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

Conveniently located on the neck, do not interfere under clothing. They work for a very long time without recharging, they have never been discharged to the end during the week, although I listen 1-2 times a day for an hour. High-quality, natural, clean, properly balanced sound (I compare it with JBL T110 BT - in the latter the sound is muffled, there is a lot of bass). Convenient control buttons. Normal indication - flashes periodically, not too bright, does not annoy anyone. It pairs quickly with a smartphone, keeps a good connection, good sound when used as a headset, the interlocutor is also well heard.
