With Qualcomm apt-X HD audio decoding, they reproduce richer, more detailed audio. The open-ear design follows ergonomic principles, avoiding a tight seal in the ear canal for all-day comfort.

【Comfortable and Secure Fit for All Day Use】Monster open ear earbuds are thinner, lighter, more comfortable and more secure than other types of headphones, ensuring pain-free all-day wear. The Bluetooth headphones are made of an innovative shape-memory hardshell material that maintains a secure fit no matter how long you wear them.

【21H Long Playtime and Fast Charge】Monster open ear headphones deliver up to 7 hours of playtime on a single charge (at 50-60% volume). The compact charging case provides 21 hours of total battery life, keeping your music going nonstop. Featuring USB-C fast charging, just 10 minutes of charging gives you 1 hour of playback—so you can power up quickly and get back to your day.

【IPX6 Water Resistant for Outdoor Use】Engineered for active users, Monster Wireless headphones feature sweat-proof and water-resistant protection, making them durable enough for any challenging conditions.

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 $56 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 Monster 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.
