Splenssy Bone Conduction Bluetooth Mini Speaker

Splenssy's mini bone conduction Bluetooth speaker is a compact wireless sound box that turns surfaces into powerful stereo sources with deep bass and hands-free calling.

This pocket-sized device uses bone conduction technology to transmit sound vibrations through contact with surfaces, letting you create room-filling audio from plastic, glass, wood or metal objects. With Bluetooth 5.0, True-WS stereo pairing, up to 115 dB peak output and a 400 mAh battery, it’s designed for travel, home use, and outdoor activities where portability and flexible placement matter most.

How does bone conduction change the way I listen?

Rather than projecting sound into open air like a traditional speaker, this unit vibrates the surface it sits on to produce audio. That makes playback louder and richer when placed on resonant materials, and lets you experiment with different textures to tune the tone.

• Transforms ordinary surfaces into resonant speaker panels for fuller sound.
• Produces clearer lows and trebles when placed on wood, glass, or hard plastics.
• Useful in settings where traditional speakers are impractical or fragile.

What connectivity and battery performance can I expect?

The speaker supports Bluetooth 5.0 for fast, stable pairing and includes True-WS capability for wireless stereo linking with a second unit. A built-in 400 mAh lithium battery delivers about six hours of playback from a one-hour charge, making it convenient for short outings and daily use.

• Bluetooth 5.0 ensures reliable wireless range and low latency.
• True-WS enables left-right stereo when paired with another Splenssy unit.
• 400 mAh battery gives up to 6 hours playback after roughly a 1-hour charge.

How loud and clear is the sound for different uses?

With peak output up to roughly 115 dB, the speaker can reach high volumes suitable for small gatherings or outdoor listening. Tone clarity and bass depth depend on the surface chosen — denser, stiffer materials yield better low-frequency response and more pronounced treble.

• High maximum volume for backyard or picnic scenarios.
• Best bass on wooden or hollow surfaces; glass provides brighter highs.
• Built-in microphone supports hands-free phone calls and voice interactions.

How small is it and how portable for everyday carry?

The Splenssy mini speaker is deliberately compact and lightweight so it fits into a bag or pocket and doubles as a decorative object when not in use. Its simple controls and quick charge time make it practical for commuting, travel, or moving from room to room.

• Miniature footprint ideal for backpacks, purses, or desk use.
• Durable construction suited for outdoor and travel conditions.
• Quick charging — approximately one hour to full battery.

Who is this for: The Splenssy bone conduction mini speaker is made for listeners who value portability and experimentation with sound — travelers, apartment dwellers, content creators, and anyone who wants a versatile, hands-free audio solution that turns everyday surfaces into a speaker. It’s also a good fit for people who want a compact device with strong output and simple Bluetooth stereo pairing.
