As there is no wire involved in true wireless earbuds, it is very important that they stick in your ears comfortably. Look for nice ergonomically designed earphones that snug inside your ears. If you are going to use them for calling, then look for ear buds that also support ANC. Bluetooth 5.0 is fast becoming the standard of this technology, and many manufacturers have started offering a low latency mode. Some earbuds even support voice assistants. The controls can either be touch or press based but you can manage your calls, adjust the volume and take care of your playlist by simply moving your hand to your ears.
