Review on Sony WIC400/L Wireless Behind-Neck In-Ear Headphones, Blue by Athit Nivongsa ᠌

Overall, very good headphones. The sound is very similar to the Sony MDR-XB50AP, but the sound isolation is very poor compared to them. Sometimes I put on the XB50AP just to reduce external noise and that was enough, but in these you have to turn on the music. About the microphone - at home you can hear me very well, on the street when the rim is under the jacket, it's audible but badly enough. Plus, a strange nuance, when the headphones work in headset mode, the sound from the microphone is also transmitted to your headphones.
