Users reported that Apple’s 4399 RMB (first price) flagship headset AirPods Max has a serious problem: the headset may condense due to the user’s sweat or wearing it for too long, and then appear. failure, or even complete failure.

According to multiple posts on YouTube, Reddit, Twitter, and Apple’s official forums, AirPods Max headphones can cause condensation under the earcups due to user sweat. The moisture will seep into the earphone from the speaker hole, causing water damage, which will cause some functions of the earphone to fail, or even be completely scrapped. It is noticed that this problem is not new. As early as January 2021, there were reports of AirPods Max condensation problems.

The issue has sparked a class-action lawsuit filed in California alleging that Apple’s AirPods Max have a “potential and material defect that causes condensation to build up inside the earcups after hours or hours of normal use.”
The plaintiffs are currently negotiating a settlement with Apple, 404 Media reported. However, Apple has not publicly acknowledged the problem. Apple told 404 Media in a statement: “Unlike other over-ear headphones, Apple’s AirPods Max ear cups are magnetic and detachable, making it easier for users to pay attention to their body when removing the ear cups. The heat creates moisture (or ‘condensation’) around the ear.” Apple says the AirPods Max don’t experience this issue under “normal use.”
The editor of Mobilesyrup said that he also encountered a similar problem. The weather was very hot at the time. When using the AirPods Max outside, when the earmuffs of the headphones were removed, there was a lot of condensation on both sides. While the headphones still work, the noise-canceling feature is disrupted by a constant hum that renders the feature unusable. Fortunately, the AirPods Max were still under warranty at the time, and they could be returned to Apple for a new pair.
