Open-Ear Headphone Wireless Bluetooth S31 - Comfortable 30H Playtime

Our review of the 1MORE S31 open-ear headphones finds a clear niche: people who want safe, comfortable listening during activity without isolating themselves. The biggest reason to buy is the combination of an open-ear design with a long battery life, letting users stay aware of their surroundings while still getting punchy, balanced audio for runs, rides, and gym sessions. The S31s trade passive isolation for all-day wearability and stable fit, and that tradeoff is exactly what many outdoor exercisers and commuters will appreciate.

Key Features

• Open-ear design: Lets you hear ambient sounds for safer outdoor use while delivering clear music and calls without in-ear pressure.
• Gravity-balanced ear hooks: Memory wire and soft silicone conform to the ear for a secure fit that stays in place during movement.
• 14.2 mm dynamic driver: Provides a rich, well-balanced sound with enhanced bass using the DBB algorithm for more satisfying low end.
• 30H playtime: Extended battery life supports long workouts and multi-day use between charges.
• IPX5 water resistance: Protects against sweat and rain so you can use them while training in varied conditions.
• Four EQ presets in app: Simple personalization for different music types without complicated setup.

Who It's For

The S31 is aimed at runners, cyclists, and active commuters who need situational awareness and comfort for long sessions. If you want to hear traffic and conversation while listening to music, the open-ear layout is a practical choice.

These are less suitable for users who require full noise isolation or maximum bass presence in quiet indoor listening; audiophiles who prefer closed-back cans or in-ear isolation will want to look elsewhere.

Pros & Cons

Pros

• Very comfortable for long wear thanks to slim, lightweight construction and memory-wire ear hooks.
• Stable fit that holds during runs and workouts without pinching or clipping.
• Balanced sound with clear mids and boosted bass from the DBB algorithm.
• Long battery life and IPX5 rating make them reliable for outdoor use.

Cons

• Open-ear format limits passive noise isolation, so bass and immersion are reduced compared with in-ear models.
• Those seeking complete sound privacy or studio-level isolation may find the design unsuitable.
