The audio quality is device-specific. When paired with a computer and Windows Sonic Spatial Sound enabled (I believe also with dolby access), headphones produce excellent sound quality; however, when used with a mobile device, the volume is insufficient and the quality of the sound is diminished, preventing me from adjusting the equalizer settings. There are benefits: Battery. I didn't time how long I listened to music, but the battery lasted around two weeks. Many drawbacks: These appear quite cheap, like a knockoff made in China. Nothing came loose, fell off, or broke for a full six months. They are more formidable than they look.
