"An exceptionally cheap headset with an optimistic battery spec and questionable marketing."
The '65 Hours Playtime' spec is a theoretical maximum. It's achieved by pairing a small battery with very low-power internal components, not by virtue of a large-capacity cell.
This is a functional option for buyers whose absolute top priority is a low price. Its light weight and long potential runtime make it suitable for kids, as a travel backup, or for listening to podcasts where audio fidelity is secondary.
Anyone prioritizing audio quality, build durability, or call clarity should invest more. The fabricated Bluetooth version is a significant red flag for anyone who values transparent specs and engineering.
