case lid is shut and the contacts are dry before placing it in a bag.
  3. Keep the earbuds away from direct heat sources, such as dashboards in a parked car.

After Exposure

  1. Wipe the earbuds with a soft, dry cloth as soon as possible after a sweaty workout or rain.
  2. Shake off excess water gently, keeping the speaker mesh facing down.
  3. Leave the case open in a dry, ventilated spot for several hours before charging.
  4. Dry the charging contacts on both the case and earbuds before plugging anything in.

Common Mistakes

  • Assuming the rating covers swimming. Splash ratings are not swim ratings.
  • Charging immediately after getting wet. Wait until everything is dry.
  • Rinsing the earbuds under a tap. Pressurized water can push past seals.
  • Ignoring wear on the tips and seals. Cracked or loose tips reduce protection.
  • Using compressed air to dry the speaker. Forced air can drive moisture deeper into the housing.

Tips for Long-Term Protection

  • Clean the earbuds and case once a week with a slightly damp cloth, then dry them thoroughly.
  • Keep the charging case in a dry pocket or pouch, not loose in a gym bag with water bottles.
  • Check the manufacturer’s firmware updates, since some brands refine power management and battery behavior over time.
  • If the earbuds stop charging or one side goes silent after moisture exposure, stop using them and contact support rather than attempting repairs.

A few simple accessories can help keep water and sweat away from the A90 Pro and its case.

  • A soft microfiber cloth lets you wipe sweat and water off the housing without scratching the finish. View on Amazon
  • A small silicone or zippered pouch keeps the case protected from splashes in a bag or pocket. View on Amazon
  • A dehumidifying storage box offers a dry spot for overnight drying after heavy sweating. View on Amazon

FAQ

Are A90 Pro earbuds waterproof enough for swimming?

Not unless the manufacturer explicitly rates them for swimming. A splash or sweat rating does not account for pool chemicals, pressure or prolonged immersion.

Can I wear them in the rain?

Light rain is generally within the scope of a splash-resistant rating. Heavy downpours or standing water are riskier, so dry the earbuds promptly afterward.

Is the charging case also water resistant?

Check the product documentation, because the case and earbuds are sometimes rated differently. Keep the case dry regardless, especially the charging contacts.

How do I know if water got inside?

Signs include crackling or distorted audio, one earbud cutting out, inconsistent charging or a faint smell. If you notice these, stop using the earbuds and contact the manufacturer.

Can I use the earbuds in the shower?

Showers expose earbuds to warm, soapy, pressurized water. Unless the brand specifically approves shower use, avoid it. For a dedicated option, see Waterproof Bluetooth Earbuds Shower: How to Choose and Use Them Safely.

Does the water rating get weaker over time?

It can. Gaskets dry out, tips wear and small debris can get into seals. Regular cleaning and careful handling help maintain protection.

What should I do if the earbuds get saltwater on them?

Wipe them with a cloth dampened with fresh water, then dry thoroughly. Do not soak them. Salt residue can corrode contacts over time.

Should I consult a professional if they stop working after water exposure?

Yes. If the earbuds fail to charge, pair or produce sound after moisture exposure, contact the manufacturer or an authorized repair service rather than opening the housing yourself.

Conclusion

The A90 Pro’s water resistance is best suited to sweat, rain and everyday splashes. Check the exact IP rating for your unit, avoid swimming and submersion unless it is explicitly supported, and dry the earbuds and case after exposure. With a little care, you can keep them performing well for their intended use.
