I was quite dissatisfied with the low quality of the headphones that I recently purchased from LASUNEY, and I returned them. The quality of the sound was poor, and there was an audible hissing in the background the entire time. It was a struggle to keep the earphones in my ears because they were so unpleasant. Given LASUNEY's promises that their items are made of high-quality sound and sturdy materials, I had high hopes for their offerings. My experience with their headphones, on the other hand, was anything but satisfying. Even after a number of attempts to change the settings and readjust the earbuds, I was unable to obtain a sound that was satisfactory. In addition, the battery life was not quite as long as it was supposed to be, and I discovered that I needed to charge the headphones on a regular basis. This was a major hassle for me, especially considering that I had purchased them in preparation for a lengthy travel. In general, I am disappointed that I purchased these headphones, and I would not suggest LASUNEY to other people. The design was sleek and beautiful, but the sound was of low quality, and the earbuds were uncomfortable. This offset whatever merits the design had in terms of aesthetics. I will be sending the headphones back and looking for a more suitable replacement from a manufacturer with a stronger reputation.
