I don’t have to worry about charging them constantly, which is so convenient, especially on long days when I need them for work or just unwinding with some music. The Type-C fast charging is a nice touch, allowing for quick juice-ups when needed.The sound quality is crisp, and the 13mm bass drivers deliver a surprisingly deep and punchy sound. Whether I’m jamming to my favorite playlist or watching videos, the audio is clear and immersive.I also really appreciate the Clear Calling feature, with 4 mics ensuring that my voice is loud and clear during calls. Even in a noisy environment, I haven’t had any issues with the quality of my calls, which is a huge plus for both work and personal use.As someone who enjoys gaming, the 45ms low latency gaming feature is a game-changer! There’s no lag, and I get to enjoy a seamless gaming experience without the usual delay that many Bluetooth earbuds have.Finally, the ergonomic design with a premium grip ensures that the earbuds stay snug in my ears, no matter what I’m doing.
