Review on Sony - C400 Wireless Behind-Neck In Ear Headphone White (WIC400/W) by Aashit Sharma ᠌

I'm really happy with the headphones because they are just what I was hoping for—headphones that can run continuously for 10 to 12 hours! At work, I listen to books; the headphones don't need to be recharged for two days. Sadly, the wires have become much more inflexible, although these are minor inconveniences. The tingly wires simply ruptured in the headphones, which are a year old and that I got for my wife and me so that we could both use one "ear" while working. charge still sufficient
