Sophono™ Alpha 2 MPO™ Processor
The SophonoTM Alpha 2 MPO™ magnetic bone conduction hearing system brings abutment-free bone conduction to your patients with the smallest magnetic implant on the market. The implant lies completely under skin and has low risk of skin issues.1,2 After healing, the skin and hair look normal, with no titanium abutment protruding through the skin like other bone conduction systems. The implant consists of two magnets hermetically sealed in a titanium case. An Attract® magnetic spacer (connected to the external processor) is held in position by the magnetic implant. The processor transmits audio vibrations through the skin into the bone where sound is sensed by the cochlea.
No other implant system - abutment or magnetic, offers the simplicity, low profile and stability of the SophonoTM device.3
The Sophono™ Alpha 2 MPO™ Bone Conduction Hearing Device offers the Lowest Profile ProcessorTake advantage of the performance available with up to 45 dB of feedback free gain!3
Compared to other transcutaneous devices that means up to 7 dB more of feedback free gain! That's 60% louder than our competition!4
The SophonoTM Alpha 2 MPO™ bone conduction hearing device provides improved performance with the highest functional gain, accompanied by outstanding sound quality. Your patients now experience our processor with 45 dB acoustic-mechanical gain, an increase of 16 dB.4 The figure below shows how the SophonoTM device output, measured in force (micronewtons), correlates to the input in decibels sound pressure level (SPL) for varying tones. For audiologists concerned with the acousto-mechanical gain, you can see that along the 60 dB SPL curve there’s an acousto-mechanical gain up to 45 dB at 1,600 KHz. Compared to other bone conduction hearing systems, this proves to be a powerful gain in hearing for your patients. SophonoTM offers more sound amplification (gain) than any other magnetic transcutaneous system!5

Alpha 2 MPO Output more than 105 dB µN4
Compared with other transcutaneous hearing systems:
- More than 4,000 patients have the SophonoTM implant, a safe alternative to more intrusive implants.7
- SophonoTM has the lowest profile processor, a sleek solution that may be hidden under the hair.
Proprietary TET™ TechnologyTranscutaneous Energy Transfer (TET) technology enables maximum transfer from the SophonoTM sound processor, through the patient’s skin and magnetic bone implant, to the working cochlea. TET eliminates up to 20 dB of energy reflection on skin typically associated with percutaneous systems.8
MRI Compatible up to 3 TeslaThe SophonoTM is FDA cleared for MRI conditional up to 3 Tesla.9,10 In non-clinical testing, when positioned parallel to the patient table, the Alpha (M) Magnetic Implant maintained over 95% of its original magnetic strength after 10 insertions into the static magnetic field of a 3-Tesla MR system and a 10-minute imaging sequence in a 3 Tesla Siemens Tri Clinical MRI Scanner (MRC20587). The SophonoTM produces a 5 cm shadow,9 the smallest transcutaneous MRI shadow, and does not require implant removal. You can safely use an MRI only under the following conditions:
- Remove all external components including the OtomagTM Alpha Sound Processor, Magnetic Spacer, Headband or Softband before entering the MRI environment.
- Static magnetic field of 3 Tesla or less
- Spatial gradient field of 720 Gauss/cm or less
- Maximum whole-body averaged specific absorption rate (SAR) of 4 W/kg in the First Level Controlled Mode for a maximum scan time of 15 minutes of continuous scanning (per pulse sequence).
