1MORE S50 Fit Open Earbuds-FAQs
What are the main features of the 1MORE S50 Fit Open Earbuds?
The 1MORE S50 Fit Open Earbuds are premium open-ear sports earbuds designed for comfort and awareness. They feature a PurePower dual-magnetic driver with a diamond-like carbon diaphragm for improved audio clarity and power. With Bluetooth 5.3, AI-powered ENC for calls, wireless charging, and up to 38 hours of total battery life, they are built for both daily use and active lifestyles.
Are the 1MORE S50 earbuds waterproof and suitable for workouts?
Yes, these earbuds come with an IPX7 water resistance rating, meaning they can handle sweat, rain, and even brief water exposure. This makes them highly suitable for intense workouts, running, and outdoor activities. However, the charging case itself is not water-resistant, so it should be kept dry to avoid damage.
How long does the battery last on the 1MORE S50?
The earbuds offer approximately 11 hours of playback on a single charge, with the charging case extending total battery life to around 38 hours. They also support fast charging, where a quick 5-minute charge can provide about 2 hours of listening time. This makes them reliable for long sessions without frequent recharging.
How is the sound quality of the 1MORE S50 open earbuds?
The S50 delivers well-balanced and detailed sound thanks to its PurePower driver and DLC diaphragm. It is tuned by a Grammy-winning engineer for a natural listening experience. While open-ear designs don’t isolate sound like in-ear models, these earbuds still provide strong bass and clear audio suitable for workouts and casual listening.
Do the 1MORE S50 earbuds have active noise cancellation?
No, the S50 does not include active noise cancellation because of its open-ear design, which prioritizes environmental awareness. However, it features AI-powered environmental noise cancellation for calls, using multiple microphones to reduce background noise and improve voice clarity during conversations.
Are the 1MORE S50 earbuds comfortable for long use?
Yes, they are designed for extended wear with a lightweight 10g per earbud build and ergonomic ear hooks made from memory wire. The open-ear design prevents pressure in the ear canal, making them comfortable for long listening sessions, especially during workouts or outdoor use.
Is the fit secure during exercise?
The earbuds use ear hooks and “sound loops” to stay in place, offering a generally stable fit for moderate activity. However, some reviews note that the fit may not be ideal for everyone, especially during intense workouts or for users wearing glasses. Fit can vary depending on ear shape and personal comfort preferences.
How does the open-ear design benefit users?
The open-ear design allows you to hear your surroundings while listening to audio, improving safety during activities like running or cycling. It uses air conduction technology to deliver sound without blocking the ear canal, making it a great option for outdoor and fitness-focused users.
Do the 1MORE S50 earbuds support wireless charging and modern connectivity?
Yes, the S50 supports wireless charging, making it convenient to power up without cables. It also features Bluetooth 5.3 for stable connectivity, reduced latency, and better energy efficiency. These features enhance usability across different devices and everyday scenarios.
Are the 1MORE S50 Fit Open Earbuds worth buying?
The 1MORE S50 is a strong choice for users who prioritize comfort, awareness, and battery life in an open-ear design. They offer solid sound quality, durable water resistance, and modern features like wireless charging. However, they may not suit users who need strong noise isolation or a very secure fit for high-intensity workouts.
