1MORE S20 Feature Overview
Open-Ear Awareness: Music can be enjoyed without blocking the ears, allowing users to remain aware of conversations, traffic, announcements, and other sounds around them. That makes the S20 Ultra well suited for commuting, outdoor walks, workouts, and everyday use.
Ultra-Light Comfort: Each 1MORE S20 Ultra earbud weighs just 5.5 grams. The company’s Balance AIR+ 3.0 design uses an ergonomic layout and balanced weight distribution to reduce pressure on the ear. Breathable, skin-friendly materials are intended to improve comfort during extended listening sessions.
Adaptive Secure Fit: The S20 Ultra uses flexible memory titanium C-rings designed to conform more naturally to different ear shapes. The clip-on design aims to reduce pinching and fatigue while maintaining a secure fit during workouts, commuting, work, and other daily activities.
All-Day Battery Life & IP66 Rating: The S20 Ultra provides up to 8.5 hours of playback per charge and up to 40 hours total with the charging case when SuperBass 3.0 is enabled. The earbuds are also IP66-rated for resistance to sweat, rain, dust, and splashes.
Audio Support: The 1MORE S20 Ultra features Bluetooth 6.0 with Hi-Res Audio support and the LDAC codec. Custom 11 mm triple magnet drivers use four layer diaphragms and support SuperBass 3.0.
BISA spatial audio is designed to create a more expansive, layered soundstage, while SDT 2.0 directional sound technology directs more of the audio toward the listener’s ears to reduce sound leakage.
1MORE App: The 1MORE App for iOS and Android provides access to six preset EQ modes, a low latency gaming mode, Find Headphones, and additional settings and controls.
Clear Calls: The S20 Ultra uses four directional beamforming microphones with AI noise reduction to help isolate the user’s voice while reducing wind and surrounding noise. The system is designed to improve call clarity and stability in noisy environments, including during running, cycling, commuting, and outdoor work.

The Bottom Line
The 1MORE S20 Ultra arrives at exactly the right time. Clip-on earbuds have quickly become one of the more interesting parts of the wireless market because they offer something conventional TWS models cannot: music without sealing off your ears from everything happening around you.
At $79.99, the S20 Ultra also offers a lot for the money. Bluetooth 6.0, LDAC, spatial audio, up to 40 hours of total battery life, an IP66 rating, and four microphone calling support make this more than just another inexpensive open ear option. The 5.5 gram design puts comfort at the center of the experience, while 1MORE’s SDT 2.0 directional sound technology attempts to address one of the category’s biggest weaknesses by directing more of the sound toward your ears and reducing leakage.
There is plenty of competition. The SOUNDPEATS Clip1 sells for $69.99, while the newer UU2 comes in at just $49.99 and also offers Bluetooth 6.0 and LDAC. At the other end of the category, the Shokz OpenDots ONE costs $199. That puts the S20 Ultra in an interesting middle ground for listeners who want more features than the least expensive clip on models without spending $200.
Who is it for? Commuters, runners, cyclists, office workers, and anyone who dislikes having conventional earbuds pushed into their ear canals but still wants better codec support and useful app features. The S20 Ultra does not reinvent the category, but for less than $80, 1MORE has assembled a rather compelling package in one of the fastest growing segments of the wireless earbud market.
