Which has better battery life?

The Soundcore Space A40. It offers up to 50 hours total with the case, versus 15 hours for the Sony WF-C700N.

Is the Sony worth the extra money?

Only if you want Sony sound and 360 Reality Audio. Otherwise the Anker is cheaper and lasts much longer.

Which is better for calls and switching devices?

The Anker, because it supports multipoint pairing for two devices. The Sony listing does not mention multipoint.

Can I use either in the rain?

Yes, both are rated IPX4, which handles sweat and light rain but not submersion.

Which is better for small ears?

The Sony WF-C700N, with its smaller 5 mm drivers and compact in-ear design.

Which charges faster?

The Anker. A 10-minute charge gives up to 4 hours, versus 1 hour for the Sony.
