Quick aid / Quick aid QA-509K Dry case for earphones

Dry case for earphones Quick Aid QA-509K is a dry case specially designed for earphones to enjoy ‘good sound’ for a long time. High-performance composite desiccant protects earphones from moisture and condensation. It reduces sound quality degradation and malfunctions and prolongs the life of your valuable earphones. The compact and shock-resistant case is also attractive.

■ Triple effect with high-performance composite desiccant
- This product uses a high-performance composite desiccant that provides three effects: drying, sterilisation and deodorisation. It powerfully removes moisture such as sweat, humidity and condensation, which can cause earphones to malfunction and deteriorate sound quality. Furthermore, the sterilising and deodorising effects keep the earphones clean and prevent unpleasant odours. This allows the earphones to be used at any time with comfortable sound quality.

■Simple and easy storage, stress reduction
- When you have finished using the earphones, simply put them in the case and close the lid to complete dry storage. No complicated settings or power supply is required, reducing the stress of storage in everyday use. Proper management after use is easy, so the earphones can be kept in good condition at all times.

■Rigid housing for shock resistance and safety
- The earphones have an extremely robust housing design to protect them from shocks in the event of accidental impact during transportation or storage. By protecting your valuable earphones, custom IEMs and other precision equipment from the inside and outside, the risk of malfunction due to unexpected accidents is greatly reduced, allowing you to use and store them with peace of mind.

The standard replacement period for the desiccant is approximately 2-3 months.
