Device compatibility

S2/S3 uses Bluetooth version 5.3 which is compatible with a wide range of Bluetooth devices. The paired device does not need to be the same version, but similar versions are more likely to maintain a strong connection. 

Signal interference

Some wireless devices may interfere with each others' signals, such as WiFi-routers, smartwatches, other Bluetooth devices, etc. If they operate within the same frequency, you may experience interference such as dropped sound and glitching. The easiest way to locate the cause of interference is by maintaining one connection between devices at the same time or moving your S2/S3 and connected device away (outdoors or to a different room) to see if the interference clears.

S2/S3 can be up to a maximum of 10 meters (32 ft) from the paired device, but the connection may break if they are blocked by walls or similar objects.

S2/S3 is a device with a level 5 water protection rating, which means that the speaker is water-resistant. At this level, the speaker can handle exposure to low-pressure water jet spray. IPX is an official rating that is awarded by an assessment conducted by a third party organization.

IPX5 water protecting allows you to enjoy music in the shower, kitchen or even outdoors.
