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 Micha Dziubiski ᠌

The advantages include having a good sound, both bass and treble, having everything in its proper spot, the whistle being easily connected to the computer by bluetooth, the iPhone being easily located, being very convenient without wires, and having an adequate amount of battery life. The constant background noise is the most significant disadvantage, but some people are oblivious to it. There is still a problem with the lack of a clothespin because the ears still try to escape when only one is inserted. It is unclear why the ear pads are packaged as a set consisting of a single piece that has a variety of sizes.
