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

The music sounds fantastic. Sony, in a word. Sounds fantastic without any equalization settings, but can be rustled up with a little effort. The instructions indicate the headphones will warm up and produce more bass after a while, but I find the sound satisfactory right away. To be quite frank, the treble and midrange are more apparent than the bass, but otherwise, the earphones provide a serviceable listening experience. On the second wearing, the collar forgot it even existed. The buttons are so well designed that you don't even need a tambourine to press them. In terms of the "hands free," "no wires," and "danger of losing the earphone" trilemma, the design itself is great. In my opinion, the best feature of this model is the convenience of being able to take out and toss the earpiece, although this is a benefit of the circuit in general. There is no delay, no connection loss, and no interference. The workday is also 10 hours long. Look great peeking out from behind the collar of the shirt. The Length Can Be Modified As Needed
