Review on Sony WI-XB400 Wireless In-Ear Extra Bass Headset/Headphones with Mic: Blue (WIXB400/L) – Experience Enhanced Phone Calls and Music Quality! by Mateusz Banasiuk ᠌

The sound quality is remarkable, especially considering the low cost of the product. I listen to it at medium volume, and if I use it for seven hours a day, the charge will last me two days if I listen to it for that long each day. It is difficult to estimate how long the charge will hold because the volume is so high when it is turned all the way up. And the charge continues to stand. Cons: The wire, as was previously indicated, becomes more rigid when exposed to cold temperatures. Let's see how well it holds up against the frost. The staggered charging of the battery (100%, 70%, 50%, and 20%) that could be done at least after 10 was something I did not like for.
