Sony WH-CH520 are lightweight wireless on-ear headphones designed for music, calls and everyday entertainment. Their long battery life and compact design make them especially practical for seafarers during travel, shore leave and long contracts at sea.
The headphones deliver up to 50 hours of battery life, while USB-C quick charging provides up to 90 minutes of playback from just 3 minutes of charging. Sony’s DSEE technology helps restore detail lost in compressed audio, and the Sony Sound Connect app provides adjustable EQ settings for personalised sound.
A built-in microphone supports hands-free calls and online meetings, while Bluetooth 5.2 and Multipoint Connection allow the headphones to stay paired with two compatible devices simultaneously. The adjustable headband, soft ear pads and lightweight construction are designed for comfortable extended listening. Note that the WH-CH520 do not feature active noise cancellation and cannot be used with an analogue audio cable.
