Splenssy Bone Conduction Mini Bluetooth Speaker

Splenssy's bone conduction mini speaker is a pocket-sized Bluetooth soundbox that turns surfaces into resonant speakers for loud, bass-rich audio and hands-free calls.

This compact wireless speaker uses bone conduction technology to transmit sound through contact with surfaces, creating varied audio textures depending on what it touches. With Bluetooth 5.0 and True Wireless Stereo support, a 400mAh battery, and a built-in microphone, it’s designed for on-the-go listening, small gatherings, and creative DIY sound experiments. The unit reaches high volumes and emphasizes full bass and clear treble for a surprising output given its mini size.

How does the Splenssy bone conduction speaker change ordinary surfaces into speakers?

Instead of relying on a traditional cone, this speaker vibrates when placed on solid objects, turning those objects into sound radiators. Different materials and shapes produce distinct tonal qualities, allowing you to tailor the sound to your environment.

• Place on glass for brighter treble and more shimmer.
• Place on wood for warmer mids and fuller bass response.
• Try plastic or metal for punchier, louder output.
• Adjust placement and contact pressure to fine-tune resonance.

What wireless features and connectivity can I expect?

The speaker includes an advanced Bluetooth 5.0 chip for stable pairing with phones, tablets, and laptops, and it supports True Wireless Stereo for pairing two units into a left/right stereo pair. Setup is simple and fast, with automatic reconnection once paired.

• Bluetooth 5.0 for lower latency and reliable range.
• True Wireless Stereo (TWS) for stereo separation when using two speakers.
• Built-in microphone for hands-free calls and voice interactions.
• Quick pairing and one-hour full charge time.

How long does the battery last and how loud will it play?

The internal 400mAh lithium battery delivers up to about six hours of playback on a full charge depending on volume and usage patterns. The speaker is rated to reach high volumes—suitable for small rooms and outdoor casual gatherings—while retaining clear bass and treble balance.

• 400mAh battery with approximately 6 hours typical playtime.
