switch.sh

#!/bin/bash

# Get the name of the Bluetooth headset
device_name=$(pactl list cards | grep -B 20 "device.form_factor = \"headset\"" | grep "Name" | awk '{print $2}')

# Get the current active profile for the headset
active_profile=$(pactl list cards | grep -A 40 "Name: $device_name" | grep "Active Profile" | cut -d ' ' -f3)

# Toggle between the two profiles
# Complete list of available profiles can be seen by using pactl list cards
if [ "$active_profile" == "a2dp-sink" ]; then
    pactl set-card-profile "$device_name" headset-head-unit-msbc
    echo "Switched to HSP"
else
    pactl set-card-profile "$device_name" a2dp-sink
    echo "Switched to A2DP"

This assumes you're using BlueZ and pulseaudio (or pipewire-pulse)

If your headset doesn't have the same profiles, then you'll need to modify the script by using information from pactl list cards.
