I have the these 'tantra groove' headphones . Rs 1800 . behind the neck. on the ear. *www.amazon.in/Tantra-Folding-Bluetooth-Wireless-Headphone/dp/B01I1K77A6
Bought 2.5 years ago. The one now sold have been upgraded. So some things may have changed.
Pro: amazing battery life. Good enough sound for me ( I don't know much about sound). 5 Buttons on headphones come incredibly handy +- vol , play/pause next/prev
Con: mic was meh.
Is behind the neck design is not ideal when lying down and depends a lot on personal preference. It Can be used for lying down though, adjust the pillow or move about a bit
. I would suggest trying a similar headphone to know if behind the neck design works for you.
