Dual LED displays clearly show the remaining battery for both bluetooth earphones and case. With USB-C fast charging, a full recharge takes just 1.5 hours, making it ideal for busy workdays, evening study sessions, or long creative projects, reducing the need for frequent charging!

Precision Ergonomic Fit for Extended Wear and Active Lifestyles: Each earbuds wireless bluetooth weigh only 4 grams and features a precision-engineered in-ear ergonomic design that balances stability and long-term comfort. With IP7-rated sweat and moisture resistance, they perform reliably across running, fitness routines, extended outdoor excursions, and daily on-the-go activities, minimizing the need for adjustment and enhancing user focus during sustained use.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $3 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Csasan products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
