4. Stowing the Earbuds
When not in use, the PI5 earbuds should be
stored inside the charging case where they will be
recharged ready for future use.

charged and may be used immediately. For best
practice we recommend fully charging the earbuds
before first use. Please allow up to 3 hours for full
charge.
