The sound quality is another highlight, with many users enjoying the rich and clear audio produced by the 14.2mm composite diaphragm. Whether it's for listening to music or making calls, the sound clarity and bass response are well-received by most buyers. The overall Hi-Fi stereo sound adds a premium touch to the experience.
However, a few customers noted that the sound lacks depth compared to more premium models. While the audio is clear, some found that the bass could be stronger and the treble a bit sharper for their liking, especially in noisy environments.
Waterproof Rating (IPX7)
90%
The IPX7 waterproof rating makes these earbuds an excellent choice for fitness enthusiasts and outdoor users. Several buyers have mentioned how well the earbuds hold up during workouts, jogging, and in wet conditions, with no issues related to sweat or light rain. This makes them a reliable option for active individuals.
Some users, however, reported that the waterproof feature does not fully protect against prolonged exposure to water. A few individuals mentioned that after extended exposure to sweat or water during intense activities, the earbuds showed slight signs of wear or connectivity issues.
