IP57 is repeatedly cited as a meaningful durability upgrade for both buds and case, improving confidence for sweat, rain, and dust exposure. Reviewers still caution against treating them like dedicated swim gear.
IP52 is a standout feature in this category and is repeatedly praised as practical for sweat and light splashes, even if it is not a high waterproof rating.
The IP55 dust and water rating is a meaningful plus for rain and sweat, and reviewers generally treat it as dependable for everyday exercise. It is not intended for submersion.
The IP54 rating is frequently mentioned as a meaningful upgrade, making them suitable for workouts, rain, and dust exposure. They are not designed for submersion, so they remain a splash and sweat solution rather than a swim option.
The IP54-rated buds and case are widely viewed as good protection for sweat, rain, and light splashes. Reviewers still emphasize they are not waterproof and should not be submerged or rinsed under a faucet.
Earbuds carry an IP55-level water and dust resistance rating in most coverage, making them suitable for sweat and light rain. The case is typically not described as water resistant, so it benefits from more care.
The IPX4 rating is routinely cited as suitable for sweat and light rain. Reviewers consistently warn it is not intended for submersion or heavy water exposure.
The IPX4 rating is adequate for sweat and light rain but not for dunking or heavy water exposure; runners wanting more protection may prefer higher-rated alternatives.
Multiple reviews point out there is no official IP rating, making the Ace a weaker pick for workouts, heavy sweat, or rain exposure. Some still use it casually at the gym, but it is not positioned as a sport headphone.
Water/sweat resistance is described as absent (no waterproof rating), and at least one review cautions against heavy sweat, making them a fair-weather choice.
