I’ve been using these earbuds for almost a year, and they perform exceptionally well. Once fully charged, they provide hours of use. They fit comfortably in the ear and stay in place without falling out. The bass quality is impressive—try listening to a bass-heavy song, and you won’t be disappointed. Overall, it’s a fantastic product that I highly recommend.
The sound quality is excellent, and there’s minimal noise interference. They connect instantly when you open the lid. My only issue has been with the overly sensitive sensors. When I turn to the side while sleeping or place my hand near my ears, the sensors pick it up, which can be a bit frustrating as it pauses the music. While the sensitivity is beneficial, it can be annoying to have to restart the music frequently. Nevertheless, the battery life is commendable! 👍

The sound quality is impressive, and the battery life is solid as well. I use them during my workouts and daily activities. They look great and are user-friendly. The microphone quality is also decent. While the touch sensors could be improved, it’s still a great product for the price.

Connecting was a breeze. As soon as I activated Bluetooth, it began playing instantly. I purchased it for audiobooks, and the sound quality meets my needs, but it’s not suitable for music or games due to the low volume. On the plus side, it’s great for phone calls; the other person can hear me clearly. Overall, I’m satisfied with it.
