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

Really good headphones all around. The Sony MDR-XB50AP sounds quite similar to this, except it has far worse sound isolation. Occasionally, turning on the XB50AP to block out noise was sufficient; but, in situations like these, music must be played. In regards to the microphone, you can clearly hear me at home; but, on the street, when the rim is hidden by a jacket, it is audible but not clearly enough. Also, a peculiar quirk is that when your headphones are in headset mode, the sound coming from the microphone is also sent to your ears.
