Iqoo has yet not entered the Tws market in India. If it hopes to compete against the likes of Realme and OnePlus which dominate the under 5000 Tws department it must offer : -

LDAC support 

40 hours or more battery life with case

40db or higher ANC

Atleast 11mm single or dual driver

Bluetooth 5.3 or higher

Google fast pair.

Dedicated app support.

Will wait and see how the brand tackles this.
