specifications of acoustic-mechanical gain at 1.6 kHz and 60 dB SPL

Abutment-free hearing with no sacrifice in performance.1

Now with a peak output of 115 dB, the Sophono Alpha 2 MPO gives your patients uncompromised sound with four programs, eight channels, and up to 320 hours battery life.2

Compared with other transcutaneous hearing systems:

§ Up to 7dB more feedback free gain compared to other transcutaneous devices.3

§ Sophono has the lowest processor profile, a sleek solution that may be hidden under the hair.

The Alpha 2 MPO magnetic bone conduction system features a titanium encased magnetic implant, an external processor, and Attract® magnetic spacers with variable strength to ensure patient comfort and secure fit.

All Sophono products are specifically designed for amplification of sound force through the skin into the bone. We call this Transcutaneous Energy Transfer (TET™).

No other implant system - abutment or magnetic, offers the low profile and stability of the Sophono device.

Compared with other transcutaneous hearing systems:

§ Sophono boasts the smallest implant on the market (2.6 mm high).1

§ The implant is secure to the bone with 5 screws making it less likely to break, come loose or fall out during an impact.2

§ Our low profile implant follows the contour of the skull, ensuring a snug fit against the bone, resulting in a safer bone conduction implant.5

§ MRI compatible up to 3 Tesla and the smallest transcutaneous MRI shadow.3
