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 Komorowski ᠌

The sound quality of the XB-400 isn't terrible, but it is clearly lower quality than the sound produced by my cable MDR-EX650AP. Below are some advantages: As a replacement, I decided to get an MDR-EX650AP because the cable broke at that location and the microphone ceased functioning. I hoped that the wireless connection would be more long-lasting than the wired one. The microphone performed admirably, but there was some background noise that made it difficult for the other person to hear what was being said. Battery life and operating range, with a thud. They instantly link to a computer or smartphone, but you have to switch manually between the two devices. Got cons: When I initially opened it, my initial reaction was one of mild displeasure because the plastic components that dangled down turned out to be significantly larger than they appeared in the photographs. Although there have not been any complaints regarding the build quality as of yet, the plastic that these pieces are made of has a cheap feel to it and may not be very robust.
