The sound quality of this product has also received a lot of comments online. My personal feeling: very satisfied with the five-star praise. HD audio decoding is very suitable for video and audio entertainment. The tri band is balanced. Although it is a virtual 7.1 channel of 2 units, the surround and stereo sense are excellent, and the positioning is also very accurate when playing games (it is a small pity that there is no microphone). Of course, the so-called "pop house" feeling cannot be expected to compare with high-end home theaters, but it will not be noisy. Don't worry about the neighborhood committee aunt checking the water meter. When listening to music, I think it is at least as good as my partner's AKG K450, and I have never heard of more advanced music
