I've been able to reproduce this exact issue very easily on the
bluetooth Parrot Zik and Parrot Zik 2 models with my btusb receiver by
running out of range of the receiver.
When out of range, a popping sound can be heard while the sound cuts
for a few milliseconds, and the sound then resumes where it initially
left off, creating a latency buffer which keeps growing every time the
headset goes out of range again.
The buffer resets when the card profile is turned off and back on (eg.
pactl set-card-profile bluez_card.... off && pactl set-card-profile
bluez_card.... a2dp_sink).

Worth noting the issue does not happen on the Parrot Zik 3, which is
compatible with Bluetooth 4.x (unlike the versions 1 and 2).
