Before choosing
When it may fit
They may suit a compact in-ear fit when switching between a phone and another device. Multipoint maintains two Bluetooth connections and switches sources according to operating conditions. Ambient Sound Mode brings external sound into listening; tip fit affects retention and passive isolation.
Limits
They do not feature active noise cancellation: Ambient Sound Mode is not ANC or a guarantee of hearing every surrounding warning. IPX4 applies to the earbuds, not the case; it does not permit immersion, swimming or charging wet components. Battery life depends on volume, features, calls and operating conditions; we have not physically tested battery life, sound, microphones or comfort. DSEE is a processing feature, not a guarantee of restoring a lossless recording.
Check before buying
Confirm WF-C510 in black, with both earbuds, case and correctly sized tips. Sony does not list a USB-C cable in the US package; check whether you need to buy one. Check charging accessories and current Sony app requirements before relying on customization. Check multipoint operation with your two devices and choose a responsible listening volume. Dry components following the manual before storing or charging them. Confirm seller, condition, price, delivery and returns on Amazon.
