Currently, we do not support Bluetooth headphones. With a wireless connection, there is always a risk of slight audio delays. If the metronome or the accompaniment music is played back with a slight time delay, this will have a negative effect on the rhythm result. For this reason, we recommend using wired headphones.
If you do not have a headphone jack, we recommend using a headphone jack adapter so that you can use tonestro with wired headphones.
