Absolutely! EssiHear includes 32GB local memory storage, allowing you to load thousands of songs directly onto the headphones. This feature is perfect for swimming when you can't bring your phone underwater.

Yes, the lightweight 25.8g design and soft rubber ear hooks fit comfortably alongside glasses. The Golden Triangle ear hook design distributes pressure evenly without creating uncomfortable pinch points behind your ears.

Simply rinse EssiHear headphones with fresh water after pool use and dry with a soft cloth. The IP68 waterproof construction protects internal components, making maintenance effortless while preserving long-term durability.

Bluetooth signals don't penetrate water effectively, so use the 32GB built-in storage for swimming. Above water, Bluetooth 5.4 provides stable 10m range connectivity with low latency for all your devices.
