Headphones are made very high quality like all ugreen products. In the ears sit comfortably and do not interfere with long-term use. Sound quality, better than Samsung Galaxy buds pro. If you install a proprietary application, you can switch noise reduction and end-to-end sound, and there are many other settings. In general, I liked the headphones very much, I can't say anything about autonomy yet, in the process of testing. Arrived quickly in 10 days.
