Bone Conduction Headphones Bluetooth 5.3 - Open-Ear Sport Headphones

Our review of the LOBKIN X7 bone conduction headphones finds they are best for active users who want to listen to music and take calls while staying aware of their surroundings. The single biggest reason to buy is the combination of true open-ear bone conduction playback with a built-in 32GB MP3 player and IP68 waterproofing, which together let swimmers and runners use the same headset for Bluetooth streaming or offline playback without blocking the ear canal. The lightweight 27g frame and silicone outer layer keep the headset stable in motion while preserving situational awareness.

Key Features

• Bone conduction technology: Delivers audio through the cheekbones so users can hear music while keeping their ears open to ambient sound for safety.
• 32GB internal memory: Lets users load MP3, FLAC, APE, WMA and WAV files and play music directly from the headset when swimming or without a phone.
• IP68 waterproof rating: Rated for use up to 3 meters, the headset can be used in pools and resists sweat and seawater corrosion for consistent outdoor durability.
• Bluetooth 5.3 and mic: Provides stable wireless connectivity, improved transfer speed and clear calls with the bi-directional microphone.
• Lightweight, open-ear design: At about 27g with a balanced center of gravity and non-slip silicone, the X7 stays comfortable and secure during intense workouts.
• Battery life: The 180mAh battery provides around 6 hours of continuous use, enough for extended training sessions.

Who It's For

The X7 is ideal for runners, cyclists and swimmers who need to stay aware of traffic and surroundings while listening to music or taking calls, and for athletes who want an underwater MP3 player without separate gear. It also suits anyone who dislikes in-ear isolation but wants better audio than typical bone conduction prototypes.

People who prioritize the absolute best in-ear noise isolation or long continuous play beyond roughly 6 hours should consider other designs. Audiophiles seeking deep bass and closed-back isolation will also want a different headphone type.

Pros & Cons
