Pacemaker manufacturers recommend that a minimum

pacemaker to prevent potential interference with the
pacemaker. If using a pacemaker, hold the device on the

listen at high volume levels for long periods.

Using a headset at high volumes may damage your
hearing. To reduce this risk, lower the headset volume to
a safe and comfortable level.

Do not store or transport the device in containers with
flammable liquids, gases, or explosives.
