The Shokz OpenRun Pro 2 headphones can generally be connected to Garmin watches, but there are a few points to consider to ensure an interference-free Bluetooth connection.

## Compatibility
- The OpenRun Pro 2 headphones support Bluetooth 5.1, which offers good compatibility with most modern devices, including Garmin watches.

## Pairing process
- To pair the headphones with a Garmin watch, pairing mode must be activated by pressing and holding the Volume+ button for 5-7 seconds until the LED light flashes red and blue. The Bluetooth settings of the Garmin watch must then be opened and the headphones selected.

## Interference-free connection
- Connection problems may occur with some devices, including some Garmin models. This may be caused by the specific Bluetooth version of the device or by interference with other Bluetooth devices in the vicinity. It is advisable to switch off other Bluetooth devices in the vicinity and perform the pairing process again to ensure a stable connection.

## Multipoint pairing
- The OpenRun Pro 2 support multipoint pairing, which makes it possible to be connected to two devices at the same time. However, this can affect the stability of the connection if both devices are within range.

In general, the Shokz OpenRun Pro 2 should connect to a Garmin watch without any problems, but it is important to follow the pairing instructions carefully and minimise any interference.
