Good quality waterproof headphones with in-the-ear design, made with a standard 3.5mm plug. Great sound above and below the waterline. Headphones have been tested to a depth of 10m/30ft - but they are not suitable for use at depths greater than 10ft/3m where pressure may cause hearing damage. Comes with spare ear buds and Headphone Buoy to store headphones when not in use. The perfect accessory for use with Aquapac MP3 Player case.
