"A feature-packed, budget headphone that fundamentally misrepresents its own fit and comfort."
The '25H Playtime' is an ideal-case test result, likely at 50% volume. In real-world use with higher volume, playback from the power-hungrier SD card, or frequent calls, expect closer to 15-18 hours.
This is a viable option for a secondary or 'beater' set of headphones where loss or damage is a real possibility. The SD card and FM radio features serve a niche user who wants to listen to audio without carrying a smartphone.
Anyone seeking genuine over-ear comfort for long sessions should avoid this product. The on-ear design directly contradicts the long battery life, as they are unlikely to be wearable for more than an hour at a time for most users.
