Designed for Companion30 Speaker

This silicone sleeve is made specifically for the Companion30 wireless speaker. It wraps the device in a durable silicone layer that shields against impacts and drops. The cover adds protection without increasing the overall size of the speaker. It is a dedicated accessory for owners of that model.

Slips on without blocking ports

The sleeve fits tightly around the speaker body while leaving the charging port and controls fully accessible. No tools or adhesives are required for installation. It adds a sweatproof barrier for outdoor or active use. The speaker remains fully functional while inside the case.

Silicone holds up to daily knocks

The 440 x 45 mm silicone shell absorbs repeated bumps and scrapes without cracking. Its flexible structure returns to shape after being stretched over the speaker. The material resists sweat and minor moisture during extended sessions. It maintains its protective qualities over long periods of handling.

Questions about this item

Will the sleeve stretch or lose grip after months of daily use?

The 1.7 mm thick silicone sleeve is moulded to the Companion30 dimensions and retains its elasticity, so it continues to hug the speaker without loosening over time.

Does the silicone trap heat against the speaker during long playback sessions?

Silicone is a low-conductivity material; the open-bottom design leaves the speaker’s own vents exposed, allowing normal airflow while the sleeve is fitted.

Which speaker model must I already own for this sleeve to fit?

The sleeve is sized at 440 x 45 mm and cut specifically for the Companion30 Bluetooth speaker; it will not fit other models.
