Audiological Aspects
Limited gain (in general)
1. "Adapter adhesion was sufficient for most of the subjects in our study but varied between one and seven days among participants. Excessive handling of the adapter or rubbing against car seats, armrests, hats etc. as well as variations in mastoid shape, skin type, sweating, or a combination of these factors could cause the observed differences." (Neumann et al. 2019)
Audiological Aspects
Limited gain (in SSD cases)
1. "Observation in clinical practice shows that, still, the majority of [bone conduction device] trial experiences in the general SSD population are negative." (Mertens et al. 2018)
Medical Aspects
Skin issues (mostly valid for non-adhesive systems)
1. "In conclusion, this new, adhesive bone conduction hearing aid has a high patient satisfaction rate while causing no skin irritation or pain." (Dahm et al. 2019)
2. "Bone conduction hearing devices integrated in softbands (BCDSs) are frequently not well accepted by children with conductive hearing loss due to pressure on the head, sweating, or cosmetic stigma." (Neumann et al. 2019)

Patient-reported Aspects
Limited retention / non reliable attachment
1. "Electrical Stimulation via a Cl resulted in a significant reduction in tinnitus loudness (...)." (Van de Heyning et al. 2008)
