Neckband is the best formfactor really - no need to carry around any charging case, no wired connection to phone, but decent battery life and earbuds are not bulky. Unfortunately it will not have enough attention without Apple releasing something similar..
CMF Neckband Pro have landed in India with a launch price of INR 1,999 (around $24). These new headphones from the Nothing sub-brand bring 50 dB hybrid ANC, 37 hours of total runtime, 5 microphones for clear calls, and spatial audio support for immersive listening.
