Wearing headphones in warm weather or during a workout can quickly turn a great listening session into a sticky, uncomfortable experience. Heat and sweat build up around the ears, ear pads can become damp, and earbuds may slip or even suffer damage if moisture gets inside. Understanding how headphone design, materials, and care routines affect heat and moisture helps you stay comfortable and protect your gear.
How ear pad materials affect heat buildup
The material that rests against your skin plays a big role in how much heat and sweat accumulate. According to beyerdynamic’s guide on choosing ear pads, velour and artificial leather behave very differently in terms of ventilation and moisture management.
Velour vs artificial leather
Velour ear pads are soft and breathable. beyerdynamic notes that velour pads “provide better ventilation, you don’t sweat as easily as with the artificial leather model.” This makes them a practical choice for long listening sessions in warmer environments. However, the same guide points out that velour does not block outside noise as effectively because it doesn’t seal as tightly around the ear. Artificial leather ear pads, on the other hand, deliver a clearer, more detailed sound and can be wiped clean with a damp cloth, but they trap more heat and can lead to sweating sooner. For a deeper look at how different materials compare, see our ear pad material comparisons.
Memory foam and comfort
Some manufacturers add memory foam to ear pads for improved comfort. beyerdynamic describes how its PRO X headphones use viscoelastic memory foam that “wraps itself softly around your head and ears using your own body warmth and the pressure from the headband.” While memory foam can enhance the fit, the breathability still depends on the outer material. If you prioritize staying cool, look for velour or other fabric covers rather than solid synthetic leather. Worn-out pads lose their shape over time, so it helps to know when to replace them. Our guide on replacement ear pads explains what to watch for.
Open-back and semi-open designs let heat escape
The physical design of the ear cups also influences heat buildup. beyerdynamic’s overview of headphone types explains that open-back headphones “allow the heat that inevitably builds up between the ear and ear cup to escape, enabling longer and more comfortable listening sessions.” Because the outer shell is perforated, air can circulate freely. This design is ideal for home use where sound leakage is not a problem. Semi-open headphones attempt to balance this: they let low frequencies escape while dampening higher frequencies, and they also help reduce temperature around the ear, making longer wear comfortable.
Closed-back headphones, by contrast, seal the ear completely to block outside noise and prevent sound from leaking out. This sealing effect also traps heat and moisture, so they may feel warmer over time. If you often listen in hot environments, an open or semi-open model could be a better fit.

Sweat and water resistance in earbuds
For in-ear headphones, sweat resistance is a key specification. Apple’s support page on sweat and water resistance for AirPods provides clear details about what those ratings mean and their limitations. The information applies to AirPods Pro, AirPods 3, AirPods 4, and AirPods 5, but the principles are useful for understanding any earbud with an IP rating.
Understanding IP ratings
Apple states that AirPods Pro 1 and some AirPods 3 models have an IPX4 rating under IEC standard 60529, which means they are sweat and water resistant for non-water sports and exercise. Newer models like AirPods Pro 2 with USB-C case and AirPods 4 have an IP54 rating, adding dust resistance. AirPods Pro 3 and AirPods 5 carry an IP57 rating, which includes dust resistance and the ability to withstand immersion in up to 1 meter of water for 30 minutes, though Apple still warns they are not designed for swimming or showering. The “X” in IPX4 means no dust rating; the first digit indicates dust protection, the second digit water protection.
Limits of resistance and care after exposure
Apple emphasizes that “sweat, water, and dust resistance aren’t permanent conditions and can diminish over time.” The seals and acoustic membranes can be affected by soaps, shampoos, lotions, sunscreen, and other substances. After workouts, heavy sweating, or water splashes, Apple recommends wiping down the earbuds with a soft, dry, lint-free cloth and allowing them to dry completely for at least two hours before placing them in the charging case. Never use heat or compressed air to speed up drying. Also, avoid exposing earbuds to high-velocity water, saunas, or steam rooms, as these can force moisture past the seals.

Cleaning headphones after sweating
Regular cleaning prevents sweat, oils, and dirt from building up and possibly causing skin irritation or affecting sound quality. The approach differs between over-ear headphones and earbuds.
Cleaning ear pads on over-ear models
beyerdynamic’s ear pad guide notes that on many high-quality over-ear and on-ear headphones, the ear pads can be detached from the ear cups. This allows you to clean the ear cups and replace the pads if needed. Artificial leather pads can be wiped with a soap-free, damp cloth. The company advises against switching materials when replacing pads, because the material is matched to the headphone model for both comfort and sound. If you replace artificial leather with velour, for example, the contact pressure and sound signature can change noticeably. For step-by-step cleaning advice, see our article on cleaning ear pads.
Cleaning earbud meshes and bodies
Apple provides a detailed cleaning method for AirPods meshes using micellar water that contains PEG-6 Caprylic/Capric Glycerides, a soft-bristled children’s toothbrush, and distilled water. The process involves dipping the brush in micellar water, brushing the mesh in circles for about 15 seconds, blotting on a paper towel, and repeating three times, then rinsing with distilled water. After cleaning, the earbuds must dry completely for at least two hours before use or charging. For the body of the earbuds, Apple suggests wiping with a cloth slightly dampened with fresh water and drying with a soft, dry, lint-free cloth. The charging case should be cleaned with a soft, dry, lint-free cloth; if necessary, you can slightly dampen the cloth with isopropyl alcohol, but avoid getting liquid in the charging ports.
Keeping both your headphones and your skin clean and dry maximizes comfort and helps prevent long-term damage. If you experience skin irritation, check the materials and ensure you are cleaning the device after exposure to sweat or lotions.
Tips for glasses wearers
People who wear glasses face an extra challenge: the arms of the glasses can break the seal of ear pads and create pressure points. beyerdynamic’s ear pad guide suggests that over-ear headphones are generally a better choice than on-ear models because they don’t sit as firmly on the ears, exerting less pressure. Models with a low clamping force and soft, breathable velour pads can remain comfortable even after hours of use. Open-back designs, which are often lighter, also help.

Frequently asked questions
Can I use my headphones in a sauna or steam room?
Apple specifically advises against wearing AirPods in a sauna or steam room, as the high heat and moisture can damage water seals and acoustic membranes. For other headphones, check the manufacturer’s care instructions before using them in heat or steam.
How do I know when to replace ear pads?
According to beyerdynamic, you should consider replacing ear pads when they become flat, the material is scuffed, or you notice that the headphones are less comfortable or the sound quality has diminished. Worn-out pads can lose their shape and no longer create a proper seal, which reduces bass and alters the overall sound balance. There is no fixed timeline because wear depends on usage, storage, and exposure to moisture and sunlight. As soon as comfort or sound suffers, it’s time to look for replacement pads that match the original material.
Does sweat resistance last forever?
No. Apple’s documentation states that sweat and water resistance are not permanent and can diminish over time. The seals cannot be rechecked or resealed. To prolong resistance, avoid exposing the earbuds to soaps, shampoos, lotions, sunscreen, or impacts, and always dry them thoroughly after they get wet.
