Splenssy Bone Conduction Mini Bluetooth Speaker in Mic

Splenssy's mini bone conduction Bluetooth speaker converts surfaces into powerful, portable sound sources for compact, hands-free listening.

This compact wireless speaker uses bone conduction technology to transmit vibrations through objects, turning desks, boxes, glass, or wood into resonant speakers. With Bluetooth 5.0 connectivity, True Wireless Stereo support, and a built-in microphone, it pairs easily with phones and tablets for calls and music. Its small footprint and up to six hours of playback make it a travel-friendly option for desk work, outdoor leisure, and creative audio experiments.

How does bone conduction change the way music sounds?

Bone conduction delivers audio as vibrations that travel through surfaces rather than relying solely on air-based speaker drivers. That means the sound character depends on the object you place the unit on, offering a range of tonal results from enhanced bass on dense surfaces to brighter treble on glass.

• Converts tables, boxes, and glass into resonant soundboards.
• Creates various timbres — fuller bass on wood or plastics, clearer highs on glass.
• Good option for creative demos, ambient background audio, and compact setups.

How reliable is the wireless connection and battery life?

The speaker uses a BT 5.0 chip for stable pairing and lower latency with compatible devices. It also supports True Wireless Stereo, letting two units form a left-right pair for wider soundstage. The internal 400 mAh battery charges quickly and supports up to around six hours of continuous playback from a full charge.

• Bluetooth 5.0 for improved range and fewer dropouts.
• True Wireless Stereo for stereo separation using two units.
• 400 mAh battery delivers approximately 6 hours playtime after about 1 hour charging.

What sound performance can I expect from such a small device?

Despite its mini size, the speaker is engineered for loud output and a balanced profile, reaching high decibel levels while preserving bass presence and clear treble. The bone conduction method emphasizes low-frequency energy differently than conventional speakers, so you’ll notice richer vibration-driven bass on solid surfaces.

• High maximum volume — designed for up to 115 dB peak output in ideal conditions.
• Full bass response on dense surfaces and pronounced treble on smooth materials.
• Built-in microphone for hands-free calling and voice pickup.

Who is this for? The Splenssy mini bone conduction Bluetooth speaker suits listeners who want a small, inventive audio solution for travel, desk setups, or outdoor gatherings. It's aimed at people who enjoy experimenting with sound, need a compact speaker for calls and music, or want a decorative, portable audio device that doesn't occupy much space. Ideal for commuters, creatives, students, and anyone seeking a unique way to amplify audio using everyday surfaces.
