👎 Cons

While offering 26 hours of total playback, the individual earbud battery life on a single charge is not explicitly stated.
The IPX4 splash resistance protects against light moisture but does not signify full waterproofing for submersion in water.
Specific audio codecs supported (e.g., aptX, AAC) are not mentioned, which could affect high-fidelity audio transmission for some devices.
The 4-hour charging time for the ultra-compact battery case is relatively standard but not among the fastest charging solutions available.
The description emphasizes "YOUR SOUND, YOUR MOMENT" but does not detail any accompanying app or EQ settings for actual sound profile adjustments.
The "Labyrinth structure" for the microphone is mentioned as a noise reduction feature, but its effectiveness in very noisy environments is not quantified.
The product listing does not specify the included earpiece sizes (XS, S, M, L) as seen in a related product, which might be an oversight for fit customization.
