Review on Experience Ultimate Freedom 🎧 with Sony WI XB400 Wireless Headphones by BU Jang ᠌

I use 1-3 hours a day to listen to books on bluetooth from my phone. Completely satisfied, no complaints. I tried (for a long time) models 200, 300, 400 - there is a slight increase in quality with an increase in the model (and, accordingly, the price). The 400 series has more low frequencies, the sound is the most natural. For books, you can take any, but I chose the 400th. As for music, I can't say, mainly because everyone has their own requirements. If there are no big expectations and claims (mp3 from the phone via bluetooth), then they are quite suitable.
